My nails sound just like your's. I remember asking a while back about the vertical ridges that had developed in mine and one kind person told me the ridges were due to old age.

I remember the name of that person, and she's a real sweetie so I won't embarrass her by mentioning her name.

My nails are also soft again at the moment, and I put that down to me being unwell recently. My hair and my nails tend to tell more about my health than my own words can say. My hair stylist can always tell me when I am unwell, if I've been sick or if I have an ailment coming on.

I do believe our nails are a good indication of current health status, but Calcium tablets or gelatin capsules will certainly strengthen them for you.
