Astaxanthin increases strength and endurance.
- Astaxanthin seems to improve the immune system by increasing the number of antibody producing cells. Astaxanthin enhances antibody production by exerting actions on T-cells and T-helper cells. Astaxanthin is used to treat neurodegenerative conditions such as Alzheimer’s and Parkinson?s disease.
- Astaxanthin protects the eyes and skin from sun radiation damage by quenching singlet and triplet oxygen. Studies with rats show that astaxanthin reduces retinal injury.
- Studies have shown the anti-cancer effects of astaxanthin in rodents. The inhibitory effect of astaxanthin on cancer is stronger han that of beta-carotene.

Toxicity and symptoms of high intake Astaxanthin
Astaxanthin is practically non-toxic in acute animal studies at doses up to 18 grams. When tested for genotoxicity, there was no evidence for mutagenicity in Ames/Salmonella assays nor did it induce micronuclei when tested in vivo up to 2000 mg/kg in mice. There was no maternal, embryo-toxic or teratogenic effects in a teratology study in rabbits given up to 400 mg/kg over most of the gestational period.
No adverse effects were noted in a one-generation reproduction study at doses up to 400 mg/kg in rats. In multiple subchronic feeding studies in rats, astaxanthin did not produce any adverse toxicological effects.
