Formulation Notes

Each required nutrient in the Vitamin B Complex performs a unique role in maintaining proper metabolic functioning, while nutritionally supporting the body during the occasional stress of daily living.

B Complex vitamins are needed for the metabolism of carbohydrates, fats and proteins, which convert food into energy. In addition, these vitamins play a necessary role in supporting cardiovascular health, the promotion of a healthy nervous system, and support for red blood cell formation.
