I begin taking these in the fall. My nails get bad in the winter; ridges, dry and brittle. Gelatin has always helped my entire life, and I am 70. Takes a while to work (think nails growth from the nailbed). I told my hair stylist about them, she is much younger. She said it makes sense, it's protein. I have always had good luck with the Now brand.
I am using this product for months, I feel the difference especially with hair and nails, , the hair is more soft and easy to handle and the nails are pretier and stronger it does have any smell , shurely buy it again
I am very satisfied with this vitamin and recommend it to anyone looking for a boost of energy. I didn't want to take regular supplements because they always made me feel tired and weighed down, but that's not the case with this one
