Altitude BoostYour journey on VO2 Boost
Real results build over time. Here's how your body responds as the formula goes to work.
Day 1
Your first dose
You take your first serving and the journey begins. No magic overnight — but the formula starts building in your system from day one.
First 14 days
The formula activates
Beta-alanine and adaptogens begin building in your system. Many athletes notice steadier energy and a little less fade late in sessions.
Around 1 month
Endurance gains show up
Oxygen efficiency improves. This is where most athletes report holding pace longer and recovering faster between hard efforts.
3 months +
Peak performance
Full benefits compound with consistent training. A higher VO2 max ceiling, stronger finishes, and new personal bests within reach.
The endurance ceiling
Your legs still have fuel. Your oxygen runs out first.
Every endurance athlete hits the same wall — not because you're unfit, but because your body can't pull in and use oxygen fast enough to keep pace. That ceiling has a name: your VO2 max.
VO2 Boost raises that ceiling. Six clinically-studied ingredients work together to increase oxygen uptake, delay fatigue, and let you hold your pace when it counts.
No proprietary blends · nothing hidden
We show you exactly what's in every capsule and the research behind it — because real results come from real science, not marketing.
Rhodiola Rosea
Reduces fatigue and sharpens focus under physical stress.
An adaptogen that helps regulate cortisol and supports oxygen delivery during high-stress training.
Cordyceps
Boosts energy production and oxygen utilization.
A performance mushroom shown to support ATP production and improve how efficiently muscles use oxygen.
Quercetin
Increases oxygen uptake and supports heart health.
A flavonoid that promotes mitochondrial biogenesis and reduces exercise-induced inflammation.
Catechins (Green Tea)
Enhances fat oxidation and sustained energy.
Powerful antioxidants that support metabolic efficiency and protect cells from oxidative stress.
Beta-Alanine
Buffers lactic acid to delay muscle burn.
Raises muscle carnosine levels, helping you sustain high-intensity efforts before fatigue sets in.
Echinacea
Supports immunity for consistent training.
Helps maintain immune resilience so illness doesn't interrupt your training momentum.
Trusted at the highest level
World champions, Olympians, and elite competitors who train with VO2 Boost.
World champion
Jonah Koech Kipruto is a Kenyan-born middle-distance runner who represents the United States in international competitions.
In the 1500, the race doesn't start until the bell. Everyone's fit at that point — what separates you is who can still access oxygen when the lactic acid is screaming. VO2 Boost is the reason I can kick at 300 out instead of just holding on.
World champion
500+ career victories
World champion ultra-endurance cyclist who conquered the 3,000-mile Race Across America at age 60. Over 500 career victories spanning decades of competitive racing.
At 60, everyone tells you the ceiling is coming down. VO2 Boost helped me prove them wrong. I rode 3,000 miles across America and my oxygen efficiency held deep into stages where guys half my age were fading. Age is a number — your VO2 max doesn't have to agree with it.
Olympian
2x Gold, African Games
Tunisian Olympian and two-time African Games gold medalist. One of the most decorated rowers in African championship history, competing at the highest international level.
Rowing is the most oxygen-demanding sport on earth — every stroke pulls from your aerobic system at maximum capacity for seven straight minutes. VO2 Boost gives me the oxygen efficiency to keep my stroke rate high in the third 500 when my competitors start to fall apart.

Really good product
Altitude Boost has helped me adapt faster and train stronger at elevation. My oxygen efficiency, stamina, and recovery all feel improved. For athletes who train at high altitude or want the same benefits, this supplement really delivers. BRL Nutrition maintains top quality in every product—and this one is no exception. Highly recommended!
Je bien reçu mon commande il est arrivé en temps, merci beaucoup pour votre confiance.
I've tried a few other altitude boosters and none are as effective as this one. I use it daily for cardiovascular enhancement.
Lo mejor . Yo vivo en una cuidad que no tiene nada de altitud. Y me siento con el producto súper bien . Como si fuera a entrenar alas montañas
