Official title
A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Effects of DHA on Cognitive Functions in Preschool Children
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of this study is to determine whether a 4-month period of supplementation with 400 mg/day of docosahexaenoic acid (DHA) provided from chewable softgel capsules containing bubblegum flavored microalgal oil (DHASCO-S) versus placebo improves one or more cognitive measures of attention, memory, processing speed, and error rate in healthy children 4 years of age. The secondary objectives are to measure the safety and tolerability of the DHA dose administered and to measure blood DHA levels before and after supplementation.
