natural astaxanthin

Biological source of natural astaxanthin generally have three kinds: aquatic products processing industry waste, Phaffia yeast (Phaffia rhodozyma) and microalgae (Haematococcus algae). Among them, the waste astaxanthin content is low, and the high cost of extraction is not suitable for mass production. Natural yeast Phaffia astaxanthin average content of 0.40%. In contrast, the rain pluvialis astaxanthin content was as high as 1.5% to 3.0%, so it is seen as a natural astaxanthin "concentrates."
