B-50, 250 Tablets (Now Foods)

This description has been derived from the manufacturer’s / distributor’s website.

B-50 Tabs 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.
