Omega-3's Counter Degenerative Muscle Loss

Daily supplements of omega-3 fats could boost the production of muscle protein in older people.  Four grams per day of omega-3’s increased the rate of muscle protein synthesis.

In the U.S., 45 percent of over-65 year-olds are thought to be affected by sarcopenia, a loss of lean body mass, strength and function. A person in their 20’s usually has muscle that is up to 60 percent fat-free mass, but this drops to less than 40 percent for a 70 year-old.

According to the study in the American Journal of Clinical Nutrition:

“Corn oil supplementation had no effect on the muscle protein synthesis rate ... [But omega-3 fat] supplementation ...  augmented the hyperaminoacidemia-hyperinsulinemia–induced increase in the rate of muscle protein synthesis ... Omega-3 fatty acids stimulate muscle protein synthesis in older adults and may be useful for the prevention and treatment of sarcopenia.”
