Osteoarthritis

Do omega-3s reduce osteoarthritis pain?

Reviews disagree. Some pool a small pain or function benefit, while a newer broader pain synthesis did not find a significant osteoarthritis effect.

The question behind the headline

People with osteoarthritis; varied formulations, comparators and pain scales.

What the finding does—and doesn’t—tell us

Symptoms and cartilage preservation are different outcomes. A pooled pain signal does not establish structural joint repair.

Three questions to take forward

  • Was the study population similar to the person or situation I have in mind?
  • Did it measure an outcome people feel or experience, or only a laboratory marker?
  • How do formulation, usual care, absolute benefit and adverse effects change the interpretation?
