Why Use EI8HT Oxygen
EI8HT brings the power of oxygen directly to your cells, helping you push harder, recover faster, and perform at your peak. Our cutting-edge nanotechnology, developed with Oxford University, increases oxygen availability precisely when you need it most—at peak exertion.
Boosts Energy with Oxygen
Feel more powerful during intense workouts with an increased 6.6%* output. EI8HT delivers oxygen-enhanced energy that helps you sustain performance and delay fatigue.
Two Tailored Formulas for Peak Performance
Original + Recovery: Caffeine-free support for daily training, post-workout muscle repair, and all-round endurance.
Energy+: Infused with caffeine, this version supercharges your focus and endurance during races or intense sessions.
Patented & Scientifically Proven Formula
Using breakthrough oxygen nanotechnology, EI8HT delivers results backed by science—improving stamina, enhancing energy production, and accelerating recovery.
Activates at Peak Heart Rate
Works when your heart rate reaches 80%+ (Zone 4 & 5), helping you unlock performance exactly when you need it most.
Sustained Energy for 80 Minutes
Keep going longer and stronger, whether you're training, racing, or recovering.

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.
Nanotechnology refers to the manipulation of matter at the molecular level, and in our case, it enables the creation of incredibly small, oxygen-filled particles. When you drink our solution, these tiny oxygen molecules are rapidly absorbed into your bloodstream and efficiently transported to the mitochondria in your muscle cells. This targeted delivery ensures that you’re getting oxygen exactly where it’s needed to produce energy, maximizing your performance during intense activity and speeding up your recovery afterward.

When to use EI8HT
EI8HT is engineered for serious endurance — before, during, and after high-effort sessions.
Mix one sachet with 200–500ml of water, shake for 30 seconds, and drink within 15 minutes. It’s activated by intensity — the harder you push, the more it delivers.
For Endurance + Recovery: Use Original + Recovery before, during, or after tough sessions to increase oxygen availability, delay fatigue, and support faster recovery.
For Pre-Race Energy: Use Energy+ 15–30 minutes before training or race day to sharpen focus and maximise output when it matters most.
EI8HT is for those chasing more than just progress — it’s for athletes who want to win, break barriers, and do more than they thought was possible.
