Good product. Make sure you supplement with Lysine also. This product made me feel great until my lysine stores were depleted then I felt hugely tired. Started taking lysine then I felt great again.

I bought this for slowly healing wounds, but I've been suffering from bad side-effects, caused by L-arginine. I can't recommend this at all. I'm a nice guy, but L-Arginine makes me angry all the time, tired, and my energy levels goes low. I haven't noticed a single good thing when taking this supplement.

I take this to help with weight lifting and to increase my libido. For a 42 year old male, I highly recommend this product.

My wife suffers from Multiple Sclerosys and her MD told her to take Arginine when she feels tired. It works.

Ive always had the loose powder which worked well, but this is not so good, I use it to control my BP and it doesn't work as well as the loose powder I get, I think there might be something else in these. Have found out why this has not worked it is full of a very dangerous MAGNESIUM STEARATE which is for the machinery making up the pills , which STOPS the ingredients from dissolving in your body

L'Arginine is reported to reduce blood pressure and help men with manly issues as well. My husband has been taking these capsules. He prefers to take the 500 mg capsules to the 1000 mg tablets. They are smaller and easier to swallow. He has been feeling great after taking this product for a month. He has more energy and I can attest to the enhancement of male sex drive. He can't leave me alone. Definite increase in this department. All round great benefits and Now Foods is a great brand. I highly recommend this product. It's me now, the husband, and yes, I walked by an attractive looking tree today. Could have been embarrassing but I managed to gain control.
