What Is Four Sigmatic Mushroom Coffee?
Four Sigmatic Mushroom Coffee blends regular coffee with powdered mushroom extracts. The emphasis is on adaptogens and functional mushrooms, which are thought to have several possible health advantages. Four Sigmatic sells various coffee mushroom blends, including many mushroom types, each with special qualities. Chaga, Lion's mane, reishi, cordyceps, and turkey tail are among the most popular blends.
Four Sigmatic provides a selection of instant coffee packets, ground coffee blends, and coffee pods made with mushrooms. They offer dietary supplements and other beverages with mushrooms in them. Four Sigmatic strongly emphasizes the quality of its ingredients and sourcing procedures.
Four Sigmatic was founded by a Finnish businessman and novelist named Tero Isokauppila. Tero established Four Sigmatic with the intention of increasing public accessibility to functional mushrooms by putting them into commonplace foods and beverages like coffee. The company was founded in 2012 and moved into the American market in 2015,
Four Sigmatic Mushroom Coffee Review: Pass or Fail?
Four Sigmatic is the first company to combine mushrooms and coffee in a way that preserves the flavor and integrity of the beverage. Some people might find the flavor of some of the blends slightly bitter, but it is certainly not off-putting. The company offers a vast range of products, so you're bound to find a blend that suits your palate while meeting your health needs.
The official website is packed with practical information, helping you choose the best mushroom blend for you. The organic coffees are grouped under three benefit categories - enhanced mental focus, a boost of energy, and long-term positive mood - and each blend's information includes notes on what you can expect regarding taste.
Even though the website states that you can see results in as little as seven days, it usually takes a couple of weeks for the health benefits of lion's mane and other mushroom extracts to take effect. So, you shouldn't expect to see instant results with these blends.
The most popular product in the Four Sigmatic coffee mushroom range is their Think Ground Coffee Bag, which includes Lion's mane and chaga mushrooms. It's got a dark, nutty flavor that I really enjoyed, and it did have a cumulative energy-enhancing effect that was noticeable after a couple of weeks (I took it half an hour before my morning workout).
Four Sigmatic's range is a little pricey. I recommend spending some time on the official website to get your head around the cost-benefit ratio. When you do that, you'll probably agree with me that Four Sigamatic represents a good investment for those who drink coffee and want to supercharge the health benefits of their daily Cuppa Joe.

- Nutrient-dense
- Organic, vegan and gluten-free

Benefits Of Mushroom Coffee
While the science behind mushroom coffee is still being investigated and is not fully established, there is some evidence that it can do the following:
1) Works Synergistically With Caffeine To Avoid Crashes
Some types of medicinal mushrooms, including cordyceps and lion's mane, are thought to have adaptogenic qualities.
Adaptogens are compounds that may aid the body in balancing itself and adjusting to stress. These adaptogens may aid in reducing the stimulating effects of drinking coffee, which can occasionally cause energy dumps and jitters. This might lead to prolonged energy instead of the jarring crashes or jitteriness sometimes associated with normal coffee.
2) May Help With Immune Support
Several types of mushrooms, including maitake and reishi, can boost immunity. That's because they include bioactive compounds that help fight against pathogens. These mushrooms may support stronger immunity when added to coffee with mushrooms.
3) Anti-inflammatory
Some mushrooms, such as chaga and turkey tail, have anti-inflammatory and antioxidant properties. These compounds may aid in reducing bodily inflammation, which is linked to several chronic disorders. By lowering inflammation, drinking mushroom coffee with these mushrooms may improve general health.
4) Might Help With Anxiety
Lion's mane mushroom has been investigated for its potential to improve mood and cognition. According to some preliminary research, Lion's mane may boost cognitive performance and may lessen anxiety and depressive symptoms. It might provide a cognitive boost when paired with caffeine in mushroom coffee while lowering anxiety levels.
5) Other Benefits From Mushrooms
There are a variety of potential health advantages for various types of mushrooms. Lion's mane, for instance, may promote cognitive function and brain health, while chaga might have antioxidant characteristics. Reishi is frequently linked to reduced stress and better sleep. Here are some of the general benefits that come from adding mushrooms to your diet:
- Nutrient Density: Mushrooms are packed with nutrients, including the b vitamins, fiber, and minerals. They're also a non-animal source of Vitamin D, making them great for vegans looking to get more Vitamin D.
- Antioxidants: Mushrooms contain plenty of oxidative stress-reducing antioxidants, including ergothioneine and glutathione(1).
- Immune Booster: Maitake and shitake mushrooms are a rich source of beta-glucans, which may boost the immune system by strengthening our natural defenses (2).
- Anti-Inflammatory: Mushrooms provide a good source of bioactive chemicals that help reduce inflammation, contributing to many ailments.
- Weight Management: Mushrooms are nutrient-dense, low in calories, and high in dietary fiber, making them a great choice for people looking to lose weight.
- Cognitive Benefits: Lion's mane stands out as a mushroom with potential cognitive benefits. It contains compounds that may help produce new brain tissue while also improving focus and memory (3).
- Cancer Prevention: Reishi and turkey tail mushrooms may have anti-cancer properties. This is due to the polysaccharides that they contain, which might be able to slow the spread of cancerous cells (4).
- Skin and Hair Benefits: Mushrooms contain selenium, which promotes healthy hair and skin.

Is mushroom coffee really worth it?
Whether or not mushroom coffee is worth it depends on your taste preferences, how much you value the benefits of mushroom extracts and your budget. Mushroom coffee blends are usually more expensive than standard blends. It is claimed that mushroom coffee can provide cognitive, immune-boosting, and energy-enhancing benefits. Most mushroom blends provide a bitter, earthy taste, which may impact the enjoyment of your coffee experience. We recommend trying a sample pack to see whether mushroom coffee is right for you.
What are the disadvantages of mushroom coffee?
It may take some getting used to the flavor of mushroom coffee for some people. Depending on the type and amount of mushrooms used, it may taste different from ordinary coffee and have an earthy or moderately bitter flavor.
High-quality medicinal mushroom products can be more expensive than regular coffee. Although some studies have suggested that extracts from mushrooms may have health benefits, the body of evidence is still growing and is not as substantial as that for regular coffee or other dietary supplements.
There are fewer regulations governing the mushroom coffee industry than there are for regular coffee, which could lead to variations in the final product's quality and the purity of its ingredients. Buy mushroom coffee exclusively from trustworthy suppliers to ensure the product's quality.

Yes, many Four Sigmatic Coffee products are real coffee. They often start with real coffee, either ground or instant, that has functional mushroom extracts added. The ratios of coffee to mushroom extract can vary depending on the specific product.
