A member asked:

Fingernails have cracks and are very brittle. have been taking synthroid (thyroxine) for years. is there anything that i can take to improve my nails?

A doctor has provided 1 answer

Just make sure: You are on the correct dose and your blood levels are normal. The cause of your brittle nails is more likely related to other medical problems such as your intestinal disease.
