What is boswellia?
Boswellia is a tree that grows in India and Africa. When the bark is cut, it oozes a resin (tree sap) that's hardened and dried for use. Frankincense, used as a fragrance, comes from this tree.
India's traditional medicine (Ayurveda) has long used it for joints and pain.
Its key active compounds are boswellic acids. Of these, AKBA is known to be the most potent. It blocks the pathway that makes inflammatory substances (leukotrienes), which helps calm long-lasting inflammation.
Boswellia benefits: where it may help
- Joint pain, swelling and stiffness: The most-studied area. It's considered an ingredient that's especially suited to joints.
- Joints in older adults: Widely used for joint discomfort that comes with age.
- Allergies and airways: Some data suggest it may calm an overactive immune response and help with a runny nose, cough and phlegm.
- Gut inflammation: Some studies suggest it may help manage inflammation in the gut.
- Metabolism: There's some data on insulin resistance (when blood sugar stays high even with insulin present) and fatty liver, but it's not as solid as the joint research.
Who it's for / when it's not a good fit
It may help if you:
- Have knee, shoulder or back pain that has lasted 6 months or more
- Have joints that are stiff and swollen in the morning
- Tried curcumin, omega-3 or MSM and wanted more relief
- Have sensitive sinuses or airways
It's not a good fit for:
- Sudden swelling, heat and pain (acute inflammation): This isn't something to manage with supplements. See a doctor.
- People already taking prescription anti-inflammatory pain relievers: Combining them can change how your medication works, so check first.
- People with severe tree or pollen allergies: It's tree sap, so it can cause an allergic reaction.
When to take boswellia and how much
Bottom line: take it after meals. Taken with food — especially food with some fat — it absorbs more than twice as well as on an empty stomach.
| Measure | Daily amount |
|---|---|
| Regular extract | 1,000–1,500 mg |
| Total active compounds (KBA + AKBA) | About 71 mg |
- Many joint combination products contain only a little. Check that it's at single-ingredient levels (about 350 mg a day or more).
- If it upsets your stomach, split the dose and take it after meals.
- Give it a few weeks of steady use to judge the results.
How to choose boswellia: look for AKBA
- Is the AKBA content listed? — Boswellia ingredients vary a lot. A product that lists the % of AKBA, the key active compound, is best.
- Is it a branded extract? — The extracts below are standardized to a consistent amount of active compounds.
| Branded extract | What it is |
|---|---|
| 5-Loxin | Standardized to high AKBA |
| AflaPin | Standardized AKBA, with improved absorption |
| ApresFlex | Patented extract standardized for AKBA |
- Skip candy or chewable "treat" products — Many have no standard for active compounds.
Boswellia side effects and cautions
- Stomach upset: Its acids make heartburn and diarrhea fairly common. Always take it after meals.
- Allergies: It's a tree resin extract, so it can cause allergic reactions like a rash or itching. Stop right away if that happens.
- Blood thinners (antiplatelets): It may raise the risk of bleeding. Talk to your doctor first.
- Anti-inflammatory pain relievers (NSAIDs): The pain-relieving effect may get stronger or weaker. If you take both, work out the dose with your pharmacist or doctor.
Medications and conditions to watch
- Check Antiplatelets (aspirin, clopidogrel, etc.) — May raise the risk of bleeding — talk to your doctor
- Check NSAIDs (ibuprofen, etc.) — The pain-relieving effect may get stronger or weaker — if you take both, check with your doctor and adjust the dose
Combinations
Works well with: Curcumin (Turmeric), Omega-3, MSM (Methylsulfonylmethane)
