The beginning was the tea…

Dear Customers,

As the team behind N.U.S. AG, we are pleased to share with you the guiding principles that define the Uwemba-Pastilles® brand. In a time when health products are often launched with exaggerated claims and confusing promises, we focus on clarity, natural integrity and trusted quality.

Our formulations combine a diversity of plant-based ingredients with scientifically recognised micronutrients – developed to support the body in everyday life and to contribute to a more mindful and balanced lifestyle.

The story of Uwemba-Pastilles® began in south-western Tanzania, where the Benedictine mission in Uwemba conducted its first work with traditional plant-based formulations. Over the years, this idea evolved into a solid concept that unites botanical heritage with modern quality standards.

Today, all production takes place in Switzerland, under GMP-compliant conditions and with the utmost care in selecting and processing raw materials. The original idea remains, but has been continuously refined to meet today’s expectations for purity, safety and consistency.

Many of our customers – including experienced health practitioners – value the high quality, the rich variety of natural ingredients, and our ongoing commitment to transparency, sustainability and responsibility.

Thank you for your trust.
Your N.U.S. AG Team
