L-Arginine
L-Arginine is an amino acid that helps the body produce proteins, which are essential because every cell in the body contains proteins. It is also available as a supplement and has been studied for its potential benefits on various conditions, including obesity, heart disease, cancer, polycystic ovary syndrome (PCOS), infertility, anxiety, chest pain (angina), and erectile dysfunction. However, results are mixed, and L-arginine may not be as effective for some conditions as many supplement companies claim.
Benefits of L-Arginine:
- Supports heart health: L-arginine can help reduce blood pressure and lower blood sugar levels.
- Reduces chest pain: L-arginine can help reduce symptoms and improve exercise tolerance in people with angina.
- Improves erectile dysfunction: A 2019 review of 10 studies found that taking arginine supplements in doses ranging from 1.5–5 grams daily significantly improved erectile dysfunction.
- Helps build muscles: L-arginine helps the body build protein, which can help repair wounds and build muscles.
Dosage:
The appropriate dosage of L-arginine depends on several factors, including age, health status, and the condition being treated. A 2018 study determined that a dosage of up to 30 grams per day of L-arginine is safe in most adults.
Potential side effects:
L-arginine is generally considered safe when used in moderate doses. However, some people may experience side effects such as bloating, diarrhea, dizziness, nausea or vomiting. Life-threatening side effects are rare but possible. L-arginine interacts with other medicines, so it’s important to talk to a healthcare provider before taking it if you’re currently taking any medications. Pregnant or breastfeeding women should avoid taking L-arginine supplements without first consulting their healthcare provider.
Case studies:
- A 2019 review of 10 studies found that taking arginine supplements in doses ranging from 1.5–5 grams daily significantly improved erectile dysfunction.
- In a study conducted by Martina et al., L-arginine supplementation of 2.1 g per day in combination with N-acetylcysteine at a dose of 2.1 g per day for 6 months helped reduce cardiovascular risk factors in healthy men.
