Formulation Notes

How it works: Liquid B-12 is a complete B-complex formula that is high in Vitamin B-12. B vitamins are often found together because, although each works independently of the others, they often function together in common metabolic pathways. For example, most of the B vitamins are involved in energy production pathways. In addition, Vitamin B-12 and folic acid are both essential for the synthesis of DNA during cell division and therefore are important for rapidly multiplying cells, such as blood cells. This formula contains 5,000 mcg of B-12 in three different forms to optimize its utilization.

Cautions/interactions: Generally well tolerated even at high levels of intake.

3 forms of B-12 for maximum utilization Complete liquid B-complex

Not manufactured with wheat, gluten, soy, milk, egg, fish or shellfish ingredients.
