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!
Take care of yourself to live better
