Main highlights
✓ NATURAL WELLNESS - We believe that cleaner is better, we craft our vitamins and minerals in small batches to help ensure consistency and purity from bottle to bottle
✓ IDEAL FOR ATHLETES - Arginine is a non-essential amino acid, and although it can be created by the body, some groups of people can benefit from an increased intake. It is popular with athletes because of its essential role in muscle metabolism, helping the transport, storage and excretion of nitrogen. It also assists with generation and regeneration of tissue and is highly concentrated in the skin and connective tissues
✓ GOLD STANDARD - All Solgar products meet our industry recognized “Gold Standard” for excellence, made using naturally sourced ingredients and innovating since 1970
✓ COMMITTED TO SUSTAINABILITY - For over 70 years we've used 100% recyclable amber glass bottles. We believe that cleaner is better, we craft our vitamins and minerals in small batches to help ensure consistency and purity from bottle to bottle
✓ AMINO ACID - L-Arginine 1000 mg contains Arginine, one of the twenty classic amino acids involved in various pathways throughout the body. Amino acids can be further used by the body to create hormones, enzymes, neurotransmitters, antibodies and nutrient carriers. A suboptimal intake of the essential amino acids increases the body's need for the non-essential amino acids either through diet or supplementation
