Wow these are good stuff, I bought them for my hair and skin, only been taking them for a week, haven't noticed any difference in my hair or skin in a week to early to comment but boy my nails have changed I normally bite them and have for years, my nails are now so tough I can't bite them, this is brilliant considering it's only.been 7 days, hoping they will help my skin, and hair soon, can't expect miracles but in such a short space of time that's pretty good going, you only need one a day so that's 4 months worth for under 8 pounds, you really can't go wrong with these excellent value for money, thank you 😁
