I trust its efficacy and purity

Just as with creatine, much of the world's MSM supply is produced in unscrupulous Chinese factories, where purity is unregulated. This product's OptiMSM brand is the only way of being sure that the MSM is produced in the USA.

Not too strong

Isn't sour or overwhelming in its flavor and dissolves readily. Recommended if you need extra Vitamin C and don't want tablets.

I took it initially for hair and skin. Not only did i lose hair on this product, my digestive system got screwed up. I am suffering from bloating and constipation. and i am afraid i am going to gain weight as my digestive system is very sensitive. i would have given a minus star instead of a star if possible.
