Built on What Your Body Actually Needs.
Three electrolytes. One amino acid. Dosed to match what nutritional science identifies as the targets for optimal performance. No guesswork.
Key Principle
"Replace what you lose before you feel the loss. That's the whole game."
Water Alone Doesn't Cut It.
Your body is about 60% water, but it doesn't operate on water alone. Electrolytes — electrically charged minerals — govern nearly every process that matters when you're performing: fluid balance, nerve signalling, muscle contraction, and cellular energy production.
When you sweat, you lose both water and electrolytes. Replace only water and you dilute the electrolytes remaining, which can actually worsen performance and, in extreme cases, lead to hyponatremia (dangerously low sodium). Replacing both is the only approach that works.
A loss of just 2% of body weight through sweat can reduce aerobic performance by up to 20% and impair cognitive function measurably.

01 · Electrolyte
Sodium · 1000mg
The Primary Electrolyte. The One You Lose Most Of.
Sodium is the most abundant electrolyte in your extracellular fluid and the primary electrolyte lost through sweat. It's the linchpin of fluid balance — it governs how much water your kidneys retain and how effectively fluid moves between cells. Without adequate sodium, water can't stay where your body needs it.
Sweat sodium concentration varies between individuals (roughly 460–1840mg per litre), but most athletes training at moderate to high intensity will lose between 600mg and 1500mg of sodium per hour. WILDER provides 1000mg per stick — placed squarely in the optimal replenishment zone for a single-serve product.
Daily Target
For athletes in moderate–high training loads.
Lost in Sweat
Average loss per litre of sweat during exercise.
Primary Role
Holds water in the right compartments for performance.
02 · Electrolyte
Potassium · 600mg
Every Rep, Every Stride — Potassium Fires the Signal.
Potassium is the dominant electrolyte inside your cells. It works in tandem with sodium across cell membranes to generate the electrochemical gradient that powers nerve impulses and muscle contractions. Without it, muscles can't fire efficiently — and they fatigue faster.
Low potassium (hypokalemia) is closely associated with muscle weakness, cramping, and irregular heart rhythm. While potassium loss through sweat is lower than sodium — roughly 150–500mg per litre — cumulative daily loss from exercise can be significant. The optimal daily intake for active individuals is 3.5–5g. WILDER's 600mg per stick makes a meaningful contribution toward that target.
Daily Target
Optimal daily intake for active individuals.
Primary Role
Powers every contraction from first rep to last.
What Low K Causes
Weakness, cramping, early fatigue under load.
03 · Electrolyte
Magnesium · 100mg
The Quiet Enforcer. Involved in 300+ Reactions in Your Body.
Magnesium is a cofactor in over 300 enzymatic reactions — including protein synthesis, muscle contraction, nerve function, and energy production. It's also responsible for muscle relaxation: it's the mineral that tells a contracted muscle to let go. When magnesium is depleted, muscles are more prone to cramping and slower to recover.
Intense exercise increases magnesium excretion through both sweat and urine. Studies suggest that athletes may require 10–20% more magnesium than sedentary individuals. The optimal daily range is 400–600mg. WILDER contributes 100mg per stick — a meaningful top-up on top of dietary intake, particularly for those training daily.
Enzymatic Reactions
Magnesium is involved in more biochemical processes than any other mineral in this formula — from the ATP your muscles burn to the protein your muscles repair with afterward.
04 · Amino Acid
L-Theanine · 40mg
Calm, Sharp Focus. No Stimulants Required.
L-Theanine is an amino acid found naturally in green tea. It promotes alpha brain wave activity — the same mental state associated with calm alertness and flow states — without causing drowsiness or the jitter-crash cycle of caffeine. It's why experienced tea drinkers describe a different quality of focus compared to coffee: present, steady, undistracted.
At 40mg per serving, WILDER uses a dose that research associates with relaxed attentiveness — enough to take the edge off mental fatigue and support decision-making during training, without any reliance on stimulants. Zero caffeine. Zero crash. Just a cleaner signal.
What It Does
- Promotes alpha brain wave activity
- Reduces subjective stress without sedation
- Supports cognitive flexibility during fatigue
- No tolerance build-up over time
What It Doesn't Do
- Stimulate the central nervous system
- Raise heart rate or blood pressure
- Cause an energy crash
- Interact with sleep when taken pre-workout
Heat and Humidity Change Everything.
Training at 28–34°C with 70–90% humidity isn't like training in a temperate gym. Your body's cooling system works harder — and loses far more than most standard hydration advice accounts for.
Higher Sweat Rates
Athletes training in tropical heat can sweat 50–100% more than in temperate conditions at the same intensity — meaning electrolyte losses scale proportionally.
Ambient Temperature
Above 28°C, heat dissipation through sweating becomes the primary cooling mechanism. Humidity above 60% reduces sweat evaporation efficiency, compounding the load on cardiovascular and thermoregulatory systems.
The Right Timing
Electrolytes absorbed 30–60 minutes before activity are available when you need them most. Taking them after depletion means playing catch-up against an already degraded system.
Standard hydration advice — "drink 8 glasses of water a day" — was not designed for someone training outdoors in Southeast Asian humidity. Tropical athletes need a different baseline: electrolyte-forward, sodium-led, and timed to match how hard they actually train.
The Dose-Response Relationship Is Well Established.
The relationship between hydration status and physical performance is one of the most replicated findings in sports science. The effects are not subtle — even modest dehydration produces measurable declines across aerobic capacity, strength, reaction time, and decision-making.
The brain is particularly sensitive: cognitive performance — attention, working memory, executive function — begins to decline at fluid losses that have almost no physical symptoms. For athletes whose performance depends on reading a game, timing a move, or holding a pace, this matters as much as muscular endurance.
Body Water Loss
Elevated core temperature. Heart rate begins to rise above baseline for the same effort output.
Body Water Loss
Aerobic capacity reduced up to 20%. Cognitive performance measurably impaired. Most people still feel "okay."
Body Water Loss
Significant strength loss. Heat exhaustion risk. Mandatory stop for elite athletes under competition protocols.
