According to Natural Factors Nutritional Products handout this is how PGX works.
The dietary fibre in PGX improves insulin sensitivity and reduces the health risks associated with insulin resistance.
When taken shortly before a meal, PGX absorbs water and expands, substantially increasing the viscosity (thickness) of food in the digestive tract. This slows the absorption of carbohydrates, effectively lowering the glycemic index of the food. By slowing the release of glucose into the bloodstrem, PGX smoothes out the peaks and crashes of the unhealthy blood sugar roller coaster. This helps you feel full longer and reduces food cravings, between meal snacking and weight gain.
PGX also increases the volume of your meal without significantly increasing the calories. By increasing the volume of food in your stomach, PGX makes you feel fuller, which makes it easier to eat less and lose weight.
The beneficial effects of soluble dietary fibre are directly proportional to the amount of water the fibre can absorb. The unique combination of fibres in PGX can bind several hundred times its weight in water and stomach fluids, far more than other soluble fibres like psyllium or oat beta-glucan. PGX Daily Ultra Matrix Softgels represent a new frontier for helping you achieve and maintain metabolic health.
For best results take PGX daily 15-20 minutes before meals with 375 ml of water.
Week 1: 1-2 softgels 3 times per day
Week 2: 2-4 softgels 3 times per day
Week 3 +: 3-6 softgels 3 times per day
Seems to me the dosage recommendations keep changing?!?
