Bioavailability
Astaxanthin is not soluble in water, therefore, its bioavailability is low and is determined by several factors,
the most prominent one being its level of esterification. When it is esterified (bound to fat), or when taken
with oil, Astaxanthin is readily absorbed in the digestive system and displays higher bioavailabilty (Odberg
2003, Rufer 2008, Barbossa 1999, Okada 2009). Other factors influencing its bioavailability include its level
of oxidation, its chemical structure, the method (Mendes-Pinto 2001) and source (Bowen 1999) of industrial
production, and additional dietary factors such as the presence of other carotenoids and smoking (Okada
2009).
