Fantastic for cold sores
Posted by Reviewer1091251 on Aug 12, 2011
This shipment came just in time. My Son developed a large coldsore and within 1/2 an hour of taking Now Foods' lysine, the pain was gone and a couple of hours later the coldsore had visibly shrunken and was on the mend.

I keep L-Lysine on hand to help prevent cold sore outbreaks. If I take lysine as soon as I feel an outbreak coming, it will usually stop it. This is a must have item for me to keep on hand.

This product is a great value...I take it after my work-outs as part of my recovery protocal.

Using it to reduce and prevent herpes attacks. It ended a very long cycle of outbreaks within a week. Been as good as gold ever since.

Tablets are large & need to cut in half. Will go back to 500 mg capsules for easier ingestion. Take this product to fend off cold sores and so forth. Works well.
Just what I need

I am a big fan of Now Foods products, and this one is no exception. My favorite thing about it is that it only contains L-Lysine and not other nutrients that are probably covered by my multivitamin.

I have not had hardly any cold sores since taking this product faithfully.... so exciting!
Dont waste your money! Pills are utterly huge and untakeable.

I can take most pills but these are the worst. After a nasty bout of fever blisters I decided to start on Lysine but wasted my money here. The pills are large in size (length ways) but probably the thickest (depth) pills I have ever taken (I take roughly 20 pills and supplements a day for a variety of conditions). They are so large it is almost impossible to cut them and if you do, they are still too thick to swallow when cut in 1/2. When cut roughly into quarters, I still struggle to get them swallowed as they are very angular as well. Definitely the worse pill I have come across. Out they went!
It is an essential amino acid for humans in very good quality.

Lysine (abbreviated as Lys or K) is an α-amino acid with the chemical formula HO2CCH(NH2)(CH2)4NH2. Lysine's codons are AAA and AAG. Lysine is a base, as are arginine and histidine. The ε-amino group often participates in hydrogen bonding and as a general base in catalysis. (The ε-amino group (NH3+) is attached to the fifth carbon beginning from the α-carbon, which is attached to the carboxyl (C=OOH) group.) Common posttranslational modifications include methylation of the ε-amino group, giving methyl-, dimethyl-, and trimethyllysine. The latter occurs in calmodulin. Other posttranslational modifications at lysine residues include acetylation, sumoylation, and ubiquitination. Collagen contains hydroxylysine, which is derived from lysine by lysyl hydroxylase. O-Glycosylation of hydroxylysine residues in the endoplasmic reticulum or Golgi apparatus is used to mark certain proteins for secretion from the cell. This product help me with herpes zoster.
