The Main Benefit Is: Energy Metabolism Support

The main benefit relies on energy metabolism support provided by a high-potency B-complex. This group of nutrients functions as cofactors in converting food into energy and supports nervous system health through everyday metabolic function. The formulation includes a broad range of B vitamins and related nutrients that together support metabolic processes essential for daily energy production.

This formula also includes extra components such as choline and inositol, which contribute to wider metabolic activity and normal cellular function, all sourced from vegetarian-friendly ingredients and produced to strict quality standards.

What Does Energy Metabolism Support Do?

Energy metabolism support contributes to everyday energy production and nervous system function, in line with EFSA guidance. It plays a role in turning nutrients into cellular energy and supports neurotransmitter synthesis, contributing to everyday physiological function.

Dr. Kennedy at University found that B-vitamin supplementation can support energy and cognitive function in healthy individuals.
