How it works, and everything we have written down
The making of the water, six free calculators, a four-week Indian diet plan, guides to every kind of functional water, and the questions people actually ask before their first bottle.
Better hydration, already inside
No pills, no powders, nothing to mix. Three steps from water to the bottle you open.
Pure water first
Every batch starts as packaged drinking water put through multi-stage purification and pH balancing — the clean canvas everything else depends on.
The formulation goes in
Vitamins, minerals, electrolytes and plant extracts are dosed and blended into the water itself at bottling — fully dissolved and evenly distributed.
Open and drink
No sachet, no cap to twist, no measuring. Every sip carries the same formulation, and the water still tastes like water.
The full story — why we make it and what goes in.
Guides, by water
One page per kind of functional water — what it is, what the actives do and who it suits. Each wears the colour of the bottle it is about.
Start from a goal
If you know what you want to change but not which bottle does it. Every goal below already has an answer attached.

Free, no signup. The BMI one uses Indian cut-offs rather than the global scale, and the water one accounts for an Indian summer — because most calculators do neither.

Before your first bottle
The four questions people ask most. Anything else — ask us directly.
- Do I have to mix anything in?
- No. The formulation is already infused into the water at bottling — fully dissolved and evenly distributed. You open the bottle and drink it.
- Does it taste like a health drink?
- It is colourless, flavourless and sugar-free. The actives are dosed at levels that dissolve clean, so the water tastes like water.
- How often should I drink it?
- Once a day is the pattern most of the formulations are built around, alongside your normal water. Each product page carries its own guidance.
- Is this a medicine?
- No. Amaayu is a packaged functional beverage. It supports normal function alongside a balanced diet — it does not diagnose, treat, prevent or cure anything.
