I have low thyroid and have bitten my nails for over 50 years. Seems as hard to quit as quitting cigarettes. However, a few years ago my doctor recommended I take 1000 mg of calcium per day. This really helped, even though I drank a ton of milk per day. I can tell when I skip cause my fingers are in my mouth. It’s a craving for me. Also helped to have my nails cut and smoothed so I don’t use my teeth as a nail file. My nails are still short, but Look better.
