The Active Ingredient Is: Vitamin B12 (Cobalamin)

Vitamin B12 is a water-soluble vitamin that helps with normal nervous system function and energy metabolism. This formulation delivers B12 in a coenzyme B12 form to support quick metabolic readiness when absorbed under the tongue.

This formula also contains other B vitamins and Coenzyme Q10, which help to support energy metabolism and nervous system function.

What Does Vitamin B12 Do?

Vitamin B12 participates in cellular energy production and sustains neurological function, with supporting evidence from EFSA-style guidance on B-vitamin roles in metabolism and nerve health. Dr. Ramasamy of University demonstrated that B vitamins act as essential cofactors in these processes.

Additionally, B12 supports normal blood system function and neurotransmitter synthesis, matching the high-level nutritional understanding of B-complex roles in metabolism and brain health.
