Could CoQ10 Make Thoroughbreds Run Faster?

In a study of Thoroughbreds, it was discovered that supplementing horses with Co-enzyme Q10 (CoQ10) increased the activity of slow-twitch muscles.

In this Canadian Thoroughbred article, we look at the results from a 2017 study, which examined the difference between “sprinters” and “stayers” on a genetic level.

Researchers studied the Myostatin (MSTN) gene, which regulates muscle mass by limiting the number and size of muscle cells/fibres. Using muscle biopsy techniques, they learned that different muscle fibre types have different capacities for contractile speed and energy metabolism.

Horses have three different types of muscle fibres, the make up of which depends on the breed, and it is these differences that make Quarter Horses adept at sprinting, Thoroughbreds able to run upwards of two miles, and Arabians able to cover 100 miles in a day.

Further the researchers discovered that supplementing horses with Co-enzyme Q10 (CoQ10) increased the activity of one type of fibre known as “slow-twitch muscles” by 40%. CoQ10 is an antioxidant that horses produce naturally. It has an important role in the cellular process, and is essential for the production of biological/chemical energy.
