Citrus Bergamot Extract vs Sulforaphane (Broccoli Seed Extract)

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

Sulforaphane is the most potent natural activator of the Nrf2-ARE (antioxidant response element) pathway. It modifies Keap1 cysteine residues, releasing Nrf2 to translocate to the nucleus and upregulate >200 cytoprotective genes including NQO1, glutathione S-transferases, heme oxygenase-1, and UDP-glucuronosyltransferases (Phase II detox enzymes). It also inhibits HDAC activity (epigenetic modification), induces Phase II/III xenobiotic metabolism, and suppresses NF-kB inflammatory signaling.

Standard Dosing

10-30mg sulforaphane daily (equivalent to ~100-200mg broccoli seed extract standardized to glucoraphanin + myrosinase)

Timing

On empty stomach or with light meal. Myrosinase enzyme required for conversion from glucoraphanin — ensure supplement contains it or add mustard seed powder.

Cycle Duration

ongoing

Side Effects

• Gas/bloating
• Mild GI discomfort
• Thyroid concerns at very high doses in iodine-depleted individuals

Contraindications

• Hypothyroidism with iodine deficiency (goitrogenic potential)
• Pregnancy (insufficient high-dose data)
