The Science

Engineered for the conditions that exist at 35,000 feet

Stratolyte's formulation is built around the specific physiological demands of pressurised aviation environments — not borrowed from sports hydration or general wellness.

Cabin Environment

What happens to your body at altitude

Aircraft cabins are pressurised to simulate altitudes of roughly 6,000–8,000 feet — not sea level. The air recirculated through the cabin is drawn from outside and is extremely dry.

At these humidity levels, the body's moisture loss accelerates through respiration alone. A passenger on a long-haul flight can lose 1.5–2 litres of fluid without noticing significant thirst — the standard thirst mechanism is suppressed at altitude.

"Thirst is a lagging indicator. By the time you feel it, dehydration is already impairing cognitive and physical performance."

For crew working 8–14 hour shifts in this environment, the cumulative effect is significant: impaired focus, slower recovery, increased fatigue. Water alone cannot compensate — electrolyte balance is disrupted independently of fluid intake.

Formulation

An altitude-optimised electrolyte system

Each 5g sachet is engineered to restore the electrolyte balance disrupted by pressurised cabin conditions — not to replicate sports hydration, which addresses different physiological states.

Sodium
Primary electrolyte
Regulates fluid retention and absorption. Elevated relative to ground-level formulations to compensate for the accelerated respiratory losses at altitude.
Potassium
Cellular function
Supports nerve signalling and muscle function. Altitude-induced dehydration depletes potassium disproportionately, contributing to fatigue and cognitive fog.
Magnesium
Recovery & stress response
Involved in over 300 enzymatic processes. Supports recovery from physical and cognitive stress — particularly relevant for cabin crew on extended duty.
Calcium
Structural balance
Works in concert with magnesium to maintain muscular and neural stability throughout the flight cycle.
Vitamin C
Immune & antioxidant
Recirculated cabin air concentrates airborne particles. Vitamin C supports immune readiness for passengers and crew on high-frequency flight schedules.
B-Complex
Energy metabolism
B vitamins support cellular energy production and help buffer the fatigue associated with circadian disruption and sustained altitude exposure.
Protocol

Three moments. One system.

01 · Pre-Flight · Prepare
Before boarding
Pre-loading electrolytes 30–60 minutes before boarding prepares the body's fluid balance before cabin humidity begins its work. This is the most under-utilised window in passenger and crew preparation — and the most impactful.
02 · In-Flight · Maintain
During the flight
Dissolved into water and consumed at the 2–3 hour mark on medium to long-haul routes. Maintains electrolyte balance during the period of peak humidity stress — when the cabin environment is fully established and respiratory losses are at their highest.
03 · Pre-Landing · Recover
Descent to arrival
A final sachet consumed 60–90 minutes before landing primes the body for the transition back to standard atmospheric conditions. Passengers arrive sharper. Crew end their shifts in better condition.
"Not a beverage — a repeatable, measurable system."

Per sachet. Dissolves in any water. No hardware required.
