Your body is desperately lacking support
Pollution, depleted soils & an intense pace. Your supplements can't keep up.
Needless stacking
Pills piled up every morning, with no synergy between them.
Results that fade
One-off, overdosed cures whose benefits vanish the moment you stop.
Total opacity
Low-grade ingredients, poorly absorbed forms, and unclear origins.
You need precision nutrition
We've brought together 44 ultra-absorbable active ingredients in a single formula to drink every morning.
Everyday simplicity
One complete formula to drink, replacing 16 separate supplements.
Effectiveness you can measure
Optimized physiological dosages for deep, lasting results.
Rigorous traceability
Highly absorbable pure forms, made in France in a certified lab.
44 exceptional active ingredients in a single formula
Pure forms and maximum synergy: a formula designed for real results.
11 essential vitamins
Vitamins B1, B2, B3, B5, B6, B8, B9, B12, C, D3, K2
A complete complex of essential vitamins in their most absorbable forms. It acts directly at the heart of your cells to turn what you eat into usable energy, boost your vitality throughout the day, and keep your immune shield at its peak.
5 minerals & electrolytes
Magnesium, Zinc, Potassium, Chromium, Selenium
The key minerals your body needs to stay on top of its game without burning out. This synergy helps your nervous system better handle daily pressure, prevents energy crashes, and keeps your energy level stable and smooth, without causing jitteriness.
10 fibers & probiotics
A blend of probiotics, prebiotic fibers, and targeted plant extracts. It nourishes your microbiome, eases bloating, and resets your digestive system so you get a lighter belly and maximum absorption of all your nutrients.
13 superfoods
Spirulina, Moringa, Ashwagandha, Ginseng, Beetroot, Nettle, Acerola, Broccoli, Carrot, Spinach, Barley, Ginger, Milk Thistle
A concentrate of plants and so-called “adaptogenic” superfoods. They help your body adapt to periods of fatigue or intense stress, regulating your energy levels to spare you the emotional and physical rollercoaster.
3 amino acids
Glycine, L-Glutamine, Taurine
Three essential amino acids that help your body repair itself from within. They support tissue regeneration, protect your gut lining, and speed up physical recovery after an intense effort or a particularly demanding day.
4 antioxidants
Coenzyme Q10, Hyaluronic acid, Lutein, Quercetin
A powerful antioxidant cocktail designed to protect your cells against everyday aggressors (pollution, stress, an intense pace). It slows premature aging of the body, preserves your long-term health capital, and supports the hydration of skin and tissue.
Physiological dosages, not overdoses
Your body isn't built to absorb massive spikes of nutrients.
Onday gives you every day exactly what it can absorb.
Your nutrient level with a classic 3-month cure
High doses, one-off use. The body can't store it all, so the deficit returns as soon as you stop.
The onday routine, every day
Physiological dosages, continuous use. The body stays in its actual need zone, with no spikes or setbacks.
Your body, strengthened,
a little more every day
Metabolism wakes up
That feeling of a lighter, more energetic body
Energy
A lighter wake-up and steady vitality, without the energy crashes.
Digestion
A rebalanced microbiome and a lighter belly after meals.
Vitality returns
Easier to get out of bed, a clearer mind
Sleep
Falling asleep faster and restorative nights to recharge your batteries.
Mental clarity
Energy from the moment you wake up, sharper focus, and a clearer mind.
Deep reinforcement
Fewer slumps, more resilience
Immunity
A stronger natural shield to better withstand outside aggressors.
Recovery
A body that bounces back faster after exercise, with less physical fatigue.
Lasting balance
Cellular protection, an overall glow

A mood that finally feels stable, with cells protected over the long term.

Deeply hydrated skin, and stronger hair and nails.
