Formulation Notes

This product provides a full complement of B-vitamins plus choline and inositol. These vitamins work to support energy production, maintain healthy homocysteine metabolism, and promote the health of the nervous system. B-vitamins are water soluble, and with the exception of B-12, have limited storage in the body and thus require daily replenishment.

While B-12 is stored in the liver, dietary sources are of animal origin only (meat and dairy) and supplementation with B-12 may be especially important for vegetarians.

Natural color variation may occur in this product.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.
