Rated 3 out of 5 by from Not as good as what I have been using. The meds is easier to swallow that the large pill I was previous using, but the results are not the same for me.

Rated 5 out of 5 by from Works Well Lysine is an amino acid supplement. Our bodies require a balance of so many different vitamins, minerals, amino acids, etc. Been taking 1 Lysine each morning with 1000 mg of Vitamin C first thing upon rising for a couple years. Lysine & Vitamin C work synergistically off of one another allowing each to do what it should do for good health.

Rated 5 out of 5 by from excellent This is a great product. I've been buying it from Puritan's Pride for years and am completely satisfied. If you can find it on a buy 1, get 2 free sale, even better.

Rated 5 out of 5 by from High Quality I choose these capsules because my friend Oliver, a feline, is lacking a gene that requires me to supplement his food with L-Lysine, and this item in capsule form is incredibly difficult to find. Its so much easier to open a capsule and put the recommended dose on his food, rather than buy caplets and have to crush a bunch a time and place in a food storage container for later use, or worse, crush one at a time as needed, which is daily. Thanks Puritans Pride, for offering this, and at a reasonable price.

Rated 5 out of 5 by from I can't really tell if there is a change. I I have been using this product about 8 weeks now. I haven't seen any changes in myself but I'll continue to use it because I trust Puritan Pride products.

Rated 5 out of 5 by from good product, good price I believe in L-Lysine for overall great health, and have been taking it for many years. I am 67 and will take it the rest of my days.

Rated 5 out of 5 by from Product is excellent. This time when they sent us our order, the heat has caused all the gel caps to fuse together. When I called to report the problem, the customer service said that the hot weather was a real problem this time of year, and so the quickly replaced the order with priority shipping -- the gel caps arrived quickly and were not stuck to one another. I have been positively impressed with the follow up and helpful nature of Puritan Pride and will continue to use them for all my OTC meds.

Rated 5 out of 5 by from take it every day I must admit I strayed away to another company who had better prices and then found out (by using it) they didn't have the desired effects. So on my doctors recommendation I've come back to Puritan Pride products.
Date published: 2014-07-02
Rated 5 out of 5 by from Good product The product is very good but the capsules/pills are way too large for the normal person to swallow easily. It would be the perfect product if the capsules/pills could be made in a smaller form.
Date published: 2014-06-25
Rated 5 out of 5 by from Excellent product! Different things work differently for everyone but I suggest everyone should try Lysine! I've been ordering all my supplements from Puritan Pride for many years now & won't buy from anyone else anymore! Their prices are the best & everything is shipped quickly without paying for express! I can't think of anything bad to say about Puritan Pride! You have to try them, you won't be disappointed!!
