The Active Ingredient Is: Vitamin B12 (Cyanocobalamin)

Vitamin B12 is a water-soluble vitamin essential for normal nervous system function and red blood cell formation. This formulation provides a sustained-release supply of the vitamin to support steady availability throughout the day.

Vitamin B12 is provided in a sustained-release tablet by cyanocobalamin, a form commonly used in supplements for stability and reliable absorption. This formula also contains other B vitamins and related nutrients that support energy metabolism and overall B‑complex function.

What Does Vitamin B12 Do?

Vitamin B12 participates in energy production processes and helps support neurological function as part of the body’s normal metabolism. It also contributes to red blood cell formation, which is important for carrying oxygen to tissues to maintain vitality.

In the context of a B-complex product, this vitamin works alongside other B vitamins to support healthy energy metabolism and nervous system activity.
