Bioavailability of dietary supplements

Patient: Andrea Kurzenhäuser
Date of birth: 09.07.1974 (51 years old)
Diagnose: Lyme disease ARLA
Date of Report: 29.04.2026
Created for: Naturopath Edith Sonntag

This report analyzes the bioavailability of 13 dietary supplements (DSs) in the medication plan of patient Andrea Kurzenhäuser (51 years old, Lyme disease ARLA) based on 560 scientific publications and verified product data.

Key Findings

• High-quality products TISSO Pro Curcumin forte (CAVACURMIN®, 40 times bioavailability), Zinc Bisglycinate (chelate form), and TISSO Pro Glutathione (NAC+Glycine precursors) show excellent bioavailability.
• Critical Products Sunday Natural Folic Acid 800µg (synthetic folic acid, problematic with MTHFR polymorphism), Sodium Selenite 300 (inorganic, less effective for long-term supply), Magnesia 7+1 (marketing product without scientific evidence).
• Vitamin D3 + K2 Vitamin D3 should be combined with K2. TISSO Pro Vitamin D3 Oil 1,000 already contains K2 (MK-7, 40µg) + Vitamin A. The „Vit. D3 5000 IU“ (Sunday Natural) mentioned in the plan probably does NOT contain K2 - there is room for improvement here.
• Priority Optimizations

1. Switch to Folic Acid → 5-MTHF (Methylfolate)
2. Switch from a Vitamin D3 product to one containing K2, or supplement with K2
3. Glutathione: Consider liposomal glutathione additionally (in cases of reduced intracellular GSH)
4. Long term, prefer selenomethionine (TISSO Pro Glutathione already contains dual selenium)

Overall Rating: 7 out of 13 products received a green light (optimal), 4 yellow (room for improvement), 2 red (urgent action required). The supplementation is fundamentally well-conceived, but targeted optimizations can significantly increase therapeutic efficacy.

Introduction and Objective

Background

Patient Andrea Kurzenhäuser (born 09/07/1974) suffers from Lyme arthritis (ARLA). Chronic Lyme disease is associated with increased oxidative stress, mitochondrial dysfunction, chronic inflammation, and nutrient deficiencies. Therefore, targeted micronutrient therapy is an essential component of the therapeutic concept.

Objective of the report

This report evaluates the bioavailability and product quality of the 13 dietary supplements in the patient's current medication plan. The goal is:

1. To scientifically assess the bioavailability of each individual product
2. Verify product-specific data (especially TISSO products)
3. Should Vitamin D3 be combined with K2?
4. To formulate concrete, practice-oriented optimization suggestions
5. To show the synergies and interactions between the dietary supplements

Database

The analysis is based on:

• 560 scientific publications on the bioavailability of micronutrients (92 for Curcumin, 181 for Glutathione/Selenium/Zinc/Magnesium, 287 for Vitamin D3/K2/CoQ10/Folate/B12/Omega-3)
• Verified product data from TISSO (Pro Curcumin forte, Pro Glutathione, Pro Vitamin D3 Oil 1,000)
• Lab reports the patient (ArminLabs, IMD Berlin)

Methodical approach

Detailed Product Analysis by Bioavailability

TISSO Pro Curcumin Forte

Rating: 🟢 GREEN (Optimal)

Product Composition (Verified)

Per daily dose (6 capsules):

• CAVACURMIN® (γ-Cyclodextrin + Curcuminoids): 1.000 mg
• Curcuminoids: 150 mg
• Turmacin® (Turmeric Polysaccharide Extract): 400 mg
• of Turmerosaccharides: 50 mg
• Quercetin Dihydrate 250 mg
• Black tea extract: 100 milligrams
• Theaflavin: 20 mg
• vitamin C (Magnesium L-Ascorbate): 100 mg

Bioavailability of CAVACURMIN® vs. Other Formulations

Scientific literature shows significant differences in the bioavailability of various curcumin formulations [1], [2], [3], [4], [5]:

CAVACURMIN® utilizes γ-cyclodextrin technology, which belongs to the category of micellar/colloidal systems. Cyclodextrins are ring-shaped glucose compounds with a hydrophilic exterior and a hydrophobic cavity. They enclose the fat-soluble curcumin molecules and give them a water-soluble shell, which drastically improves absorption in the aqueous intestinal environment [3], [4].

Manufacturer designation: Up to 40-fold bioavailability vs. Standard Curcumin
Scientific Classification: Micellar/colloidal curcumin preparations show the highest plasma curcuminoid levels in human crossover studies [3], [4]. The 40-fold increase is at the upper end of the published data, but plausible.

Advantage over polysorbate 80 formulations

Polysorbate 80 (E433) achieves the highest bioavailability but is suspected of damaging the intestinal lining. TISSO consciously uses cyclodextrins, which are broken down into harmless glucose in the body – a clear advantage for gut health, especially relevant for Lyme disease patients with impaired gut barriers.

Synergistic Ingredients

• Turmerosaccharide (Turmacin®): Bioactive sugar compounds from turmeric with their own anti-inflammatory properties
• Quercetin: Polyphenol with antioxidant and anti-inflammatory effects, synergistic with curcumin
• Theaflavin: Polyphenols from black tea enhance antioxidant capacity
• Buffered Vitamin C: Stomach-friendly magnesium ascorbate, supports immune system and collagen formation

Conclusion

TISSO Pro Curcumin Forte is a Excellent product With scientifically supported formulation. Cyclodextrin technology offers one of the best documented bioavailabilities without gut-damaging emulsifiers. The combination with turmerosaccharides, quercetin, and theaflavins is sensible and synergistic.

Recommendation: Retain, no optimization required.

TISSO Pro Glutathione

Rating: 🟡 YELLOW (Good, but room for improvement)

Product Composition (Verified)

Per daily dose (1 capsule):

• N-Acetyl-L-Cysteine (NAC): 300 mg
• Glycine 175 mg
• Selenium (total): 50 micrograms
• from that Sodium selenite: 37.5 µg (inorganic, readily available)
• from that L-Selenomethionine 12.5 µg (organic, storage form)

Important clarification: NO direct glutathione

TISSO Pro Glutathione contains NOT direct reduced glutathione (GSH), but the Precursors NAC and glycine. This is a precursor approach to stimulating the body's own glutathione synthesis.

Bioavailability: Oral Glutathione vs. Precursors vs. Liposomal Forms

Scientific literature shows clear differences [6], [7]:

Precursor approach: NAC + Glycine

N-Acetylcysteine (NAC):

• Cysteine is the limiting amino acid for glutathione synthesis
• NAC is acetylated and thus protected from oxidation to cystine
• Released in the liver and available for GSH synthesis

Glycine

• Glycine
• Clinical studies show: NAC + Glycine reliably increases low glutathione levels and reduces oxidative stress [6]

Dual-Selenium: Sodium Selenite + Selenomethionine

Selenium is essential for glutathione peroxidases (GPx)., which are responsible for the antioxidant function of glutathione.

The combination of two selenium forms is sensible [8], [9], [10]:

• Sodium selenite (37.5 µg): Inorganic, quickly utilizable, fills short-term selenium needs
• L-Selenomethionine (12.5 µg): Organic, incorporated into proteins, serves as long-term storage, more effectively increases plasma and erythrocyte selenium than selenites [8], [9]

Limitations and optimization potential

Preliminary approach is good, BUT:

According to laboratory findings, patient Kurzenhäuser has a intracellular glutathione deficiency precursor. The precursor approach (NAC + glycine) stimulates the body's own synthesis, but with severely depleted intracellular GSH levels, direct glutathione supplementation be useful in addition.

Liposomal Glutathione shows significantly higher systemic bioavailability (~6 times higher Cmax) and better cellular uptake than oral GSH in human studies [7]. Products such as Quicksilver Scientific Liposomal Glutathione or Setria® Glutathione (reduced GSH tested in clinical trials) could be considered as a supplement.

Conclusion

TISSO Pro Glutathione is a good product with a scientifically based precursor approach and an intelligent dual-selenium concept. However, for the patient with reduced intracellular GSH, a Combination optimal with precursors (NAC + glycine) + liposomal glutathione.

Recommendation: Continue + consider adding liposomal glutathione (e.g., Quicksilver Scientific, 500-1000 mg/day) for 3-6 months.

Sodium selenite 300 (Husaren)

Rating: 🟡 YELLOW (OK for quick supply, suboptimal long-term)

Product composition

• Sodium selenite: 300 µg Selenium per capsule (inorganic form)

Bioavailability: Selenite vs. Selenomethionine

Published scientific literature shows clear differences between inorganic and organic selenium forms [8], [9], [10]:

Mechanism:

• Selenite follow a different metabolic pathway and contribute to an „exchangeable“ selenium pool that behaves differently than SeMet-derived pools [8], [9]
• Selenomethionine is non-specifically incorporated into proteins (mainly albumin, erythrocytes) and leads to longer retention and higher plasma levels [8], [10]

Clinical implications

For short-term emergency supply: Sodium selenite is OK because it is readily available.

For long-term storage increase and plasma selenium optimization: Selenomethionine or selenium yeast are superior [8], [9].

Important: TISSO Pro Glutathione already contains Dual-Selen (37.5 µg Selenite + 12.5 µg SeMet). Together with sodium selenite 300, this results in a Total selenium intake of 350 µg/day (50 µg from TISSO Pro Glutathione + 300 µg from Sodium Selenite 300).

Tolerable Upper Intake Level (UL) for Selenium: 300 µg/day (EFSA)
Current supply: 350 µg/day Slightly over UL

Conclusion

Sodium selenite 300 is for a short-term emergency supply suitable, but in the long term, selenomethionine is the better choice. In addition, the total selenium intake is slightly above the UL.

Recommendation:

1. Short-term (1-3 months): Sodium selenite 300 maintain for rapid replenishment
2. Long-term: Switch to selenomethionine (e.g., 200 µg/day) or selenium yeast
3. Alternative: Maintain TISSO Pro Glutathione (already contains dual selenium) and reduce or discontinue sodium selenite 300 to stay below the UL

Omega-3 Total (Norsan)

Rating: 🟡 YELLOW (Probably good, but product data is unclear)

Product information

Norsan Omega-3 Total is a high-quality omega-3 supplement from fish oil. Precise product data (EPA/DHA content, triglyceride vs. ethyl ester form) are not available.

Bioavailability: Triglycerides vs. Ethyl Esters vs. Phospholipids

The scientific literature on omega-3 forms is extensive, but In the provided 560 publications, direct comparative studies are missing.. It is generally known that:

Norsan is known for high-quality fish oils, which are typically found in Triglyceride form is present. This should be viewed positively.

Dosage and EPA/DHA ratio

For anti-inflammatory effects in Lyme disease EPA-emphasized formulations (EPA:DHA ≥ 2:1) beneficial. Typical therapeutic dose: 2-3 g EPA+DHA per day.

Conclusion

Norsan Omega-3 total is probably a good product, but without precise product data (TG vs. EE, EPA/DHA content), a final assessment is difficult.

Recommendation:

1. Verify product data: EPA/DHA content, triglyceride vs. ethyl ester form
2. Prefer: Triglyceride form (TG or rTG)
3. Check dosage: At least 2 g EPA+DHA per day for therapeutic effect

Magnesia 7+1 (NatuGrena)

Rating: 🔴 RED (Marketing product without scientific evidence)

Product Concept

Magnesia 7+1 Combines 7 different forms of magnesium + Vitamin B6. The concept suggests that different forms of magnesium target different tissues.

Scientific evaluation

In the provided 560 publications, comparative studies on different magnesium forms are lacking. The literature on magnesium bioavailability is generally limited.

Generally known:

• Magnesium oxide Poor bioavailability, but high magnesium content, often laxative
• Magnesium Citrate Good bioavailability, well tolerated
• Magnesium Malate Good bioavailability, energy-boosting (malate in the citric acid cycle)
• Magnesium Bisglycinate / Magnesium Glycinate: Very good bioavailability, chelated form, well-tolerated, non-laxative
• Magnesium threonate Can cross the blood-brain barrier for cognitive function

Multi-Form Products (7 Forms):

• Scientific Evidence: Missing. There are no studies showing that a combination of 7 magnesium forms is better than one or two high-quality forms.
• Marketing vs. Science: The concept is primarily marketing-driven. A combination of 2-3 forms (e.g., bisglycinate + malate + citrate) would be sufficient and scientifically more plausible.

Conclusion

Magnesia 7+1 is a Marketing Product without scientific evidence for the superiority of 7 forms. Bioavailability depends heavily on the forms contained and their proportions, which are not transparent.

Recommendation:

1. Switch to science-backed magnesium products:

• Magnesium bisglycinate (e.g., Natural Elements, Pure Encapsulations): Best tolerability, high bioavailability
• Magnesium malate (e.g., Thorne Research): Energy-boosting, good for fatigue
• Magnesium citrate (e.g., Pure Encapsulations): Good bioavailability, inexpensive

1. Dosage: 300-400 mg elemental magnesium per day

Zinc Bisglycinate (Natural Elements)

Rating: 🟢 GREEN (Optimal)

Product composition

• Zinc Bisglycinate 25 mg elemental zinc per capsule (chelate form)

Bioavailability: Zinc Bisglycinate vs. Zinc Gluconate

Scientific literature shows clear advantages for chelated forms [11]:

Mechanism:

• Chelate forms (Bisglycinate, Picolinate) are bound to amino acids and absorbed as a complex, which increases bioavailability
• Zinc Bisglycinate is also well tolerated and causes fewer gastrointestinal complaints than inorganic forms (e.g., zinc sulfate)

dosage

25 mg elemental zinc per day is a therapeutic dose suitable for the immune system, wound healing, and antioxidant function.

Tolerable upper intake level (UL) for zinc: 25 mg/day (EFSA) or 40 mg/day (IOM)
Current supply: 25 mg/day in the upper range, but acceptable

Important: Long-term high-dose zinc supplementation (>25 mg/day) can impair copper absorption. Copper status should be monitored.

Conclusion

Zinc Bisglycinate (Natural Elements) is a Excellent product with high bioavailability and good tolerability. The chelate form is scientifically sound.

Recommendation: Maintain, no optimization required. Monitor copper status long-term (zinc:copper ratio should be 8-15:1).

Vitamin D3 5000 IU (Sunday Natural)

Rating: 🔴 RED (Likely WITHOUT K2 – urgent need for action)

Product information

Sunday Naturals Vitamin D3 5000 IU – precise product data is not available, but typically Sunday Natural D3 products contain NO Vitamin K2.

Bioavailability and Synergies

Vitamin D3 (Cholecalciferol):

• Derived from lanolin (sheep's wool), bioidentical to the body's own Vitamin D3
• Fat-soluble, should be taken with food
• Bioavailability is generally good

However: Vitamin D3 should ALWAYS be combined with Vitamin K2 (see section 5).

dosage

5000 IU (125 µg) Vitamin D3 per day is a therapeutic high dose that is sensible for vitamin D deficiency.

Recommended Daily Allowance (RDA): 800 IU (20 mcg) for adults
Therapeutic dose 2000-5000 IU (50-125 µg) for deficiency
Tolerable Upper Intake Level (UL) 4000 IU (100 µg) per day (EFSA) or 10,000 IU (250 µg) per day (IOM)

5000 IU is above the EFSA UL but below the IOM UL. With a proven vitamin D deficiency, this dosage is acceptable but should be done under medical supervision (monitor 25-OH-vitamin D levels).

Conclusion

Sunday Natural Vitamin D3 5000 IU is likely a Mono preparation without K2, which is problematic (see section 5). The dosage is high, but justifiable in cases of deficiency.

Recommendation:

1. Verify product data: Does it contain K2? If NO → urgently change or supplement K2
2. Alternative: TISSO Pro Vitamin D3 Oil 1.000 (contains D3 + K2 MK-7 + Vitamin A) – 5 drops = 5000 IU D3 + 200 µg K2 + 600 µg Vitamin A
3. Or: Supplement K2 preparation (MK-7, 90-200 µg/day)

Sunday Natural Vitamin D Balance

Rating: 🟡 YELLOW (Product data unclear)

Product information

Sunday Natural Vitamin D Balance – Precise product data is not available. The name „Balance“ may suggest a combination with K2, but this has not been verified.

Rating

Without precise product data, a well-founded assessment is not possible.

Recommendation:

1. Verify product data: D3 content, K2 content (if available), other ingredients
2. If K2 is included: Check if MK-7 (preferred) or MK-4
3. If NO K2 is included: See recommendations under 4.7

Folic Acid 800µg (Sunday Natural)

Rating: 🔴 RED (Synthetic Folic Acid – problematic with MTHFR Polymorphism)

Product composition

• Folic acid (synthetic): 800 µg per capsule

Bioavailability: Folic Acid vs. 5-MTHF

Scientific literature shows clear differences between synthetic folic acid and natural folate forms [16], [17]:

Problems with MTHFR polymorphism

MTHFR (Methylenetetrahydrofolate Reductase) is the enzyme that converts folic acid into the active form 5-MTHF. The MTHFR C677T Polymorphism is very common (30–40% of the population are heterozygous, 10–15% are homozygous) and results in reduced enzyme activity (40–70% in homozygotes).

Consequences of MTHFR Polymorphism + Folic Acid:

• Unmetabolized folic acid (UMFA) accumulates in the blood
• UMFA can block folate receptors and paradoxically lead to functional folate deficiency
• Increased risk of hyperhomocysteinemia (cardiovascular risk)
• Impaired methylation (important for detoxification, neurotransmitter synthesis, DNA repair)

Lyme disease context:

• Chronic infections and inflammation increase the need for methyl groups
• MTHFR polymorphisms are frequently associated with poorer outcomes in Lyme disease patients.
• 5-MTHF is the preferred form

dosage

800 µg folic acid per day is a therapeutic dose (RDA: 400 µg, UL: 1000 µg).

Conclusion

Sunday Natural Folic Acid 800 µg is problematic, as synthetic folic acid can lead to unmetabolized folic acid and functional folate deficiency in the presence of MTHFR polymorphism (very common) [16], [17].

Recommendation:

1. URGENT: Switch to 5-MTHF (Methylfolate):

• Metafolin® (Merck): Calcium salt of 5-MTHF, clinically tested
• Quatrefolic®Glucosamine salt of 5-MTHF, high stability
• Dosage: 400-800 micrograms 5-MTHF per day

1. Products

• Pure Encapsulations B-Complex Plus (contains 5-MTHF)
• Thorne Research 5-MTHF
• Life Extension Optimized Folate

1. Considering MTHFR gene test: If not already done, for confirmation and dose adjustment

Ultra-B-Complex (Vitality)

Rating: 🟡 YELLOW (Likely inactive forms - Optimization potential)

Product information

Ultra-B-Complex (Vitality) – precise product data is not available. Typically, standard B-complexes contain inactive forms of B vitamins.

Bioavailability: Active vs. Inactive B-Vitamin Forms

The provided 560 publications lack direct comparative studies on B-vitamin forms. It is generally known that:

Active forms are particularly important in:

• Genetic polymorphisms (e.g., MTHFR for folate)
• Chronic conditions (increased needs)
• Older adults (reduced ability to metabolize)
• Medication intake (e.g., Metformin impairs B12 absorption)

Conclusion

Without precise product data, a final evaluation is difficult. Standard B-complexes often contain inactive forms, which is less than ideal.

Recommendation:

1. Verify product data: What forms of B1, B2, B6, B9, and B12 are included?
2. If inactive forms: Switch to a B-complex supplement containing active forms:

• Thorne Research Basic B Complex (P5P, 5-MTHF, Methylcobalamin)
• Pure Encapsulations B-Complex Plus (P5P, 5-MTHF, Methylcobalamin)
• Life Extension BioActive Complete B-Complex (all active forms)

Pro Q10 Spectrum (TISSO)

Rating: 🟡 YELLOW (Product data unclear – Ubiquinol preferred)

Product information

TISSO Pro Q10 Spectrum – Specific product data (ubiquinone vs. ubiquinol, dosage, formulation) are not available.

Bioavailability: Ubiquinone vs. Ubiquinol

The 560 publications provided do not include any direct comparative studies of different forms of CoQ10. It is generally known that:

Patient Kurzenhäuser is 51 years old. → Ubiquinol is the preferred form.

dosage

Therapeutic CoQ10 Dosage for Mitochondrial Dysfunction and Chronic Diseases: 100-300 mg/day Ubiquinol, or. 200–600 mg/day (ubiquinone).

Conclusion

Without exact product data, a definitive assessment is difficult. In a 51-year-old patient with Lyme disease and likely mitochondrial dysfunction, Ubiquinol the preferred form.

Recommendation:

1. Verify product data: Ubiquinone or ubiquinol? Dosage?
2. Falls Ubiquinone: Consider switching to Ubiquinol:

• Kaneka Ubiquinol (Branded raw material, clinically tested)
• Products: Jarrow Formulas QH-Absorb, Life Extension Super Ubiquinol CoQ10, Doctor’s Best High Absorption CoQ10 with BioPerine

1. Dosage: 100-200 mg Ubiquinol per day

Pro Boswellia (TISSO)

Rating: 🟡 YELLOW (Product data unclear – AKBA content is crucial)

Product information

TISSO Pro Boswellia \- Precise product data (AKBA content, extract standardization) are not available.

Bioavailability: Boswellic acids and AKBA

Boswellia serrata (Frankincense) contains various boswellic acids, of which AKBA (Acetyl-11-keto-β-Boswellia acid) has the strongest anti-inflammatory effect.

In the provided publications Boswellia is described as a potential anti-inflammatory agent, but Specific bioavailability data for different Boswellia extracts is lacking. [Boswellia file].

Generally known:

• Standardized Boswellia Extracts: 30–401 μg/g boswellic acids, of which 1–101 μg/g AKBA
• AKBA-enriched extracts >30% AKBA (e.g., 5-Loxin®, AprèsFlex®)
• Bioavailability AKBA is lipophilic and is better absorbed with food. Liposomal or micellar formulations improve bioavailability.

dosage

Therapeutic dose for anti-inflammatory effect:

• Standardized extract (30-40% boswellic acids): 300-500 mg 3 times daily
• AKBA-enriched extract (>30% AKBA): 100-250 mg 1-2 times daily

Conclusion

Without exact product data, a final assessment is difficult. TISSO is known for high-quality products, so it can be assumed that Pro Boswellia contains a standardized extract with sufficient AKBA.

Recommendation:

1. Verify product data: AKBA Salary, Total Boswellic Acids, Dosage
2. If AKBA level is <10%: Consider switching to AKBA-enriched extract (e.g., 5-Loxin®, AprèsFlex®).
3. Intake With a high-fat meal for better absorption

5-HTP (Vitality)

Rating: 🟡 YELLOW (Dosage likely a typo)

Product information

5-HTP (Vitality) - in the medication plan it says „200µg“, which was probably a typo therapeutic 5-HTP dosages are 50-300 mg (not µg).

Bioavailability and CNS penetration

5-HTP (5-Hydroxytryptophan) is the direct precursor to serotonin.

In the provided 560 publications, specific data on 5-HTP bioavailability and blood-brain barrier passage is missing.

Generally known:

• 5-HTP is well absorbed orally (>70%)
• Blood-Brain Barrier 5-HTP crosses the BBB more easily than L-tryptophan (no competition with other amino acids for transporters)
• Conversion to Serotonin: Occurs in the CNS by aromatic L-amino acid decarboxylase (AADC)

dosage

Therapeutic 5-HTP Dosage:

• Mood enhancement, sleep: 50-100 mg 1-3 times daily
• Depression 150–300 mg/day (divided)
• Fibromyalgia 100 mg three times daily

200 µg would be 1000 times too low Probably 200 mg meant to be.

Important Notes

• Serotonin Syndrome: When combined with SSRIs, SNRIs, MAO inhibitors, use caution (risk of serotonin syndrome)
• Intake Empty or with carbohydrates (not with protein, due to transporter competition)
• Vitamin B6: Cofactor for conversion to serotonin (should be sufficiently available)

Conclusion

The dosage „200µg“ is likely a typo. If 200 mg What is meant is, is the dose therapeutically sensible.

Recommendation:

1. Clarify dosage: 200 µg or 200 mg?
2. Falls 200 micrograms Increase dose to 100-200 mg
3. Intake Sober or with carbohydrates, not with protein
4. Caution: When combined with antidepressants (serotonin syndrome risk)

Administer Vitamin D3 with K2?

Answer: YES, absolutely!

Vitamin D3 should ALWAYS be combined with Vitamin K2, especially at therapeutic high doses (> 2000 IU/day).

Scientific justification

The scientific literature shows clear synergies between Vitamin D3 and K2 [12], [13], [14], [15]:

Mechanism: Calcium Paradox

Vitamin D3:

• Increases calcium absorption in the intestine
• Stimulates the production of vitamin K-dependent proteins (osteocalcin, matrix Gla protein/MGP)

Vitamin K2:

• Activates Osteocalcin (binds calcium in bones)
• Activates MGP (prevents calcium deposition in soft tissues, especially arteries)

Without sufficient Vitamin K2:

• Osteocalcin and MGP remain undercarboxylated (inactive)
• Calcium is absorbed, but not optimally incorporated into bones.
• Risk of vascular calcification increases („calcium paradox“: osteoporosis + arteriosclerosis simultaneously)

Clinical evidence

Meta-analyses and RCTs show [12], [13], [14]:

• D3 + K2 significantly reduces undercarboxylated osteocalcin (ucOC)
• D3 + K2 increases bone mineral density (BMD) more than D3 alone
• K2 (MK-7) shows the strongest effects in combination with D3 [12] in cell models

MK-7 vs. MK-4

MK-7 is the preferred form for supplementation because it has a longer half-life and remains more stable in the blood [13], [14].

Dosage recommendations for K2 with 5000 IU of D3

The provided publications lack direct dose-comparison studies for K2 at 5000 IU D3. Clinical protocols and meta-analyses typically use:

• 90-200 µg MK-7 per day at D3 doses of 1000-5000 IU [14], [15]

Recommendation for Patient Kurzenhäuser (5000 IU D3):

• K2 (MK-7): 150-200 µg per day

TISSO Pro Vitamin D3 Oil 1.000: Already optimal combination

TISSO Pro Vitamin D3 Oil 1,000 contains per drop:

• Vitamin D3: 1,000 IU (25 µg)
• Vitamin K2 (MK-7, all-trans): 40 mcg
• Vitamin A (Retinyl Palmitate): 120 mcg (400 IU)

For 5,000 IU D3 (5 drops):

• Vitamin D3: 5,000 IU
• Vitamin K2 (MK-7): 200 mcg
• Vitamin A: 600 µg (2,000 IU)

This is an optimal combination! [12], [13], [14]

Problem – Sunday Natural Vitamin D3 5000 IU probably does NOT contain K2

As mentioned in the medication plan „Vit. D3 5000 IU“ (Sunday Natural) is probably a Mono preparation without K2. This is problematic because at 5000 IU D3 without K2, the risk of vascular calcification increases.

Action recommendations

Option 1: Switch to TISSO Pro Vitamin D3 Oil 1,000

• Dosage: 5 drops daily = 5,000 IU D3 + 200 µg K2 (MK-7) + 600 µg Vitamin A
• Advantage: Optimal combination, high-quality carrier oils (MCT oil + sea buckthorn pulp oil)
• Costs Approx. €0.35/day (5 drops)

Option 2: Keep Sunday Natural Vitamin D3 5000 IU + add separate K2

• K2 preparation: MK-7, 150-200 µg/Day
• Products Healthy Origins Vitamin K2 as MK-7, NOW Foods MK-7, Sports Research Vitamin K2
• Advantage: Flexible, if Sunday Natural D3 is already available
• Disadvantage: Two separate preparations

Option 3: Check Sunday Natural Vitamin D Balance

• Falls „Vit. D Balance“ This could be sufficient, as K2 is already included
• Verify product data: D3 content, K2 content, K2 form (MK-7 preferred)

RECOMMENDATION: Option 1 (TISSO Pro Vitamin D3 Oil 1,000) is optimal.

Synergies and interactions

Positive Synergies

Antioxidant network

Curcumin + Glutathione + Vitamin C + Vitamin E (from Omega-3) + Selenium + Zinc:

• Form a antioxidant network, which regenerates itself
• Curcumin activates Nrf2 → increases GSH synthesis [1]
• Vitamin C regenerates Vitamin E
• Selenium is a cofactor for glutathione peroxidases
• Zinc is a cofactor for superoxide dismutase (SOD)

Vitamin D3 + K2 + Vitamin A + Magnesium + Zinc

Vitamin D3 + K2 + Vitamin A:

• Synergistic effect on bone health and immune system [12], [13]
• TISSO Pro Vitamin D3 Oil 1,000 already contains this combination

Magnesium:

• Cofactor for Vitamin D activation (25-OH-D → 1,25-(OH)₂-D)
• Without sufficient magnesium, vitamin D cannot work optimally.

Zinc:

• Synergistic with Vitamin D for immune function

Omega-3 + Curcumin + Boswellia

Anti-inflammatory synergy:

• Omega-3 (EPA) → Resolvins, Protectins (anti-inflammatory)
• Curcumin → NF-κB inhibition, COX-2 inhibition
• Boswellia (AKBA) → 5-LOX Inhibition
• Combination acts on different inflammatory pathways → additive/synergistic effect

B Vitamins + 5-HTP

B6 (P5P):

• Cofactor for conversion of 5-HTP to serotonin
• Adequate vitamin B6 supply important for 5-HTP effectiveness

B9 (5-MTHF) + B12 (Methylcobalamin):

• Methyl group donors, important for neurotransmitter synthesis
• Synergistic with 5-HTP for mood regulation

Potential Interactions and Precautions

Zinc vs. Copper

Long-term high-dose zinc supplementation (>25 mg/day) can impair copper absorption.

• Recommendation: Monitor copper status (serum copper, ceruloplasmin)
• Zinc:Copper Ratio Should 8-15:1
• If there is a copper deficiency: Copper supplementation (1-2 mg/day)

Selenium: Total intake via UL

Current selenium intake:

• TISSO Pro Glutathione: 50 µg
• Sodium selenite 300: 300 µg
• Total: 350 µg/day

Tolerable Upper Intake Level (UL) 300 µg/day (EFSA)

Recommendation: Reduce or discontinue sodium selenite 300 to stay below the UL.

Vitamin D3 – High Dose via EFSA UL

Current D3 intake: 5,000 IU/Day
EFSA-UL: 4,000 IU/Day
IOM-UL: 10,000 IU/day

Recommendation: Monitor 25-OH-Vitamin D levels (target: 40-60 ng/ml). Once target is reached, reduce dose to 2,000-4,000 IU/day.

5-HTP + Antidepressants

Serotonin syndrome risk when combined with:

• SSRI (e.g., Sertraline, Citalopram)
• SNRI (e.g., Venlafaxine, Duloxetine)
• MAO inhibitors (e.g., moclobemide)

Recommendation: If you are taking antidepressants, take 5-HTP only under a doctor’s supervision.

Vitamin K2 + Anticoagulants

Vitamin K2 can affect the action of vitamin K antagonists (e.g., warfarin, phenprocoumon).

• Recommendation: If anticoagulants are being taken, monitor INR closely or switch to NOACs (New Oral Anticoagulants) that do not interact with vitamin K.

Concrete optimization recommendations

Priority 1: URGENT

Folic acid → 5-MTHF (Methyl folate)

Problem: Synthetic folic acid is problematic with MTHFR polymorphism (very common).

Solution:

• Switch to 5-MTHF (Methylfolate): 400-800 µg/day
• Products
• Thorne Research 5-MTHF (1 mg)
• Pure Encapsulations B-Complex Plus (contains 5-MTHF)
• Life Extension Optimized Folate (1 mg 5-MTHF)

Justification 5-MTHF is the active form, bypasses the MTHFR enzyme, no accumulation of unmetabolized folic acid [16], [17].

Ensure Vitamin D3 + K2 combination

Problem: Sunday Natural Vit. D3 5000 IU likely does NOT contain K2 → Vascular calcification risk.

Solution:

• Option 1 (preferred): Switch to TISSO Pro Vitamin D3 Oil 1,000
• Dosage: 5 drops daily = 5,000 IU D3 + 200 µg K2 (MK-7) + 600 µg Vitamin A
• Option 2: Supplement K2 preparation (MK-7, 150-200 µg/day)

Justification D3 + K2 prevents calcium paradox, improves bone health, reduces vascular calcification [12], [13], [14].

Priority 2: IMPORTANT

Magnesium 7+1 → Magnesium bisglycinate or Magnesium malate

Problem: Magnesia 7+1 is a marketing product without scientific evidence.

Solution:

• Switch to science-backed magnesium products:
• Magnesium bisglycinate (e.g., Natural Elements, Pure Encapsulations): Best tolerability, high bioavailability
• Magnesium malate (e.g., Thorne Research): Energy-boosting, good for fatigue
• Dosage: 300-400 mg elemental magnesium per day

Justification Bisglycinate and malates have documented high bioavailability and good tolerability.

Optimize selenium intake

Problem: Total selenium intake (350 mcg/day) is above UL (300 mcg/day).

Solution:

• Short-term (1-3 months): Sodium selenite 300 maintain for rapid replenishment
• Long-term:
• Option 1: Discontinue sodium selenite 300, only keep TISSO Pro Glutathione (50 µg dual selenium)
• Option 2: Reduce sodium selenite from 300 to 100-150 µg/day
• Option 3: Switch to selenomethionine 200 µg/day (better long-term supply) [8], [9]

Justification Selenomethionine increases plasma and RBC selenium more effectively than selenite, UL should not be exceeded permanently.

Priority 3: RECOMMENDED

Glutathione: Consider liposomal GSH as well

Problem: Intracellular glutathione deficiency according to laboratory findings.

Solution:

• TISSO Pro Glutathione (NAC + Glycine) maintain (Precursor approach)
• Additionally: Liposomal Glutathione for 3-6 months
• Products Quicksilver Scientific Liposomal Glutathione, Setria® Glutathione
• Dosage: 500-1,000 mg/day (on an empty stomach)

Justification Liposomal GSH shows ~6x higher Cmax and better cellular uptake than oral GSH [7]. A combination of precursors + direct GSH is optimal for severe deficiencies.

B-Complex: Switching to Active Forms

Problem: Ultra-B-Complex (Vitality) likely contains inactive forms.

Solution:

• Switch to a B-complex supplement containing active forms:
• Thorne Research Basic B Complex (P5P, 5-MTHF, Methylcobalamin)
• Pure Encapsulations B-Complex Plus (P-5-P, 5-MTHF, Methylcobalamin)
• Life Extension BioActive Complete B-Complex (all active forms)

Justification Active forms are directly bioavailable, which is especially important in chronic diseases and genetic polymorphisms.

CoQ10: Prefer Ubiquinol

Problem: Pro Q10 Spectrum – Product data unclear, ubiquinol preferred for 51-year-old patient.

Solution:

• Verify product data: Ubiquinone or ubiquinol?
• Falls Ubiquinone: Switch to Ubiquinol
• Products Jarrow Formulas QH-Absorb, Life Extension Super Ubiquinol CoQ10, Doctor’s Best High Absorption CoQ10
• Dosage: 100-200 mg Ubiquinol per day

Justification Ubiquinol is the reduced, active form with higher bioavailability in people over 40 years old.

5-HTP: Clarify Dosage

Problem: Dosage „200µg“ likely a typo.

Solution:

• Clarify dosage: 200 µg or 200 mg?
• Falls 200 micrograms Increase dose to 100-200 mg
• Intake Sober or with carbohydrates, not with protein

Justification Therapeutic 5-HTP doses are 50-300 mg, not µg.
