L-Arginine is rated 4.7 out of 5 by 41.
Rated 5 out of 5 by from Another great Swanson's Product! L-Arginine is part of my daily regimen that assists the old guy with healthy circulation, which I have found to be helpful, and would highly recommend!
Date published: 2017-01-05
Rated 1 out of 5 by from Completely ineffective Compared with other L-Arginine products, this one is positively impotent. To be effective it needs L-Citrulline with it.

Rated 5 out of 5 by from It Works Hubby and I are both happy with the results from taking this. We take it twice daily and it has made all the difference for us and has not let us down. Will continue to take.

Rated 5 out of 5 by from Good Amino to Have Around When I was younger this amino was great for getting that "pump" when working out. Now that I'm middle aged, I'm happy to take it for improving my circulation and as a male tonic. You can really feel this amino going to work if you take it by itself. Swanson's brand is great too.

Rated 5 out of 5 by from Swanson's L-Arginine L-Arginine is so important for our bodies, in so many ways. It is really hard to get this amount just from daily diet alone, and so I take this amino acid daily. Great price for this amount as well. Thanks Swanson!

Rated 5 out of 5 by from BEGINNER ARGININE Starting out, I used the 500 mg. L-Arginine capsules, because that is what was available and what I was aware of. I took 4 capsules at a time to get the 2 gram dose I wanted. I felt that I was getting good results from my two grams of Arginine along with the other Aminos I took with it. Then, the more reading I did and the more I found out led me to larger dosages, at which time I found Swanson's 900 mg. and 1,000 mg. Arginine capsule products, as well as Swanson's Arginine powder. These all work great for me, and I am in complete control of the potency and number of capsules or amount of powder I want at any given time. I make sure to take ample L-Arginine at least twice daily for my muscles, heart, circulation, and overall wellness and fitness. I find that L-Arginine produces the noticeable, favorable results I am looking for. It's all positive for me. I heartily recommend it. And at Swanson's very reasonable prices, L-Arginine 500 mg. capsules are extremely affordable.

Rated 5 out of 5 by from L-Arginine 500mg - take 2 caps I have been taking 1000 mg of this product for a few years now, just before bedtime, and I've no more problems with sleepless nights any more.

Rated 5 out of 5 by from L-Arginine I really appreciate what L-Arginine has done for me. It has helped me in many ways.
Date published: 2012-12-16
Rated 5 out of 5 by from Good Product, Good Value I have been taking this product for quite some time. It does work very well but if you add a small amount of L Citrulline with it, the combination works much better. For me at least. I take 2000 mg of the L Arginine and 850 mg of the L Citrulline per day. Took me about a week to recognize results.
Date published: 2012-06-01
Rated 5 out of 5 by from Excellent product I take this product before going to the gym to give me a little extra energy during my workout and I have great success with it. It increases blood flow, which also helps in the bedroom. I take 4 pills and it does the trick. I recommend it and as always, Swanson's prices are the best.
