Is L-arginine safe?

Is L-arginine safe? 

For those looking for the fountain of youth, you might turn to L-arginine supplements.  L-arginine is an amino acid that helps build protein in the body. One of the effects of L-arginine's protein-building quality is that it's converted into nitric oxide (NO). When this happens, NO improves blood flow, circulation, and lowers inflammation.  All of which have anti-aging benefits. Research shows you can't stop aging altogether, but you can slow down or treat age-related health concerns like heart disease, high blood pressure, arterial disease, and erectile dysfunction with L-arginine supplementation.


But is L-arginine safe?

For the most part, L-arginine is safe to use and available without a prescription.  When taking L-arginine supplements, whether it’s orally or topically, you should follow the package instructions and dosages.  If consumed appropriately there are few side effects. However, like any medication or supplement, there is a chance of adverse reactions.


Possible Side Effects Include:

  •      Diarrhea
  •      Low blood pressure
  •      Stomach pains
  •      Bloating
  •      Allergies
  •      Blood abnormalities

Doctors recommend limited use during pregnancy or while breastfeeding. Although there’s some evidence that shows L-arginine helps preeclampsia and prevents prematurity. Also, those on blood pressure medications or about to have surgery should receive medical advice before taking L-arginine. Dosage amount varies depending on body composition and medical condition.


Possible L-Arginine Anti-Aging Benefits


Improves Immune System

L-arginine plays a vital role in the regulation of immune function and inflammation. Some evidence suggests that increased levels of the amino acid help people fight disease.

Faster Recovery and Healing

Whether you want to increase exercise performance or recover faster from an injury, some research shows that L-arginine boosts nitric oxide production leading to quicker wound healing and recovery.


Improves Heart Health

One of the L-arginine benefits is improved heart health.  Scientific research shows that potential benefits include:

  • Reduces high blood pressure
  • Prevents congestive heart failure
  • Prevents kidney disease
  • Improved kidney function
  • Helps prevent heart attacks and heart failure


Improves Erectile Dysfunction

Being worried about sexual health hurts relationships. L-arginine converts into nitric oxide, which dilates blood vessels, leading to stronger erections and more sexual desire. Studies show that men improved erectile dysfunction by over 92% after three months of supplementation.


Encourages Weight Loss

Losing weight is a top priority for many people. Proteins from red meat, dairy products, poultry, and fish oil help increase muscle and decrease fat. And since L-arginine builds protein in the body, it may help people lose weight as well.


How to Increase L-arginine levels?

The two most popular ways to increase L-arginine levels is through diet and supplementation. When looking to add the amino acid into your daily intake, try the following foods:

  1. Turkey
  2. Pork loin
  3. Chicken
  4. Pumpkin seeds
  5. Peanuts
  6. Soybeans
  7. Dairy
  8. Chickpeas

But if worrying about your diet takes too much time or energy than an L-arginine dietary supplement is an answer. L-arginine supplements come in capsules, creams, tinctures, and shots.

Regardless of how you increase your L-arginine levels, the essential amino acid is overall safe and effective to use for both men and women. Start to feel younger today with a little more L-arginine in your diet.
