Fucoxanthin Promotes Blood Sugar Regulation and Fights Obesity

Posted on November 25 2016

Fucoxanthin is a chemical found in brown algae that has become a popular supplement.  Some of its purported benefits include increased fat release and metabolism, increased thermogenesis, weight loss, antioxidant activity and cancer cell suppression. A literature review on the metabolic effects of fucoxanthin by Hayato Maeda from Hirosaki University in Japan concluded that it improves blood sugar control by reducing insulin resistance. It does this by suppressing adipocytokines in fat cells and activating GLUT4, which is a sugar transporter in cells. He concluded that fucoxanthin promotes metabolic health. We need well-controlled, large-scale studies before we can recommend this supplement for weight loss and blood sugar control.
