How much fish oil to help with joint pain?

The short answer

The honest dose is the literature's: the meta-analysis finding reduced pain and stiffness in inflammatory arthritis used around 2.7 to 4 grams of EPA and DHA a day for at least three months, a concentrate rather than a standard softgel. In knee osteoarthritis a two-year trial found high-dose fish oil no better than low-dose. No UK joint claim exists. A lifter's joint pain from load, tendons or wear is neither condition.

  • Inflammatory arthritisaround 2.7 to 4 grams of EPA and DHA a day for three months or more: reduced pain, stiffness and tender joints
  • Osteoarthritisa two-year trial: high-dose fish oil no better than low-dose on pain or function
  • The claimnone for joints; the register's omega-3 sentences are heart, brain, vision, triglycerides and blood pressure
  • A lifter's joint painload, tendons, wear: no dose of fish oil treats it

The dose the literature actually used, in two conditions, and what it means in softgels

How much fish oil to help joint pain has an honest answer only if the joint is named, because the literature that found an effect studied one condition at a dose few readers take and found nothing in a second condition at any dose. Inflammatory arthritis: the meta-analysis of randomised trials, mostly in rheumatoid arthritis, found reduced joint pain, shorter morning stiffness and fewer tender joints with omega-3 supplementation against placebo, the trials using around 2.7 to 4 grams of EPA and DHA a day for at least three months, which in softgels is nine to thirteen standard 300mg softgels or three to four concentrate softgels a day, every day, for a quarter of a year, a dose that is a concentrate's and a commitment that is a patient's, in a condition diagnosed and treated by a rheumatologist with medicines the fish oil sat beside rather than replaced. Osteoarthritis: the wear-related joint pain most readers over forty mean, and here the file is weak, a two-year randomised trial comparing high-dose with low-dose fish oil in knee osteoarthritis finding no advantage for the high dose on pain or function, and reviews rating the osteoarthritis evidence poor against the inflammatory file, so a reader with a worn knee has no dose at which fish oil has been shown to help it. The register agrees with the weakness of both: omega-3 holds no joint claim in the UK, its sentences being heart, brain, vision, triglycerides and blood pressure, so a fish oil sold for joints has stepped outside the register whatever dose it suggests.

A lifter's joint pain, which is neither condition, the honest use of fish oil, and the dose filed

A lifter's joint pain is usually neither condition, and that is the page's most useful line: knees, elbows, shoulders and hips that hurt in a lifter are usually load that outran a joint's tolerance, tendinopathy at an insertion that warms up and then worsens, or early wear, each with its own route, load management and a deload, a physiotherapist for tendons, strength work and weight for wear, and a GP for the inflammatory signs, a hot swollen joint, morning stiffness lasting over an hour or symmetrical swelling, that would move the pain into the condition the literature studied. No dose of fish oil treats a tendon, a loaded joint or a worn one, and a reader who takes four grams a day for three months for a lifter's elbow has taken a rheumatoid dose for a tendon and will find the elbow answered by the physiotherapist they saw in month two. The honest use of fish oil for a lifter with joint pain is the same as for any lifter: one standard softgel for the 250mg heart claim if oily fish is not eaten twice a week, or a concentrate for the gram of the omega-3 index research, taken for those reasons and not for the joint, with the note that a reader whose GP has diagnosed inflammatory arthritis and who wants to try the literature's dose alongside treatment does so with the rheumatologist's knowledge, at two to four grams from a concentrate for three months, judged on pain and stiffness and not expected to replace anything. The dose filed: several grams of EPA and DHA a day for three months or more in inflammatory arthritis, no advantage for a high dose in osteoarthritis, no UK joint claim, and no dose for a lifter's load, tendon or wear pain, with the worked example being omega-3 for the claims it holds, one softgel at 17p, £14.99 for 90.

The verdict, a rheumatoid dose for a rheumatoid condition, and nothing for the rest

How much fish oil to help with joint pain: the dose the literature used, around 2.7 to 4 grams of EPA and DHA a day for three months or more in inflammatory arthritis, a concentrate's dose taken alongside a rheumatologist's treatment, with a two-year osteoarthritis trial finding high-dose fish oil no better than low-dose, no UK joint claim for omega-3 at any dose, and a lifter's joint pain from load, tendons or wear being neither condition and treated by load management, a physiotherapist, strength work and a GP for inflammatory signs rather than by any softgel count. Omega-3 for the claims it holds: Futuro Labs Omega 3 Fish Oil, one softgel, 180mg EPA and 120mg DHA, 90 for £14.99 at 17p a day, not for joints.

What to check on the label

  • Name the joint condition first: inflammatory, wear, or a lifter's.
  • Know the inflammatory dose: several grams for three months, with a rheumatologist.
  • Know the osteoarthritis result: high dose no better than low.
  • Expect no dose for a lifter's joint: load, a physio, a GP.
  • Take omega-3 for its own claims: heart at 250mg, not joints.

Questions people also ask

How much omega-3 per day for joint pain?

In the inflammatory arthritis trials that found reduced pain and stiffness, around 2.7 to 4 grams of EPA and DHA a day for at least three months, three to four concentrate softgels daily alongside a rheumatologist's treatment; no dose has been shown to help osteoarthritis or a lifter's load-related joint pain.

Does fish oil help knee pain?

Not on the trials for wear-related knee pain: a two-year randomised trial in knee osteoarthritis found high-dose fish oil no better than low-dose on pain or function, and reviews rate the osteoarthritis file weak, so a worn knee is helped by strength work, weight and a GP rather than a dose.

Can a fish oil supplement claim to help joints in the UK?

No: omega-3's authorised sentences are heart function, brain function, vision, blood triglycerides and blood pressure, with no joint claim, so a fish oil sold for joints has stepped outside the register whatever dose it suggests.

My elbow hurts from lifting, will fish oil help?

No: a lifter's elbow is usually tendinopathy at an insertion that warms up and then worsens, a physiotherapist's problem with load management as the fix, and no dose of fish oil treats a tendon, the inflammatory file being about a different disease.

How many fish oil capsules equal the arthritis dose?

Around nine to thirteen standard 300mg softgels or three to four concentrate softgels a day, every day, for three months or more, which is why the trials used concentrates and why the dose is a patient's commitment made with a rheumatologist's knowledge.
