THE PROBLEM

You don't have jet lag.
You have flight drain.

Most people blame time zones, but most of it is the cabin quietly draining you for eight hours. Here is the whole story in one chart.

AIRLINE PILOT · CO-FOUNDER, MACH
MEET THE CREW
“Throughout my flying career, I have always taken my health and performance seriously.

What frustrated me was that nothing available felt designed for the realities of air travel. Electrolytes made for the gym. Energy drinks built around caffeine. Sleep products that did not fit long flights, changing time zones and disrupted routines.

Those challenges are not limited to pilots. They are felt by anyone who flies, whether for work, for adventure or simply to get somewhere that matters. Flying places a unique strain on the body and mind, and we believed travellers deserved a more considered solution.

That is why we created Mach: purposeful formulas designed around life in the air, tested across real flights and real rosters, and made for everyone who wants to travel sharper and recover better.”

HOW TO TAKE IT

Ten seconds. Any cabin. Any cup.

1

Tear

One stick from your passport wallet. Powder is not a liquid, so it clears any security lane.

2

Pour

Into 500ml of water. The free cup from the trolley works. No shaker, no stirring.

3

Drink

Sip over ten minutes. Slower intake, better absorption, fewer aisle trips.

WHEN TO TAKE IT

The cabin lights are dimming.

Notice the page? It dims as you scroll, the same way an overnight cabin does. RESTORE is built for exactly that moment.

01
AFTER TAKE-OFF

Lights dim

One stick in 500ml as the service ends. Rehydrate before sleep, not instead of it.

02
MID-SECTOR

While you sleep

Glycine, magnesium, lemon balm and L-theanine support restorative sleep — no sedatives, no melatonin.

03
ON ARRIVAL

In the hotel

One before bed on night one. The difference between a lost first day and a normal one.

WHY WE ONLY DO FLIGHT

Every other electrolyte is built for the gym.
This one is built for seat 34K.

Sweat loss and cabin loss are different problems. A gym formula assumes you are losing salt through sweat and burning fuel, so it loads carbs and flavouring. A cabin formula has to work in dry, pressurised air, on a still body, without sugar, without caffeine, and without bloat at altitude. We formulate for one environment, and it is the one you are in when you read the seat pocket card.

CABIN FORMULATED • NOT THE GYM • MACH • ✈

Before you board

Yes. MACH is a dry powder, so the 100ml liquids rule does not apply. The stick is sized to sit in a passport wallet.
Formulation, not flavour. Cabin air at cruise sits at 10 to 20% humidity, so you lose water faster through breath and skin while sitting still. RESTORE pairs a full electrolyte dose with an evening blend of glycine, magnesium, lemon balm and L-theanine — no sedatives, no melatonin.
RESTORE is the wind-down stick. One after boarding on an overnight sector, or in the hotel before sleep on arrival.
A box lands every month. Skip, pause or cancel any time from your account, no minimum term.

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.
