AQHA Funded Study Conducted at Gluck Equine Research Center (2013)

In 2012, the American Quarter Horse Association funded a research grant to investigate the metabolic effects of resveratrol administration in horses.

This research study was performed in 2013 by Dr. Amanda Adams at the Gluck Equine Research Center. In this study, 45 days of continuous Metabarol administration reduced insulin levels by 25-30% in horses enrolled in the study. Results independent of diet.

There have been numerous peer-reviewed scientific studies published that demonstrate the metabolic effects of resveratrol administration. For a summary of this research, including literature citations, see below.

Resveratrol was the first compound identified to activate Sirtuin 1 (SIRT1)1, an enzyme that activates and deactivates select genes to improve metabolic function and enhance muscle performance. SIRT1 also is induced by exercise and caloric restriction. 2-5 Thus, resveratrol administration may offer some of the same health benefits of exercise and caloric restriction through its similar effects on SIRT1.

Resveratrol has been found to have the following therapeutic effects relating to metabolic function and muscle performance:

  • improves insulin sensitivity5-8

  • promotes mitochondrial biogenesis, the production of mitochondria in cells5,8

  • increases the efficiency of energy-producing metabolic reactions in mitochondria8,9

  • improves muscle recovery after exercise10

  • supports muscle tissue health with aging11,12
