Im chiming in, I have been using the pure msm liquid form, for about 4 weeks now and my nails grow fast and strong and I was having hair loss due to hypothyroid and it's almost completely stop, I also use hair essentials for my hair also, I now have just normal hair loss, but I also noticed the crows feet around my eyes have wrinkles and those are starting to soften, so yeah it does work, I just use a tablespoon every morning in my coffee, I doesn't have any taste
