Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids.
Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.

The findings appear in the journal Scientific Reports.

Participants were randomly assigned to the two groups. The exercise regimen combined strength training and high-intensity interval aerobic fitness challenges.

One group received the nutritional beverage and the other consumed a placebo beverage that lacked the added nutrients. Neither the researchers nor the participants knew who received the nutrient-enriched beverage or placebo.

The exercise intervention alone improved strength and endurance, mobility and stability, and participants also saw increases in several measures of cognitive function. They had better episodic memory and processed information more efficiently at the end of the 12 weeks. And they did better on tests that required them to solve problems they had never encountered before, an aptitude called…
