Astaxanthin vs Citrus Bergamot Extract

Mechanism

Astaxanthin spans the entire cell membrane bilayer due to its unique molecular structure (polar end groups with a polyene chain), providing antioxidant protection on both the inner and outer membrane surfaces simultaneously — unlike other carotenoids. It quenches singlet oxygen 6000x more effectively than vitamin C, 800x more than CoQ10, and 550x more than vitamin E. It suppresses NF-kB and modulates Nrf2, reduces oxidative damage to mitochondrial membranes, and protects LDL from oxidation. Uniquely, it crosses the blood-retinal barrier and blood-brain barrier.

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
