Tenaci | Food Supplements
TENACI creates powdered food supplements formulated with selected vitamins, minerals, and natural extracts. Each blend is designed to dissolve easily in water but can also be enjoyed in yogurt or used to prepare smoothies rich in taste and wellness.

A ritual that evokes your strength
For TENACI, each supplement is more than just a product: it's a daily ritual. Every ritual evokes an inner strength, represented by a symbolic animal that embodies energy, balance, resilience, and determination. It's a way to transform a daily gesture into a moment dedicated to one's well-being.
Swiss certified quality
All TENACI supplements are developed and produced in Switzerland by Swissmedic certified companies, in compliance with GMP standards and ISO 22000.
Every stage of production is controlled to ensure quality, safety, traceability, and reliability, according to high Swiss standards.
Original formulas
TENACI formulas are created by Valentina Barri, the brand's founder, and are born from the synergy of scientific research, formulation expertise, and careful selection of raw materials.
Each product is the result of careful study aimed at creating innovative, balanced, and highly bioavailable formulations, so that nutrients can be used by the body in the most effective way.
The TENACI Technology
Bioavailability is one of the most important aspects in formulating a supplement: it's not enough to take a nutrient, it's essential that the body can recognize and utilize it.
For this reason, TENACI has developed a formulation approach that combines selected ingredients and production technologies designed to promote nutrient availability and support their physiological absorption.
The result is formulations designed to work in harmony with the body, enhancing the properties of the ingredients and offering concrete support for daily well-being.
"An organ is healthy when everything around it is in balance and harmony."
