With safety first in mind, each ingredient must also pass the rigorous standards of GRAS (Generally Recognized As Safe) by the US FDA. Strict quality control over the entire production and distribution process, as well as the most advanced technologies to guarantee the quality and safety of the final product, is similar to those used by ethical pharmaceuticals.
  • Italian Ayurveda

    Our European heritage is at the base of a philosophy inspired by the principles of Ayurveda, a system of medicine practiced in India for thousands of years. Ancient science made modern; or as President Truman is quoted as saying: "the only thing new is the history you never learned"; which is why Sensoril® (commonly known as Ashwagandha) plays such an important role in our Dormiva® and Relaxiva® formulations. Sensoril® is a highly purified extract of the Withania somnifera plant, using the roots and leaves in a patented water extraction process.

    One of the most powerful herbs in Ayurvedic healing, Ashwagandha has been used since ancient times for a wide variety of conditions, and is most well-known as an adaptogen (natural substances that help the body to adapt to stress and exert a normalizing effect upon bodily processes) with restorative properties. The use of Ashwagandha may help alleviate stress, fatigue, lack of energy, insomnia, and impaired concentration.
