Astaxanthin is a natural antioxidant found in abundance in Arctic Ocean Krill Oil from Natural Biology. The biggest benefit is immune system support and now we are discovering even more benefits thereof.
If your health professional says you have hyperlipidemia, this simply means the amount of fat in your blood is higher than it should be. ("Hyper" means high; "lipid" is another word for fat or fat-like substance; "emia" refers to the blood.) Although high cholesterol is the most famous form of hyperlipidemia, blood fats include more than just cholesterol. Triglycerides, phospholipids, and other fatty substances circulate continuously through the bloodstream on their way to and from organs and tissues.
Astaxanthin belongs to a group of compounds called carotenoids. While b-carotene is a vitamin A precursor, astaxanthin cannot be converted to vitamin A. In laboratory studies, astaxanthin has been reported to be typically at least 10 times more potent as an antioxidant than the other standard carotenoids such as canthaxanthin, b-carotene, lutein, lycopene, tunaxanthin and zeaxanthin. Astaxanthin provides the rich pink color observed in various aquatic species including salmon, crabs, lobster, shrimp and even some nonaquatic species such as the flamingo (whose diet includes some astaxanthin-producing organisms).
A recent study has found that supplementation with natural astaxanthin increases HDL and decreases triglycerides in patients with mildly high cholesterol. The study included 61 non-obese adults between the ages of 25 and 60 years with fasting serum triglycerides levels between 120 and 200 mg/dl and who did not have hypertension or diabetes. The patients were randomly assigned to receive either astaxanthin or placebo at doses of 0, 6, 12 or 18 mg per day for 12 weeks. The results of the trial revealed that at doses of 12 and 18 mg per day astaxanthin significantly reduced levels of triglycerides in the study participants. It was also discovered that 6 and 12 mg per day doses increased serum HDL cholesterol in the subjects. There was no change in LDL cholesterol or BMI at any dosage amount. These results suggest that astaxanthin may be a useful supplement for people with mildly elevated triglycerides or for people who need to increase their serum HDL levels.1
