Concise Summary of Project:
Study Design: We plan to conduct a parallel-design, randomized, double-blind, placebo-controlled clinical trial to assess cognition, executive function, vision, sleep, immunology, biochemical markers, growth and health in 114 children. Children will be randomized at 12-14 months of age to receive either:
* a micro-encapsulated LCP-supplement that can be sprinkled onto their normal foods from 12 to 36 months of age
* a micro-encapsulated placebo-supplement (containing corn oil) that can be sprinkled onto their normal foods from 12 to 36 months of age
* data will be collected through the age of 42 months

Two foil-packets containing either active intervention or placebo will provide 200mg DHa and 200mg aRa or 400 mg placebo oil per day to the toddler. Two packets of the powders will be added each day to prepared foods.
