Built For The Breaking Point
On mile 47 of a 62-mile ultra, the aid station felt like a graveyard — empty cups, melting ice, and runners staring into space wondering how they’d hold it together. Your legs pulsed with heat, your vision narrowed, and for the first time all day, you felt your mind slipping before your body did. You reached for the HYK packet you’d been saving. The powder hit the water, and minutes later the fog began to break — not from sugar highs or sloppy caffeine spikes, but from clean hydration, sharp focus, and the steady engine HYK was built to ignite when everything else falls apart.
By mile 55, the trail was littered with people grabbing anything to survive — soda, pretzels, whatever kept them upright. But you were steady. Calm. Almost defiant. HYK’s electrolytes kept your legs firing, L-theanine kept your head clear, and clean caffeine carried you toward the next climb. HYK isn’t made for trends or pretty gym lighting; it’s made for the quiet, lonely miles when quitting feels easier than continuing. Out there, HYK isn’t just a drink mix — it’s the moment you realize you’re still capable of more.

How HYK is built different?
What makes HYK different from other hydration brands?
HYK is built for endurance athletes. Every formula is scientifically backed and dosed to perform - no fluff, no marketing BS, no "proprietary blends", no label confusion. We use real electrolytes, amino acids, and focus-enhancing ingredients that actually work.
What's the difference between HYK Original and HYK Essentials?
HYK Original is built for endurance - packed with electrolytes (1,00mg sodium), caffeine, nootropics, and recovery ingredients to power your body and sharpen your mind through long runs, races, or high-output efforts. HYK Essentials is your pure hydration formula - no caffeine, no extras, just perfectly balanced electrolytes (400mg sodium) and minerals for clean, efficient hydration any time of day.
How many electrolytes do I lose in sweat during 1 hour of intense exercise?
Most athletes lose between 500-1,500mg of sodium per hour - plus potassium, magnesium and other key electrolytes. Most hydration mixes don't come close to replacing what's lost. HYK Original gives you 1,000mg of sodium from pure sea salt plus the supporting electrolytes your body actually needs to stay balanced, prevent cramping, and keep performance steady.
Why is pure sea salt better than the table salt most hydration brands use?
Pure sea salt delivers more than just sodium — it contains trace minerals like magnesium, calcium, and potassium that work together for deeper hydration and muscle function. Table salt, on the other hand, is stripped down, chemically processed, and often loaded with additives. HYK uses premium sea salt because your body deserves clean, complete electrolyte replenishment, not the cheap stuff.
What makes HYK Original so great?
HYK Original isn’t just a hydration mix — it’s full-system fuel. Each serving delivers powerful electrolytes and BCAAs for endurance, natural caffeine from green tea for energy, and nootropics like L-theanine, tyrosine, and Alpha GPC for laser-sharp focus. It’s hydration, energy, focus, and recovery all in one — designed to keep you locked in, mile after mile.
What makes HYK Essentials so great?
HYK Essentials is clean, efficient hydration — nothing more, nothing less. Each serving delivers 400mg of sodium from pure sea salt, 150mg of potassium, and 60mg of magnesium — the perfect ratio to keep your body balanced and your muscles firing. It also features our Advanced Absorption Formula, powered by zinc and vitamins C & D, to help your body absorb electrolytes faster and more effectively. No caffeine, no fillers — just pure hydration that works as hard as you do.
