L-Arginine is a conditionally essential Amino Acid that can be obtained via the diet. In some situations, the body’s requirement for Arginine can be greater than production (conditionally essential). You may have noticed that Arginine has become a staple ingredient within pretty much every pre-workout supplement on the market, and is commonly found in daily foods such as chicken, beef and soya. L-Arginine would be a suitable ingredient to use as part of a pre-workout, perhaps combined with Caffeine, Beta Alanine, Citrulline Malate and Branched Chain Amino Acids.
