I have been using this product for over a year. I take a heaped teaspoon every morning in my coffee, no taste too!! I noticed my nails became harder and healthier. I did try this product for my hair as it was struggling to grow, now I couldn’t be any happier my hair has grown and looks so much more healthier looking too, even my hairdresser commented “what are you using?”My skin is a lot more dewy looking now but I think my wrinkles have softened. Really pleased with the results and have tried other expensive brands in which I felt I got way more results from this product being way cheaper too.
