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 read an article that said if you try L-Arginine and you don't feel anything, you don't need it. But if you do feel something, you will need it for the rest of your life. I take this and my energy is through the roof. Great product and helps you burn fat also. Highly recommend.
Works for high blood pressure
Posted by Reviewer2786187 on Dec 15, 2011
L-Arginine definitely works to normalize elevated blood pressure for me, and it works almost immediately. My pressure was about 158 over 90 constantly. Within an hour after taking L-Arginine at about 2,000 mg, the pressure was normalized to about 120 over 80. That was true whether I took it myself or if it were taken elsewhere. Reportedly, it is best taken at bed time to prevent narrowing and hardening of the arteries caused by inactivity during the night. I usually take 2,000 mg on an empty stomach in the morning and the same amount before bed.
Drops Blood Pressure!

Heard that this would lower blood pressure by 20 points using 2,000 mg per day, in just 2 weeks. I tried it and it worked, even more than 20 points!
Best Bang for the Buck!

Don't get me wrong...you will need to take about 4-5grams a serving to FEEL it. Morning,Before a workout and Just before bed. You will actually feel more pumped up due to the Nitric Oxide increase. Your Libido will feel leveled up. You will actually feel something with this product. It is clinically proven. NOW has easy swallow tabs.Great Price.

This is great for avoiding muscle pain the day after heavy exertion...as a side benefit, it is also improves circulation to other areas of the body.
It's All Good!!!

Again with this product I have been taking since I recieved it. I'm no stranger to L-Arginine this stuff is better than Viagra I have been taking 3.5grams a day everyday since I was 45 years old I am 55 years old now and still hang with girlfriends that range from 28 to 40 years old. Not only does it help my "Man Muscle" but it works in maintaining your entire body's muscle mass. I love this stuff, like I said it's all good...Thanks
L-Arginine is King!!

To be honest I read the reviews about about this supplement and bought it based purely on the benefits which it provides in the bedroom. I also take it for the gym and running and it is helping with the flow of Nitric Oxide and blood through the body which I have noticed. I also end up getting a great nights sleep as well.....however my girlfriend has been a little sleep deprived since i started taking it.......I only wish is came in a slow release tab....other than that thanks Iherb you guys rock!!!!
Too many side-effects
Posted by odereviews on Sep 29, 2012
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.
Great for Guys
