Cutting-edge micronutrition

Microvance is a range of natural high-quality food supplements with a proven effectiveness, essential for staying healthy and improving our quality of life.

Experts in Micronutrition

We have a team of researchers and doctors specialised in micronutrition. They develop our products in accordance with the latest scientific breakthroughs. We train health professionals to become experts in micronutrition at the Ysonut Academy.

Excellence in Quality

We guarantee the traceability of raw materials in the production process, from the extraction of plants or fruit extracts to the final product. Our products are free from palm oil, colouring agents, titanium dioxide, aspartame, GMOs, heavy metals, pesticides and pollutants. They are free of allergens such as gluten and lactose.

Certified products

We have more than 20 quality certificates guaranteed by independent organisations to offer you the best products.


Exclusive formulas

We develop exclusive formulas, with patented ingredients, such as plant extracts, vitamins, minerals, amino acids, etc. that act synergistically. Clinical studies are conducted on most of the ingredients used in our supplements. The bioavailability and tolerance of our products are above the market average thanks to technologies such as microencapsulation and the use of amino complexes.

Inspired by nature

Nature and sustainability at the heart of our products


We select the best of nature to guarantee maximum effectiveness. Our capsules have a vegetable or marine origin and our fish oils are eco-responsible and free of heavy metals. We prioritise sustainable cultivation and traditional hand-harvesting. Our plant extracts are carefully selected, pesticide-free and use natural solvents such as water to preserve their qualities.



This is an innovative nutritional concept created by Ysonut in 2007 based on nutritional chronobiology. It consists of adapting products to the body's biological rhythms to ensure greater effectiveness and tolerance.
