Double Wood Quercetin with Bromelain Review
#5 of 9 · Highest Purity Combo✓ Label verified · Supplement Facts read Sep 7, 2026Real retailer photo, cut out. Label unedited.
Consider it. Best-spec plain combo, same absorption ceiling. If you want the highest purity and bromelain content in an unenhanced combo from a COA-transparent seller, Double Wood is it.

Why It Scores 6.6 — And The Label Line Behind Each Number
Form & Bioavailability
35% of scoreHigher purity than typical budget extracts, but still an unenhanced quercetin, so absorption remains low. Purity improves what's in the cap, not how much reaches your blood.
- Form
- 96% purified quercetin + bromelain, capsule
Third-Party Testing & Purity
20% of scoreStates 96% purity, third-party tested, vegan-safe, gluten-free, with COAs available from a single-SKU seller. Good transparency for the price band.
- Testing
- Third-party tested, COAs available
Dose vs Clinical Range
20% of score1,000 mg quercetin per two-cap serving matches the top of the studied range, with the highest bromelain co-dose (200 mg) in the set.
- Dose
- 1,000 mg quercetin + 200 mg bromelain per 2-cap serving
Tolerability & Safety
10% of scoreWell tolerated; higher bromelain content means the usual blood-thinner and pineapple-allergy cautions apply a bit more. Large two-cap serving.
Value
15% of score~$25 for 60 servings is fair but not category-leading; you pay a small premium for the purity claim and COA transparency over Nutricost.
- Count
- 120 capsules (60 servings)
- Cost per dose
- ~$0.42 per 2-cap serving (~$25/60)
- More Specs
- Standardization
- Stated 96% quercetin purity

Marketing Claims Vs. Reality
96% purity means better results than lower-purity quercetin
Higher purity improves label accuracy but is not shown to improve clinical outcomes; the binding constraint for plain quercetin is absorption, not the small purity difference.
The product provides 1,000 mg quercetin per capsule
Per the label the 1,000 mg is a two-capsule serving, not per capsule; each cap carries roughly 500 mg quercetin.
What Our Test Actually Found
Transparency is the genuine differentiator
Publishing COAs and a specific purity figure from a single-brand seller is more accountability than many competitors offer, and it's a legitimate reason to prefer Double Wood within the plain-combo tier.
Purity and absorption are different problems
A cleaner extract still needs a delivery system to be absorbed well. The 96% figure is a quality signal, not a bioavailability upgrade, so this stays mid-pack behind the phytosomes.
Full analysis: all pros & cons (7), buy if / skip if
- Stated 96% purity, above typical budget extracts
- Highest bromelain pairing in the set (200 mg)
- COA-transparent single-brand seller
- Full 1,000 mg quercetin per serving
- Still unenhanced quercetin, so absorption is low
- 1,000 mg is a two-cap serving, not per cap
- Mid-pack value versus Nutricost's cheaper per-gram
- Stated 96% purity, above typical budget extracts
- Highest bromelain pairing in the set (200 mg)
- COA-transparent single-brand seller
- Still unenhanced quercetin, so absorption is low
- 1,000 mg is a two-cap serving, not per cap
- Mid-pack value versus Nutricost's cheaper per-gram
If you want the highest purity and bromelain content in an unenhanced combo from a COA-transparent seller, Double Wood is it. Just don't mistake 96% purity for bioavailability; a phytosome still delivers more usable quercetin.
Double Wood leans on transparency: stated 96% quercetin purity (above the ~70-90% typical of budget extracts), the highest bromelain pairing here at 200 mg, and published COAs. It's a 1,000 mg quercetin plus 200 mg bromelain two-cap serving. On paper it's the strongest plain combo. In practice it shares the category's ceiling, since even purified quercetin isn't well absorbed without a delivery system.
The spec sheet leader among plain combos
Double Wood is the pick if purity and transparency top your list and you want the highest bromelain co-dose. It earns a solid mid-tier spot, but purity doesn't defeat quercetin's absorption problem, so it lands behind the phytosomes and the cheaper tested combos.
If This Doesn’t Fit — Try These
04Nutricost Quercetin + Bromelain
Nutricost is the pick if you want the highest plain-quercetin dose per dollar with a lab test attached.
02Thorne Quercetin Phytosome
If you want the most trustworthy label on the shelf and cost is no object, Thorne is the pick.
Quick Answers
Does 96% purity make it worth more?
It's a real quality signal and above many budget extracts, but purity doesn't fix absorption, so it won't outperform a phytosome on effective delivery.
Is the 200 mg bromelain a real advantage?
It's the highest bromelain dose here, useful if you want the enzyme for anti-inflammatory/allergy support, though the quercetin-absorption benefit of bromelain remains unproven in humans.
