Here is a physiological reality that most of us overlook: two individuals can drink exactly the same amount of water on the same day and display very different levels of cellular hydration.
Not because one drinks better than the other. But because effective hydration cannot be reduced to a volume. It depends on what the water carries and on how the body can actually absorb, retain, and utilise it.
Water is no longer merely H₂O. It has become a subject of formulation.
What Physiology Tells Us
Water absorption in the small intestine relies largely on an active transport mechanism: the SGLT1 cotransporter. When sodium and glucose are simultaneously present, they activate this transporter and water follows by osmosis. This is the principle behind the oral rehydration solutions developed by the WHO since the 1970s, which some have described as "the greatest medical advance of the twentieth century".
In practice: drinking plain water does not activate this system. Without electrolytes, water can pass through the body without being fully absorbed at the cellular level.
Each mineral plays a distinct role. Potassium maintains intracellular fluid balance. Magnesium acts as a cofactor in more than 600 enzymatic reactions, and its bioavailability varies according to its chemical form: organic forms (citrate, glycinate, malate) are significantly better absorbed than inorganic forms. Calcium contributes to cellular signalling and membrane integrity.
This is no longer a question of quantity. It is a question of composition.
Robertet: 175 Years of Expertise in the Service of Functional Hydration
Formulating a properly remineralised water or an electrolyte-based drink is not something that can be improvised. It requires mastery of chemical forms, mineral interaction ratios, and active ingredient stability as well as impeccable traceability for every ingredient.
This is precisely the expertise that the Robertet Group brings to Sküma Water.
Founded in Grasse more than 175 years ago, Robertet is the world leader in natural extracts. Grasse, the birthplace of perfumery and botanical extraction, is not a minor detail: it is where, century after century, the techniques for isolating natural actives with pharmaceutical-grade analytical precision were developed. What Robertet masters is the transformation of living matter into functional ingredients: documented, traceable, and optimised.
Through Villa Blu, its accelerator dedicated to natural and wellness startups, Robertet co-develops with Sküma Water along two concrete lines: the remineralisation of purified water via MY™ Bases (selection of mineral forms, physiological ratios), and the development of MY™ Boosters, solutions combining electrolytes and natural actives formulated to precisely activate the intestinal absorption mechanisms documented by research.
Ingredients not chosen to impress. Selected to perform.
To Formulate Is to Choose
Creating a high-performance hydration booster today resembles developing a functional nutrition product. The parameters to be mastered simultaneously: mineral ratios, bioavailability, osmolarity, stability of active ingredients, sensory experience. A solution that is too concentrated can have the opposite effect, drawing water out of cells by osmosis. Equally, a product one does not want to drink cannot fulfil its function, regardless of its physiological quality.
This is why hydration has moved beyond the status of a commodity product to become a fully-fledged functional category.
In Conclusion
The Sküma Water approach is built on a straightforward conviction: purify water thoroughly, then rebalance it with the right minerals, in the right forms, at the right ratios. An approach complemented by cellular hydration boosters, to offer a complete hydration solution adapted to everyday needs. With Robertet as a formulation partner, this conviction draws on 175 years of rigour in natural materials.
Because what we drink every day deserves the highest standard of excellence.
