Scientists Figure Out How Vitamin E Keeps Muscles Healthy

Body builders have it right: vitamin E does help build strong muscles, and scientists appear to have figured out one important way it does it.

Vitamin E has long known as a powerful antioxidant, and now scientists have shown that without it, the plasma membrane, which essentially keeps a cell from spilling its contents and controls what moves in and out, cannot properly heal.

That’s a big problem for many cells, such as muscle cells, which get membrane tears just from being used.

“Every cell in your body has a plasma membrane, and every membrane can be torn,” said Dr. Paul L. McNeil, cell biologist at the Medical College of Georgia at Georgia Regents University and corresponding author of the study in the journal Free Radical Biology and Medicine.

The scientist suspects knowing the cell membrane repair action of vitamin E has implications for muscular dystrophy, and common diabetes-related muscle weakness, as well as traumatic brain injury, resulting from collisions on a football field, battlefield, or roadway. With a traumatic brain injury, for example, one of the first events that happens is that the plasma membrane of the neurons, key cells in the […]
