Prior to the July 2018, Lysine HCL was known on the Bulk Nutrients website as L Lysine. No formulation changes have occurred during the name change to Lysine HCL.

Lysine HCL

Lysine HCL is regarded as a necessary building block for all protein in the body. Lysine HCL plays a major role in calcium absorption, building muscle protein and the bodies production of hormones, enzymes and antibodies. Lysine HCL is both popular for human and animal health.

Numerous studies have shown that Lysine HCL can be used as a preventative and treatment for the cold sore virus.

To some users Lysine HCL tastes unpleasant so we suggest when mixing adding a pinch of amino acid flavouring which considerably improves the taste.

Lysine HCL is very hydroscopic which means it'll absorb surrounding moisture and may clump. This may lead to a hardening of the powder, which will not decrease effectiveness, but it can be minimised by keeping all air out of the pouch and storing it in a damp free area.


Consume 1000mg of Lysine HCL once or twice daily.

As the serve is very small, we recommend using microscales when dosing.


Combine powder with liquid and consume immediately.

    2nd Chance Cat Rescue

    Posted by Daniela on Jul 29, 2018

    At 2nd Chance Cat Rescue we use Lysine all the time to prevent the kittens and Cats we get in getting cat flu. Lysine is such a fantastic product which helps in the prevention of herpies.
    We recomment Lysine to every cat owner. We order it in , in BULK and go thru a few Kilos a year!
    We do have a giggle when we swap the little bags of white powder at meetings. Lysine is a wonder powder and we LOVE it.

    5 with dissolvability

    Posted by Jani on Jan 23, 2018

    This product is excellent and could be a 5 star product if made slightly more dissolvable. Maybe you can make it finer easily and then it won't clump into hard lumps that take a while to dissolve. Our solution is to put it in water 10 mins before we want to drink it and then stir it for an extended time. If you get a lump it's very unpleasant. This is designed to be constructive comment. We take this product to prevent cold sores and it is pretty effective.

    Great price!

    Posted by Tracey on Jun 08, 2017

    A great price for this amino acid. Yes it tastes (and smells) a bit awful but I mix it in with other amino acids to make a post-workout mix and it's fine.

    Top quality at a very low price - plus cheap and fast postage. Why would I want to buy it anywhere else?

    Balancing arginine and l lysine with supplements

    Posted by Jani on Apr 11, 2017

    I have had trouble with arginine rich foods triggering cold sores. By taking l lysine, I can create a balance, and prevent outbreaks. I've tried tablets, but powder is far superior.
