Look beyond one number
Blood sugar regulation involves more than what you eat
Food matters, but it is not the only part of the picture. Digestion, the liver, and how cells respond to insulin all influence glucose regulation. That is the idea behind the Three-Door Glucose System.
Door 1
Digestion
Carbohydrates are broken down during digestion before glucose enters the bloodstream.
Door 2
The liver
The liver stores and releases glucose as part of the body's normal energy regulation.
Door 3
The cells
Insulin helps cells take in glucose so it can be used for energy.

Study context: The study recruited 38 healthy adults and analyzed 36. It tested 250 mg of Reducose mixed directly into a 75 g sucrose drink, not Glucose Manager or a swallowed Glucose Manager capsule. The reported 42% difference was the 120-minute incremental area under the glucose curve (iAUC), an acute response measure, and does not establish that Glucose Manager will produce the same effect. The study was funded by Phynova Group Ltd., the developer of Reducose; one author was a Phynova employee.
