10 Best Reishi Mushroom Supplements (2022) Reviewed and Compared

Never miss a glorious update - click here!

If you want to add more years to your life (and more life to your years), taking mushrooms could help. No, we don’t mean those kinds of ‘shrooms (although no judgment if you like those).

We’re talking about a medicinal mushroom blowing up in natural health circles, called Reishi.

They won’t have you tripping out, but reishi mushrooms have a magic of their own.

What are Reishi Mushrooms?

Reishi mushrooms – known by the scientific name Ganoderma lucidum – are edible fungi native to east Asia.

Reishi falls into the same category as Lion’s mane (we’ve written about this in detail), Cordyceps (again, we’ve covered it), and Turkey tail (yes, I suppose we’re mushroom experts.)

Known as Ling Zhi in Chinese, they’ve been a staple of traditional Chinese medicine (TCM) for thousands of years.

Traditional healers believe these red-capped mushrooms help the body cope with stress and maintain a state of balance. That’s how they got the nickname “the king of mushrooms.”

What Are the Health Benefits of Reishi Mushrooms?

Researchers have found hundreds of bioactive compounds in reishi mushrooms.

One of these is beta-glucan, a soluble fiber in the mushroom’s cell wall with immune-modulating properties.

Reishi also contains antioxidant, anti-inflammatory, and anti-cancer compounds like triterpenes and polysaccharides.

I’m going to level with you. Reishi probably isn’t the panacea for focus, stress resilience, and mood that mushroom companies swear it is. 

That said, the studies are encouraging, and there are companies doing mushrooms right.

What does science say about reishi mushrooms?

The lion’s share of the research around reishi mushrooms focuses on supporting immunity. Particularly for people with cancer.

A polysaccharide extract from reishi may boost the activity of white blood cells like lymphocytes and natural killer (NK) cells in cancer patients. These cells make up the immune system’s surveillance team. They travel around looking for suspicious cells to munch (think of them as packmen).

Unfortunately, immune cells become compromised due to aging, stress, and other lifestyle factors. That’s why reishi extract is getting so much attention. It may even shrink precancerous tumors and kill certain cancer cells!

A lot of the research has been in animal and cell studies, so this isn’t an endorsement to use it as a first-line therapy. But it’s worth a look as an adjunct to conventional treatments.

Even if you aren’t sick, reish may support your immune system when you’re burning the candle at both ends.

Over the last couple of decades, medicinal mushroom farming has, well, mushroomed. But it’s crucial to pick manufacturers who value quality and know what they’re doing.

Here are our top picks for the best reishi mushroom supplements on the market (and you better believe every product is tested for purity and potency).

Real Mushrooms have been in the ‘shroom biz for more than 40 years. They know their stuff.

One of their Reishi Mushroom Capsules provides 500 mg of pure reishi extract in an 8:1 ratio.

You can tell it’s the real deal by the concentration of beta-glucans and triterpenes in each serving – more than 15% and 4%, respectively. And they are third-party tested to confirm this.

Real Mushrooms only uses certified organic mushrooms cultivated in China. You may raise your eyebrows at the words “made in China.” But Real Mushrooms believe the purest mushrooms are cultivated in their native mountainous habitat, far from industrial areas.

Real Mushrooms is probably our favorite medicinal mushroom brand (and we’ve seen a lot). It’s hard to beat this quality at this price.

This product is for you if you prefer herbal tinctures. 1 ml of Nature’s Answer Reishi Tincture provides 1000 mg of pure reishi extract.

I like squirting a few drops in a glass of water. But if you don’t like the bitter taste, add it to tea, coffee, juice, a protein shake, or a smoothie.

It’s alcohol-free, making it ideal for tea-totalers (or anyone with an allergy). The Bio-Chelation® process eliminates any alcohol from the tincture without impacting the potency.

Fresh Cap has developed a herbal elixir that helps you relax. Each sachet contains a blend of reishi extract, Chaga extract, magnesium chamomile, peppermint, l-theanine, passionflower, and monk fruit. It’s also non-GMO, vegan, gluten-free, and paleo.

I think it’s pretty tasty – I’d describe the flavor as rich with a dash of peppermint.

This is a pricier option. However, they’ll give you 20% off if you subscribe.

How We Ranked

We think these are the best reishi products available. But we want you to make the best decision for your lifestyle.

Here’s what we took into consideration when making our list.

Strict Testing Standards

The supplement industry isn’t FDA-regulated. You need to ensure reishi supplements contain enough active ingredients (like beta-glucans) and are grown responsibly.

Luckily, that’s what we do at RFS.

We’ve picked products made according to Good Manufacturing Practices (GMP). Plus, we prioritize companies who submit their products for third-party testing and use FDA-registered production facilities.

Ingredient Source and Quality

Unfortunately, unscrupulous manufacturers take shortcuts to save money. Many brands only use the mushroom’s root system (called the mycelium) because it’s cheap and fast to grow. But it’s less potent than the fruiting bodies that grow above ground.

We’ve listed reishi supplements containing the reishi fruiting body (where most of the bioactive compounds are found). Some supplements also contain mycelium, but it’s never the sole ingredient.

Organically grown mushrooms also get a boost, as do products free from fillers.

Convenience

We’ve included supplements, powders, and tinctures so you can pick something that suits your lifestyle.

Dose

The products we chose make it easy to consume an effective-yet-safe dose of reishi extract (while allowing you to adjust it as needed).

Value

We believe you shouldn’t need to bankrupt yourself to support your health.

While medicinal mushrooms can be pricey due to the cultivation and extraction processes, we looked for high-quality products that are also affordable.

FAQ

Can Reishi Mushrooms Improve Energy?

One of the claims about medicinal mushrooms is that they give you boundless energy. Sadly, there’s no evidence to confirm this for reishi mushrooms.

But it seems to help people with cancer and fibromyalgia feel healthier and physically fitter.

Does Reishi Improve Anxiety and Depression?

Reishi extract may increase life satisfaction and reduce depression in people with fibromyalgia. It may also improve anxiety and depression in breast cancer patients.

But we don’t know if it has the same effect in other populations.

Can Reishi Mushrooms Improve Metabolic Syndrome?

Reishi mushroom extract may play a role in managing metabolic syndrome (characterized by obesity, poor blood sugar management, and high cholesterol).

Compounds in reishi extract appear to reduce some of these markers, namely insulin resistance, high cholesterol, and high triglycerides.

However, there is conflicting research on the topic.

Are Reishi Mushrooms Neuro-Protective?

Boosting brain health and focus is another anecdotal benefit of reishi.

Polysaccharides from reishi support neurogenesis in mice. This is the creation of new, healthy neurons in the brain – something we all need to stay mentally flexible as we age.

That said, there aren’t human studies to confirm this. Until we know more, you might be better off using lion’s mane.

Are There Any Side Effects of Taking Reishi Mushrooms?

Reishi extract is safe and well tolerated by most people in doses up to 6 grams daily.

In some people, it may cause mild digestive symptoms. And its immune-enhancing properties mean it’s not advised for people on immune-suppressants.

Research on reishi mushrooms is still emerging. Speak to your doctor before supplementing if you have a chronic health condition.
