Citrus and pomegranate complex supports physical fitness and mental well-being in older adults in recent study
A recent study published in the Journal of Nutrition, Health and Aging1 studied the effects of a citrus and pomegranate complex (Actiful from BioActor BV, based in Maastricht, The Netherlands) on the physical fitness and mental well-being of healthy elderly subjects aged 60-75 years . crossover trial, 36 subjects received either the complex (two 350 mg gelatin capsules) or a placebo daily for four weeks. After a four-week washout period, the intervention was changed for each subject for another four weeks. Subjects completed a grip strength test and a senior fitness test, as well as a quality of life questionnaire (WHO-QOL-100) and gave blood samples before the start and at the end of each four-week intervention period.
The results showed a significant improvement in hand grip strength compared to placebo, as well as a time-treatment interaction on the psychological function domain of the WHO-QOL-100 questionnaire. Researchers separately study the five facets that make up psychological function, including: positive feelings; thinking, learning, memory and concentration; self esteem; body image and appearance; and negative feelings. The results showed that supplementation resulted in a significant temporal treatment effect on thinking, learning, memory, and concentration, compared to placebo. Blood samples also showed significant reductions in malondialdehyde (MDA), a biomarker of oxidative stress, compared to placebo.
