Note, despite the conclusion "neither vitamin D nor n-3 FA supplementation over 1 year decreased these biomarkers of inflammation", there is this bit in the actual article: "Among individuals who had <1.5 servings of fish per week at baseline, active n-3 FA was associated with a decline in hsCRP of 10.45% (95% CI, -20.44% to 0.79%)"
So for those of us who do not eat fish, compensating that with supplements might make sense still.
The article also mentions some other benefits of the supplements, beyond controlling inflammation:
> Participants with normal body mass index (BMI <25 mg/kg²) randomized to active vs placebo vitamin D showed a significant reduction in invasive cancers
> Cardiovascular disease events were significantly lower for active vs placebo n-3 FA among individuals who consumed <1.5 fish servings/week. Additionally, n-3 FA supplementation reduced risk of myocardial infarction
