As well as improving ammonia recycling and nitric oxide metabolism, citrulline increases plasma levels of ornithine and arginine. Therefore, citrulline can be beneficial in situations where nitric oxide plays a key role, such as athletic performance, vascular health, and erectile dysfunction. \u003csup\u003e+[\u003ca href=\"https:\/\/examine.com\/supplements\/arginine\/\"\u003e1\u003c\/a\u003e,\u003ca href=\"https:\/\/examine.com\/supplements\/ornithine\/\"\u003e2\u003c\/a\u003e,\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17347276\/\"\u003e3\u003c\/a\u003e]\u003c\/sup\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eBeta-Alanine\u003c\/strong\u003e - \u003c\/span\u003eThe amino acid beta-alanine is not proteinogenic (i.e., it is not included in proteins during translation). As beta-alanine is synthesized in the liver, it is ingested in the diet through animal-based foods such as beef and chicken or through supplements. The beta-alanine ingested in the muscle and other organs forms carnosine. Beta-alanine is the limiting factor in muscle carnosine synthesis. During high-intensity exercise, beta-alanine enhances muscular endurance. \u003csup\u003e+[\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/27797728\/\"\u003e4\u003c\/a\u003e,\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24137022\/\"\u003e5\u003c\/a\u003e,\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11985892\/\"\u003e6\u003c\/a\u003e]\u003c\/sup\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eAgamatine Sulfate\u003c\/strong\u003e - \u003c\/span\u003eThe neurotransmitter and neuromodulator, agmatine, is derived from L-arginine through decarboxylation (removal of a carboxylic acid group). There are several mechanisms by which Agmatine works. It inhibits NMDA receptors, nicotinic acetylcholine receptors, and imidazoline receptors. Additionally, arginine inhibits nitric oxide synthase enzymes, which allows it to regulate elevated nitric oxide levels. It also inhibits calcium channels and certain serotonin receptors. \u003csup\u003e+[\u003ca href=\"https:\/\/link.springer.com\/article\/10.1007\/s002170050440\"\u003e7\u003c\/a\u003e,\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/8584654\/\"\u003e8\u003c\/a\u003e,\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22212617\/\"\u003e9\u003c\/a\u003e]\u003c\/sup\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eArginine Nitrate\u003c\/strong\u003e - \u003c\/span\u003eL-arginine is an amino acid naturally found in red meat, poultry, fish, and dairy.

Generally, it seems to reduce fatigue with continued muscle contractions and may therefore prove most beneficial during anaerobic cardiovascular exercise or muscular endurance events (like weight lifting, bodybuilding, hockey, rugby, and crossfit amongst other things).
