This thread deserves love as today my nails started to break like crazy without even the slightest stress put on them.
I checked the first link against my FitDay nutrition record and it seems I need to up my Vitamin D intake to fix it (am averaging 58% of required intake per week...).
A big thank you to Korn for posting this!
