Rated 5 out of 5 by from Quality product My husband has taken l'arginine for years. I buy him Swanson's Ajipure as this is the best product for the best price. I can't rate effectiveness since I'm not using it.

Rated 1 out of 5 by from Warning! - if you sometimes get cold sores I took this L-Arginine as stated on the bottle, and read all the Swanson reviews. After only 3 or 4 days I got a cold sore breakout, which is usually infrequent for me. So I stopped taking it and did more research online and found that L-Arginine may encourage a breakout in people who already have the virus, "feeding" it so to speak. What a bummer! I was so hopeful to try it out longer and experience the energy boost that some folks get from this amino acid. I'm sure this is a great product, but everyone reacts differently to things, so I am just saying do your research. I hope Swanson will leave this review up because i would have really appreciated seeing it before I bought the product. Thanks.

Rated 4 out of 5 by from Hard to say As always, Swanson has a good price on this supplement. I believe the overall quality of Swanson supplements to be good. It seems that I have been a little better since taking this supplement regularly but I'm also taking other things that might be contributing to overall improvement so it is hard to say that this specific supplement is helping a lot.

Rated 5 out of 5 by from Great Purchase I always use Arginine before and after work outs. It gives my energy and going all day long. It is excellent buy. I have been studying vitamins and nutrition for about 25 years and know what is good.

Rated 5 out of 5 by from Hi honey...I'm home!! When I combine this product with Swanson Premium L-Citrulline Malate Complex, I stand tall! I know that Nitric Acid levels are important, and I do what I can to raise those levels. It makes for a happy marriage. ( 30 years ) No gimmicks from Swanson.

Rated 5 out of 5 by from Really good product I have used this for a couple years now and combine it with another supplement that it works great with. When I'm in the gym, I can literally go for a couple hours of working out and still have energy to go. Recovery next day is great and as you get older it's nice to feel good the next day.

Rated 5 out of 5 by from Feel the effects I take one capsule with my morning breakfast and I feel the good effects. I have avoided taking any with dinner since many of the foods I eat then contain L-Arginine anyway.
Date published: 2012-09-03
Rated 5 out of 5 by from maybe Not sure if I am benefiting from this product or not. Long term use will tell. I like the fact that it is processed differently than other arginine products.

Rated 5 out of 5 by from Dirt cheap when I bought it BOGO This was dirt cheap when I bought it. Got 6 bottles for the price of 1 regular bottle. Gotta love BOGO. It was a great value, only catch is the number of caps you have to take to get a proper dose of L-Arginine: 6!!

Rated 3 out of 5 by from None results yet I have been taking this product for about 4 months and still don't see a difference at all. I still have some and I have read it might take up to 6 months with supplements to start experiencing some difference I will continue for 2 more months and see what happen.

Rated 5 out of 5 by from Effective Good value for a product that has improved my performance noticeably. I take two a day which works well for me.

Rated 5 out of 5 by from A worthwhile upgrade I have been taking Swanson's Premium L-Arginine for a couple of months and these were 2 for 1 so I indulged. I can't see anything in the labeling that makes them any different other than the product title. Even so - they seem to have an extra kick to them of effectiveness and if you are looking for this product I don't think you'll be disappointed with this website, this product and these prices.
