Red Algae Extract (Astaxanthin)
Astaxanthin is a type of carotenoid. In recent years, it has been discovered that astaxanthin can effectively reduce the production of free radicals and possesses strong antioxidant properties. Products derived from or containing astaxanthin have been shown to have beneficial health effects on vision, circulation, and skin beauty, and are therefore widely used in health supplements and skincare products.
Astaxanthin is found in algae and marine organisms, with the primary source for extraction being Haematococcus pluvialis. Haematococcus pluvialis is a single-celled green alga that lives in freshwater and has high nutritional value. When faced with extreme environmental conditions, its cells can rapidly accumulate large amounts of astaxanthin, forming a self-protective mechanism that demonstrates its strong vitality.
The structure of astaxanthin is similar to that of -carotene and lutein, but it possesses additional hydroxyl () and carbonyl () groups. This effectively increases the molecule’s overall hydrophilicity. As astaxanthin is both lipophilic (fat-soluble) and hydrophilic (water-soluble), it can span the entire phospholipid bilayer of the cell membrane, exerting antioxidant effects both inside and outside the cell. According to research, astaxanthin can cross the Blood-Brain Barrier (BBB), supporting central health.
It is recommended to take astaxanthin after or with a meal, particularly with foods containing fats, to enhance its absorption rate. With its strong antioxidant capacity, astaxanthin provides excellent protective effects, making it suitable for the health maintenance of frequent cellphone users, individuals who read for extended periods, office workers who use computers regularly, and elderly people.
Utilizing the stable sunlight in Israel provides an ideal environment for the red algae raw material. Through a patented technology, the microalgae are cultivated in a closed-system photobioreactor. This facility eliminates any potential chemical, physical, or microbial contamination, thereby enabling the extraction of astaxanthin with high activity and purity.
