L-Lysine HCL Powder
L-Lysine HCL is regarded as a necessary building block for all protein in the body. L-Lysine HCL plays a major role in calcium absorption, building muscle protein and the bodies production of hormones, enzymes and antibodies. L-Lysine HCL is both popular for human and animal health.
Numerous studies have shown that L-Lysine HCL can be used as a preventative and treatment for the cold sore virus.
To some users L-Lysine HCL tastes unpleasant so we suggest when mixing adding a pinch of amino acid flavouring which considerably improves the taste.

Many found it easy to stir into water, protein shakes, amino acid blends or other drinks, with little noticeable flavour when mixed.

I love this product! I take it every day to help keep cold sores under control but also to help with energy. I haven’t been taking long term, but so far so good and won’t stop taking it. The staff are also incredibly helpful.

Great price
Shannon L on 17/09/2026Verified buyer
I’ve been taking L-lysine for a long time and it’s recently been rebranded and knocked up to double the price recently so came here looking for a more cost effective option. Haven’t used it yet but I’m happy it’s cheap, no fillers and if it’s as good as ive found it so far with the other brand , I’m sure I’ll be happy.
Great
