We recommend following usage statements listed on the PURE product labels. If a product can be used by children, this information including how much should be used is available within the recommended usage statement. Products, which can be used by children include Mila, Probiotic, GPS Hydrate, GPS Energize, Daily Build, and GoYin. The product usage statements will also include restrictions of their use, if suggested. Another good general rule is whether or not the product uses a Nutrition Facts label or a Supplement Facts label. Products with a Nutrition Facts are foods and are generally safe for usage among children age 4 years and older. Foods include ingredients, which are categorized as generally recognized as being safe (GRAS). These products include Mila, and 360 Complete shakes.
