does it's job

happy with it

Thanks for your feedback!

I like it!

Posted by iHerb Customer on Apr 22, 2017 | Verified Purchase

Like this product very much, because it helps me every time when I get herpes. At first signs I start to take a pill on every 3-4 hours. On the next day I take 4 pills and the two days after - 3 pills daily. I usually continue to take a pill every other day for at least a week. I've also noticed that herpes attacs are rare's been a year or so since I use L-Lysine.

Thanks for your feedback!

Choking hazard

Posted by iHerb Customer on Oct 06, 2016 | Verified Purchase

The shape and size of these pills make them very hard to swallow. Even my large fish oil capsules go down easier than these Lysine tablets. I have to position them a certain way so I don't choke on them, and even then they still go down hard.

Thanks for your feedback!
