Omega-3 fatty acids might promote muscle growth in older adults. Omega-3 fatty acids, which are plentiful in many kinds of fish, improve blood vessel health, cell membrane strength, and prevent heart attack and stroke. Animal studies found that Omega-3s also stimulate protein synthesis. Muscle loss (sarcopenia) is a significant problem in older adults because it limits mobility, impairs bone density, and decreases metabolic health.
A University of Washington Medical School study showed that supplementing Omega-3 fatty acids promoted muscle protein synthesis in older adults. Older adults should take Omega-3 fatty acid supplements to promote heart health and prevent muscle deterioration. (American Journal of Clinical Nutrition, 93: 402-412, 2011)
