Natural food supplements in liquid form,
to help us feel well and happy.
We created the food supplements we had always wanted for our family, our friends and ourselves. Natural liquid formulas, developed and made in France, to explore according to your interests and needs.
We seek the truth, knowing we will never have the final word. A discovery, an encounter, an unexpected question: there is always something to inspire wonder — and sometimes to make us rethink our answers.

Six bottles, focused formulas.
Vitality, emotional balance, joint comfort: discover the ingredients that fascinate us and the formulas we have developed around them.
Phycocyanin ω X35
Spirulina’s blue pigment, concentrated in a liquid formula. Phycocyanin is studied for its antioxidant properties and its interactions with inflammatory mechanisms. X35 offers a way to explore this ingredient at a higher concentration than X12.
Phycocyanin ω X12
Phycocyanin in the X12 format. The same blue pigment from spirulina, at a different concentration: an introduction to our liquid range, with quantities and directions detailed on its product page.
Saffron ω
Saffron and lemon balm brought together around emotional balance and relaxation. Saffron may contribute to a positive mood; lemon balm is studied in relation to relaxation and sleep. Ingredient references: saffron ID 2038; lemon balm IDs 2300–2302.
Curcumin ω
Curcumin is studied for its antioxidant properties and its potential role in joint comfort. Our liquid formula comes in several formats, to compare by concentration and quantity per serving. Turmeric references: IDs 2598 and 3748.
Spirulina ω
Spirulina may support vitality and the body’s natural defences. Our liquid preparation invites you to rediscover this ingredient: its composition, the amount per serving and its place in your daily routine. Spirulina references: IDs 2737 and 2583.
Collagen HA Omega
Hydrolysed marine collagen peptides, hyaluronic acid, curcumin, vitamins and minerals: a liquid formula developed around skin and connective tissues. Vitamin C contributes to normal collagen formation for the normal function of skin and cartilage.
The reference IDs refer to health claim applications concerning the ingredients. They are neither authorisations nor evidence of the formulas’ effectiveness. Each product page provides the context, studies and composition.
Formulas we want to share
Some ingredients make you want to find out more. How can spirulina hold such a vivid blue? What does a saffron stigma contain? That curiosity lives in our formulas and in the pages we enjoy sharing with you.
Inspired by ingredients
A plant, an extract, a preparation: the story of a formula begins long before its name. On each product page, we invite you to get to know the ingredients brought together in the bottle.
A bottle in your daily life
You also discover a formula by using it. How much should you measure? How should you take it? How long will the bottle last? These practical questions deserve answers as thoughtful as the choice of ingredients.
For curious minds
Laboratory analyses tell us about an ingredient; studies explore its properties. Our pages let you look at both, including their methods and what they help us understand.
Have a question? Let’s talk.

Debunk is us when a discovery excites us and we want to see how far its findings hold. Who took part in the study? Which preparation was used? What was actually measured? Through En clair, we follow what sparks our curiosity, test our convictions against the results and share the pleasure of understanding.
Why “Omega”
The ω symbol accompanies our formulas. It reminds us to look at the whole: the chosen ingredient, its preparation and the combinations that make up the finished product.
Concentration
A concentration becomes meaningful alongside the amount taken per serving. Our product pages provide both measures to help you read the bottle and compare formulas.
Bioavailability
What happens to an ingredient once you take it? Digestion and absorption are among the questions we examine, taking into account the preparation studied.
Combinations
Some bottles bring several ingredients together. The composition and quantities help explain each combination and its place in the formula.

Discover Collagen HA Omega
Marine collagen meets hyaluronic acid, curcumin and cofactors in a single liquid formula. A composition to explore ingredient by ingredient.
Interested in liquid collagen? Start with the guide to understand the terminology and what to look for, then find the quantities and directions on the Collagen HA Omega product page.
Eating, sleeping, moving, recovering: these fundamental needs come before choosing a bottle. A supplement can find its place on that foundation. This is where our formulation work begins: understanding an ingredient, developing its preparation, adjusting its concentration and building coherent combinations. And continuing to explore everything that comes before the bottle.
Featured analyses
Intermittent fasting and protein pacing: a closer look at visceral fat
In an eight-week trial involving 41 adults with overweight or obesity, intermittent fasting combined with strategically distributed protein intake led to a greater reduction in visceral fat than conventional calorie restriction. The proportion of lean mass also increased more — which does not mean muscle was gained. We examine these results, the roles of fasting and protein, and the study’s industry funding.

Catherine Vasseur: physiology first
From forage to ease of movement, from metabolic imbalances to PPID — equine Cushing’s disease — Catherine Vasseur’s work teaches us to consider the horse as a whole. Changes in ACTH reported in some follow-ups, and stories as remarkable as that of Vénus, have helped our approach evolve. These experiences, accompanied by veterinary monitoring, inform our hypotheses and questions for future clinical research. Observing, documenting, questioning: the next steps also begin in the field.
