L-Arginine is a crystalline, free-form amino acid. It is an important factor in muscle metabolism and works to transport, store, and excrete nitrogen. Great for blood circulation. I take it before working out and it will give you more energy. Outstanding ingredients in all Source Natural products. Good size, quality and the price is very good too!

L-Arginine is an important factor in muscle metabolism and a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. Unbelievable results after taking these tablets in combination with training. I noticed a difference in my ability nearly immediately, to have more energy and get up and go. I do more now than I used to do regarding housework. I suggest you try this if you need more energy.
