L-arginine is an amino acid involved in a number of processes in the body, primarily related to the cardiovascular system. Whilst it is not considered one of the essential amino acids, i.e. the group that our body cannot make itself, it is still a very important one. HealthPost carries several l-arginine products, both on their own and in combination with other amino acids.

L-Arginine Info

L-arginine is a non-essential amino acid used to form nitric oxide in the body, which in turns aids circulation, blood flow, and relaxes blood vessels. It is also heavily involved as an antioxidant, supporting healthy inflammatory processes and immune function, and is involved in the function of nerve cells and the nervous system. Our levels reduce as we age, and many people don’t get adequate levels from their diet.

L-arginine is also popular for those who participate in sports or intense exercise due to its participation in the synthesis of protein, it’s potential to be converted into glucose, and therefore be converted into energy. Arginine is also used to produce various compounds other than nitric oxide, including creatine and glutamate within the body.

Product Reviews

  • Not impressed


    I am taking this product to help reduce blood pressure; have been taking for a month now, one in the morning and one at night; and haven't noticed any different, my blood pressure hasn't changed either; will be going back to the solgar product at least they are in a capsule form and not a solid tablet that has a horrible taste to it.



  • Effective!


    Did a bit of research prior to using this product and have to say it delivers on the promise.
    Easy to take, found that it worked best for me by taking one before breakfast and one before dinner.



  • Not sure


    Have only taken half the tablets so far and have not noticed any difference. Properly a bit early to see expect any effects.
