Study: Anti-aging Supplements Most Beneficial When Taken Earlier In Life

Results of a new University of Florida College of Medicine study suggest anti-aging supplements are most effective when taken before the onset of old age.
Using an animal model, lead author Christiaan Leeuwenburgh and his colleagues tested a mixture of anti-aging supplements on a group of middle-aged and late-aged subjects. The supplements contained antioxidant coenzyme Q10, creatine and ginseng.
After six weeks, the younger subjects—whose age corresponded to 50-year-old to 65-year-old humans—improved their grip strength by 12 percent and their neurological function by 66 percent compared to a cohort of control group participants.
In contrast, older subjects—whose age was comparable to 65-year-old to 80-year-old men and women—experienced no statistically relevant improvement in physical or cognitive function.
"It is possible that there is a window during which these compounds will work, and if the intervention is given after that time it won’t work," said researcher Jinze Xu.
However, older subjects who were given the supplements did lower their levels of oxidative stress and improve their energy levels.
