What a difference no fillers makes! It's hypoallergenic

Posted by Health-Is-Wealth on Mar 21, 2014 | Verified Purchase

I read somewhere that a diet low in lysine may also result in low taurine (though the mechanism/why was not understood) - certainly seems to have proven true for me. I seem to benefit more overall supplementing taurine though a bit of extra lysine appears to be good for hair growth/thickness. Having tried caps/tabs I'll always get pure powders where possible - the stearates/most fillers in caps/tabs always cause me to wheeze, regardless of product/brand. This is a good price - product is true to label and I like the container which allows easy access to the contents (unlike some with narrow bottles/openings). Product arrived with seal in tact though I suspect customs had checked it because lid was loose and seal looked like someone had poked it (same for another powder I got in same order). Not sure re bad taste that another reviewer noted - not an issue for me. If this review was helpful to you, please click YES below - thank you.

Lysine for animal rescues

Posted by iHerb Customer on Jun 18, 2015 | Verified Purchase

Lysine can be a life saver for cats and kittens infected with 'cat flu and can also be used as a preventative for cats and kittens in times of stress, particularly coming from pounds, as Lysine boosts their immune systems. This product is a natural, unflavoured powder, perfect for sprinkling on their food, or added to drinking water. Brilliant product, brilliant price, brilliant company. You couldn't ask for more!!

I've tried a few brands, but this one dissolves best in water. The wide mouth of the container makes use easy.

Thanks for your feedback!

good for cats

Posted by iHerb Customer on Jun 28, 2011 | Verified Purchase

very good for my shelter cat who had a cold. Now he is feeling much better thanks to L-lysine and vitamins.

Thanks for your feedback!

I bought this specifically to help my cats who developed conjunctivitis. I only had to use it a couple of times before seeing some great results. The swelling in their eyes went down overnight and they had fewer tears and goop. It's also beneficial to humans in relieving inflammation so I may start using it soon.

Thanks for your feedback!

Great for viral infections in cats

Posted by iHerb Customer on Jan 03, 2014 | Verified Purchase

My vet recommended L-lysine for the cats/kittens I was rescuing from a feral colony. Many of them had viral infections that caused eye and upper respiratory issues. I can add this powder to their dry or canned food. It does seem to help boost their immune systems and help keep the viral stuff under control.

good powder for vegans

Posted by morganwellinger on Nov 30, 2013 | Verified Purchase

vegans tend to lack l-lysine in their diets (along with cats) so i wanted to get a good supplement. this seems to do the trick!! the taste is pretty wicked though, but still awesome product for the price!

Thanks for your feedback!

Not up to the stars

Posted by iHerb Customer on Nov 07, 2015 | Verified Purchase

I was taking 21st century L-lysine for my mouth ulcers and they worked well.. But I thought I'd give this powder a try since it had pretty good reviews. Sadly it didn't do anything about the ulcers after a week.... So I went out and bought another bottle of 21st century and too 2 tabs last night and the ulcer on my tongue has subsided by a lot! I'll still continue to take the powder for preventive measure.... Hope they at least help in that aspect! :)

Thanks for your feedback!

doesn't disolve

Posted by iHerb Customer on Mar 20, 2014 | Verified Purchase

it only completely disoleves when I mix it with MSM.Good amino acid. Great for your tissue.

Thanks for your feedback!
