How to treat heel calluses

Heel calluses are usually heavy calluses extending along the inside of the heel from near the back of the foot to the front part of the heel.

Now I've just read that heavy heel calluses is a sign of insufficient vitamin A over a prolonged period of time. The recommendation is vitamin A (not beta carotene) supplementation for individuals with this problem.

In many cases it can take three to four months to begin to see results, and complete disappearance of the calluses can take eight months or more.
Adults should take 75,000 units a day of Vit A until the calluses are gone. Then you can cut back to a "maintenance dose" of 15,000 to 25,000 units a day.

Please note, though, that heel calluses are not the same as having dry, cracked, and occasionally bleeding heels: That's a different problem.
