Amino acids and their significance for virility and libido
The future is bright concerning the topic of protein/amino acid nutrition in health and disease, and particular promising directions—such as inter-organ amino acid nutrition, tissue/niche heterogeneity of amino acid metabolism, and the role of the microbiome and epigenome in the interaction of amino acid supply/metabolism with various traits such as immunity—should be considered for future study. Indeed, with the advent and application of new technologies and ‘big data’, many new interesting and pivotal interactions will undoubtedly be uncovered.
Important for men’s health an amino acid normally made by the body. The body converts L-citrulline to L-arginine, another type of amino acid. L-arginine improves blood flow. It does so by creating nitric oxide (NO), a gas that helps dilate blood vessels. Some amino acids are the building blocks of protein. In your body, it turns into nitric oxide. In one study, about one-third of men who took 5 grams of it per day for 6 weeks had improved erections.
L–citrulline is mainly produced by fermentation of L‐arginine as the substrate with special microorganisms such as the L‐arginine auxotrophs arthrobacterpa rafneus and Bacillus subtilis.. Used in pharmacy compounding in the United States in a wide range. The U.S. Food and Drug Administration (FDA) does not regulate L–citrulline as a drug.
