Haematococcus pluvialis is a freshwater single-celled green alga, belonging to Chlorophyta, Volvox, Haematococceae, and Haematococcus. The algae can accumulate a large amount of astaxanthin and due to its red appearance, its name is Haematococcus, also known as Haematococcus pluvialis.
It is the organism with the most abundant astaxanthin content in nature, and its astaxanthin content can reach 3.0% of the dry weight, or even higher. It is known as the "concentrated product" of natural astaxanthin and is considered to be the The best biological sources.
There are two states during the growth of Haematococcus pluvialis:
One is the state when the environment is suitable for growth. At this time, Haematococcus pluvialis will continue to reproduce, and the number will increase rapidly. At this stage, they are all green.
The other is the state when the environment is harsh, such as the pH and temperature become particularly unsuitable for their growth. They will stop reproducing, and the body will start to produce a large amount of astaxanthin to get through this difficult stage. At this time, the cells become red.
In 1996, the Nutrition Research Center of the United States Department of Agriculture revealed an amazing and miraculous mystery. Salmon and fish in the ocean contain a substance called astaxanthin, which is the antioxidant with the strongest ability to inhibit the absorption of free radicals found in nature so far.
Astaxanthin is an oxygenated carotenoid derivative, one of more than 600 carotenoids. Studies have shown that astaxanthin has a strong ability to scavenge oxygen free radicals, and its antioxidant activity is 10 times that of carotenoids and 550 times that of vitamin E. It is known as a "super oxidant".
Astaxanthin improves the human immunity, inhibits tumor occurrence, delays aging, and maintains various physiological functions of eyes, liver and central nervous system.
