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

  • Brilliant product


    I am 74yrs old and have been diagnosed with hardening and narrowing of the arteries in my legs which cannot be treated with stents etc.
    I have horrendous pain in my legs and cannot walk very far.
    This supplement is absolutely brilliant. It softens and relaxes the arteries thereby increasing the blood circulation. The pain is reduced by at least 50% if not more and I can walk much longer distances without having to stop all the time and rest. At rest, when I also still had pain, the pain is now minimal.
    Thank you HealthPost please keep this product in stock. I will be ordering it regularly. It is certainly giving me a quality of life back !!



  • Disappointed


    Not the best for Male functions .



  • 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.
