Simply Supplements are delighted to offer this exclusive combination of the B-group vitamins formulated by Simply Supplements nutritionists to provide 100% RDA of each. Each B Vitamin tablet is believed to support the maintenance of overall health, including neurological and cardiac function. Our unique Vitamin B Complex includes Thiamin (B1) which is thought to play a role in the normal metabolism of carbohydrates as well as normal neurological and cardiac function. Riboflavin (B2) and Niacin (B3) are also believed to contribute to the normal release of energy from food. Since all B vitamins (except B12) are water-soluble and therefore cannot be stored by the body, a regular daily intake of these essential vitamins through the diet is necessary if we are to benefit from their health-related properties.
