Our story

Friends since 2014, it all began back in our school days.

  • Coline Helmreich
    Coline HelmreichCo-founder
  • Arthur Legrand

We quickly realized we shared the same pace of life: lots of sport, a busy social life, an intense family life... and a refusal to make any compromises!

Back then, we each took several capsules every morning. It was neither pleasant nor reassuring: reading the labels, we often found vague origins or pointless overdosing.

We felt we were missing a real nutritional foundation, able to give our bodies everything they need in one simple, effective routine. We wanted a solution with no compromise on quality, and 100% French.

So we spent months developing the optimal formula. For us, for you, because we all deserve to feel good every day. Onday was born!
