How to use

(01)

Stir one sachet in a glass of water

Use cold water (200-250 ml, depending on your preference). You can also mix it with juice or yogurt.

(02)

Mix thoroughly

Small lumps may appear — this is normal, as we do not use anti-caking agents. For a smoother texture, use a shaker or a handheld frother.

(03)

Drink daily

Ideally in the morning, on an empty stomach or after a light meal with little fat, to support optimal nutrient absorption.

FAQ

Only One is designed for active adults navigating demanding daily lives, who want to support their energy, focus and overall balance while taking a preventive approach to healthy ageing — without the need for multiple supplements.

Only One is an all-in-one supplement designed to help address common nutritional deficiencies and support core physiological functions.

Its formula primarily targets energy metabolism, immunity, stress resilience, cognitive function and cellular protection mechanisms.

The full list of benefits is available here.

Only One is built on a no-compromise approach to simplification. While most routines rely on multiple products, it concentrates what truly matters into a single daily intake.

Its formulation combines high-quality ingredients (highly bioavailable forms, standardised extracts, certified organic botanicals), with careful attention to nutrient synergy and complementarity. Each ingredient is precisely dosed to deliver benefits without excess or imbalance.

Developed and manufactured in France in an ISO 22000 and GMP-certified facility, Only One undergoes systematic quality, purity and safety testing on every batch by an independent laboratory.

Dosages are defined for continuous daily use, based on:

— Official nutritional references (ANSES / EFSA)
— Available clinical data for each ingredient
— Nutrient interactions, including both synergies and competitions

The formula does not aim to maximize dosages, but to reach levels that are effective and physiologically relevant. Some actives are included at targeted doses, while others work in synergy. This approach is designed to optimise how nutrients are utilised by the body, rather than relying on high quantities that may be poorly absorbed.

We prioritise balance: providing what is needed, without unnecessary excess, to support the body’s function over time.

The taste is intentionally light, with a subtle green apple note.

The formula contains no added sugar. We use a natural sweetener (stevia), along with a natural flavour developed by a French laboratory.

The powder format allows for rapid dissolution, with no coating to digest, and promotes good digestive tolerance.

The powder format allows for rapid dissolution, without the need for a coating to digest, supporting digestive tolerance.

It brings together all actives in a single intake, without the need for multiple capsules, and integrates into a combined approach to hydration and micronutrition.

Some individuals may experience improvements in energy or mental clarity within a few days to a few weeks, particularly when initial intake is suboptimal. Other benefits develop progressively over time, as the body restores its balance.

Ideally taken in the morning, on an empty stomach or after a light meal containing some fat to support the absorption of fat-soluble nutrients.

This timing allows for an easy integration into a daily routine and supports energy metabolism from the start of the day.

Only One covers a broad spectrum of needs and can replace multiple supplements commonly taken separately (multivitamins, magnesium, vitamin C, vitamin D + K, zinc, spirulina, adaptogens, antioxidants, coenzyme Q10).

Before introducing additional products, it is recommended to assess total intake to avoid unnecessary overlap. If in doubt, consult a healthcare professional.

Yes. A balanced diet does not always ensure optimal micronutrient intake, which may vary depending on individual needs and lifestyle.

Only One is designed to complement these intakes and support key physiological functions, without substituting a healthy diet.

Iron is a specific nutrient, and supplementation should be individualised. Excess intake may contribute to pro-oxidant processes, and requirements vary widely depending on individual profiles.

For this reason, Only One does not include added iron. The formula does, however, contain spirulina, a natural source of it.

Some ingredients — particularly botanicals and plant extracts such as spirulina, ashwagandha, reishi, pomegranate extract and acacia fibre — are sourced from certified organic farming.

Other actives do not fall within organic classifications due to their cultivation or extraction processes (e.g. hyaluronic acid, coenzyme Q10, minerals).

As a result, the formula as a whole cannot be certified organic.

Only One is manufactured in France in an ISO 22000 and GMP-certified facility, ensuring high standards of quality, safety and traceability.

Each batch undergoes additional testing by an independent laboratory, including testing for heavy metals and other contaminants.

The subscription allows you to receive your product automatically each month at a preferred rate, with a complimentary bottle included in the first order.
