The 10 essential actives in AUA: what they do in your body
by L'équipe AUA Hydrate
When you read the composition of a food supplement, you see Latin names, figures and percentages scroll past. But behind every line sits a precise biological mechanism. Here, for each of the 10 actives in AUA Hydrate, is what it actually does in your body — and why you need it.
The 4 main electrolytes
Potassium (192 mg — 4% NRV)
Potassium is the main ion inside your cells. It maintains osmotic balance, regulates nerve transmission and takes part in muscle contraction (including that of the heart). A deficiency often shows up as cramps, diffuse tiredness and sometimes heart rhythm disturbances.
Sodium (184 mg — 8% NRV)
Often seen as an enemy because of high blood pressure, sodium is in fact essential to hydration. Without it, water does not stay in your tissues. The modern problem is not excess sodium as such, but the sodium hidden in processed foods. Clean sodium, at a physiological dose as in AUA, is on the contrary beneficial.
Magnesium (26 mg — 6% NRV)
The great forgotten mineral of the Western diet. More than 300 enzymatic reactions depend on magnesium. It is involved in energy production (ATP), muscle relaxation, sleep quality and stress regulation.
Chloride (284 mg — 12% NRV)
Less well known, chloride is nonetheless the indispensable partner of sodium and potassium in maintaining the balance of body fluids. It also contributes to producing the gastric acid needed for digestion.
The supporting minerals
Calcium (49 mg — 4% NRV)
Beyond bone health, calcium is a direct player in muscle contraction and blood clotting. It works in synergy with magnesium: too much of one without the other creates an imbalance.
Phosphorus (32 mg — 2% NRV)
Phosphorus works with calcium for bone health, but it is also an essential component of ATP (the “energy currency” of your cells) and of cell membranes.
The strategic trace elements
Zinc (2.7 mg — 25% NRV)
Zinc is a cofactor for more than 200 enzymes. It supports immunity, wound healing, energy metabolism and testosterone production. A deficiency shows up as greater vulnerability to infection and persistent tiredness.
Chromium (55 µg — 160% NRV)
Chromium contributes to normal carbohydrate metabolism and to maintaining stable blood glucose. Particularly useful for anyone who feels an energy slump after meals.
The key vitamins
Vitamin C (115 mg — 130% NRV)
The best-known natural antioxidant, vitamin C protects your cells from oxidative stress, supports immunity and improves iron absorption. Being water-soluble, it is not stored by the body — so a daily intake is needed.
Vitamin B12 (130 µg — 5420% NRV)
Essential to the formation of red blood cells and to the proper working of the nervous system. B12 matters particularly for vegan and vegetarian diets. The high NRV percentage may come as a surprise: B12 has a narrow absorption window (±1% by mouth), so what looks like an overdose is in reality a physiological dose matched to the pharmacokinetics.
Synergy: why a complete formula matters
What makes AUA Hydrate worthwhile is not a single active, but the synergy between them. Potassium works better with magnesium. Calcium is absorbed better with vitamin C. Sodium governs how effective potassium is. It is this logic of synergy, rather than the hunt for a miracle active, that guides our approach.
