There are various collagen supplements. Skin for Skin has developed a native collagen supplement, which gives you a dose of 200 mg of pure collagen and 20 mg of vitamin C. Through our natural, patented extraction process, we obtain native collagen instead of hydrolysate. The RDA of our pure native collagen cannot be compared with that of collagen hydrolysate. In addition, we have added vitamin C to our collagen supplement. Vitamin C helps your body to produce its own collagen in a natural way. In addition, you ingest a natural, pure form of collagen through our supplement. Collagen is a protein and consists of amino acids. These amino acids are building blocks. Our collagen does not have an aftertaste. Read more about our collagen supplements here.
