Hydration isn’t one-size-fits-all. Test it.


Lose too much sodium and you cramp. Lose less than you think and you're wasting money on drinks you don't need. Either way, you're guessing.

Know your number.

Sodium loss • One test only • No more guessing.

« Before this test

You know you sweat a lot, but you do not know what it means. You drink sports drinks without knowing which ones actually help or how much you need. In the heat, things fall apart. Cramps creep in. Training feels harder than it should.

After this test »

You know exactly how much sodium you lose per litre of sweat. That number is genetic and it rarely changes. With that clarity, you build a hydration strategy that fits you. Training quality improves. The risk of cramping drops. And race day feels more controlled.

How the test works

  • Sweat Stimulation

    This test doesn't require any exercise. We simply stimulate your sweat glands via your forearm for roughly 5 minutes, to allow us to move on to the collection stage. The most you feel is a mild tingling sensation.

  • Sweat Collection

    This is the fun part, when we move onto applying a sweat duct to your arm, in order for us to collect a small sample. Once done, we can then analyse this for its sodium concentration.

    Hydration Strategy

    From there, we calculate your genetic sodium loss per litre of sweat, and design a hydration & fuelling plan for your next goal or event, so you know what to drink, how much, and when.

FAQ

Are you the only official Precision Fuel & Hydration sweat test centre here in Singapore?

Yes thats correct. We have been partners now for over 7 years helping people fuel and hydrate better!

Do I need to exercise during the test?

No. Sweat testing is completely non-invasive and does not require you to exercise. We stimulate your sweat glands with mild electrical currents and capture the sweat directly from your forearm.

How accurate is the test?

Very accurate. Sodium concentration in sweat is genetically determined and does not change. Once you know your number, it’s yours for life.

What if I already use sports drinks or electrolytes?

Bring them along. We’ll review their sodium content against your results and adjust your hydration strategy to make sure you’re getting the right balance.

Will this stop my cramps?

Cramps are complex and can have multiple causes, but sodium imbalance is a major factor. Understanding your sodium loss and adjusting your hydration makes cramps far less likely.

Do I need to re-test in the future?

No. Unlike fitness metrics that change with training, your sweat sodium concentration generally stays the same. One test is enough to set you up.

Is this just for hot-weather athletes?

No. Even in cooler conditions, poor hydration can limit your performance and recovery. But if you race or train in the heat, a tailored hydration plan is even more critical.
