What a difference no fillers makes! It's hypoallergenic

Posted by Health-Is-Wealth on Mar 21, 2014

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.

To balance high arginine intake

Posted by Gondwanaland00 on Oct 28, 2014

This is great to have at hand to balance high arginine intake. It also is a biotin precursor and helps to clear excess ammonia. It can be used topically for cold sores as well. Best effect when taken on its own between (a few hours apart) meals.

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

Lysine for animal rescues

Posted by 5748398956041145935 on Jun 18, 2015

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!!

good powder for vegans

Posted by morganwellinger on Nov 30, 2013

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!
