Arginine

Meaning

Arginine, or L-Arginine, is a conditionally essential amino acid that plays a pivotal role in human physiology, particularly within the urea cycle and in the production of nitric oxide. It is a fundamental building block for proteins and is involved in numerous metabolic processes, supporting immune function and wound healing. In the context of hormonal health, its role as a precursor for key signaling molecules makes it significant for cardiovascular and circulatory function.
