Omega 3 Fatty Acid Supplementation For 12 Weeks Increases Resting And Exercise Metabolic Rate In Healthy Community Dwelling Older Females

This study examined whether omega-3 fish oil supplements could help counter some of the metabolic changes that naturally occur with aging. As we get older, our metabolism typically slows down, we lose muscle mass, and our bodies become less efficient at burning fat for energy. These changes can increase the risk of chronic diseases and reduce quality of life.

Researchers studied 24 healthy women around age 66, randomly giving half of them 3 grams daily of omega-3 fatty acids (EPA and DHA from fish oil) and the other half a placebo (olive oil) for 12 weeks. They measured various aspects of metabolism, body composition, strength, and blood markers before, during, and after the supplementation period.

The results were quite impressive. Women taking fish oil experienced a 14% increase in their resting metabolic rate (how many calories they burn at rest) and a 10% increase in energy expenditure during exercise. Even more notably, their fat-burning capacity improved dramatically - increasing 19% at rest and 27% during exercise. The fish oil group also gained 4% more lean muscle mass, improved their functional capacity by 7%, and reduced triglyceride levels by 29%. Meanwhile, the placebo group showed no significant changes in any of these measures.

These findings suggest that omega-3 supplementation might be a valuable strategy for maintaining metabolic health as we age. At VALIA Health, this research supports our approach of using targeted nutritional interventions to optimize metabolic function and support healthy aging, particularly for patients concerned about age-related metabolic decline.
