Joints & inflammation
Inflammation isn’t a malfunction. It’s how tissue gets repaired, and it’s supposed to switch off when the job is done. The interesting thing about omega-3 is that it isn’t an anti-inflammatory in the way ibuprofen is — it’s the raw material for the molecules that end inflammation.
Resolution is an active process
Well established
For a long time inflammation was assumed to simply fade out once the triggering signals stopped. It doesn’t. Ending inflammation is a separate, actively driven programme, run by a family of signalling molecules collectively called specialised pro-resolving mediators — resolvins, protectins and maresins.
Your body builds those molecules out of EPA and DHA. There is no other substrate for them. That is the mechanism behind essentially every joint claim made for omega-3: not that it blocks inflammation, but that it supplies the material for switching it off cleanly.
The omega-6 to omega-3 balance
Reasonably supported
Omega-6 fatty acids use the same enzymes as omega-3s, and the molecules they produce tend to be more inflammatory. The two compete for the same machinery, so what matters isn’t only how much omega-3 you get but how it compares with your omega-6 intake. Modern diets, heavy in seed oils and processed food, have shifted that ratio dramatically compared with the diets humans evolved on.
Raising omega-3 intake shifts the balance back. That is a slow structural change rather than a switch you flip — it is membrane composition changing over weeks.
What the trials found
Reasonably supported
Controlled trials of omega-3 in people with joint discomfort have generally reported modest improvements in reported stiffness and in the use of over-the-counter pain relief, rather than dramatic changes. Trials in rheumatoid arthritis — an autoimmune condition, treated medically — have been more consistently positive than trials in wear-and-tear joint discomfort, which are mixed.
Some small studies have specifically tested krill oil and reported reductions in inflammatory markers and self-reported stiffness. These studies are generally small, several have been industry-funded, and the field would benefit from larger independent replication. We think that’s worth saying on our own product page.
Astaxanthin’s part in it
Early or mixed
Astaxanthin is a strong antioxidant in laboratory testing, and it’s frequently credited with anti-inflammatory effects in krill oil marketing. The honest position is that the amount in a krill oil softgel is small — 100 mcg in ours — compared with the doses used in astaxanthin studies, which are typically measured in milligrams.
Its clearest job at this dose is protecting the oil itself from oxidation, which matters: rancid omega-3 is worse than no omega-3. Treat any claim about astaxanthin’s systemic effects at these levels as unproven.
Setting expectations
If you have significant joint pain, omega-3 is not the answer on its own, and a supplement page shouldn’t pretend otherwise. What the evidence supports is that adequate omega-3 intake supports the body’s normal inflammatory-resolution processes. That’s a foundation, alongside movement, weight management and whatever your doctor is treating you for — not a replacement for any of them.
