Bromelain

Supplements

Mechanism

Proteolytic enzyme complex from pineapple stems. Anti-inflammatory via modulation of prostaglandin synthesis, fibrinolytic, and anti-edematous. Degrades fibrin and reduces blood viscosity. Enhances absorption of other supplements (particularly quercetin and curcumin).

Contraindications

  • Pineapple allergy
  • Pre-surgery (bleeding risk)
  • Active bleeding

Mechanism

Stable precursor to sulforaphane. Requires myrosinase enzyme (from gut bacteria or co-administered) for conversion. Provides sustained sulforaphane release compared to direct supplementation. Activates Nrf2 pathway for antioxidant and detoxification gene expression.

Contraindications

  • Thyroid conditions (goitrogen at very high doses)
