Mechanism of Action

In vitro	Astaxaxanthin is a carotenoid nutrient with molecular properties that precisely position it within cell membranes and circulating lipoproteins, thereby imbuing them with potent antioxidant and anti-inflammatory actions. This compound also effectively protects the double membrane system of mitochondria, to the point of boosting their energy production efficiency. In cultured cells, it protects the mitochondria against endogenous oxygen radicals, conserves their redox (antioxidant) capacity, and enhances their energy production efficiency. It has also protected human LDL against oxidative attack. This chemical specifically protects the mitochondria of cultured nerve cells against toxic attack and stimulates the proliferation of cultured nerve stem cells. It effectively protects cultured nerve cells against hydrogen peroxide toxicity, and down-regulates genes linked to cell death and up-regulates genes linked to cell survival.
In vivo	In pharmacokinetic studies, after ingestion of esterified natural astaxanthin, only unesterified astaxanthin appears in the blood. This compound's bioavailability is substantially affected by meal timing and by smoking. Supplementation with this chemical may lower lipid peroxidation in vivo. It significantly improves the memory performance of mice in the Morris water maze. It has demonstrated safety in numerous human clinical trials. The doses of this compound used in clinical trials have ranged from 1 mg/day to 40 mg/day (with the majority in the 6-12 mg range); single-dose pharmacokinetic studies use up to 100 mg per dose.
