Benefits of Astaxanthin

Evidence-Based Benefits

• Extraordinary antioxidant potency — astaxanthin quenches singlet oxygen 6,000 times more effectively than vitamin C and 550 times more than vitamin E in laboratory assays; importantly, it never becomes a pro-oxidant (Naguib, 2000)
• Skin protection — Tominaga et al. (2012) showed 6mg astaxanthin daily for 6-8 weeks reduced crow's feet wrinkles, improved skin elasticity, and decreased age spot size in a double-blind RCT of UV-exposed women
• Exercise performance — Earnest et al. (2011) found 4mg astaxanthin daily for 28 days improved cycling time trial performance and power output in trained cyclists
• Cardiovascular support — astaxanthin reduces LDL oxidation, improves blood lipid profiles, and enhances blood flow; Yoshida et al. (2010) showed reduced triglycerides and increased HDL in overweight subjects
• Eye health — astaxanthin crosses the blood-retinal barrier and reduces eye fatigue and accommodative dysfunction in VDT (visual display terminal) workers, supporting visual acuity and retinal protection

What the Research Says

Astaxanthin research is well-developed for a carotenoid supplement. Naguib (2000) established its extraordinary antioxidant potency in comparative assays. Tominaga et al. (2012) published the strongest human trial for skin benefits, demonstrating wrinkle reduction and elasticity improvement. Earnest et al. (2011) showed exercise performance benefits. Yoshida et al. (2010) confirmed cardiovascular biomarker improvements. The AstaReal brand from Japan has sponsored much of the clinical research. Astaxanthin's unique molecular structure allows it to span the cell membrane bilayer, providing protection on both sides — a property not shared by any other dietary antioxidant. Natural algal astaxanthin is 20-50x more potent than synthetic astaxanthin in free radical scavenging.
