Astaxanthin May Help Protect Diabetics
The pigment that gives salmon, lobster, and flamingoes their pink-red hue may also help protect people with diabetes against development of diabetic kidney disease and other diabetic complications. The new study, published in the Journal of Agricultural and Food Chemistry, is one of the first to report the benefits of astaxanthin for diabetics.
Astaxanthin is a potent antioxidant that has been used widely in Japan and other countries for eye fatigue, skin conditions, and muscle endurance, and it is just recently gaining a foothold in the United States. The supplement astaxanthin is primarily derived from Haematococcus pluvialis, an algae that is typically consumed by crustaceans such as shrimp, lobster, and krill. The reason flamingoes can credit astaxanthin with their pink color is that these birds eat krill and crustaceans, and the pigment is then metabolized by the body.
The new study shows that the antioxidant power of astaxanthin, which reportedly is 500 times stronger than that of vitamin E, ccan protect cells against the oxidative damage caused by high glucose (sugar) levels. High blood sugar levels and oxidative stress are associated with complications common among diabetics, including kidney disease, neuropathy (nerve damage), and diabetic retinopathy (vision problems).
