The chief content of this product is Collagen, which is 100% protein. As a protein Collagen primarily has three amino-acids- glycine, proline, and hydroxyproline. These aide in the health of connective tissue, skin, hair and nails. Each amino acid has a specific function in our body. Other protein supplements like whey can be consumed for muscle recovery and building muscle strength. Hence even if you are on a protein supplement, you can still take collagen along with that.
