Natural collagen
Like every other protein, collagen consists of amino acids. According to studies, the major amino acids in collagen are proline, glycine, and hydroxyproline. Amino acids have similar structures to chains. The amino acids in the protein are twisted around each other like a rope. This contributes to the strength and stability of collagen. The protein is naturally synthesized in the body by cells known as fibroblasts.
To boost the production of collagen in the body, you must consume an adequate amount of vitamin C [1] and protein [2]. Several meals and supplements can also increase the collagen levels in the body.
