Bestcare - Astaxanthin: the world's best kept health secret

Astaxanthin, the King of Carotenoids, is a carotenoid compound that is closely related to the better known beta carotene but exhibits superior antioxidant properties. Currently, the primary natural source for astaxanthin is the microalgae Haematococcus Pluvialis. It seems to accumulate the highest levels of astaxanthin in nature; commercially more than 40g of astaxanthin can be obtained from 1kg of dry biomass. It has the advantage of the population doubling every week, which means scaling up is not an issue. However, it does require some expertise to grow the algae with a high astaxanthin content. Specifically, the microalgae is grown in two phases. First, in the green phase, the cells are given an abundance of nutrients to promote proliferation of the cells. In the subsequent red phase, the cells are deprived of nutrients and subjected to intense sunlight to induce encystment (carotogenesis), during which the cells produce high levels of astaxanthin as a protective mechanism against the environmental stress. The cells, with their high concentrations of the red pigment Astaxanthin, are then harvested.Astaxanthin can be found in plants and animals throughout the world and it is most prevelant in algae and phytoplancton which are the base of the food chain. Any sea animal that has a reddish or pinkish colour contains Astaxanthin; for example, one can find Astaxanthin in salmon, trout, lobster, shrimp and crab. As a natural source, the following can be found in nature (or a production facility) with the approximate Astaxanthin concentrations:

Source Astaxanthin concentration (ppm)
Salmonids ~ 5
Plankton ~ 60
Krill ~ 120
Arctic shrimp ~ 1,200
Phaffia yeast ~ 10,000
Haematococcus pluvialis ~ 40,000

BioAstin Natural Astaxanthin shows significantly higher free radical scavenging activity than all other antioxidants tested. Results on a pure active basis were as follows:

Natural Astaxanthin Alternate Antioxidant Multiple of Greater Free Radical Scavenging Activity
BioAstin Vitamin C; 65x stronger
BioAstin Vitamin E 14x stronger
BioAstin Beta Carotene 54x stronger
BioAstin Pycnogenol 18x stronger
BioAstin Synthetic Astaxanthin 21x stronger

Most of Natural Astaxanthin's health benefits are in some way related to its supreme antioxidant ability. Testimonials from early users along the increased scientific laboratory research led to dozens of human clinical trials demonstrating Astaxanthin's many different applications in human nutrition.
