My sister has got some health problems, MS, and it was recommended to take l-arginine. Tablets were of normal size, she took them normally.

protein

It is said to help in protein building and hence circulation. Previously I bought this with ALA to help with nerve issues, circulation and therefore nerve heath. Since I am going in a different direction now for the rehab I have finished one bottle and perhaps that will give the initial boost which is needed.

The tablets are easy to swallow and have no unpleasant aftertaste. I appreciate that they're gluten-free and non-GMO, making them a great addition to my daily supplement routine
