Four Sigmatic is a US based company that specializes in making special coffees, elixirs, and skincare products. 

Many of these products contain mushroom extracts, which are powerful superfoods, with organic coffee to create products that easily fit into their customer’s daily lifestyles while also giving them the benefits and nutrition they crave.  

Four Sigmatic Intro

What is Four Sigmatic?

Four Sigmatic has a very different view on health than most companies. The company founders brainstormed with each other, focusing on what they wanted to put in their own bodies. 

Instead of using many different supplements and pills and expensive health drinks, they realized they simply wanted actual foods that made them healthier. 

There’s a lot of talk about superfoods in the health community, but the founders of Four Sigmatic decided that the most powerful superfood out there was mushrooms. 

What Products Do They Make?

Though most popular for their Mushroom Coffee Mix, which blends 100% Arabica coffee with Lion’s Mane mushroom extract and Chaga mushroom extract, Four Sigmatic offers a wide variety of foods, drinks, and skincare that contain the best superfood ingredients out there.

Why Use Mushrooms?

Most people over the years have associated mushrooms with food or psychedelic drugs, but many are not aware of the wonderful health benefits they can provide. 

In fact, one thing most don’t know is that mushrooms play a huge role in the production of penicillin, the most popular antibiotic available to man.

Some of the main benefits you’ll find among most mushrooms:

  • They are rich in selenium, which carries several benefits including anticancer, antioxidant, and anti-inflammatory properties.
  • They help to lower cholesterol.
  • They can prevent diabetes.
  • The can improve bone health, lowering the risk for diseases like bone cancer or osteoporosis.
  • Provide vitamin D, which can help the body absorb and metabolize nutrients.
  • They can boost the immune system.
  • They lower blood pressure by providing high levels of potassium.
  • Are an excellent source of copper which can increase iron absorption.
  • Increase protein intake.
  • They can also aid in weight loss.

What Mushrooms does Four Sigmatic Use?

As their name suggests, Four Sigmatic uses four mushrooms in their many of their products. Those mushrooms are Lion’s Mane, Chaga, Cordyceps, and Reishi

Each individual mushroom brings it’s own set of benefits, and with many of the products Four Sigmatic creates, blending them enhances those benefits.

Lion’s Mane: The Chinese have been using this mushroom medicinally for centuries, especially to aid with ailments of the brain.

It’s named simply from the fact that is looks very much like the mane of a lion, but the health benefits are anything but simple. It has amazing cognitive properties and was once used by Buddhist monks as a way to increase their focus during meditation.

Chaga: Chaga mushrooms are among the most antioxidant-rich mushrooms available. The Chaga’s rich antioxidants helps to boost the body’s immune system and flush any toxins out, allowing the body to work more efficiently without getting sick.

Cordyceps: Cordyceps mushrooms directly support the adrenal glands, providing a natural energy boost with a “mid-day slump” or crash later. When combined with coffee, it can increase the energy output. Products like the Four Sigmatic Mushroom Coffee don’t need as much actual coffee in it as a result.

Reishi: Like Chaga mushrooms, Reishi has a great immunity boosting benefit. The difference is that reishi protects the immune system from viral attacks, and has been known to treat swine flu, avian flu, and breathing conditions like asthma and bronchitis. It can also help protect the heart and maintain blood pressure levels.

Are There any Concerns Regarding Allergies?

All of the products that Four Sigmatic makes are organic, vegan, and Whole30 friendly. They don’t contain any gluten, wheat, soy, or peanuts. 

The mushrooms included are not psychedelics, so you don’t have to worry about getting high or unnaturally addicted to it.

However, people who have any mushroom-related allergies should be extra cautious, just based on the fact that the primary ingredient in many of their products are mushrooms. 

If you are allergic to mushrooms, no matter the kind, you should consult your physician first before consuming anything with mushrooms in it. The same goes for women who are pregnant or nursing.

What is Edible Skincare?

Four Sigmatic makes two skincare products that they have labeled as edible skincare. But what is that? 

Edible skincare are products made out of ingredients that are also safe for consumption, not just for the skin. 

The Mushroom Face Mask & Toxin contains cacao, reishi, chaga, activated charcoal powder, panax ginseng, gotu kola, cinnamon, nutmeg, ginger, citric acid, and sodium bicarbonate. Use it as a face mask to clean and exfoliate your skin, or drink it daily for overall wellness and stress relief.

The Superfood Serum contains avocado oil, organic olive fruit oil, reishi spore oil, Tsubaki seed oil, grapefruit peel oil, frankincense oil, honeysuckle flower essence, Japanese honeysuckle flower extract, tocopheryl, and jojoba seed oil. Use on the skin for cleansing and toning, or consume for overall wellness.
