Arginine is a natural amino acid with dozens of health benefits and it is found in many whole foods as well as several popular supplements. The side effects of taking arginine are minimal to none because of the fact that it is a natural amino acid. Any reported side effects have been minimal, but the health benefits are many including an improved blood pressure, reducing the chance of blood coagulation, improving symptoms of angina, reducing pain in extremities that can result from a lack of circulation, and other circulatory system improvements.

Arginine Health Benefits and Side Effects

Arginine supports healthy blood flow

The main health benefit of arginine is its ability to support healthy blood flow throughout the body. It does this by naturally widening the blood vessels and stimulating the body to produce nitric oxide. Nitric oxide relaxes the blood vessels and allows blood to flow through them more freely, and it helps the circulatory system pump blood to every part of the body. If you have normal blood pressure, arginine can help you maintain it and protect your health, and if you have high blood pressure arginine can lower it.


It can lower high blood pressure

People who have hypertension (high blood pressure) often have to take medications in order to control it. Arginine is a natural amino acid that can have a similar effect as blood pressure lowering medications without the same side effects. You should never replace your blood pressure medication with supplements without consulting a medical provider, but you may be able to supplement partially or completely with arginine after you are given a clearance from your doctor if you already have high blood pressure. Combined with exercise and other forms of stress control it can be highly effective.


Minimal side effects

There are minimal side effects that have been reported by a small number of people who use arginine. The side effects can include bloating and indigestion. It can also interact with certain medications like Viagra and blood pressure lowering medications, so if you are considering taking arginine and you already take medications be sure to get a clearance from your medical provider.
