Nutrition 21's patented ingredient combining amylopectin and chromium, branded Velositol, has attained GRAS (generally recognized as safe) status after an extensive and rigorous review of the scientific dossier and safety data conducted by Intertek Health Sciences, Inc. Velositol was determined to be GRAS at the recommended serving of 2 grams per day in protein drinks (including ready-to-drink and powder), meal replacement bars, energy and protein bars; with the consideration that these products can be taken up to three times a day.

Attaining GRAS status is an important and extensive process requiring third-party review of scientific and safety information. Although the U.S. Food and Drug Administration (FDA) doesn't approve foods prior to market, it does subject food additives to a pre-market review and approval process, unless the substance is generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use.

A recent study published in Journal of the International Society of Sports Nutrition shows Velositol doubles the rate of muscle protein synthesis (MPS) when combined with whey protein (6 grams); the rate of MPS increased by 48% from baseline as compared to a 24% increase from baseline seen with whey protein alone.

"We believe using Velositol is a more efficient way to build muscle and will really unlock the power of protein," said Joe Weiss, president of Nutrition 21. "Velositol was formulated to enhance the insulinogenic response, which increases amino acid uptake in muscles, and is protected under a number of patents and pending patent applications."

Research on Velositol shows a significant increase in MPS, along with a non-significant increase in insulin; a key factor to initiating muscle growth. Blood glucose levels remained in the healthy, normal range for study participants.
