Purely-B is the only whole food B complex concentrate available. Unlike other B vitamin supplements, the nutrients in Purely-B are 100% natural - no synthetics are added. Nor is this corrupted by feeding synthetic vitamins to yeast, as is done with imitation whole food supplements. Purely-B is a real food source of amino acids, niacin, thiamine, riboflavin, pyridoxine, iron, magnesium, and phosphorus. It also contains pure essential fatty acids and easy-to-digest, nourishing carbohydrates. Plus it is fortified with wild, raw chaga and organic maca, which give it a rich, mocha-like flavor. Chaga and maca are dense sources of B vitamins and minerals. This is the natural way to energize the body.
