L-Arginine supplement

May you take L-arginine every day?

It is generally considered safe to take L-arginine supplements daily. However, because it may interact with certain medications and affect some medical conditions, we recommend that you first consult with your doctor about its use in those situations.

When is the best time to take arginine?

When taken on an empty stomach, the supplement is optimally absorbed by the body. However, if that leads to nausea, then it is best to take L-arginine shortly before or after a meal.

What foods are high in L-arginine?

Foods high in L-arginine are: nuts, seeds, tofu, soybeans, chicken and turkey. Eating dairy products and legumes can also increase L-arginine levels in the body.

What are the side effects?

The most common side effects of L-arginine are nausea, abdominal pain and diarrhea. If you are taking medications for hypertension, consult with your doctor first.

Who should not use arginine?

People with certain medical conditions, such as kidney or liver disease, should avoid taking L-arginine supplements. In addition, pregnant and lactating women should not use L-arginine because there have not been enough studies to determine its safety.
