Amino Acids and Peptides: Amenable Amino Acids and Peptides
For example, branched chain amino acids (L-leucine,
L-isoleucine and L-valine) are found in products targeting body builders. Two approaches to incorporating these components exemplify the primary options in formulating with many “nutraceuticals.”
In the first case, the desired component itself can be added to a product. Solgar Vitamin and Herb, Leonia, N.J., recently introduced Whey To Go protein powder and notes that it contains free-forms of these amino acids. Similarly, the ingredient list of Life Services Supplements', Neptune, N.J., Muscle Research Labs branded Createc DS-3 separately identifies these components. NOW Foods, Bloomingdale, Ill., takes a second approach by formulating with less refined ingredients that contain the desired compounds. Its Lean Grow protein powder uses protein from “microfiltered whey concentrate, soy isolate, egg white, and milk casein.” These proteins, in turn, provide a “typical amino acid profile” with 1,556mg L-isoleucine, 3,860mg L-leucine and 1,742mg L-valine.
