Analysis

These B-100 tablets are a solid choice if you prefer the stability of a tablet over a capsule. They provide a high 100mg dose of essential B vitamins to support your nervous system and daily stamina. The formula also features a tiny amount of herbal powders like alfalfa and watercress, which add a touch of whole-food nutrients to the mix.
