Side effects LArginine

People that are thinking of using L-arginine as a food supplement often ask the question.

What are the side effects of L-arginine? 

This article will inform you of the L-arginine benefits and all the side effects of L-arginine, we will also look at the effectiveness of Nitric oxide supplements and their role in body building, enhancing erectile dysfunction ED and dissolving arterial plaque.

L-arginine or arginine is an important amino acid because of its impact on blood flow and a normal functioning healthy heart. L-arginine when mixed with l-citrulline has been helpful in reversing coronary artery disease  

In numerous studies and customer testimonials L-arginine has demonstrated its ability to reduce or reverse heart disease, lower high blood pressure, speed up the healing of wounds, L-arginine has also been proven to help with erectile dysfunction.

L-arginine or Arginine what is the difference?

​Very little in fact, both ingredients are commonly referred to in the same breath, L-arginine has some 20 components and is the L that is referred to in supplements. The benefits of taking L-arginine or arginine are the same.

L-arginine side effects

L-arginine has very few reported side effects, the side effects that we know about are:

  • Diarrhoea
  • Bloating
  • Skin rash
  • Itching
  • Hives
  • People with asthma had worsening allergies. ​


What’s in L-arginine?

​Essentially an amino acid is the building block for protein in our bodies, in a typically healthy person three quarters of our bodies are made up of joined amino acids involved in chemical messaging.

​ Larginine has been the subject of large-scale research as well as clinical trials. It is essential for our body’s well being, we can produce Larginine from the foods that we eat, however this can be affected by

  • ​The ageing processes
  • Stress
  • Not enough of the right arginine producing foods
  • Alcohol
  • Trauma

Not enough L-Arginine means poorer blood flow that over time can lead to:

  • Atherosclerosis
  • High Blood pressure
  • ​Heart disease
  • Blood clots
  • Diabetes
  • Stroke
  • Peripheral artery disease
  • Leg ulcers

​L-arginine supplements help our bodies to produce more L -arginine and keeps our bodies in a healthy state.

L-arginine or arginine encourages hormone production, insulin is a growth hormone and is the forerunner to nitric oxide.

Effects of Nitric Oxide Endothelium

The Endothelium

​The Endothelium are the cells that line the inner surface of our blood and lymphatic vessels, these cells produce nitric oxide gas, nitric oxide helps our blood and lymphatic vessels to stay smooth and relaxed making it easy for blood, nutrients and oxygen to flow to all parts of the body.

What are the main benefits of L-arginine?

​Blood circulation

​The biggest benefit of L-arginine is its ability to create nitric oxide allowing our blood vessels to stay relax, expand and stay smooth. More oxygen, glucose & nutrients are carried to the tissues in the body. The result of this is an improvement in peripheral circulation and at the same time providing support against commonplace vascular issues such as arterial plaque, narrowing of the blood vessels and high blood pressure.

Coronary artery disease.

​L-Arginine can assist with improving the function of blood vessels thus improving blood flow to the coronary arteries. Nitric oxide plays its part by making the coronary arteries more elasticated allowing better blood flow and inhibiting high blood pressure.

A note of warning, if you have had a heart attack please get good advice regarding large doses of L-arginine because too high a dose may have an adverse effect.

Erectile dysfunction

ED or Erectile dysfunction

​In one study the main cause of Ed or erectile dysfunction was a lack of enough blood flow to the penis, this can be corrected by taking a drug (Viagra) or food supplement that contains nitric oxide, the nitric oxide will help to dilate the blood vessels and improve the flow of blood to the genital area and the penis.

Women have found arginine to be supportive in increasing blood flow to the genital area leading to an increase in libido.

L-arginine and wound healing:

People that eat a diet with low amounts of arginine often find that a wound will take longer than normal to clear up or heal itself. The reason for this is a diminished amount of collagen content around the site of the wound-arginine encourages hormone production thus stimulating a metabolic path for the healing process-Arginine enhances blood flow to the wounded area and increases the amount of collagen so necessary for healing to take place.

L-arginine & body building

​Body builders use L-arginine because of its ability to improve the growth hormone in the body. It is needed for the fusion of proteins and promoting lean muscle mass, L-arginine is noted to help with circulation, so it enhances the endurance levels and condition of people who work out, it also helps with recovery times and muscle damage.

Which foods contain arginine?

​Arginine can be found in lots of protein rich foods such as:

  • Beef
  • Chicken
  • Pork
  • Tuna
  • Halibut
  • Salmon
  • Eggs
  • Yoghurt
  • Milk
  • Soya beans
  • Oats
  • Wheat
  • Pumpkin seeds

Recommended-arginine dosage

​There is no recommended RDA intake of l-arginine, having said that a lot depends on what condition you are trying to deal with. Generally, the average intake daily of l-arginine is somewhere in the region of 2-5 grams per day, this amount would normally be enough for protein synthesis and tissue repair.

Other factors

​Your age, family history, body condition, circulation level and inflammation level will determine how much L-arginine you should take each day. In my experience and after my heart attack I took 3 sachets of Proargi 9 +(almost 10 grams each) three times per day.

That equates to almost 30 grams per day, I know that sounds like a lot but believe me when I tell you IT WORKED!

As our bodies age we find it harder to absorb the vital amino acids from the foods that we eat leading to a deficiency in nitric oxide, so we need to take a food supplement that will help to restore the nitric oxide deficiency.

Is L-arginine safe to take?

Providing you stick to the recommended dose, if you are over 50 and have heart disease, diabetes, bad circulation or poor wound healing a good daily therapeutic range would be between 4- 30 grams daily. Start off slowly no more than 10 grams, if you don’t have too many side affects you can gradually increase up to 30 grams per day.

L-arginine drug interactions

​Please see your doctor if taking blood thinners like warfarin or aspirin, if taking a supplement like gingko biloba it is advisable to check with your doctor first in case of excessive bleeding.

Pregnant women have reported it to be safe to take, after all it is essential for human growth and development but check with your first.

Arginine rich foods can trigger conditions such as herpes or shingles, so it is best to take doctors’ advice on this issue.
