简要总结
It is well known that Chitosan oligosaccharide is low molecular weight and water soluble and chitosan oligosaccharide has been shown to reduce blood cholesterol and blood pressure, increase immunity, and enhance antitumor properties. the effect of chitosan oligosaccharide (GO2KA1) supplementation on glucose control in subjects with normal blood glucose, impaired fasting glucose and impaired glucose tolerance.
详细描述
A randomized, double-blinded, controlled, cross-over trial was conducted to verify the effects of chitosan oligosaccharide (GO2KA1). forty healthy male and female subjects aged 20-75 years with normal blood glucose, impaired fasting glucose and impaired glucose tolerance were recruited. The subjects visited the research site twice over with a seven-day interval after an overnight fast at least 12 hr. On the screening visit, the participants were the 2-hr oral glucose tolerance test (OGTT) was conducted. And they were separated normal blood glucose, impaired fasting glucose and impaired glucose tolerance. On the first visit, the participants were randomly assigned to consume a test or placebo product [test product: chitosan oligosaccharide powder 500mg (GO2KA1); placebo product: white egg powder 500mg] and ingested the assigned product. On the second visit, the participants consumed the other product that they did not eat on the first visit. On both visit day, the 2-hr oral sucrose tolerance test (OSTT) was conducted and started at 8:00 in the morning; venous blood samples were collected before (0 hr) and after ingestion (0.5, 1 and 2 hr) of the products.

研究组 & 干预措施
Chitosan Oligosaccharide (GO2KA1)
Chitosan Oligosaccharide (GO2KA1) capsule was provided to the study participants. The Chitosan Oligosaccharide (GO2KA1) capsule was consumed within 15 min, and then 2-h oral sucrose tolerance test was conducted. The Chitosan Oligosaccharide (GO2KA1) one capsule had Chitosan Oligosaccharide 250mg.
干预措施: Chitosan Oligosaccharide (GO2KA1) (Dietary Supplement)
White egg
White egg capsule was provided to the study participants. The White egg capsule was consumed within 15 min, and then 2-h oral sucrose tolerance test was conducted. The Chitosan Oligosaccharide (GO2KA1) one capsule had White egg 250mg.
干预措施: White egg (Dietary Supplement)
