What is Astaxanthin Powder?
Astaxanthin is a naturally occurring carotenoid with a deep red color and free radical scavenging ability. It is widely used in dietary supplements, functional foods and cosmetics. Haematococcus pluvialis accumulates astaxanthin as a protective mechanism against environmental stress. Through advanced cultivation and extraction techniques, we ensure a stable, high-purity natural astaxanthin that retains the full spectrum of bioactive compounds.
Undersun sources natural Haematococcus pluvialis algae cultivated under controlled, pollution-free conditions. We extract astaxanthin using supercritical CO₂ extraction to ensure purity, safety, and environmental sustainability. Every step of production utilizes full traceability and stringent quality control. Our astaxanthin is available in a variety of specifications to meet the needs of manufacturers of supplements, food, and cosmetics.
Best astaxanthin is perhaps the very best nutrient for anyone over the age of 40 to take on a daily basis. The clinically validated benefits of Natural Astaxanthin in areas that most concern people as they age are quite comprehensive; practically every concern for people approaching middle age and beyond is at least to some extent addressed by this single supplement: Cardiovascular health, eye & brain health, skin health & UV protection, immunity, energy & strength levels, aches & pains, cellular health-research indicates that Natural Astaxanthin addresses all of these and more.
It is our opinion that every consumer over the age of 40 should be supplementing with at least 4mg of Natural Astaxanthin every day. And even people under the age of 40 should consider Astaxanthin as a great preventive supplement.

astaxanthin Benefits
In a recent study, mice inoculated with human prostate cancer cells were given two different doses of astaxanthin - 25 mg/kg or 100 mg/kg (about 11 mg/lb. or about 45.5 mg/lb.) - or a placebo. In roughly one month's time, tumor volume (the percentage of the prostate taken up by the tumor) was 40% smaller, and tumor weight was reduced by nearly that same amount in the group that received the higher astaxanthin dose. An increase in the expression (communication of protection) of tumor suppressor gene - a gene that protects a cell from taking another step on the path to cancer - was also noted.
