Bioclinic Naturals Enhanced B Complex is a once-daily formula that provides full-spectrum B vitamins in their most metabolically active forms. B vitamins are cofactors for many important mechanisms in the body, including nutrient metabolism, energy production, growth and development, and liver function. B vitamins also contribute to immunity, red blood cell production and iron metabolism, as well as healthy skin, hair and nails. This formula contains B vitamins in their active form, such as vitamins B12 (methylcobalamin) and B6 (pyridoxal 5'-phosphate), to support the functioning of the nervous system. It also contains 50 mg of choline and 400 mcg of folate (Quatrefolic). Additionally, this formula contains vitamins B1, B2, B5 and B6, as well as niacin, with added support from biotin and inositol. This convenient all-in-one B-complex is an ideal supplement to help support metabolism, energy and overall health.
Quatrefolic is an active form of folate at the cellular level, the form found in the circulation and the only one that crosses the blood-brain barrier. It may also be the optimal form to prevent neural tube defects. It does not need to be converted to the active form by the enzyme methylene tetrahydrofolate reductase (MTHFR), which is known to exhibit common single nucleotide polymorphisms. Administration of quatrefolic acid was associated with higher peak levels of (6S)-5-MTHF than folic acid and calcium 5-MTHF, even in individuals with high-functioning MTHFR polymorphisms.
Methylcobalamin is a cofactor for B12-dependent enzymes and has direct biological activity. Combined with other B vitamins, it reduces the risk of macular degeneration and migraines, with effectiveness sometimes modulated by MTHFR status.
