Astaxanthin lowers cholesterol and CVD risk in people with prediabetes and dyslipidemia
USA: A recent study published in Diabetes, Obesity and Metabolism has shown that astaxanthin, a natural antioxidant is a safe over-the-counter (OTC) supplement that improves markers of CVD (cardiovascular disease) risk and lipid profiles in people with prediabetes and dyslipidemia.
"The authors wrote, "although the primary endpoint did not meet the prespecified significance level."
Astaxanthin is a natural carotenoid having anti-inflammatory and antioxidant effects. It can resist diseases caused by oxidative stress, such as neurodegenerative diseases, metabolic syndromes, inflammatory diseases, cardiovascular diseases, and age-related diseases. Cardiovascular disease is the leading cause of death in the world. There has been a rise in research showing that astaxanthin affects cardiovascular disease. However, there are some controversies about the conclusions.
Against the above background, Theodore P. Ciaraldi from the University of California in San Diego, La Jolla, CA, and colleagues conducted a double-blind, placebo-controlled, randomized trial to determine the effects of treatment with astaxanthin on glucose tolerance, CVD markers, lipids, inflammation, and insulin action in people with dyslipidemia and prediabetes.
The study included 34 adult participants with dyslipidemia and prediabetes who underwent an oral glucose tolerance test (OGTT), blood draw, and a one-step hyperinsulinemic-euglycemic clamp. Twenty-two were randomized to the treated group (astaxanthin 12 mg daily) and 12 to the placebo for 14 weeks. Following 12 and 24 weeks of therapy, baseline studies were repeated.
