PURE is committed to providing premium-quality products based on the best of science and nature. This philosophy includes the avoidance of artificial dyes, colors, flavors, sweeteners and other potentially harmful ingredients. Ingredients PURE selects for inclusion are natural, derived from natural sources, or made through natural processes. Our preference is to select natural ingredients as much as we can; however, certain ingredients do not have a natural source necessary to adequately support what the body needs.
