This product works. I use it regularly for health issues and it is effective.

On some research I opted for this product as price and value seemed very good.I am very happy with my choice, this powder is easy to integrate into my smoothie in the morning, no taste on its own and so far it seems to help clear up herpes nicely. Overall great choice

Good product recommend it 👍

I'm not using this to supplement my diet as I eat enough beans, cheese and yoghurt already. However, my cat Bennie has been diagnosed with Feline Calicivirus (FCV) which is a sort of cat flu that recurs. Many cats carry this virus and just spread it around and never fall sick but as my cat was a mistreated RSPCA rescue cat his ability to fight FCV off was compromised. So Lysine to the rescue! Giving 1/4 of a teaspoon (about 1/2 gram) acts as a protein building block not a drug and *assists* Bennie in fighting of the effects of the Calicivirus or Herpes virus when it attacks. Bennie's symptoms are sneezing, runny eyes - typical 'common cold' symptoms in a human. Lysine helps Bennie trick the virus into self-destructing by using this L-lysine instead of its preferred protein Arginine. Since starting this his early symptoms disappear almost immediately. Was it the Lysine or one of the other homeopathic remedies (including Vitamin C) we use? I don't know but I'm not going to stop using this just to find out. It's only necessary when we spot the tell-tale signs of an infection and this powder is reasonably bland enough to hide in his food. Given the small dosage for a cat this pack will last for some time. Any excess is excreted out so it harmless if not required. Good value and perfectly safe and Bennie say 'Great'!

bought this to counter a negative effect of taking citruline/arginine supplement, ( I had been taking to help maintain my cardiovascular system,) but getting undefined groups of spots, sometimes like mini hives for couple years. The dermatologist thought eventually I may have vascular dermatitis ! More recently I got a more defined rash of spots across my chest & doctor thought I had mild dose of shingles. I read about Lysinine taken with Arginine for herpes Rosta so bought this & 'Voila'. - No more spots& Whose a clever boy then!? Well pleased. (But of course, trusting it does'n't negate the POSITIVE effects of taking citruline/arginine ! (Who knows? Fingers crossed it continues if it doesn't!)

Purchased because I could no longer swallow the huge tablets. I found the easiest way to take it and mask the flavour was to add the powder to about 50-100 ml of tepid water and give it a good stir to dissolve, then add a sharp juice, Cranberry works exceptionally well, (also tried tomato, and orange/carrot/turmeric with great results) up to 100-125ml and stir again, and drink immediately. I would definitely buy this again.

Ok, big canister for the money
