I have been using this product (Strawberry flavored gummies) for about a month now, and I have been feeling better, like I have more energy, I don't know if this is because of these gummies or not but this is the only thing I am doing different in my life right now so this is why I would think it's because of these gummies. I haven't really seen anything different with my hair, skin, and nails, but maybe I need to take them longer? or it might be that they look more healthy but I just don't see it, I didn't take a picture of my hair, skin or nails before I started taking these gummies, I guess I should have to see if I seen a difference. But either way I have been feeling good with more energy and if this is because of the gummies then just that to me makes it worth the money I spent on these!
