Vitamin B6, also called pyridoxine, helps maintain the balance of sodium and potassium which regulate body fluids and promote normal functioning of the nerves. Vitamin B6 deficiency has long been associated with various symptomatologies including shoulder and leg pain, swollen hands, "tennis elbow," all forms of arthritis, and even carpal tunnel syndrome.
Two prominent physicians who have helped establish the importance of Vitamin B6 in treating Repetitive Strain Injuries include Morton Kasdan, M.D. (12-year study conducted in Louisville, Kentucky) and John Ellis, M.D. who has treated hundreds of patients with Vitamin B6 over the course of the last 26 years at his practice in Texas.
Most treatments involving pyridoxine are oral in nature and usually dispensed in large dosages. Penetrex uses smaller dosages that can be topically applied directly to the point of discomfort.
