We are often told that we have to choose.

Be a successful entrepreneur OR a present parent.

Be a dedicated athlete OR have a vibrant social life.

At Onday, we believe life is richer when it’s multifaceted.

But we also know what that entails: intense days and a body pushed to its limits.

You don't want to compare 15 supplements, check every dosage, or doubt the quality of what you put in your body.

Neither do we.

That is why we spent months crafting the perfect formula for you.

A single, comprehensive foundation of absolute excellence.

Simple, reliable, made in France.

We took the time to do everything right, so you don't have to waste yours searching.

Ultimately, Onday is the supplement that keeps up with your pace.

For those who live multiple lives in one.

For you.

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

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!
