Customer Ratings & Reviews

Free-Form L-Lysine is rated 4.8 out of 5 by 55.
Rated 5 out of 5 by from Quality and Price This is a newer supplement for us. Have done some research and found out how much our bodies need this and are lacking in it today. So we supplement with one of these in the morning.

Rated 5 out of 5 by from works wonders I recently ran out of my Swansons brand L-Lysine and bought GNC for convenience. Well I might as well have been taking sugar pills for all the good that it did. Now I'm a truer believer in Swansons quality.

Rated 4 out of 5 by from Free-Form L-Lysine L-Lysine does several good things for the body. I take this one twice a day, since I don't get too much in my diet.

Rated 5 out of 5 by from Great Product When I did some research on vitamins for stress relief, I came upon this site on a suggestion from a friend. I desperately needed some help with stress relief after a health failure due to personal and work related stress. After taking this for some time, it has helped me tremendously . I also incorporate exercises to help deal with additional stress from time to time. Thank you Swanson! I have told friends and family about this site. Please keep up with the quality of your products and prices. I`m a returning customer.

Rated 4 out of 5 by from Lots of pills for little cost. 300 to be exact, for about the same price of a combo meal at a fast food restaurant. I took this along with another supplement to counter a condition effectively. That condition I cannot tell you sadly, due to governmental regulations on posting medical or disease claims on this site. I will say that you get a decent-quality amino-acid with no less than a 100 days' worth at the suggested dose. :)

Rated 4 out of 5 by from It works as intended I much prefer these 500mg capsules to the 1,000mg pills I have taken before. The pills are huge and very hard to swallow, but these caps go down easilly. Lysine is great to help rebalance your lysine/arginine ratio when you over indulge in those arginine rich foods like certain nuts. No need to try and eat lysine rich foods , just take these as recomended on the label and avoid all those extra calories! Lysine seems to live up to expectations!
