Arginine is a semi-essential amino acid, meaning the body can produce it in limited amounts, but it may need to be obtained from diet or supplements, especially during physical stress or illness. It plays a role in various biological processes, including protein synthesis, nitric oxide (NO) production, and ammonia detoxification.
Arginine is used as a dietary supplement to support cardiovascular health, as nitric oxide produced from arginine helps relax blood vessels, improving circulation and lowering blood pressure. It is also used to promote wound healing, support immune function, and enhance physical performance.
It is naturally found in foods such as meat, fish, eggs, dairy, nuts, seeds, and legumes. As a supplement, it is available in capsule, tablet, or powder form.
Side effects are rare but may include nausea, abdominal cramps, or diarrhea, especially at high doses. People with conditions such as herpes (herpes simplex virus) should avoid arginine supplements, as it may promote viral replication. Additionally, individuals with cardiovascular diseases or other health conditions should consult a doctor before using arginine as a supplement.
