Great L-Lysine Powder

Posted by 5231496214783765762 on May 25, 2016

I use this everyday and even give it to my cats as it's recommended for them to help boost their immune systems. It must be kept in low humidity as it will clump up some. It does seem to be pure as not having other additives is pure enough for me. I do recommend this L-Lysine product.

Not too sure

Posted by Giordie on May 20, 2016

My daughter insisted that this product was a good idea to add to my looooong list of supplements, can't really say what it does or if it makes any difference, however, i will continue to take it and give it a fair trail

L - Lysine

Posted by 5293071351583895528 on Feb 18, 2016

Although this is for human consumption, not only I use it but I sprinkle a little on my kitty's food. Cats really need L-Lysine because it boost their immune and central nervous system development. It comes sealed and clean, its tasteless and healthful. I do recommend this product which arrived in a timely fashion to my home.

Not up to the stars

Posted by 5629135361106201299 on Nov 07, 2015

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! :)
