Great Value - Fishy Odor A fantastic value. I don't care for the way the capsuls smell. I would like a tablet. Capsuls are harder to swollow for me during pregnancy. November 19, 2010
Doesn't work for me I didn't understand why these capsules did not work well for me until I read the review by SwansonsFan1. Tablets work great for me therefore I cannot recommend this product for anyone that is looking to boost their lysine while dimishing the arginine in their body. I am disappointed as this is the only Swanson's product that does not work for me. September 1, 2010
The Best I've used different mfg's lysine over the years and Swanson's outperforms all of them. A great product at a great price! May 8, 2010
great product Since I'm not allowed to make medical or disease claims, just like one of the other reviewers I can tell you this product works! The only disappointment is the gelatin cap, which has arginine in it, which is counter-productive to the effectiveness of Lysine. Maybe in the future it will be a veggie cap. Other than that, this is an excellent product & Swanson rocks! August 8, 2009
Best supplement L-Lysine is an essential amino acid needed for human body. It keeps me healthy and energetic. July 30, 2009
Results, results, results! L-lysine has proven for me to be the immune boosting, cell nourishing and rebuilding supplement that I've needed for a very long time. Swanson's Free Form L-lysine capsules are high quality and effective in meeting all the sought after benefits I keep taking it for! July 27, 2009
Great product! I take this twice a day almost every day. The only inconvenience with L-Lysine is you have to take it on an empty stomach. This product does exactly what it's supposed to. I really like the capsules and feel they are more easily metabolized. I panic if I run out and enjoy the excellent service Swanson provides. July 23, 2009
Necessary component I take this as part of the Pauling or Rath protocol and the combination of this and other amino acids and supplements really works for me! I highly recommend it. July 22, 2009
Excellent product I've used different brand of lysine over the years and this one is the best. Its easy to swallow capsules allow for regular usage. Would highly recommend. July 1, 2009
all good! all amino acids are good and effective to me. i would recommend this product! it's best to take these before or after a workout. February 23, 2009
An everyday supplement for me Good immune system support. I eat lots of nuts and this balances the arginine they contain. I use one 2x a day. May 22, 2008
