I started using Osteonorm when I became pregnant last year. I've used different calcium tablets before and none of them have really done any good for me. Once I started using Osteonorm I noticed that my nails and my hair started growing better. My little one is now seven months old and I still take it. And I couldn't recommend it enough really. My little one, when she was born, she already had quite strong nails on her. I really recommend it for anyone that's pregnant or had a baby because it really does work miracles.
