Citrus Bergamot Extract vs Glucosamine + Chondroitin

Mechanism

Contains brutieridin and melitidin — statin-like HMG-CoA reductase inhibitors from bergamot orange. Activates AMPK, improves lipid profiles (reduces LDL, increases HDL), and has antioxidant effects. Supports cardiovascular and metabolic health.

Contraindications

• Rhabdomyolysis risk if combined with high-dose statins without monitoring

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
