Eksperimentel: Docosahexanoic Acid Supplement
In this arm, participants took two different doses of a DHA supplement.
Each dose of the DHA supplement was taken for 4 weeks.
|
The active treatment will consist of Martek's chewable DHA capsules containing 200mg in each capsule. The treatment will be provided as approximately 25mg/kg/day and 35mg/kg/day. These dosages will be divided BID-TID and will be given for 4 weeks.
