Applied Nutrition L-Arginine Plant-Based is crafted with plant-derived ingredients like arginine, citrulline, and beta-alanine to boost energy levels. This supplement contains amino acids and proteins that help dilate blood vessels, enhance blood flow, increase oxygen delivery to muscles, and stimulate muscle tone. It also promotes the secretion of growth hormone and insulin to improve blood flow. L-Citrulline, an amino acid, enhances the body’s ability to produce certain proteins and provides extra energy to boost performance. Beta-alanine, on the other hand, improves endurance, ability, and overall performance.
