Hao: about a year ago

L-cysteine is a very critical amino acid for maintaining healthy skin and hair. This product contains high dosage and the price is still good. So it is a really valuable choice.

This is the first product I've found that has actually made a difference in the strength of my nails when taken in combination with biotin 1000 mg. I will definitely purchase it again.

Guy: more than a year ago

Honestly I'm somewhat disappointed withs this product; this caplet is hard to swallow, it is large, chalk like with sharp edges. Also they break easily, I did like the idea of the large format as I have to take it 4 time a day for the next 4 months, however I wonder what will be the real count by the end as there is already a bunch of broken pieces at the bottom. This is far from the quality I'm used to expect from any NOW product.
