L-arginine is a semi-essential amino acid that plays a crucial role in various bodily functions. While our bodies can produce it, obtaining it through diet is also important. So, What Food Has L Arginine? Let’s explore the best dietary sources and the benefits this amino acid offers.
Understanding L-Arginine
L-arginine is involved in protein synthesis, wound healing, immune function, and hormone secretion. It’s also a precursor to nitric oxide, which helps blood vessels relax and improves circulation. Because of these functions, sufficient L-arginine intake is important for overall health.
