THE ELECTROLYTE DOSED FOR THE SESSION. NOT THE MARATHON.

You chose this sweat. Base 250 replaces what a class or sauna actually takes out - 250mg of sodium, balanced with potassium and magnesium, zero sugar. No salt bomb. Nothing that undoes the work.

TOO SWEET, OR A SALT LICK.

Hydration powders come in two flavours of wrong for a studio session. The sugary ones drink like soft drink and undo the work you just did. The athlete mixes pack 1,000mg of sodium because they are built for hours of heavy sweat, and they taste like it. A reformer class or a sauna sit is real sweat - but it is not a marathon. You need something in between.

What a session actually takes

REAL SWEAT. SENSIBLE NUMBERS.

Estimated fluid lost per session. Estimates from published research. Everyone is different.
Reformer class (50 min) Modest - a glass or two of fluid
Sauna (15 to 20 min) Around half a litre to a litre
Hot yoga (60 min) Around 1 litre
Marathon-level training (per hour, for hours) 1 to 2.5 litres EVERY hour - what 1,000mg products are dosed for

AFTER A MODERATE SESSION, RESEARCH SUGGESTS A FEW HUNDRED MILLIGRAMS OF SODIUM IS THE SENSIBLE TOP-UP. NOT A THOUSAND.

Base 250 sits right in that range - 250mg of sodium with 250mg of potassium and 60mg of magnesium, so you put back what the session took without loading up on salt your day does not need.

Heavy 90-minute hot sessions take more out of you - that is what a second sachet is for.

Base 250 Berry sachet
Nothing that undoes the work

0g SUGAR. 250mg SODIUM. NO HEAVY FEELING.

You did not do 50 minutes of reformer to drink a soft drink's worth of sugar, and research links high-sodium intake with water retention and that puffy, heavy feeling. Base 250 is dosed low on purpose and balanced one-to-one with potassium - light, clean and easy to drink before or after class, sweetened with a touch of stevia.

Where it fits

BEFORE. AFTER. SAUNA.

Before class studio moment
BEFORE CLASS

One sachet in 500ml before the 6am reformer. Walk in topped up, not sloshing.

After class studio moment
AFTER CLASS

Stir one into cold water after a hot class to replace what you sweated out. Double up if it was a big one.

Sauna days studio moment
SAUNA DAYS

Sauna sweat is still sweat. A glass after the last round replaces the fluid and electrolytes you lost - nothing more dramatic than that.

WHAT'S IN EVERY SACHET.

250mg Sodium Replaces what you lose through sweat, dosed for a session not a marathon.
250mg Potassium Balanced one-to-one with sodium, the ratio the salt bombs skip.
60mg Magnesium Supports normal muscle and nervous-system function.
40mg Vitamin C A bonus antioxidant, along for the ride.
H2 Molecular Hydrogen Released when you stir, a bonus antioxidant the research is increasingly interested in.
0g Sugar None. Stevia-sweetened instead.
0 Calories Nothing to budget for.
A clean bonus

Every serve also releases molecular hydrogen (H2) when you stir it - an antioxidant the research is increasingly interested in. A bonus, not the point. The point is a sensible, session-sized top-up.

From the Founders

WE DOSED IT FOR THE SWEAT YOU ACTUALLY DO.

The big electrolyte brands dose for marathons and mine sites. But most of the sweating we saw around us was chosen - a reformer class, a hot room, a sauna. So we built Base 250 to match it: enough to replace a session, balanced so it drinks light, zero sugar so it never undoes the work.

If you sweat buckets, have two. That is still less salt than one scoop of the extreme stuff.

Lachlan - Co-founder & Managing Director, Fluence

Questions

The studio
answers

Is 250mg enough for a hot yoga class? +
For most classes, yes - research suggests a few hundred milligrams of sodium is the right top-up after a moderate session. For a long, heavy-sweat class (you know the one), have two sachets. That is the honest answer.
Will it bloat me like other electrolytes? +
It is dosed low on purpose. The heavy, puffy feeling people associate with electrolyte drinks tends to come with high sodium, and Base 250 is 250mg, balanced one-to-one with potassium.
What does it taste like? +
Light and clean. Not sweet like the sugary ones, never salty like the athlete mixes. Lightly flavoured, gently sweet from stevia, still water underneath.
Can I drink it on sauna days? +
Yes. Sauna sweat carries electrolytes out with it just like exercise sweat. One sachet in cold water after your last round replaces fluid and electrolytes. We will not promise anything more exotic than that.
Is there any sugar or anything artificial? +
0g sugar, zero calories, sweetened with stevia. Sodium, potassium, magnesium, vitamin C and natural flavour. The full label is above.
How does the subscription work? +
30 sachets delivered monthly at $1.93 per serve. Swap flavours between deliveries, skip a month, or cancel anytime.
What is the hydrogen thing on the label? +
Every serve releases a little molecular hydrogen when you stir - an antioxidant the research is increasingly interested in. A bonus, not the point.
