What Cordyceps Does for Athletic Performance (And Why It's in Your Chroma)
Most adaptogens get lumped together under a vague "wellness" umbrella. Cordyceps is different. It has a specific, documented mechanism of action - and a growing body of peer-reviewed research to back it up.
If you've ever wondered why it's in your Chroma, here's the real answer.
What Is Cordyceps?
Cordyceps is a genus of fungi with a long history in traditional Chinese medicine - used for centuries by high-altitude Tibetan herders who noticed their livestock grew stronger after grazing on it. The species most studied for human performance is Cordyceps militaris, which can be sustainably cultivated and standardized for consistent potency.
It's not a stimulant. It doesn't spike your heart rate. It works at the cellular level - specifically inside the mitochondria, where your body converts nutrients into usable energy (ATP).
The Performance Mechanism
Here's what the research actually shows:
1. More ATP, More Power
A 2020 study published in Mycobiology confirmed that Cordyceps militaris promotes cellular energy production by increasing ATP synthesis - the fundamental currency of physical output. When your cells produce ATP more efficiently, you sustain effort longer before fatigue sets in. National Library of Medicine
2. Better Oxygen Utilization
A 2025 review published in Current Nutrition Reports (Springer) summarized human studies on Cordyceps and aerobic performance. Long-term supplementation ranging from 2 to 16 weeks demonstrated improvements in aerobic fitness in active, young participants - consistent with improved oxygen delivery and utilization during exercise. - Ergogenic Aid by Cordyceps
A separate study on Cordyceps militaris and athletes found meaningful improvements in oxygen saturation during performance, suggesting cordyceps supports the body's ability to use oxygen more efficiently at higher intensities - the difference between hitting a wall and pushing through it. - AJBS
3. Reduced Fatigue Markers
Cordycepin — the primary active compound in Cordyceps militaris - has been shown to directly combat exercise-induced fatigue. A 2025 study published in Scientific Reports found that cordycepin administration increased liver and muscle glycogen content (your body's fuel reserves) while simultaneously decreasing serum levels of lactic acid, lactate dehydrogenase, creatine kinase, and blood urea nitrogen - all key markers of exercise-induced fatigue and muscle damage. - nature.com
In plain terms: more fuel stored, less waste product accumulating. That's the difference between fading in the final mile and finishing strong.
4. Anti-Inflammatory & Immune Support
A November 2025 systematic review and meta-analysis published in Frontiers in Nutrition confirmed that fungal supplementation, including cordyceps, positively affects endurance and immune function in adult athletes. This matters because hard training suppresses immune function. Cordyceps helps you recover without losing your edge. frontiersin.org
What This Means During Your Workout
You don't feel cordyceps the way you feel caffeine. There's no 15-minute jolt. Instead, it works in the background - keeping your energy systems running cleaner, your muscles fueled longer, and your recovery faster.
Think of it as the difference between an engine running on dirty fuel versus clean fuel. The output looks the same at first. But over a hard session, the gap widens.
That's why Chroma combines cordyceps with green-tea caffeine and beetroot - the caffeine gets you going, the beetroot improves blood flow and oxygen delivery, and the cordyceps keeps your cellular energy production dialed in underneath all of it.
The Chroma Stack in Context
Every can of Chroma includes cordyceps as part of a performance stack built around one goal: energy that works with your body, not against it.
- Green-tea caffeine + L-theanine → clean, focused energy with no jitters
- Cordyceps → cellular ATP production, reduced fatigue markers, better oxygen use
- Beetroot → nitric oxide production, improved blood flow and power output
- Electrolytes (magnesium, sodium, potassium, chloride) → hydration and muscle function
No sugar. No dyes. No aspartame. Just ingredients that earn their place in the formula.

FAQ
Q: How long does it take for cordyceps to work? Research shows meaningful improvements in aerobic performance with supplementation over 2-16 weeks. In an energy drink you consume regularly, the cumulative effect compounds over time.
Q: Is cordyceps safe? Yes. Cordyceps militaris is well-tolerated in human clinical studies with no significant adverse effects reported at standard supplementation doses. It is not a stimulant and does not raise heart rate or blood pressure.
Q: Why is cordyceps in an energy drink specifically? Because energy drinks aren't just about caffeine anymore. Performance athletes need sustained output - not just a spike. Cordyceps addresses the cellular side of energy that caffeine alone can't touch.
Q: Does Chroma use Cordyceps militaris or Cordyceps sinensis? Chroma uses Cordyceps militaris - the species with the most robust body of human performance research and the one that can be sustainably cultivated for consistent potency.
