## Description

NUTRABIO L-LEUCINE FREE FORM AMINO ACID SUPPLEMENT HPLC LAB TESTED FOR POTENCY Leucine is thought to be the most effective BCAA for preventing the body's burning of muscle stores for energy during intense workouts because it is converted to glucose more quickly than isoleucine and valine. L-Leucine is an essential amino acid, meaning it cannot be made by the body, and must be acquired through food or dietary supplements. Leucine is classified as a branched-chain amino acid (BCAA). It comprises about 8% of the total amino acid count in your body's protein structures and is the fourth most concentrated amino acid in skeletal muscle tissue. L-Leucine stimulates muscle protein synthesis and may be the major fuel involved in anabolic (tissue building) reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength. ABOUT NUTRABIO: NutraBio Labs has a "No Compromise" commitment to producing the purest, cleanest, and most effective supplements on the market. All of our products are manufactured in-house in our FDA-inspected, GMP certified facility in New Jersey. NutraBio only uses the most superior ingredients and all ingredients are tested by us and a third party lab to ensure 99.98% purity or greater.
