If you're looking for a pre-workout without the jitters, cordyceps may be worth a look. This functional mushroom has been used for centuries in traditional Chinese and Tibetan practice to support energy, stamina and endurance, and today it's a favorite among runners, lifters and weekend athletes.*
Here's what cordyceps is, what the research suggests, and how to fit cordyceps gummies into your training.
What Is Cordyceps?
Cordyceps is a group of fungi. Two types are used most often in supplements:
- Cordyceps sinensis (now called Ophiocordyceps sinensis) grows wild at high altitudes on the Tibetan Plateau. Wild sinensis is rare and very expensive, so most supplements labeled "sinensis" use a cultivated strain.
- Cordyceps militaris is cultivated, more widely available, and a natural source of cordycepin, one of the compounds researchers study most.
Our Cordyceps Gummies are made with USDA Organic Cordyceps militaris fruiting-body extract.
How Cordyceps May Support Your Workouts
Research on cordyceps and exercise is still developing, and studies have used different species, doses and people, with mixed results. Here's how athletes most often use it:
- Energy and stamina: cordyceps is traditionally used to support natural energy and help you go the distance.*
- Endurance: some small studies have looked at whether cordyceps supports oxygen use during exercise.*
- Occasional fatigue: many people take cordyceps to help push through low-energy days.*
- Occasional stress: cordyceps is often described as an adaptogen, an herb or mushroom traditionally used to help the body adapt to everyday stress.*
Cordyceps isn't a stimulant like caffeine. People tend to use it daily as part of a routine, rather than expecting an instant jolt.
Cordyceps vs. Traditional Pre-Workouts
Many pre-workout powders rely on high doses of caffeine and other stimulants. That can mean jitters, an energy crash, or trouble sleeping if you train in the evening. Cordyceps gummies are a stimulant-free option. Some people take them on their own; others pair them with a cup of coffee.
When to Take Cordyceps Gummies
- Before a workout: many people take cordyceps about 30–60 minutes before training.
- In the afternoon: for a mid-day lift without more caffeine.*
- Every day: consistency matters more than timing, so take it at the same time each day.
Always follow the suggested use on the label.
What to Look For in a Cordyceps Gummy
- Fruiting body, not mycelium on grain. Grain-grown mycelium can dilute the mushroom compounds with leftover rice or oats.
- A clear amount per serving. Look for milligrams of cordyceps extract per serving, not just per bottle.
- The species named on the label.
- Third-party or batch testing for purity and potency.
- Clean ingredients: natural flavors and colors, and no gelatin if you're vegan.
