As one of the best healing compounds for workouts, L-arginine is an excellent supplement. How long does it take for l-arginine to work? We have the answer.

What is L-arginine?

L-arginine is one of 20 essential amino acids. Each amino acid works differently in the body.

The body can’t synthesize some amino acids, so they must come from diets. Others can be synthesized without the need to add them to your diet.

L-arginine is considered conditionally essential, which means the body can generally synthesize it except for certain special conditions.

In the case of the latter, it would be optimal to supplement it. Even if your body makes it naturally, an extra boost in l-arginine is great when it comes to workouts.

If you have coronary artery disease, chest pains, blocked arteries, high blood pressure, or other heart and blood vessel conditions, L-arginine supplements could be helpful.

How Much L arginine Should I Take Daily?

There is no specific dosage that works for everybody. In determining how much l-arginine to take daily, follow the recommendations given by the product you’re using and start from there.

According to some studies, anywhere between 5 and 16 grams a day should be safe from adverse side effects.

However, if you feel you need to take more L-arginine, gradually increase the amount.

Taking too much of a nonessential amino acid can be harmful, so always consult a physician if you plan to go beyond the recommended dosage.
