Most electrolyte powders fall into one of two camps: underdosed formulas that taste like flavoured water, or mega-dose sodium bombs that churn your stomach the moment you add a gel.
Pillar Performance Electrolyte Hydration sits in neither. It delivers a precise, evidence-based electrolyte profile - 400mg sodium, 190mg potassium, and 80mg magnesium per 7g serve - at a hypotonic concentration of roughly 100–130 mOsm/kg. That means it absorbs faster than your blood plasma, getting fluid into cells where it actually matters rather than sitting in your gut.
Who is this for?
Endurance runners, cyclists, triathletes, CrossFit athletes, and anyone training hard enough that plain water stops cutting it. It is equally effective as an everyday hydration base for people working outdoors, travelling, or simply trying to stay sharp through long days. The formula is designed to be stacked alongside energy gels and carbohydrate drinks during long sessions - because the 400mg sodium dose keeps the combined osmolarity in the isotonic range, unlike 800–1,500mg competitors that tip into hypertonic territory and slow absorption when paired with fuel.
Why the sodium dose matters
Sodium is the electrolyte you lose fastest through sweat. But more is not better. At doses above 800mg per serve combined with carbohydrates, osmolarity climbs past 300 mOsm/kg, pulling water into the gut instead of your bloodstream. That is the mechanism behind the cramping, bloating, and nausea athletes experience mid-race. Pillar's 400mg dose is calibrated to trigger active sodium-glucose co-transport across the intestinal wall - the fastest natural hydration pathway - without the GI penalty.
Key specs at a glance
Sodium: 400mg per serve | Potassium: 190mg per serve | Magnesium: 80mg per serve | Energy: approximately 22.8 kJ per serve | Sugar: zero added | Sweetened with monk fruit and stevia | Naturally flavoured | Hypotonic formula (~100–130 mOsm/kg) | Informed Sport Certified (every batch tested for WADA banned substances) | Vegan, gluten-free, dairy-free, nut-free, soy-free, egg-free
Available sizes
210g tub — 30 serves. Best value for daily use and home training.
15 x 7g stick packs — single-serve sachets. Built for race day, travel, and gym bags.
How to use
Mix 1 serve (7g) into 500–750ml of cold water and shake or stir until dissolved. Use before, during, or after training to replace sweat losses and maintain fluid balance. Works as a daily hydration drink first thing in the morning or on hot days. Do not exceed 4 serves per day.
Frequently asked questions
Can I use this with energy gels during a race?
Yes - this is a core design advantage. Because the sodium dose sits at 400mg rather than the 800–1,500mg found in many competitors, combining it with a standard energy gel keeps the total osmolarity in the isotonic range (approximately 289 mOsm/kg), so absorption stays fast and your stomach stays settled.
Is this suitable for drug-tested athletes?
Every batch of Pillar Electrolyte Hydration is Informed Sport Certified, meaning it has been tested by an independent lab for substances prohibited in sport under the WADA code. If you compete in a drug-tested environment - from club-level athletics to professional sport - this is cleared for use.
How is this different from a standard sports drink?
Standard sports drinks are typically hypertonic (high sugar, high osmolarity), designed to deliver energy rather than hydration. Pillar is hypotonic - lower osmolarity than your blood plasma - which means it prioritises fluid absorption speed. If you need calories during exercise, use a gel or fuel source separately and sip this alongside it.
Is it suitable for daily use outside of training?
Completely. The low-calorie, zero-sugar formula works as an everyday hydration drink. Most people wake up mildly dehydrated, so a serve first thing in the morning is a practical daily habit.
