Rating breakdown

Quercetin and bromelain have solid data on mast cell stabilization and respiratory complaints.

Thorne avoids magnesium stearate and uses hypoallergenic raw materials.

NSF Certified for Sport including a full contaminant panel.

Product Description

Quercenase combines 250 mg quercetin with bromelain per capsule. Bromelain reportedly enhances absorption and provides additional anti-inflammatory effects.

What We Like

  • NSF-certified manufacturing
  • Bromelain supports absorption and digestion
  • Only two excipients (hypromellose, silicon dioxide)

What We’re Missing

  • Hard capsules are relatively large
  • Noticeably more expensive than single-ingredient products
  • Bromelain can taste bitter if capsules are opened

Usage Recommendation

2 capsules daily with meals, or 1 capsule three times daily as needed. Always take with food if stomach-sensitive.

Ingredient dossier

Quercetin is a plant flavonoid with antioxidant and senolytic potential. Human senolytic evidence is limited to tiny pilot studies using Dasatinib+Quercetin combined — not quercetin alone.
