While most amino acid powder products are produced by hydrolyzed process using duck feathers or human hairs, Micro Ingredients(TM) Natural Amino Acid products are made from an environmentally clean and natural fermentation process using plants and vegan base materials, free of harsh chemicals. L-Arginine is a basic natural amino acid produced by consuming a protein rich diet and is necessary for the body to maintain those proteins. L-Arginine is known for maintaining skin, joints, liver, immune system and muscle strength. It is also used to maintain heart and blood vessel conditions. First isolated from a lupine seedling and characterized in 1886, L-arginine is one of the twenty typical a-amino acids used as building blocks for protein. As such, it is present in a wide variety of foods of both plant and animal origin with particularly high levels found in eggs, almonds, spinach, and lobster. L-arginine is considered to be conditionally essential; meaning for the average adult adequate levels of arginine can be obtained from the diet or through biosynthesis/recycling. However during growth and at other times when nitrogen balance is altered, such as when the body is healing, diet, and biosynthesis; adults may not meet the needs of arginine for the rate of biosynthesis does not atone for the depletion or the lack of supply. Arginine is important in several pathways, including the synthesis of protein, creation of creatine phosphate which is need to produce ATP, and also the production of the second messenger involved in blood flow, nitric oxide. Other benefits that arginine is believed to assist with is boost athletic performance, lower high blood pressure naturally, boost the immune system, and assist in weight loss by increasing muscle to fat ratio.
