OTPP in oolong tea helps to reduce fat absorption and increase fat elimination

Oolong tea and OTPP Key benefits

Visceral fat area -11.32cm2 (*3)

Consumed two bottles of oolong tea containing OTPP per day (16 weeks) *3 Adapted from 薬理と治療 (Pharmacology & Therapeutics), 39(10), 889-900 (2011)

Fats in food are absorbed by the small intestine. Here, the fats are broken down for absorption in the body by an enzyme called lipase. OTPP interferes with the activity of lipase, inhibiting fat absorption and resulting in unabsorbed fat being excreted in the stool.

Participants: 281 moderately overweight adult men and women with a BMI of 25 to 30 kg/m2
Data represents averages, measured with abdominal CT scans before and after participants consumed one bottle (350 mL) of either Kuro-Oolong Tea OTPP or a control beverage which did not contain OTPP with meals twice a day for 16 weeks.

After eating a high-lipid diet, consumption of oolong tea with OTPP significantly increased lipid excretion in feces compared with the control beverage.
Participants: 12 healthy adult men and women
Data represents averages. Lipid excretion in feces was measured over three days of a 10-day treatment period during which participants consumed three bottles daily of either OTPP-enriched oolong tea (containing 68 mg of oolong-tea polymerized polyphenols per bottle) or a control beverage (prepared with tea flavor and caramel coloring) with high-lipid meals. *4 Graph based on European Journal of Clinical Nutrition, 60(11), 1330-1336 (2006)
