Our Collagen Granules and Powder both contain at least 90% protein and the same amino acid makeup. They therefore achieve the same thing in the body. The difference is simply a preference. The Granulated nature of the Granules means that this product dissolves effortlessly into liquids such as tea, coffee or even juice. The Powder is much finer and takes some agitation to dissolve. The Granules are our premium product simply because of how easy they are to use! But whichever one you choose, your body will thank you.
