THE SCIENCE OF FLIGHT DRAIN

The cabin is an environment.
We are the only ones formulating for it.

Every electrolyte on the shelf was designed for one scenario: a sweating body at sea level. A pressurised cabin at 38,000ft is a different physiological problem with different losses, different mechanisms and different requirements. This page sets out what goes into every stick, what we deliberately leave out, what the cabin actually does to you, and why the standard fixes fall short.

ELEVATE.

Calm focus without caffeine.

MACH ELEVATE pack
Electrolyte baseCabin-dose sodium, potassium and magnesium for fluid retention
TaurineSupports cognitive performance under mild hypoxia
CiticolineSupports attention and mental energy
L-theanineSmooths focus, no jitters and no crash
GingerSettles the stomach through turbulence and travel

SUGAR FREE · ZERO CALORIES · NO CAFFEINE

HYDRATE. UNWIND. RECOVER. · BERRY DREAM · 8G STICK

RESTORE.

Recovery without melatonin.

MACH RESTORE pack
Electrolyte baseOvernight rehydration while you sleep, not instead of it
GlycineSupports sleep quality and next-day freshness
MagnesiumSupports muscle relaxation and normal sleep function

SUGAR FREE · NO SEDATIVES · NO MELATONIN

THE CLEAN LABEL

Everything it needs.
Nothing it does not.

Both formulas are built clean from the label down: functional ingredients at meaningful doses, and none of the padding that usually fills out a flavoured drink mix.

0GRAMS OF SUGAR
0CALORIES
A clean, short label where every ingredient has a job to do
No artificial flavours
No artificial colours
No preservatives
No caffeine, no sedatives, no melatonin — nothing that costs you later in the flight
Made in Britain

IF IT DOES NOT EARN ITS PLACE IN THE STICK, IT IS NOT IN THE STICK.

PART TWO · THE ENVIRONMENT

Four things the cabin does to you.

These are not edge cases. They happen on every pressurised flight, to every passenger, on every sector.

01
10 to 20%
CABIN HUMIDITY AT CRUISE, DRIER THAN THE SAHARA
The air is stealing your water every time you breathe.
Cabin air is drawn from outside at altitude, where it holds almost no moisture, and it replaces the cabin volume every few minutes. Every breath out carries water the air will not give back, and your skin loses moisture to the same dry air continuously. This is insensible loss: it never registers as sweat or thirst, so nothing prompts you to replace it.
Two hours in, you are already behind.
02
8,000FT
EFFECTIVE CABIN ALTITUDE, YOU NOT THE PLANE
Your body spends the flight up a mountain.
Cabins are pressurised to the equivalent of 6 to 8,000ft, not sea level. Mild hypoxia at that altitude raises your breathing rate and can trigger increased urine output, both of which accelerate fluid loss. It is also why alcohol lands harder and why a dull cruise headache is so common. Ben Nevis is 4,400ft. You are living above it for eight hours.
Faster breathing into drier air is compounding loss.
03
0L
LOST PER LONG HAUL, A LARGE BOTTLE OF WATER
You lose it without ever feeling thirsty.
Cool, dry air blunts the thirst response, and sitting still removes the cues that normally prompt drinking. Most passengers replace roughly a third of what they lose. The gap between what leaves and what you replace is what you feel on landing: the taxi headache, the puffy face, the fatigue after a day of sitting down.
Dry air switches your thirst alarm off. That is the trap.

FLUID COST OF ALCOHOL AT ALTITUDE
The free G&T counts double against you.
Alcohol and caffeine are diuretics, and the effect of alcohol is compounded at cabin altitude, where it also disrupts sleep quality more than it does on the ground. On top of a body that is already running a fluid deficit, one drink does the damage of two.
One MACH per drink keeps the books level.
PART THREE · WHY WATER ALONE FAILS

Water leaves as fast as it arrives.

Your body retains fluid using electrolytes, chiefly sodium, which regulate where water goes and whether it stays. Plain water without electrolytes dilutes the blood, your kidneys read that as a surplus, and much of what you drink passes straight through. That is why you can drink cup after cup on a flight, visit the toilet all sector, and still land dehydrated.

FLUID RETENTION IN A CABIN ENVIRONMENT
0%

Clinical studies found up to 71% higher fluid retention when drinking an electrolyte solution rather than mineral water in an aircraft cabin. Same volume drunk. Very different amount kept.

THE ELECTROLYTES ARE NOT A FLAVOUR. THEY ARE THE MECHANISM.

PART FOUR · THE WRONG TOOL

Sweat loss and cabin loss are different problems.

Gym electrolytes are not bad products. They are the right answer to the wrong question. Here is the difference an environment makes.

THE GYM PROBLEM · WHAT THEY SOLVE
MECHANISMHeavy sweating during intense exercise
WHAT GOESWater plus large amounts of sodium lost through skin
BODY STATEWorking hard, burning fuel, heart rate up
SO THEY ADDBig sodium doses, sugar and carbs for energy, often caffeine
ON A PLANEYou are not sweating or burning fuel, so you get the sugar, the bloat and the stimulants without the need
THE CABIN PROBLEM · WHAT MACH SOLVES
MECHANISMBreath and skin loss to extremely dry, pressurised air
WHAT GOESWater steadily, with no thirst signal to prompt replacement
BODY STATEStill, at mild altitude, often sleep deprived and jet lagged
SO WE ADDA full electrolyte dose for retention, plus sector-specific blends for focus or recovery
AND LEAVE OUTSugar, calories, caffeine, sedatives and melatonin. Nothing that costs you later in the flight
Made in Britain Sugar free, zero calories No caffeine, no melatonin Dry powder, clears security Created by airline pilots
THE SHORT VERSION

The cabin takes around 1.5 litres from you.
The Solution?
One sachet per sector.

BEFORE YOU BOARD

Questions, answered.

Everything about the formulas, flying with MACH, and how orders work. If we have missed something, ask us. Q1: How do I use these supplements during my trip? Simply mix one sachet into 300–500ml of water. Use the Focus & Hydrate formula prior to departure or during daytime flight hours when you need to stay alert and hydrated. Take the Wind Down formula 30–60 minutes before you plan to sleep on an evening flight or upon settling into your hotel. Q2: Can I take both formulas on the same long-haul journey? Yes, they are designed as a complete day-to-night travel system. Many passengers take Focus & Hydrate during the first half of a long-haul flight, then switch to Wind Down when preparing for rest before landing. Always follow the recommended daily intake on each packet. Q3: Are these sachets compliant with airport security rules? Yes. Our supplements come in individual dry powder sachets, making them completely compliant with UK Civil Aviation Authority (CAA) and international liquid restrictions. You can take them through security empty-handed and mix them with water once airside or on board. Q4: Will the daytime Focus formula make me feel jittery or anxious? Not at all. The Focus & Hydrate formula is 100% caffeine-free. It provides sustained mental clarity and tiredness reduction using essential B-vitamins (B5, B12), Vitamin C, and electrolyte minerals rather than heavy stimulants. Q5: Will the evening formula cause grogginess when I wake up? No. Wind Down uses gentle, non-sedative nutrients such as Magnesium Glycinate, Vitamin B6, and Lemon Balm Extract to support normal nervous system function and natural relaxation, allowing you to wake up clear-headed. Q6: Why is Magnesium Glycinate used in the evening formula? Magnesium Glycinate is a highly bioavailable form of magnesium bound to the amino acid glycine. It is exceptionally gentle on the stomach compared to cheap forms (like magnesium oxide) and supports normal muscle function and psychological well-being. Q7: Are your products vegan and free from major allergens? Yes. Both formulas are 100% suitable for vegans and vegetarians, non-GMO, and free from gluten, dairy, soy, and artificial colors or preservatives. Q8: Why is ginger extract included in the pre-flight formula? Ginger root extract has been traditionally valued by travelers for centuries. We include it alongside our hydration blend to provide a crisp, refreshing taste and settle the stomach during flight. Q9: Can these supplements prevent or cure jet lag? No. Under UK food regulations, supplements cannot claim to prevent, treat, or cure jet lag or sleep disorders. Our products are formulated with authorized nutrients that contribute to the reduction of tiredness and fatigue and normal psychological function. Q10: Can I use these if I am pregnant or on prescription medication? If you are pregnant, breastfeeding, taking medication, or under medical supervision, we recommend consulting your GP or healthcare professional before introducing any new dietary supplement.
