Since the last 2 or 3 years, my nails got thinner and weaker. They would break easily and I had to keep them so short that it was painful. My doctors could not figure out the cause. They prescribed vitamin B thinking that it was a consequence of being a vegetarian. However, I had been a vegetarian almost my whole life (more than 20 years!) and this was something new. By chance I was listening to Donna Schwenk podcast on fermented food and she mentioned the importance of minerals.She said that independently of having a good diet, she took mineral supplement due to the health of our soils (depleted of minerals). She mentioned that she takes Body Ecology and mentioned that she has nothing to do with the brand. Since she gives lot of good information for the sake of helping, I like and respect her. So I decided to try these minerals. It was incredible because in less than a month my nails were stronger. After a month, my nails were normal. And I had spent years with this problem. Now, if I do not take the minerals for 2or 3 weeks, I revert to the weak nails. It is sad because this is also telling me how bad our soils are. But I am happy I found this product!
