Reishi vs Cordyceps: Which Functional Mushroom Is Right for You?

Two of the most talked-about mushrooms in the supplement world right now are Reishi and Cordyceps.

One is known for calm, sleep and stress relief. The other is linked to energy, stamina and performance. But which one should you be taking? And can you use them together?

If you’re weighing up Reishi vs Cordyceps, this blog breaks it down clearly — no fluff, no hype, just what you need to know.

What is Reishi?

Reishi mushroom (Ganoderma lucidum) has been used in traditional medicine for centuries. Often called the “mushroom of immortality,” it’s best known for supporting sleep, stress relief, immune health and emotional balance.

Reishi is a calming adaptogen. It helps regulate your body’s stress response and nervous system, making it one of the most popular options for people who feel overwhelmed, wired or burned out.

Reishi powder is ideal for those who want to:

• Wind down and sleep better

• Reduce stress and anxiety

• Support long-term immune health

• Balance mood and nervous system function

What is Cordyceps?

Cordyceps mushroom (Cordyceps militaris) is the opposite end of the spectrum. It’s all about energy, endurance, oxygen use and physical recovery.

Instead of stimulating your nervous system like caffeine, Cordyceps helps your body produce more ATP, the cellular energy molecule. That means you get a clean, steady energy boost without the crash.

Cordyceps is ideal for those who want to:

• Train harder and recover faster

• Boost physical energy and stamina

• Improve oxygen uptake and performance

• Stay alert without caffeine

Key differences between Reishi and Cordyceps

Reishi powder supports rest, recovery and resilience. It’s grounding, calming and ideal for winding down. Cordyceps powder supports energy, movement and performance. It’s uplifting, energising and great before physical activity.

They’re both adaptogens, but they act on different systems:

• Reishi works on the nervous system and immune system

• Cordyceps works on the respiratory system and cellular energy production

This means you can use them together, depending on your goals.

Can you take Reishi and Cordyceps together?

Yes. In fact, many people use Reishi mushroom powder in the evening and Cordyceps powder in the morning to support full-day balance.

It looks like this:

• Morning: Cordyceps mushroom supplement for energy and focus

• Evening: Reishi powder to relax, de-stress and sleep well

This creates a natural rhythm - energise during the day, wind down at night.
