L-Arginine Health Benefits


L-Arginine Health Benefits

As mentioned above, L-arginine offers many health benefits. Here are some of them in no particular order.

It helps improve blood flow

Many people suffer from peripheral arterial disease, a disorder when blood vessels shrink and hinder blood flow to the limbs. Studies have shown that taking oral supplements regularly can improve blood circulation.

L-arginine increases Nitric Oxide and the NO’s release enlarges blood vessels enabling blood to flow freely.

When blood flows throughout the body without any hindrance, the body functions properly, and there is improvement in every sphere.

It helps to build muscles

L-arginine plays a role in building protein and releasing nitric acid, both necessary for muscle development. When you have a continuous supply of the amino acid and train regularly, there will be muscle gain and you can maintain the level.

It regulates blood pressure

Millions of people suffer from hypertension and high blood pressure and even lose their lives. Experiments conducted on volunteers showed that regular usage of L-arginine supplements lowered blood pressure and maintained the balance.

The experiments included both oral use and intravenous administration. The positive effects are because L-arginine helps widen the blood vessels, enabling free blood supply and circulation.

Pregnant women also suffer from high BP sometimes. L-arginine via IV can be beneficial and lower blood pressure. But patients must get treated only by healthcare professionals for this issue.

It maintains blood sugar levels

Diabetes is a cause of disease and death among millions of people worldwide. People suffer from it because of several reasons. It can be lifestyle, obesity, diet habits and heredity because diabetes is a hereditary ailment.

Studies have shown that taking L-arginine supplements boost glucose metabolism and insulin sensitivity. People who took L-arginine daily for eighteen months had less risk of developing diabetes than those in a placebo group.

Nitric Oxide improves cellular function, and since L-arginine releases nitric Oxide, it can help increase insulin and allow the body use blood sugar more efficiently.

It may improve physical performance

Some studies have also indicated that athletes who took L-arginine supplements for at least forty-five days showed improvements in their physical performance than those who took a placebo.

Those athletes in the former group also showed signs of increased blood flow, and they could train longer.

If you are planning to undergo intensive training to build muscles, L-arginine supplements may be beneficial.

It may lower the risk of angina

Angina is a condition that produces chest because blood cannot flow freely to the heart. It happens due to the contraction of blood vessels.

Experiments conducted on angina patients with L-arginine showed that symptoms lowered, and they could exercise longer than before. The quality of life also improved for those patients.

However, blood vessels didn’t seem to enlarge for those with the disease. Patients will therefore need other treatments to cure that. L-arginine may therefore be suitable for the prevention of narrowing blood vessels before angina sets on.

It may improve male sexual health

Many men have problems related to their sexual health. One of these is erectile dysfunction or ED. Having this problem can lower morale and confidence as they are unable to perform.

Men with erectile dysfunction (ED) who took a daily dose of 2.5-5 grams L-arginine orally seemed to show improvements. However, experts also suggest that taking it along with medication may be more beneficial than taking either one of them alone.

It may prevent Necrotizing Enterocolitis (NEC) 

NEC is a disease associated with premature infants that affect the intestines. It causes the intestinal tissue to inflame and die. The condition happens due to t several reasons, such as

  • Inadequate oxygen or blood flow to the intestines during or after birth
  • Injury to the intestinal lining
  • Excessive growth of bacteria in the intestine
  • Viral or bacterial infection in the intestine

Other possible L-arginine health benefits

Including L-arginine in their formula may lower the risk and prevent the condition. Healthcare professionals will add L-arginine to formula if a baby is at risk of being affected by the condition.

Other possible L-arginine health benefits

Though more studies need to be conducted, L-arginine may be beneficial in treating the following issues:

  • It may heal injuries faster
  • It may reduce anxiety and depression

  • It may heal burns

However, as mentioned, before using L-arginine for any of these issues, it is advisable to consult your doctor.
