Let’s Dig In: Reviewing Four Sigmatic Mushroom Coffee

I adore everything about coffee: the daily ritual, the taste, the aromatics, and admittedly, the caffeine high. Coffee is so much a part of my day-to-day that I recently carved out a small spot in my home for a coffee bar. This coveted corner is where I store my espresso machine and grinder, various French presses, pour-overs, coffee mugs, and of course, a stockpile of various beans to try out. But one thing I always have on hand is mushroom coffee.

Last year, a sports nutritionist I follow was promoting Four Sigmatic Mushroom Coffee on her page, touting a list of health benefits and I became intrigued. After reading up on the brand, I also noticed that some of their products contain just half the amount of caffeine as a regular cup of coffee and I swiftly purchased a bag to try out. Flash forward a year later, and the novelty of the Four Sigmatic Mushroom coffee has yet to wear off.

So, What’s in Four Sigmatic Mushroom Coffee?

Organic Coffee: Fair-trade and sustainably grown coffee
Organic Lion’s Mane Extract: (250 mg per serving) Lion’s Mane, also known as hou tou gu or yamabushitake, are large, white, shaggy mushrooms that resemble a lion’s mane as they grow. In China, India, Japan and Korea, Lion’s Mane is often used as an over-the-counter supplement. It is thought to be beneficial for the brain, heart and gut health and can be used as a medicinal supplement to treat anxiety and depression, speed in the recovery of the nervous system, as well as boost the immune system.
Organic Chaga Extract: (250 mg per serving) A black fungus, also known as Inonotus obliquus, that grows on birch trees and is native to cooler regions of North America, Asia and Europe. Known for its medicinal properties, it’s believed that chaga may have antioxidant and anti-inflammatory properties making it an alternative remedy for ailments such as arthritis and high blood pressure.
Nutritional Facts: Serving Size: 4 Tbsp (21g), Calories: 5, Fat: 0g, Sodium: 0mg, Carbohydrates: 1g, Protein: 0g


At first sip, I was pleasantly surprised by how much it tastes like regular ol’ coffee – there is no strange aftertaste or earthy flavours like I was expecting. A cup of Joe without the caffeine crash and the added bonus of having lion’s mane and chaga extract makes this cup of coffee truly special.


At $20 (USD) a bag, the price point is a bit on the higher end but comparable to a lot of speciality coffee beans out there. But, if you do like it, Four Sigmatic offers a subscription service on their site, allowing you to save money, get free shipping and save 20% off subscription based products – which just makes sense.

Will I Buy Again?

Yes, I always have a bag on hand. I’m super curious to try out their Instant Mushroom Coffee with Lion’s Mane since it has lower levels of caffeine (just half the caffeine as a regular cup) and would be perfect on the days when you really want coffee but it’s pretty late in the day. What about you? Have you tried Four Sigmatic Mushroom Coffee? What did you think? Tell me all about it below.

Stay well,
