Supplements must be absorbed by the body and used in order for them to be beneficial. Dr. Price’s powdered vitamins don’t contain unnecessary fillers and additives like most pills, tablets and capsules. Therefore, your body doesn’t have to work as hard to break them down and benefit from their use. As you age, your digestive system can become weaker which makes it tougher to digest and absorb supplements. Our powders are not only made with the highest quality of ingredients but are formulated to be water-soluble. For this reason, when they are mixed with water they combine to become far more "Bio-Available". This results in a much easier digestive process and a far greater absorption.
