In today’s fast-paced world, many of us are turning back to nature in search of balance, energy, and long-term wellness. Natural remedies like medicinal mushrooms are rising in popularity, but they’ve actually been used in traditional medicine for centuries.

Among the rising stars? Cordyceps, a curious, powerful fungus with a fascinating origin story and some promising benefits for both body and mind. At Naturecan, we’re passionate about helping people understand the science behind wellness trends. That’s why we’ve put together this in-depth guide to Cordyceps. What it is, how it works, what the research says, and how to use it safely.

    What is a Cordyceps Mushroom?

    Cordyceps has an interesting nickname, as it is also known as the “zombie mushroom”. But there’s a reason for the name. In the wild, Cordyceps grow by infecting insects, eventually taking over their bodies and sprouting from them.

    Thankfully, the Cordyceps used in supplements today are cultivated in controlled environments so instead you get the potential benefits without the bug-related origins. This mushroom has been used in Traditional Chinese Medicine for centuries to potentially help support energy, endurance, and vitality, and modern science is now catching up.

    Cordyceps Lifecycle

    To understand just how unique Cordyceps is, it is helpful to examine its lifecycle. Here’s a quick overview:

    StageWhat Happens
    Spore Landing Cordyceps spores land on an insect (usually a caterpillar).
    Infection The spores grow into the insect, gradually taking over its body.
    Mushroom Growth A fruiting body (the mushroom part) grows out of the insect.
    Spore Release Spores are released into the air, starting the cycle again.

    Of course, the Cordyceps found in supplements and powders, like the ones in our Mushroom Gummies are grown without insects, usually on rice or soy. So, they're completely suitable for vegans.

    Types of Cordyceps

    There are more than 700 different species of Cordyceps, but two in particular stand out for their health benefits:

    • Cordyceps sinensis – The one that’s been used in ancient medicine for generations. It's wild, rare, and costly.
    • Cordyceps militaris – The modern, cultivated version is most commonly found in Cordyceps supplements today. It’s rich in beneficial compounds like cordycepin and can be grown sustainably.

    Both have similar benefits, but most of the supplements you’ll find on the market use Cordyceps militaris because it’s more accessible and just as effective.

    Potential Cordyceps Benefits

    So, what can Cordyceps actually do for you? While research is still underway, early studies and traditional use suggest several potential benefits:

    1. Boosts Energy and Stamina

    Cordyceps is often associated with increased energy levels, which is why it’s popular with athletes and gym-goers. It may help your body use oxygen more efficiently and produce more ATP — the molecule responsible for cellular energy. [1]

    2. Supports Physical Performance

    In one study, older adults who took Cordyceps showed improved exercise performance and oxygen uptake.

    It’s no surprise it’s made its way into many pre-workout blends. [2]

    3. Strengthens the Immune System

    Some research suggests that Cordyceps can help stimulate key immune cells, such as natural killer cells and macrophages.

    A stronger immune response means your body is better equipped to handle stress and illness. [3]

    4. Antioxidant Protection

    Cordyceps are rich in antioxidants, which help fight off free radicals, unstable molecules that can damage cells and contribute to ageing.

    5. May Improve Respiratory Health

    Cordyceps has been used in traditional medicine for centuries to help with fatigue and breathing issues, and modern research is starting to catch up.

    One of its standout benefits may be its ability to support lung function and improve how the body uses oxygen. This is thanks to compounds like cordycepin and adenosine, which may help boost oxygen uptake and make breathing feel easier, especially during physical activity.

    In fact, some studies have shown improved exercise performance and better breathing in people taking Cordyceps. [4]

    Cordyceps Benefits for Males

    For men, Cordyceps may offer some specific advantages:

    • Improves Physical Energy – Whether you’re into weight training or just tackling a long workday, Cordyceps may help support your energy levels.

    Cordyceps Benefits for Females

    Cordyceps may also provide unique benefits for women:

    • Helps Manage Fatigue – It may support better energy levels throughout the day, especially during busy periods or hormonal changes.
    • Immune System Support – A boost to the immune system can help you bounce back quicker during times of stress or illness.
    • Natural Hormonal Balance – While more research is needed, Cordyceps may support hormonal balance during menstruation or menopause.
