L-Arginine 1000 mg, Solgar tablets. Amino acids are the fundamental building blocks of proteins and support a wide range of bodily functions. They are categorized as essential and non-essential. Essential amino acids cannot be produced by the body and must be obtained from the diet. Beyond their role in protein synthesis, amino acids are used to manufacture hormones, enzymes, neurotransmitters, antibodies, and nutrient transporters. When intake of essential amino acids is insufficient, the body's need for non-essential amino acids rises, requiring dietary sources. Foods that help boost amino acid intake include meat, beans, cheese, and eggs. Arginine is a non-essential amino acid; although the body can synthesize it, certain groups may benefit from an extra supply. It participates in muscle metabolism. This product provides the amino acid in its free form to promote absorption. Suitable for vegans, vegetarians, and those following kosher guidelines. It contains no added sugars, salt, or starch.
