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

Glucosamine serves as a substrate for glycosaminoglycan (GAG) and proteoglycan biosynthesis in articular cartilage. It stimulates chondrocyte production of type II collagen and proteoglycans while inhibiting MMP-3 and aggrecanase enzymes that degrade cartilage matrix. Chondroitin sulfate provides osmotic swelling pressure in cartilage (water retention), inhibits complement-mediated inflammation, and downregulates NF-kB and IL-1beta in synoviocytes. Together they exert synergistic chondroprotective and mild anti-inflammatory effects.

Standard Dosing

1500mg glucosamine sulfate + 1200mg chondroitin sulfate daily

Timing

With meals, split into 2-3 doses. Full clinical benefit requires 8-12 weeks of consistent use.

Cycle Duration

ongoing (minimum 3 months to assess response)

Side Effects

  • GI upset/nausea
  • Heartburn
  • Diarrhea or constipation
  • Drowsiness (rare)
  • Headache

Contraindications

  • Shellfish allergy (if shellfish-derived glucosamine — use vegetarian/fungal source)
  • Active bleeding with anticoagulant therapy
