Take 2 capsules of VO3 with water about 20–30 minutes before training or competition. Because VO3 is stimulant-free, you can also take it later in the day or evening without worrying about sleep disruption. For best results, use consistently as part of your training routine to support endurance, oxygen efficiency, and overall performance.
VO3 is intended for healthy adults 18 years and older. Do not use if you are pregnant, nursing, or have a known medical condition without consulting your physician first. Always check with a healthcare professional before beginning any new supplement. Do not use if the safety seal is broken or missing. Store in a cool, dry place and keep out of reach of children.

Benefits
Boosts VO₂ Levels
VO3 is built to increase oxygen utilization, helping athletes sustain high-intensity efforts longer.
Stimulant-Free
Unlike typical pre-workouts, VO3 contains no caffeine or harsh stimulants. That means clean energy, sharper focus, and zero jitters.
Scientifically Synergistic Formula
With just three proven ingredients — Cordyceps, ATP, and Rhodiola rosea — VO3 delivers performance benefits without fillers or fluff.
Faster Recovery
By supporting oxygen delivery and ATP production, VO3 helps reduce mid-session fatigue so you can recover quicker between rounds, drills, or sets.
Adaptogen Support
Rhodiola rosea helps the body adapt to both physical and mental stress. That means steadier energy and improved resilience under pressure.
Clean, and Athlete-Friendly
VO3 is gluten-free, and free of artificial dyes, flavors, or fillers. Just pure and effective ingredients.
Proof By Our Customers
Jamie
I train BJJ at night and used to avoid pre-workouts because they ruined my sleep. VO3 gives me clean energy and endurance without the crash or caffeine jitters. I can roll hard and still fall asleep easily afterwards.
Lucas
I’ve been taking VO3 before conditioning workouts, and my gas tank feels completely different. I’m able to push longer without that usual wall. The fact that it’s stimulant-free and only 3 ingredients makes me trust it more than other products I’ve tried.
Mark
I love that VO3 doesn’t have dyes, fillers, or artificial junk. Just the essentials. I use it before lifting and during MMA training, and I feel stronger and more consistent through sessions. Definitely staying in my bag from now on.
Kathy
I started using VO3 for long runs and cycling sessions, and the difference is clear. My breathing feels smoother, and I don’t hit fatigue as quickly. It’s refreshing to have a supplement that’s clean, vegan, and actually delivers without the stimulant buzz.
