A deficiency occurs when your body does not absorb enough L-arginine or does not produce it itself.
Too much stress, high performance requirements, gaining social recognition and high pressure then lead to a lack of protein building blocks.
L-arginin, as a basic amino acid, is one of the basic building blocks of your body. Even muscles and bones need protein to build and maintain them.
