Boswellia serrata (AKBA)
Frankincense extract. Inhibits 5-LOX (a different inflammation pathway than NSAIDs target), making it especially useful for joint pain and inflammatory bowel disease.
Strong for knee osteoarthritis pain and function (multiple RCTs show effects comparable to NSAIDs with better safety profile — works within 7 days for AprèsFlex). Moderate for ulcerative colitis remission, Crohn's, asthma. Effects: days-weeks for pain; 8+ weeks for IBD.
Boswellia serrata is the Indian variety of the same frankincense tree used in incense for 3,000 years. Its bioactive boswellic acids — especially AKBA (acetyl-11-keto-β-boswellic acid) — selectively inhibit 5-lipoxygenase, an inflammatory enzyme that NSAIDs and steroids don't touch. This gives boswellia a different mechanism than most anti-inflammatories, complementary to ibuprofen / curcumin / fish oil. Best evidence: knee osteoarthritis (comparable to NSAIDs in head-to-head trials), inflammatory bowel disease (ulcerative colitis, Crohn's), and asthma. Often combined with curcumin in joint formulas.
- Form
- AprèsFlex / AflapIN (standardised to 20% AKBA) — most-studied bioavailable form. 5-Loxin (30% AKBA) — also clinically supported. Plain boswellia 65% — older, less concentrated.
- Dose
- 100–250 mg/day of AprèsFlex / 5-Loxin. 300–500 mg 2–3x daily of standard 65% extract.
- Timing
- With food. AM and PM split for higher doses.
- Schedule
- Daily, ongoing.
- Side effects
- Generally well-tolerated. GI upset, nausea, mild diarrhea. Rare skin rash.
- Interactions
- NSAIDs — additive (helpful for pain, but combined GI risk). Immunosuppressants — mild interaction (boswellia is mildly immune-modulating).
- Contraindications
- Pregnancy (may stimulate menstruation). Active IBD flare without provider input.
- Lab markers
- Not standard. CRP, ESR for inflammation tracking.
- Food sources
- Frankincense resin is traditionally chewed in some cultures but isn't part of typical diet.
Pairs with
Curcumin (classic joint-pain pairing — synergistic at different inflammation pathways). Omega-3 fish oil (covers more inflammatory pathways). Glucosamine + chondroitin / UC-II for full joint stack.
