I was told about this product from a stranger during my salon visit as she over heard me talking my hair loss postpartum and my fragile nails, she said she had tried and tested most collagen and has finally found the best and gave me rejuvenate details, I think I'm on my 6th bag, and I have the most longest and strongest nails, 37 years I've always picked at my nails and they broke to easily I cannot believe just one little drink a day has made my nails amazing , my hair is feeling fab too , 2 years postpartum was a slog to get through and I'm feeling better everyday and I strongly believe it's because of this drink, just wished i found it sooner, money well spent and will continue to do so! Thank you
