A double-blind, randomized clinical trial of dietary supplementation on cognitive and immune functioning in healthy older adults.

ABSTRACT:

Background

Declining cognitive function is relatively common and increasingly prevalent. Studies have shown that different nutrients (e.g., Ginkgo biloba and vitamin E) appear to be effective at improving memory and concentration, while less is known about their effect on immunity.

Methods

This study investigated the effect of Ginkgo Synergy(®) plus Choline (n = 33) and OPC Synergy(®) plus Catalyn(®) (n = 31) versus placebo (n = 33) in a 6-month, randomized, double-blind trial on cognitive and immune functioning among English-speaking, non-smoking, healthy older adults. The Stroop Color and Word Test, Trail Making Test A and B, Controlled Oral Word Association, Hopkins Verbal Learning, Mini-Mental State Exam, and Digit Symbol were administered at baseline and 3 and 6 months
