Iron Gluconate or ferrous gluconate same thingI like to grow my hand nails but it everytime breakdown, please which food i have to take?
Calcium, and use a nail product from avon called strong results, dont just put it on once a day, do it as many times a day as you remember, mine are very long and tough, annoying at times cause when you are typing you keep hitting the numbers instead of the letters lol, hope this helps, you can also buy a hair and nail vitamin, I think its by bio-organics or blackmores, goodluck! :)
Just take a daily vitamin.. that will help grow your nails, and make sure you use hand lotion and keep your nails filed so they will not catch on anything and crack or break.
regularlly take vitamines b and c .daily
milk
