Why have I got vertical ridges on my nails?

I eat really healthily, exercise loads and I'm only 25, I don't smoke and only drink every so often, so why have I got vertical ridges on my nails? They are most prominent on my thumb nails and I think they've got worse recently. Apart from this my nails are pretty healthy and strong.Why have I got vertical ridges on my nails?
i get the same thing....someone told me vitamin B helps. i started taking extra vitamin B, and i haven't noticed a huge difference. vertical ridges are natural and aren't anything to worry about....horizontal ridges can indicate a major health problem.


i have horrible vertical ridges in my nails, so i buff them to make them more even and then coat them with 2-3 coats of clear nail polish that is enhanced with strengthener.Why have I got vertical ridges on my nails?
Drink more milk. You need more calcium and vitamins. Some people get them easier than others. But it's not a big deal.
I've been told that's from not getting enough vitamins
