An arginine supplement supplies L-arginine, an amino acid the body uses to make nitric oxide. Nitric oxide helps relax blood vessels, but supplement effects vary by person and purpose; it is not a treatment for disease.
An arginine supplement may help some people with erectile dysfunction related to blood flow, but research is limited and results are inconsistent. It does not address every cause, so it should not replace medical evaluation or prescribed treatment.
An arginine supplement is often taken before exercise in hopes of improving blood flow or performance, but study results are mixed. It is not a reliable substitute for training, adequate food, or rest, and some users experience stomach discomfort.
There is no single dose that suits everyone; amounts depend on the product and reason for use. Follow the product directions rather than treating a typical serving as a recommended dose, and do not take more to try to speed up results.
An arginine supplement can cause nausea, abdominal pain, bloating, or diarrhea, and it may lower blood pressure. Stop taking it if symptoms develop; seek medical attention for severe or persistent symptoms.
Yes, an arginine supplement may lower blood pressure by supporting nitric oxide production and blood-vessel relaxation. This can be a concern if you already have low blood pressure or take blood-pressure medication.
An arginine supplement can be taken daily according to its directions, but daily use is not necessary or suitable for everyone. Evidence for long-term benefits is limited, and ongoing use may increase the chance of side effects.
Yes, an arginine supplement may interact with blood-pressure drugs, nitrates, and erectile dysfunction medicines such as sildenafil, potentially lowering blood pressure too much. Ask your doctor or pharmacist before using it if you take medication or have cardiovascular disease.
No, there is no reliable evidence that an arginine supplement raises testosterone. Arginine is involved in nitric oxide production, but that role does not establish a testosterone-boosting effect.
It may trigger cold sores in some people because arginine can support the replication of the virus that causes them. If you get recurrent cold sores, consider this risk before taking an arginine supplement and stop if outbreaks worsen.

An arginine supplement provides arginine, an amino acid used in protein synthesis. It is commonly sold as a powder or in capsules; powder can be mixed into water or another drink. Arginine also serves as a precursor to nitric oxide in the body.
The taste varies by product, though plain powder can be slightly bitter in water. Follow the serving directions on the label; the typical serving listed here is about 5 g. Nutritionally, it is concentrated protein, with no carbohydrate or fat listed. If you follow a vegan diet or are considering adding it to your routine, check the product’s ingredients and directions to make sure it suits your needs.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
