Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4.9 out of 5 by 9 reviewers.
Rated 5 out of 5 by Best value for lysine I give this to my cats and mix it in their wet food. This product is the best value for lysine and much easier than grinding tablets up for every meal. It is grainy though and does not dissolve easily in liquid. Sometimes it clumps together when wet instead of dissolving. Depending on the texture of the food I am mixing it in, sometimes I still have to grind it in a mortar and pestle so it will blend in. But being grainy it is less prone to turning into a dust cloud than grinding tablets. August 19, 2016
Rated 5 out of 5 by Effective This is a pretty good way to take Lysine, especially if you have trouble with pills. You can add it to a fruit or protein shake and it tastes fine. The only thing I don't like is that when you spoon it up, it's very fly-away, kind of like what electricity does to your hair. May 15, 2015
Rated 5 out of 5 by PREFERRED I prefer to use L-Lysine in this pure powder form. It has a naturally salty taste and stirs / shakes / mixes into any liquid very easily. Taste is compatible with most anything, and not an issue. For wellness and growth, I like to use dosages of 3 to 5 grams, and I would rather put this powder into one of my Healthy Green Cocktails than add a lot more capsules or tablets to my daily regimen of supplements. I also give L-Lysine powder to my dogs and horses. I have used L-Lysine for decades, and I recommend it. May 23, 2013
Rated 5 out of 5 by A product with no additives is hard to find so once found you keep coming back. I'm on my 3rd bottle so yes I am a repeat buyer of this supplement due to there being no additives. September 28, 2012
Rated 5 out of 5 by So Conveniant Love adding this product to my smoothies. It adds no taste and is effective, . April 18, 2012
