Thylakoids are plant membranes that have the unique ability to decrease appetite and increase satiety.* Appethyl® is a patented, all-natural extract of spinach, which is particularly high in thylakoids.
To date, six human clinical studies have been conducted on Appethyl®, finding that this unique ingredient:,,,,,
Reduces feelings of hunger*
Promotes weight loss, in one trial by 82 percent more than control (6.8 lbs vs 3.7 lbs)*
Reduces waist circumference, in one study by 180 percent more than control (3.81 cm vs. 1.36 cm)*
Helps maintain blood sugar and cholesterol already within normal limits*
No wonder Appelthyl® won the NutrAward for Best New Ingredient in 2013! Four more human clinical trials are underway.
Thylakoids support a healthy weight in several ways. Primarily, they reduce the absorption of fat by temporarily inhibiting the fat-digesting enzyme lipase.* They also promote satiety by increasing satiety hormones, such as PPY, enterostatin, and leptin. In addition, they suppress appetite, by decreasing hunger hormones such as ghrelin.* And finally, they help regulate insulin, which controls fat storage.*
The thylakoids in Appethyl® come from spinach leaves, which have been safely consumed by humans for over 1,300 years. Additionally, Appethyl® has been tested in humans and animals without serious adverse events.
