Endurance Amino compares extremely well to high priced amino acid tablets on the market, at a fraction of the cost. The foundation of Endurance Amino is the three Branched Chain Amino Acids, or BCAA (l-leucine, l-isoleucine, l-valine), supplementation of which helps delay exercise-induced or central nervous system-induced fatigue, improve immune system reaction, and enhance recovery. Another amino acid, l-alanine, is included in the Endurance Amino formula. The liver can convert l-alanine into glucose as needed, which the bloodstream transports to the muscles for energy. Additionally, l-alanine aids in the synthesis of pantothenic acid (Vitamin B5), which is also needed for protein, fat, and carbohydrate metabolism.
For years, the American Red Cross used ALT testing as part of the battery of tests to ensure the safety of its blood supply by deferring donors with elevated ALT levels. The intent was to identify donors potentially infected with hepatitis C because no specific test for that disease was available at the time. Prior to July 1992, widespread blood donation testing in the USA for hepatitis C was not carried out by major blood banks. With the introduction of second-generation ELISA antibody tests for hepatitis C , the Red Cross changed the ALT policy. As of July 2003 [update] , donors previously disqualified for elevated ALT levels and no other reason may be reinstated as donors by contacting the donor-counseling department of their regional Red Cross organization.
