Take care of yourself to live better

Improve your well-being with a simple and effective micronutrition routine

Because providing the body with its essential nutrients should not be so complicated, we believe in the power of simple daily micronutrition. What drives us is to give you back the keys to a healthy, complete and innovative nutritional base: a feel-good routine, a gesture that changes everything.

The first step to living better is to take care of yourself. A few moments in the morning, a break just for you to boost your health: you are in shape, ready to face your daily challenges. You finally enjoy your days as you deserve, because life is much more pleasant when you feel fully ready physically and mentally.

No superlatives, just your favourite version of yourself. The one that is rested, responsive, energetic ; the one that feels good and can live fully.

Every day becomes an “on” day.

Our story

Aware of the nutritional deficiencies of our Western diets, tired of the medicinal aspect of food supplements, their daily accumulation in our kitchens, and above all their lack of effectiveness, we have developed the first all-in-one food supplement routine, simple and pleasant, which provides high quality essential nutrients to your body!

Our ingredients

Each ingredient in onday has been meticulously selected by a team of experts in our HACPP-certified French laboratory. Uncompromising on quality, we chose the most bioavailable forms (i.e. the most absorbed and used by the body) for optimal effectiveness, as well as the most qualitative and environmentally friendly. For example, we have refused to use plants that are endangered or whose carbon footprint is unreasonable.

Our commitments

Designed and produced in France

onday is made in France, in Saumur (Maine-et-Loire), where we continuously test and monitor all our ingredients for optimum effectiveness and quality.

HACCP approved production site

Thanks to its HACPP certification, our laboratory meets our requirements for quality, rigor and intransigence regarding safety standards and ingredient management.

Uncompromising quality

Each ingredient in our formula comes from a rigorous selection and has been chosen for its quality, its benefits and its synergies with other ingredients.

Vegan & gluten-free

onday contains no preservatives, added sugar, or gluten ; and is also suitable for vegans, and therefore also for vegetarians!

Improved well-being

By providing you with vitamins, minerals, plants, probiotics, antioxidants and amino acids, our complete formula with multiple benefits contributes to your daily well-being: and that is our greatest source of joy!

Respect for the environment

Each of our choices is motivated by a responsible approach: we ensure that we opt for the most environmentally friendly solution for each stage of our value chain.

Who are we ?

We met in 2014 in college. After 10 years of friendship and very complementary paths, it was in 2024 that we decided to put one of our passions together: nutrition!

After several years of high-level sport and recurring injuries, we became interested in different ways to optimise our physical and mental capacities, for better health on a daily basis and in the long term.

Nutrition quickly emerged as a key factor. But building an effective wellness routine is not so simple: accumulation of different food supplements, multitude of ranges and offers, lack of visibility on the origin and quality of ingredients, medicinal and restrictive aspect of capsules and tablets.

So it was natural that we needed a new kind of food supplement: all-in-one, simple and effective, for a positive routine without the hassle. onday was born!
