Protein Supplements May Not Help Older Adults Build Muscle

A recent study published in the Journal of Nutrition found that consuming protein supplements did not help active older men build more muscle or gain more strength than resistance exercise training alone. Forty-one men with an average age of 70 completed whole-body resistance training three times a week for 12 weeks. Half the group drank a supplement containing 21 grams of protein after exercise and every night before bed. The other half drank a beverage with the same number of calories but no protein. At the end of the study period, while both groups were able to lift more weight and tests showed increased muscle mass, the protein group did not improve any more than the placebo group.

A recent study, published in The Journal of Nutrition, looked at nutrient and herbal supplement use in U.S. adults. The study surveyed over 3,400 people ages 60 and older between 2011 and 2014. About 70 percent of respondents reported using at least one dietary supplement over the previous 30 days, says study co-author Johanna Dwyer, DSc, RD, senior nutrition scientist with the Office of Dietary Supplements at the National Institutes of Health and director of the Frances Stern Nutrition Center at Tufts University. Older Americans may want to rethink this practice, however, since a growing number of studies have found that supplements may not have the intended health benefits. Additionally, more information is needed on potential interactions between supplements and prescription drugs.
