5-MTHF & B12 maintains healthy active folate levels by providing 1000 mcg of 5-MTHF and 50 mcg of methylcobalamine (active B12) that are in their active form.
Supports
- Nutrients - Active Folate & B12
- Health - cerebrovascular disease, depression, macular degeneration, migraine disability and hyperhomocysteinemia, with effectiveness sometimes modulated by MTHFR status
Feature Ingredients
- 5-Methyltetrahydrofolate acid (MTHF) - Provides clinically effective dose of the most active and bioavailableform of folate, which bypasses a common bottleneck (MTHFR) in the conversion of folate to its active form.
- Each sublingual tablet also provides 50 mcg methylcobalamin, the primary circulating and biologically active form of vitamin B12
- In a base of active plant extracts, including many organic vegetables, and other bioactive plant compounds, including Theracurmin® curcumin
5-MTHF &B12 provides the most biologically active forms of these two complementary B vitamins.
- (6S)-5-Methyltetrahydrofolate acid (MTHF) is the active form of folate at the cellular level, the form found in circulation and the only to cross the blood brain barrier, and it may be the optimal form for preventing neural tube defects.1 It does not need to be converted to an active form by the enzyme methylene tetrahydrofolate reductase (MTHFR), known to have common single-nucleotide polymorphisms that impair enzymatic activity by as much as 70%.2 Furthermore, quatrefolic acid administration has been associated with higher peak (6S)-5-MTHF levels than both folic acid and calcium 5-MTHF, with higher plasma folate levels even in those with high functioning MTHFR polymorphisms.3,4
- While (6S)-5-Methyltetrahydrofolate acid does not mask a B12 deficiency as folic acid supplementation alone may, these two vitamins have complementary roles in methylation pathways that warrant combined use. Methylcobalamin is the principle circulating form of B12, and is a direct cofactor for B12-dependent enzymes. It has direct biological activity, in contrast to cyanocobalamin which is synthetically derived. When combined with other B vitamins, B12 has been shown to reduce the risk of cerebrovascular disease, depression, macular degeneration, migraine disability and hyperhomocysteinemia, with effectiveness sometimes modulated by MTHFR status.5-9

Although several classes of drugs, such as aminoglycosides, anticonvulsants, bile acid sequestrants, and proton pump inhibitors, antihyperglycemic medications (Metformin), acne therapy (isotretinoin) are known to either interfere with B12 absorption or function, there are no known negative interactions caused by B12 supplementation with any medications.10-13 Metformin has been shown to deplete B12 and folate, and supplementation with B12 only in diabetics may be preferable.14
Side Effect Risks
