As used herein, “arginine' is intended to mean nutritional use that can replace arginine alone. One useful L-arginine (Arg), a naturally occurring amino acid, with or material is arginine silicate inositol (ASI) complex. without a salt counterion, available in purified form from 0008. Therefore, if certain nutritional products containing Glanbia Nutritionals, Inc. (Carlsbad, Calif.). ASI were able to promote wound healing, this would repre 0018. It has now unexpectedly been found that arginine sent a contribution to the medical and nutritional arts. silicate inositol (ASI) complex may be used to make an edible US 2016/008 1959 A1 Mar. 24, 2016 nutritional composition that is effective for treating wounds, increased bioavailability of the arginine coming from the ASI. i.e., useful for wound healing or repair. It is believed that In addition, arginine is known to have a very unpleasant taste ASI-containing compositions are useful for treating wounds which makes it relatively unpalatable, especially for patients including, but not limited to, cuts, scrapes, scratches, burns, coming off of Surgery who may be suffering from nausea or electrical wounds, bites, stings, incisions, amputations, anal who have other wound healing needs. The smaller dose of fissures, punctured skin, and the like. ASI compared to other forms of arginine may help make a 0019. In addition, the arginine and silica from ASI are product more palatable or may be easier to mask flavor-wise. highly bioavailable meaning that less is needed to provide a 0025 Silicate is also a component of ASI and may also similar effect seen from other arginine sources.
