Four Sigmatic Think Instant Coffee is specifically formulated as a substitute for your regular morning coffee. It combines the advantages of consuming coffee and functional mushrooms while containing only half the caffeine. Additionally, the product is organic and can be conveniently prepared as a hot or cold brew.

Is it worthwhile to replace your morning coffee with a healthier alternative from Four Sigmatic, or is the traditional cup still the best start to the day?


  • Both of the Four Sigmatic mushrooms are known to be beneficial
  • Totally organic, gluten-free, paleo, and vegan-friendly
  • It tastes good warm or cold


  • It is not as effective as regular coffee or a top mushroom coffee.
  • Value for money could be better

Quick Verdict

On the surface, Four Sigmatic Think Organic Instant Coffee appears to be an excellent mushroom coffee. The taste is good and the components are all organic, ethicaly sourced and proven effective.

But they are also somewhat underdosed which is I prefer Nootrum Coffee Fusion. It's the greatest mushroom coffee I've had. It reaps the benefits of drinking coffee and eating adaptogenic mushrooms while tasting wonderful hot or iced, with no caffeine crashes.

Four Sigmatic derives its name from the statistical concept of "four sigma," which signifies the top 100 most nutrient-dense meals in existence.

Four Sigmatic Mushroom Coffee Ingredients

Four Sigmatic Mushroom Coffee

Four Sigmatic produces various products, but I'll focus on their Think Organic Instant Coffee. It is their most popular product, combining ground coffee with Lion's Mane, Chaga mushrooms, and Rhodiola extract, most of which have been grown on the founder's family farm.

Organic Instant Coffee Powder

Any cup of coffee contains some coffee bean extract, which is recognized for its high caffeine concentration and distinct flavor.

Coffee beans can increase your energy and improve your focus, which is why drinking coffee in the morning is so popular. Coffee has numerous benefits.

This includes protecting the brain, liver, and heart, decreasing blood sugar and cholesterol levels, and avoiding specific health problems [1].

An average cup of coffee contains approximately 5 g of ground coffee beans.

One serving of Four Sigmatic Think measures 2.5 g and contains three substances other than coffee beans. Thus, it will most likely deliver half the benefits of regular coffee.

Log Grown Organic Lion’s Mane Mushroom Extract

The Lion's mane mushroom is a common fungus with various culinary and medicinal uses.

It has a distinct flavor and texture, provides numerous health benefits, and is the most effective medicinal mushroom species.

Lion's mane supplements can improve brain health and function, cognitive performance, brain cell growth, blood supply to brain cells, attention, memory, and concentration, combat brain fog, mental decline, and other mental health difficulties.

The Lion's Mane mushroom also has various physical benefits. These include strengthening the immune and neurological systems, increasing aerobic capacity, athletic endurance, oxygen usage, energy levels, ATP synthesis, and lowering inflammation.

The issue is that Lion's mane mushrooms only exhibit these effects if ingested at a dose of at least 1,000 mg per day [2].

The lack of indicated dosages makes it hard to determine whether Four Sigmatic Think includes this amount of organic Lion's Mane mushroom extract.

However, the fact that each portion weighs only 2.5 grams and is the second listed component makes it extremely unlikely. When you analyze how it tastes, it appears that the product is not made up of equal parts coffee and Lion's mane.

Wildcrafted Organic Chaga Mushroom Extract

The Chaga mushroom is an edible macroscopic fungus that grows mainly on birch trees

It contains various therapeutic chemicals, including melanin, polyphenols, triterpenoids, and polysaccharides, and is rapidly becoming one of the most popular medicinal mushroom species.

These nutrients provide both mental and physical health benefits, such as enhancing your digestive and immune systems, improving attention and energy levels, lowering blood sugar and cholesterol levels, and preventing or curing cell mutation, exhaustion, and certain chronic illnesses and somatic disorders [3][4].

Unfortunately, studies have indicated that at least 500 mg of chaga extract must be ingested daily to achieve these results.

While the lack of dosages makes it impossible to say whether there is enough to achieve these consequences, it seems unlikely.

Worse, even if enough is present, this means the Lion's Mane extract, which is the more potent of the two mushrooms, is too small in quantity.

Organic Rhodiola Extract

Rhodiola extract is derived from the roots of the Rhodiola rosea plant, which is an adaptogen very similar to mushrooms.

It contains over 140 distinct micronutrients and has been utilized in herbal remedies for millennia because of its health benefits.

It can aid in preventing or treating stress, anxiety, depression, mental tiredness, and inflammation, as well as improve mental energy levels, brain health, focus, cognitive function, metabolic processes, concentration, and mood, and combat specific diseases.

The problem is that it will only do any of these things if you consume at least 50 mg per day [5]. While it is very plausible that Four Sigmatic Think contains this amount, the lack of indicated doses makes it impossible to say with certainty. Its position near the bottom of the ingredients list renders this unlikely.

Infused with beneficial mushrooms such as Lion's Mane and Chaga, it gives a smoother caffeine experience without the crash, making it ideal for people looking to reduce caffeine consumption without giving up their coffee ritual.

Health-Conscious Individuals Seeking Mushroom Benefits Without the Taste

This coffee mix is a dream come true for health-conscious individuals who dislike mushrooms' flavor. The deep, dark coffee flavor conceals the taste of mushrooms, allowing you to experience their numerous advantages, such as increased immunity and cognitive function, without sacrificing taste.

Coffee Lovers Who Want a Smooth, Crash-Free Brew

Four Sigmatic Mushroom Coffee provides an excellent, full-bodied coffee experience without bitterness. Because of the addition of nutrient-dense mushrooms, each cup promotes prolonged energy, attention, and productivity without the traditional coffee crash.

Individuals Seeking Enhanced Focus and Creativity

Lion's Mane mushroom, recognized for its nootropic characteristics, is an essential ingredient in Four Sigmatic Mushroom Coffee.

My Experience With Four Sigmatic Mushroom Coffee

I made my first cup of Four Sigmatic Think hot in a French press. It produces dark mushroom coffee with a distinct aroma and a good flavor, albeit it may be an acquired smell and taste.

I then tried several methods of preparing it, such as brewing it with cold water or pouring it over ice, and the results were quite consistent. However, using cold water made the coarse grind much more apparent.

The wide choice of ways to make Four Sigmatic Think and the pleasant taste make it a great morning beverage option, and some people will prefer to replace their regular coffee with this one.

For me, I am not sure I want to. The Fours Sigmatic Think mushroom coffee provides noticeable benefits but is somewhat lackluster compared to a top mushroom coffee or a classic cup of espresso.

The mushroom mix is low compared to optimal dosages, but it's still beneficial. The lower caffeine dosages may be perfect for people wary of jitters and energy crashes.

So, while I prefer more potent drinks and effects, the Four Sigmatic Think will certainly cater to people falling into the groups I listed in the previous segment of this review.

It's why it's ranked in my list of best mushroom coffees.

Four Sigmatic Customer Reviews

Looking at the customer reviews for Four Sigmatic Think, things appear to be extremely positive. The product now has a 4.3 out of 5-star rating on Amazon out of an impressive 17k reviews. 

When checking the good reviews, the most popular remarks are its low pricing and "delicious" taste whether you drink it with or without milk or sugar, hot or cold.

However, there are also negative reviews. These felt more telling than the positive ones, as they centered on how the mushroom coffee affected them. Many claimed it accomplished nothing and was less effective than a cup of coffee.

Some consumers also claimed that the flavor was off or too weak. Others argued that its price and efficacy, compared to conventional coffee, did not provide superior value for money.

Four Sigmatic Alternatives

Nootrum Coffee Fusion

Nootrum Coffee Fusion appears very similar to Four Sigmatic in that it blends pulverized coffee beans with Lion's mane and Chaga mushrooms.

Aside from the fact that Rhodiola extract is not included, there is one significant difference: the mushrooms are utilized in the proper quantities.

As a result, Nootrum Coffee Fusion can provide the most optimal results. This means that it aids in managing stress, promotes prolonged energy and focus, makes concentration easier, and enhances productivity as well as the health and functions of your brain and body.

This is all while drinking great coffee, which makes each cup delightful. You won't need to add sugar, honey, coconut milk, or other sweeteners or flavorings.

Elm & Rye Mushroom Complex Coffee Creamer

Elm & Rye Mushroom Complex differs from the other mushroom coffee items we tested; it is not a real mushroom coffee.

Instead, it is a mushroom supplement with high-quality components, including the two mushrooms we previously discussed plus maitake and cordyceps mushrooms. It is unique in that it comes in three different varieties, one of which is a coffee creamer.

This makes it a perfect choice for those who want to continue drinking their usual coffee while still reaping the benefits of a mushroom blend.

You have more control over how much caffeine they consume, as well as the flavor and texture of each cup.

Nootrum Powder

Nootrum Powder is another product that is not precisely mushroom coffee. However, it is the most potent powdered mushroom supplement available today.

Cordyceps, reishi, royal sun agaricus, shiitake, maitake, turkey tail mushrooms, inulin, green tea leaf extract, fermented ginger root, acerola cherry extract, and cassava maltodextrin are all organic ingredients.

By incorporating this into your regular coffee, you will have more control over the flavor of each mug while also reaping the advantages of medicinal mushrooms. You'll also be able to limit your coffee intake and avoid crashes.


Four Sigmatic says that its Think Organic Instant Coffee provides all of the benefits of regular coffee and medicinal mushrooms without the crashes that caffeine can cause.

In my experience, this is partially true. The product does deliver caffeine and mushroom benefits, but a bit too lightly for my taste. Still, with nearly 20,000 Amazon reviews and a high overall score, it seems many people find the combination highly enjoyable.

I prefer my coffee and supplements stronger, which is why Nootrum Coffee Fusion is my favorite mushroom coffee. It uses a very similar recipe but with properly dosed components, providing all the benefits of mushrooms while being super delicious.
