The roots of E.longifolia have been traditionally used as an anti-aging remedy and also as a male aphrodisiac. Modern scientific research attributes those beliefs to the proven evidence that E.longifolia has anti-oxidant effects, as well as a regulatory action on testosterone & cortisol.

Our research discovered that E.longifolia also reduces core body temperature. A robust diurnal rhythm of the core body temperature can be controlled, and in turn help to improve sleep, through sleep initiation and promoting deep sleep.

The cooling effect of Nineteen°’s innovative formula shortens the time taken to fall asleep and improves the quality of deep sleep. Additionally, E.longifolia regulates the hypothalamic-pituitary-adrenal (HPA) axis and key mediators of stress response to bring your body back to a steady energy balance when you wake.

This dual function of deep sleep promotion and subsequent energy activation is what sets NINETEEN° apart.
