Does fish oil reduce joint inflammation?

The first kind of inflamed joint, autoimmune synovitis, and the file fish oil has there

Does fish oil reduce joint inflammation is a question whose answer depends entirely on which of two kinds of inflamed joint the reader has, because the two are different diseases with different files, and the shelf sells the first kind's file to the second kind's reader. The first kind is autoimmune synovitis: in rheumatoid arthritis and its relatives, psoriatic and other inflammatory arthritides, the immune system attacks the synovium, the joint's lining, flooding it with immune cells and the signalling molecules they make, so the joint swells, is hot, stiff for an hour or more in the morning, and is attacked symmetrically, both hands, both wrists, both feet, a diagnosis a rheumatologist makes on blood tests, imaging and the pattern, and one whose inflammation is the immune kind that omega-3's resolving mediators act on. The file here is real and modest: the meta-analyses of fish oil in rheumatoid arthritis pool randomised trials at around 2.7 grams of EPA and DHA a day or more, nine standard softgels or a concentrate, taken for at least three months alongside the standard treatment, and report modest reductions in tender joint count, in the duration of morning stiffness and in the use of painkillers, the rheumatoid arthritis and fish oil literature's finding, an adjunct effect that some rheumatology guidance mentions and that no register claim covers, since no supplement may claim to reduce inflammation. So for the first kind of joint the answer is a modest research yes, at a high rung, over months, with a rheumatologist knowing and the disease-modifying treatment doing the work, the fish oil sitting alongside it rather than replacing it, which is the four-joints pages' one real entry.

The second kind of inflamed joint, mechanical and loaded, the null trials, telling the two apart, and the joints filed

The second kind of inflamed joint is the one a lifter has: the low-grade, mechanical inflammation of an osteoarthritic joint, where cartilage has worn and the lining is mildly irritated by the wear, of an overused joint, a tendon insertion or a joint capsule irritated by volume, or of a barbell-loaded joint, a knee in the squat, a shoulder in the press, an elbow at the bench, sore from load and not from an immune attack, and here the trials are null. The best test is the osteoarthritis one, a two-year randomised trial comparing high-dose with low-dose fish oil in knee osteoarthritis that found no advantage for the high dose on pain or function, and the wider osteoarthritis literature finds nothing reliable at any dose, the osteoarthritis and fish oil literature's verdict, while for an overused or loaded joint there is no trial at all, because the question has never been thought worth asking, the inflammation there being a response to load that resolves when the load is managed and that omega-3's mediators have no immune attack to resolve. So for the second kind of joint the answer is no, and the route is the mechanic's: load management, a deload settling most loaded-joint pain in a fortnight, technique, a physiotherapist for a joint that persists, and a GP for a joint that swells, locks, is hot or is stiff for an hour in the morning, since that last pattern is the first kind of joint announcing itself and deserves a rheumatologist's look rather than a shelf. Telling the two apart is the practical skill: morning stiffness lasting an hour or more, symmetry, warmth and swelling, fatigue and a joint that hurts at rest point to the immune kind and to a GP; pain that follows load, eases with rest and a deload, sits in the joints a programme stresses and is stiff for minutes rather than an hour points to the mechanical kind and to a physiotherapist. The register has no joint claim for omega-3 in either direction, and the joint claims that exist belong to vitamin C for collagen and to nothing for inflammation. The joints filed: autoimmune synovitis with a modest research adjunct at 2.7 grams for months under a rheumatologist, mechanical, osteoarthritic and loaded joints with null trials and a physiotherapist, the pattern that tells them apart, and the worked example being a standard oil for the audit, £14.99 for 90 at 17p.

The verdict, a modest adjunct for an immune attack on the lining and nothing for a joint that is simply worn or loaded

Does fish oil reduce joint inflammation: for the first kind of inflamed joint, the autoimmune synovitis of rheumatoid arthritis and its relatives in which the immune system attacks the lining, modestly, at around 2.7 grams of EPA and DHA a day or more for at least three months alongside a rheumatologist's treatment, reducing tender joint count, morning stiffness and painkiller use in the meta-analyses as a research adjunct with no claim, and for the second kind, the low-grade mechanical inflammation of an osteoarthritic, overused or barbell-loaded joint, not at all, the two-year knee osteoarthritis trial finding no advantage for high-dose fish oil and a lifter's loaded joint belonging to a deload, technique and a physiotherapist, with morning stiffness of an hour, symmetry and warmth being the pattern that sends the second reader to a GP for the first diagnosis. A standard oil for the audit: Futuro Labs Omega 3 Fish Oil, one with food, 180mg EPA and 120mg DHA, 90 for £14.99 at 17p a day.

Questions people also ask

Does fish oil help rheumatoid arthritis?

Modestly, as an adjunct: meta-analyses of randomised trials at around 2.7 grams of EPA and DHA a day or more for at least three months alongside standard treatment report modest reductions in tender joint count, morning stiffness and painkiller use, a research finding with no claim that sits beside the disease-modifying treatment with the rheumatologist knowing.

Does fish oil help osteoarthritis?

No reliably: a two-year randomised trial comparing high-dose with low-dose fish oil in knee osteoarthritis found no advantage for the high dose on pain or function, and the wider osteoarthritis literature finds nothing consistent at any dose, the inflammation in a worn joint being mechanical rather than the immune attack omega-3's mediators act on.

Will fish oil help my sore knees or shoulders from lifting?

No: a barbell-loaded joint is sore from load and not from an immune attack, there is no trial of fish oil for it and no reason to expect one, and the route is a deload, which settles most loaded-joint pain in a fortnight, technique and a physiotherapist for a joint that persists.

How can I tell if my joint pain is inflammatory arthritis?

By the pattern: morning stiffness lasting an hour or more, symmetry across both hands, wrists or feet, warmth and swelling, fatigue and pain at rest point to the immune kind and to a GP and a rheumatologist, while pain that follows load, eases with rest and a deload and is stiff for minutes points to the mechanical kind and to a physiotherapist.

How much fish oil for joint inflammation?

For the immune kind only, around 2.7 grams of EPA and DHA a day, nine standard softgels or a concentrate, for at least three months with a rheumatologist knowing, and for the mechanical kind no dose, since the trials are null and a loaded joint is managed by load, with a standard softgel taken for the heart claim by the oily-fish audit as for anyone.
