Boswellia for Joint Pain: What the Trials Show

1. What did the trial actually find?

The 2024 trial gave 105 adults aged 40 to 75 one of three things for 90 days. Either 150mg of boswellia extract twice a day, 300mg twice a day, or a dummy capsule. Everyone had early knee osteoarthritis, the wear-and-tear kind. Nobody knew which capsule they had.

• Pain scores fell. The 300mg group dropped 61.9% on the pain scale by day 90, against 45.3% on the lower dose (p<0.001).
• Stiffness and function improved. The combined WOMAC score, which rates pain, stiffness and daily movement, improved 73.6% on the higher dose against 22% on placebo.
• It was slow. Nothing separated the groups at day 5. The gap opened at day 60.
• Side effects were rare. Three people reported mild problems across the whole trial, all settling within a day.

That timing matters. Two weeks of capsules tells you nothing. This is a three-month question.

2. What the trial does not prove

Four things are worth holding on to before you buy anything.

• The makers ran it. Five of the authors were employed by the company that produces the extract. That is disclosed in the paper, and it is a reason to weight the result carefully.
• One product, not an ingredient. The capsules were standardised to 30% AKBA, the boswellic acid the research focuses on. A cheap unstandardised resin is not the same thing.
• The inflammation story did not land. hs-CRP, a blood marker of low-level inflammation, did not differ between the groups. More on that below.
• There is no authorised UK health claim. No boswellia joint claim sits on the GB register. A brand that says it treats arthritis is breaking the rules.

The wider picture is kinder. A 2026 meta-analysis pooled 20 trials and 1,633 people with knee osteoarthritis. Modified boswellia formulations gave the largest improvements in pain, stiffness and knee function.

3. Is your joint pain wear and tear, or something else?

This matters more than the supplement. The trial recruited people with diagnosed knee osteoarthritis. If your joints hurt for another reason, three months of capsules is three months lost.

Osteoarthritis is diagnosed from the pattern, not from bloods. Pain that worsens with use. Morning stiffness of half an hour or less. One or two joints, usually knees or hips.

Other signs point elsewhere. Stiffness lasting well past 30 minutes. Several joints at once. A hot, swollen joint. Pain that eases as you move. Fever, night sweats or weight loss alongside it. Any of those, and you want a GP before a supplement.

The NHS is also blunt about what works best here.

“Exercise is one of the most important treatments for people with osteoarthritis, whatever your age or level of fitness.”

The same NHS page notes that GPs no longer prescribe glucosamine and chondroitin, because the evidence of benefit is not strong enough. Our glucosamine guide goes through that evidence in full.

4. Which marker is worth measuring?

hs-CRP is the one. CRP stands for C-reactive protein, a substance your liver releases when something inflames the body. The hs part means high sensitivity, so the test picks up the low-grade signal that a standard CRP rounds off.

Look at what the trial recorded. Placebo started at 6.46 mg/L and finished at 8.45. The 300mg group started at 11.90 and finished at 8.76. Only that within-group fall reached significance (p=0.018), and the difference between the groups did not.

Two things follow. Boswellia has not been shown to move your hs-CRP. And the three groups started miles apart on it, which is the problem a small trial has and you do not. You have one body and a before number.

• A normal hs-CRP with sore knees fits plain wear and tear. Our CRP guide covers the ranges.
• A raised result suggests something inflammatory is going on and belongs with a GP, not a capsule.
• A full blood count can show the anaemia that often travels with inflammatory arthritis. See the full blood count guide.

Helvy's Advanced Heart Health panel (£159) carries hs-CRP. The General Energy & Wellness panel (£149) carries standard CRP alongside thyroid, vitamin D and B12. Both are home finger-prick tests processed by UKAS-accredited UK laboratories.

The joint pain blood test guide explains how each result is read, and the inflammation guide covers what shifts CRP week to week.

5. How to run this on yourself properly

If the picture fits wear and tear and you want to test the finding, copy the trial rather than guessing at it.

• Score your pain first. Rate it 0 to 10 every morning for a week. Memory makes a poor baseline.
• Get your before number. One hs-CRP reading now gives you something to compare against in three months.
• Match the trial product. That was 300mg twice a day of an extract standardised to 30% AKBA. Check the label for the standardisation, not just the milligrams.
• Give it 90 days. The groups did not separate until day 60. Quitting at week three answers nothing.
• Change one thing. Not boswellia, a new knee routine and a new diet in the same fortnight.
• Keep the exercise either way. It has the strongest evidence behind it.

Two safety notes. Evidence is thin on mixing boswellia with blood thinners, so ask a pharmacist if you take one. Check first if you are pregnant, breastfeeding or on regular medication.

One caveat on the retest. The trial could not show boswellia moving hs-CRP, so we cannot tell you yours will fall. A before and after gives you your own baseline, which is useful whatever you take.
