MTHFR gene variants and folate metabolism: implications for supplementation with L-5-methyltetrahydrofolate
Nutrients, 2017
Every B vitamin in its active form. L-5-methyltetrahydrofolate (not folic acid). Methylcobalamin (not cyanocobalamin). Pyridoxal-5-phosphate (not pyridoxine HCl). D-pantethine (not calcium pantothenate). Riboflavin-5-phosphate (not riboflavin). Benfotiamine (not thiamine HCl).
Adults: Take 1 capsule once daily with food. Do not exceed the recommended dose. Taking with food improves absorption and reduces the chance of nausea that can occur with high-dose B vitamins on an empty stomach.
Note: Riboflavin-5-phosphate (B2) may cause bright yellow urine. This is a normal and harmless effect of riboflavin metabolism.
Consult a healthcare practitioner before use if you are pregnant or breastfeeding, or if you are taking medications.
Most B complex supplements use folic acid, a synthetic form that must be converted to L-5-MTHF through a multi-step process involving the MTHFR enzyme. Approximately 40 to 60% of the population carries a genetic variant in the MTHFR gene that reduces this conversion by 30 to 70%. L-5-MTHF is the form directly used by the body for methylation reactions, including the remethylation of homocysteine to methionine. This formula provides 1,000mcg of L-5-MTHF, bypassing the MTHFR conversion step entirely.
Methylcobalamin is the active coenzyme form of B12 found in human blood and tissues. Unlike cyanocobalamin, it does not require hepatic conversion and is directly bioavailable. It is better retained in nervous system tissue and functions directly as a cofactor for methionine synthase in the remethylation of homocysteine to methionine.
P-5-P is the active coenzyme form of vitamin B6, directly bioavailable without requiring hepatic conversion from pyridoxine HCl. At 100mg, this formula provides B6 at the tolerable upper intake level. Do not exceed the recommended dose of 1 capsule per day.
D-Pantethine is the active, reduced form of pantothenic acid and a direct precursor to coenzyme A (CoA) central to the citric acid cycle, fatty acid metabolism, and the synthesis of steroid hormones and neurotransmitters. Standard B5 supplements use calcium pantothenate, which requires an additional conversion step.
R5P is the active coenzyme form of riboflavin, immediately bioavailable as a component of FMN and FAD coenzymes essential for the electron transport chain, fatty acid oxidation, and glutathione recycling. Standard riboflavin must be phosphorylated before it can be utilized.
Benfotiamine is a fat-soluble derivative of thiamine with significantly higher oral bioavailability than standard water-soluble thiamine salts. Because it is fat-soluble, it achieves higher blood and tissue concentrations and is better retained in tissues including nervous system tissue.
Inositol hexanicotinate releases niacin more slowly than standard nicotinic acid, reducing the prostaglandin-mediated skin flushing associated with standard niacin. Note: individuals sensitive to nicotinic acid may still experience mild, transient flushing.
Biotin is provided at 50mcg a nutritional support level consistent with daily wellness use, without the laboratory test interference risk associated with high dose biotin supplementation.
Myo inositol is the most abundant and biologically active form of inositol in the body. It functions as a component of phosphatidylinositol, a cell membrane phospholipid involved in intracellular signaling including insulin signal transduction and serotonin receptor function.
Choline is an essential nutrient and precursor to acetylcholine (a neurotransmitter involved in memory and neuromuscular function) and phosphatidylcholine (a primary structural component of cell membranes). Choline bitartrate is a stable, well-absorbed salt form.
Store in a cool, dry place away from direct sunlight and moisture. Keep the bottle tightly sealed after each use. Do not use if the seal is broken or missing. Keep out of reach of children.
Do not exceed the recommended dose of 1 capsule per day. This formula provides vitamin B6 (as P-5-P) at 100mg the tolerable upper intake level for adults. Long-term intake of vitamin B6 above the tolerable upper intake level can cause peripheral neuropathy. Do not combine with other supplements containing vitamin B6 without consulting a healthcare practitioner.
Individuals sensitive to nicotinic acid may experience mild, transient skin flushing due to the inositol hexanicotinate (B3) in this formula. Consult a healthcare practitioner before use if you are pregnant or breastfeeding, or if you are taking medications. Keep out of reach of children.
