The Active Ingredient Is: Vitamin B12 (Methylcobalamin)

Vitamin B12 in its methylcobalamin form is a biologically active coenzyme form essential for normal cellular function. This nutrient supports methyl group transfers vital for DNA synthesis and neurotransmitter production.

This formula also includes methylfolate and pyridoxal-5-phosphate, which help support the primary role of B12 and assist with energy metabolism and neural function through their cooperative roles in metabolic processes.

What Does Vitamin B12 Do?

Vitamin B12 assists with energy production and is involved in neurotransmitter synthesis and red blood cell formation, contributing to normal brain and nerve function. It also plays a part in the recycling of homocysteine, a process linked to cardiovascular and neurological health.

In combination with methylfolate and B6, this active B vitamin supports overall metabolic function and mitochondrial energy pathways, aligned with standard nutrient function expectations.
