What is Potaba?

Potaba is a form of Vitamin B, which supports many important body functions.

Potaba works by softening the skin or tissues and raising oxygen levels in tissues of the body.

Potaba is used to treat conditions that cause skin or tissues to harden, including scleroderma (skler-oh-DERM-a), dermatomyositis (der-mat-oh-mye-oh-SYE-tis), and Peyronie's (pe-ROE-neez) disease.
