About

Investigators research team conducted a previous human clinical trial of brown algae and conducted liver and metabolic indicators of brown algae to improve nonalcoholic fatty liver disease, and found brown algae extract (LMF-HSFx, commodity In addition to reducing the liver function index, HbA1c in some patients with early stage diabetes or type 2 diabetes has an improved effect. In the mouse model of type 2 diabetes, comprehensive anti-hyperglycemia, anti-hyperlipidemia and hepatoprotective activity were studied using LMF-HSFx. Intake of LMF-HSFx reduced fasting blood glucose, increased adiponectin levels, reduced urine glucose, and improved hepatic glucose metabolism. LMF-HSFx can improve glucose and lipid metabolism in adipose tissue of diabetic mice, and inflammatory factors such as TNF-α and IL-6 can also be reduced.

In this study,participants will be given Fuco-HiQ, and their effects on blood glucose and various metabolic indicators will be evaluated.

Full description

Brown seaweeds rich in flavonoids and bioactive polysaccharides have been shown the potential effects on suppressing fat accumulation, oxidative stress and inflammation in liver. The refined seaweed compounds such as low-molecular-weight-fucoidan (LMF) and high stability fucoxanthin (HSFx), have not been well studied for its biological function.

The high stability fucoxanthin (HSFx) and the low-molecular-weight fucoidan (LMF) were produced by HiQ Marine Biotech Company in Taiwan. Study use fucoidan-fucoxanthin mixture (abbreviated as LMF-HSFx, each capsule contains 275 mg LMF and 275 mg HSFx).

Insulin resistance has a high correlation with fatty liver. Our research team conducted a previous human clinical trial of brown algae and conducted liver and metabolic indicators of brown algae to improve nonalcoholic fatty liver disease, and found brown algae extract (LMF-HSFx, commodity In addition to reducing the liver function index, HbA1c in some patients with early stage diabetes or type 2 diabetes has an improved effect. In the mouse model of type 2 diabetes, comprehensive anti-hyperglycemia, anti-hyperlipidemia and hepatoprotective activity were studied using LMF-HSFx. Intake of LMF-HSFx reduced fasting blood glucose, increased adiponectin levels, reduced urine glucose, and improved hepatic glucose metabolism. LMF-HSFx can improve glucose and lipid metabolism in adipose tissue of diabetic mice, and inflammatory factors such as TNF-α and IL-6 can also be reduced.

Based on these studies, we hope to further explore whether LMF-HSFx can improve insulin resistance and thus assist blood glucose control.In this study,subjects will be given Fuco-HiQ, and their effects on blood glucose and various metabolic indicators will be evaluated.
