DOUBLE-BLIND, RANDOMISED, PLACEBO-CONTROLLED PILOT TRIAL Tier 3 2026

In a 40-person pilot, krill oil raised the omega-3 index; pain findings were exploratory and not definitive.

En 12-veckors dubbelblind randomiserad placebokontrollerad pilotstudie med 40 vuxna visade att krillolja höjde omega-3-indexet. Smärtlindring kunde inte bekräftas signifikant. The primär outcomes were feasibility measures rather than pain relief.

Recruitment targets were met within 8 months. Retention was 95%, adherence exceeded 70% in both groups, and acceptability averaged 7.7 out of 10. Krill oil increased the omega-3 index from 4.3% to 7.4%; the placebo group had no meaningful change. Pain outcomes were exploratory. The abstract reports trends favouring krill oil for pain intensity, fewer pain sites and global improvement. The reduction in pain sites had a rate ratio of 0.59, with a 95% confidence interval from 0.41 to 0.84. The global-improvement odds ratio was 4.35, but its 95% confidence interval, 0.97 to 19.55, included no effect. No serious adverse events occurred.

This trial shows that the regimen was feasible and altered omega-3 status. It was not powered as a definitive pain-efficacy study, and it says nothing about longevity.

Krill oil supplementation was feasible and acceptable in older US adults with chronic musculoskeletal pain, supporting a fully powered pain trial.
Kritikernoter

Only 40 participants were studied for 12 weeks, and feasibility was the primär outcome. The pain results were exploratory, while the global-improvement confidence interval included no effect.
