Lysine is a miracle cure.

Posted by MGG-ThreeTwoFour on Aug 01, 2015

After I got influenza a few years back I got the worst cold sore outbreak I've ever had. I was a mess. A doctor prescribed me an antiviral. Later another doctor who I was having drinks with (and not on the clock) confirmed that the prescription antivirals aren't really very helpful. I've never had any luck with them anyways. She told me to take large doses of lysine (5000 mg a day) each day if I feel an outbreak starting and it should nip it in the bud. I had nothing to lose and lysine is super cheap.This is the best and only cold sore cure out there. It really, really works. I am a convert. I have bottles of lysine everywhere I go frequently, so I am never surprised and miss a chance. I have one when I travel, one at work, one at home, and one at my parents' house for when I visit. ** For new customers of iHerb, please also visit my page for more product reviews **

For the past 4 months I have been having herpes outbreak on the back of my thigh monthly, and it usually comes with a cold. I have been taking it for 2 weeks now to hopefully keep the outbreaks at bay. Still too early to say but I have noticed that my immune system has gone up. Surrounded by sick people and surprisingly I'm not sick!

Immune Support

Posted by Reviewer1604997 on Nov 26, 2014

My physician suggested I try L-Lysine (an essential amino acid) as an immune booster. After researching the various products on iHerb, I chose the Now Foods brand as it is pharmaceutical grade and is free of common allergens (wheat, gluten, soy, corn, milk, egg). I also give L-Lysine powder to my cat.

Great value. Pills a little big if you find it hard to swallow. Excellent product overall.

It is an essential amino acid for humans in very good quality.

Lysine (abbreviated as Lys or K)[1] 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.[2]) 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.
