The purpose of this study is to test whether a natural product supplement can potentiate the increase in collagen synthesis following the ingestion of collagen protein. The investigators have developed a model of natural (GRAS certified) products that stimulate collagen synthesis, in vitro. The investigators will determine whether the natural product supplement can potentiate the collagen synthetic response to the ingestion of collagen protein. Basal and fed serum will be isolated and these samples will be used to treat human engineered ligaments.
