The Science: The Sustained Effort Advantage
Sustained Effort & Output
Maintain Your Edge: By increasing oxygen availability, you maintain a higher level of output and performance for longer, ensuring you are still sharp and powerful in the final minutes of extra time.
Cramp & Fatigue Reduction
Push to the Very End: You delay the onset of fatigue and the build-up of lactic acid. Professional users report a significant reduction in late-game muscle cramping, ensuring you remain effective and in control.
Recovery Acceleration
Bounce Back Faster: The increased oxygenation supports quicker recovery after intense sessions, meaning you are ready for the next training session sooner.

Match Day Strategy
For full match dominance, professional players utilise a two-dose strategy:
Pre-Match: Take EI8HT Energy 15 minutes before kick-off. This sharpens focus and maximises your aerobic output for the crucial first half.
Half-Time: Take EI8HT Orginal during half time. This ensures your oxygen efficiency is sustained for the entire second half, delaying fatigue and preventing late-game cramping.
Training & Recovery:
Post-Workout Recovery: Use EI8HT Original after exercise to help accelerate muscle repair and support long-term endurance consistency.

How EI8HT Works: Backed by Science
EI8HT’s patented nanotechnology delivers a new level of cellular oxygen support — precisely when your body needs it most.
Nano-Scale Oxygen Delivery
EI8HT uses microscopic oxygen-filled particles, significantly smaller than red blood cells, to enable rapid and efficient oxygen transport to working muscles.
Bioavailable at the Cellular Level
Oxygen released by EI8HT is directly usable by mitochondria — the powerhouses of your cells — enhancing ATP production by up to 30% for sustained energy under stress.
Timed to Match High Demand
EI8HT activates around 80%+ max heart rate, targeting your oxygen deficit zone to delay fatigue and improve output during high-intensity efforts.
Supports Zone 2 & Endurance Training
Even at lower intensities (Zone 2: 60–70% max HR), increased oxygen efficiency of 5–8% supports fat metabolism, reduces lactate build-up, and boosts aerobic adaptation.
Independent of Red Blood Cell Count
EI8HT enhances plasma oxygen-carrying capacity without relying on red blood cells — delivering a unique boost in oxygen availability.
