Why you’ll love Vitamin B-Complex

Traditional B-complex supplements use synthetic forms that your body has to convert before using—an extra step that can affect how much is available for your body to absorb.

Vitamin B-Complex features nature-identical L-methylfolate & methylcobalamin B12, plus 10 other high-potency B vitamins and complementary nutrients, to support energy production, a balanced stress response, and healthy homocysteine levels.

Frequently Asked Questions

B12 is one of eight essential B vitamins, and is a common source of deficiency. B12 plays a critical role in energy production and nervous system health, but it’s just one in a whole family of eight B vitamins.

A B-complex supplement provides all eight, supporting energy production, stress response, and homocysteine levels together. Some B-complex supplements feature nature-identical, activated forms, which are more readily available for your body to use.

L-methylfolate is the nature-identical, active form of folate (vitamin B9)—meaning it's ready for your body to use without conversion. Most conventional supplements use folic acid, which the body has to convert before it can be used. This step can be a barrier for those with genetic variations that affect folate conversion, such as MTHFR.

Vitamin B-Complex features L-methylfolate alongside methylcobalamin B12. Other supplements, like Intrinsi B12-Folate™, also feature both nutrients in activated forms with added intrinsic factor for enhanced absorption.
