Boswellia Serrata 65% Extract

Description

Boswellia serrata gum resin extract, standardised to 65 percent boswellic acids, with the AKBA fraction listed separately rather than folded into the total. This is the resin English speakers call frankincense, tapped from the trunk of the tree. A boswellia serrata label that gives only a total percentage has left out the number most of the research is about, which is the reason both appear here.

What is on the panel

Why the AKBA number matters more than the 65 percent

Boswellic acids are a family, not a single compound, and they are not equally represented in a resin extract. AKBA is usually a minor member, often in the low single percentage points of a standard extract, and it is the one the pharmacological literature concentrates on. A 65 percent total can therefore sit alongside an AKBA figure of 2 percent or of 20, and only one of those is an enriched product.

Enriched extracts are sold at lower weights because of that, which makes milligram comparisons between two boswellia serrata bottles meaningless without both numbers. Extract ratio, plant part and marker percentage are the three figures the herbals page insists on, and here there are two markers rather than one.

What the trials administered

Published studies have used standard extracts at roughly 300 to 400 mg three times daily, and AKBA enriched extracts at 100 to 250 mg a day, over 8 to 12 weeks. The endpoints recorded were WOMAC joint scores, pain visual analogue scales, walking distance and joint swelling counts in osteoarthritis protocols.

That is a description of the doses given and the instruments read in the literature, nothing more. It is not a claim about this bottle. The percentages are on the panel so a published protocol and a product label can be compared without an exchange of emails.

Boswellia serrata against turmeric, since the question comes up

Different plants, different marker compounds, different literatures, and they are frequently sold together at amounts neither study used. Curcuminoids are measured as a percentage of a turmeric extract. Boswellic acids are measured as a percentage of a boswellia serrata resin extract. A combination capsule listing one blend total for both has removed the figures that let you check either. The curcumin options on the joint and bone page state their percentages separately.

Why a boswellia serrata serving is often several capsules

Because the studied amounts run towards a gram of extract a day and a capsule holds a few hundred milligrams. Units per serving and servings per container sit next to each other on the listing for that reason, since a 120 count bottle at four capsules a serving is a month rather than four months. That one piece of arithmetic changes the real price of half of this category.

Resin, and why the format is sticky

Gum resin extract is tacky and aromatic, which is why it is sold in capsules rather than loose powder and why it clumps if a bottle is left open in a warm room. The smell is the resin and not a fault. Keep the lid closed and the desiccant in place.

Species substitution, the real risk

Boswellia carterii, papyrifera and sacra are traded as frankincense too, at different prices and with different acid profiles, and milled resin gives no visual clue which tree it came from. Identity testing on every lot is the only way that question gets answered, which is why the four seals article treats identity as separate from potency.

Testing

Every lot of boswellia serrata extract goes to an independent laboratory, which confirms species, measures total boswellic acids and the AKBA fraction, and screens heavy metals, pesticides and microbials on every lot. Failing material is withdrawn and the report stays published. The rest of this shelf is on the joint and bone page, with a free government summary of the plant literature at the NCCIH herbs at a glance series.
