Omega-3 Fatty Acid Plasma Levels Before and After Supplementation: Correlations with Mood and Clinical Outcomes in the Omega-3 and Therapy Studies.


ABSTRACT: To examine fatty acid profiles, their response to omega-3 fatty acid (?3) supplementation, and associations with clinical status and treatment response in youth with mood disorders.In a placebo-controlled 2X2 design, 7-14 year-olds (N?=?95) in parallel pilot trials (depression N?=?72; bipolar N?=?23) were randomly assigned to 12 weeks of ?3 supplementation (1.4?g eicosapentaenoic acid [EPA], 0.2?g docosahexaenoic acid [DHA], and 0.27?g other ?3 per day); psychoeducational psychotherapy (PEP); their combination; or placebo (mainly oleic and linoleic acid) alone. Blood was drawn at baseline (N?=?90) and endpoint (n?=?65). Fatty acid levels were expressed as percent of total plasma fatty acids. Correlational and moderator/mediator analyses were done with SPSS Statistics 23.At baseline: (1) DHA correlated negatively with alpha-linolenic acid (ALA) (r?=?-0.23, p?=?0.029); (2) Arachidonic acid (AA, ?6) correlated negatively with global functioning (r?=?-0.24, p?=?0.022); (3) Total ?3 correlated negatively with age (r?=?-0.22, p?=?0.036) and diastolic blood pressure (r?=?-0.31, p?=?0.006). Moderation: Baseline ALA moderated response to ?3 supplementation: ALA levels above the sample mean (lower DHA) predicted significantly better placebo-controlled response (p?=?0.04). Supplementation effects: Compared to placebo, 2?g ?3 per day increased EPA blood levels sevenfold and DHA levels by half (both p?

<h4>Objective</h4>To examine fatty acid profiles, their response to omega-3 fatty acid (Ω3) supplementation, and associations with clinical status and treatment response in youth with mood disorders.<h4>Methods</h4>In a placebo-controlled 2X2 design, 7-14 year-olds (N = 95) in parallel pilot trials (depression N = 72; bipolar N = 23) were randomly assigned to 12 weeks of Ω3 supplementation (1.4 g eicosapentaenoic acid [EPA], 0.2 g docosahexaenoic acid [DHA], and 0.27 g other Ω3 per day); psychoe  ...[more]
