300-500mg standardized extract (30-40% AKBA), 2-3x daily (a typical label dose, not the dose used in the cited trials, the one that states its dose gave 100 mg a day of Aflapin, standardized to 20% AKBA)

Standardized extract (30-40% AKBA or 65% boswellic acids)
Supplements commonly provide 99 mg per serving, and food provides more (no cited trial states the dose it used). No upper limit is established, so no maximum is stored. That is not a statement that larger amounts are safe.

Prospective analysis of 237,036 men and 179,068 women in the NIH-AARP Diet and Health Study, plus an updated meta-analysis of cohort studies.
The Cochrane review of oral herbal therapies (PMID 24848732) found high-quality evidence from two trials (85 people) that 100 mg a day of an enriched Boswellia serrata extract for 90 days cut pain by 17 points on a 0 to 100 scale against placebo, with fewer adverse events than placebo in one trial. Effectiveness is that pain reduction. A 250 mg dose of enriched extract showed possible benefit in low-quality evidence from a single small study, so it is plotted flat, not higher. Trials of 100 mg Aflapin a day for 30 and 180 days also reduced knee pain against placebo (PMID 35512759, 39700461). A 999 mg dose of a non-enriched extract is a different product and is not plotted. The Cochrane authors state that the optimal daily dose is still to be determined.
