Folic Acid for Weak Nails

I see a Thyroid Specialist for hypothyroidism. I was complaining about my weak, brittle nails when he suggested that although my thyroid was functioning properly (too much or too little thyroid function can cause weak nails), that I may be deficient in folic acid. I'm not as faithful about taking my vitamins and supplements as I should be, but I do notice that when I take a folic acid supplement that my nails become stronger and break less often. You can buy folic acid as an individual supplement, but you can buy multivitamins with folic acid in them.
