How Four Sigmatic Works

According to the company website, a "Four Sigmatic" food is one that is so rich in nutrients that it is better than average food by four standard deviations. The brand includes many of these 100 foods in all of their Four Sigmatic products.

The founders started the company in Finland after getting the desire to share the benefits of medicinal mushrooms. Now, Four Sigmatic has a free Mushroom Academy, a traveling Mushroom Mobile, and is in over 65 countries. The intriguing concept of their products has led to many famous reviews, including a viral review by Tim Ferriss.

Some of the notable health benefits from drinking coffee with mushrooms include a steady energy boost, antioxidant properties, and reduced inflammation. Some research shows that certain fungi also improve mental and physical performance.

The Mushroom Coffee

There are different types of Four Sigmatic mushroom coffee. The basic ingredients vary by the blend and may include Cordyceps mushroom, Reishi, Lion’s Mane, and Chaga mushrooms. For example, the "Think" mushroom blend contains:

  • Organic Arabica coffee. The dark roast coffee is fair-trade and comes from Honduras.
  • Chaga mushroom extract. Known to support the immune system.
  • Lion’s mane. Supports brain health and function, memory, and focus.

When you browse the flavors online, you can look at each ingredient and its properties. The site encourages you to shop by the benefit you're seeking: Think, Defend, or Chill. The average mushroom coffee contains 30 to 40 mg of caffeine, which is half the amount of a typical cup of coffee.

Mushroom Elixirs

Another beverage option for people who don't want any caffeine at all is to get one of the elixir packets. They have Reishi, Cordyceps Elixir, Chaga, and a Lion’s Mane elixir. You can find information about the differences between each of the medicinal mushrooms before you make a purchase.


You can choose between a regular ground version and an instant coffee version.

Brew the regular grind of mushroom coffee just like coffee, using four tablespoons of coffee to 12 ounces of hot water.

For the instant mushroom coffee mix or the elixirs, combine one packet with eight ounces of hot water.

Of course, you can prepare your mushroom blends to your own taste. Try to make drinks with your favorite plant milk, sweetener, or coconut oil.

What You Can Expect

A Four Sigmatic membership is perfect for any level coffee drinker. You save money if you like the Four Sigmatic products, and you don't waste any money if you don't. When you sign up for a membership, you get:

  • Free shipping in the US
  • Free samples
  • Membership concierge

The mushroom coffee delivery services are flexible, so you can add as much or as little stuff to your box as you want per month.

If you're just starting out, you may want to add a small box of each flavor so that you can get used to mushroom in coffee.

The packaging is bright orange, and it features the exact puns related to mushrooms you would expect.

If you drink one cup of coffee every day, then you're spending about 90 cents per serving on your coffee consumption. This cost is much less than going to your local coffee shop all the time.

Sample Purchases - What Should You Buy?

Since there is a range of Four Sigmatic mushroom coffees, let's break down the properties of each of your options.


The Defend blend is a medium roast made with the medicinal mushrooms Turkey Tail and Chaga. It also has probiotics and prebiotic supplements.

According to scientific evidence, these ingredients support gut health and immunity to disease. If regular coffee usually gives you stomach issues, this is the perfect way to compact that problem.


As we mentioned, the Think blend contains a concentration of Lion’s Mane, Chaga, and coffee. It works to stimulate your mind and central nervous system without causing anxiety and fatigue like too much coffee can. It's a great blend for someone who wants beverages that will increase their productivity or creativity.


Maybe you like the taste of coffee but don't need to be on edge all day. The adaptogen balance blend contains medicinal mushrooms as well as adaptogens ashwagandha, tulsi, and eleuthero. The result is digestion support, increased stamina, and reduced stress.


Four Sigmatic foods ship all over the world. For orders in the United States, you can expect shipping times within three to five days.

If you don't have a membership, your order must be over $100 to qualify for free shipping.

Since you can cancel any time, you might as well sign up for the subscription to take advantage of the lower price.

There are many in-person sellers of Four Sigmatic products.

You can use the store locator on their site to find a location in your area.

However, ordering online helps you find everything that the company offers.

Lastly, if you want to become a reseller instead of a customer, send a message to the brand email address to get a partnership for bulk orders in the works.
