The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12, namely the methylcobalamin version, is a water-soluble vitamin essential for normal metabolism and nerve function.

This blend uses activated B vitamins, including methylcobalamin, which are more readily used by the body to support its natural functions. This product also contains other activated B vitamins to support overall B vitamin action.

What Does Vitamin B12 Do?

Vitamin B12 plays a role in normal nervous system function and support for energy metabolism as part of standard dietary reference values.

Studies suggest that activated B vitamins may be linked to mood and cognitive support in some groups, and they help keep homocysteine levels within EFSA guidelines.
