Mechanism of action

1

Mogroside Sweetness

Mogrosides are triterpene glycosides; mogroside-V is most abundant and sweetest; 250× sucrose sweetness; not metabolized for energy.

2

Antioxidant Activity

Mogrosides have additional antioxidant activity beyond sweetening function.

3

No Insulin Response

Does not stimulate insulin release; appropriate for diabetes management.

4

Heat Stable

Stable in cooking and beverage applications; versatile formulation.

Clinical trials
