Nervous System Health B-Complex for Maximum Effectiveness Supports Energy Production Non-GMO A Dietary Supplement Vegetarian/Vegan Kosher Vitamins Family Owned Since 1968 GMP Quality Assured B-100 Caps provide 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.
