Fuel yourself with NOW Foods - Vitamin B-50mg Veg Capsules, supporting energy production and nervous system health with B Vitamins, choline, and inositol. Working in complement with B vitamins, choline and inositol come together to support energy production within the body, maintain homocysteine metabolism, and protect the health of the nervous system. Most B vitamins require daily supplementation, as storage is limited sans Vitamin B-12, which is stored in the liver and must be replenished through dietary sources of meat or dairy, meaning supplementation is beneficial for vegetarians.
