Four Sigmatic

Product review: Four Sigmatic

Four Sigmatic is a brand of mushroom-based beverage blends. The company was born in Finland and now operates from the US. Their beverage blends are highly regarded in the biohacker community and are endorsed by influencers such as Tim Ferris, Ben Greenfield and Emily Schromm.

What are functional mushrooms

Mushrooms have been used for their nutritional and medicinal properties for centuries in several cultures (1, 2, 3). Thus, many mushrooms can be considered “functional”.

Nutrients in mushrooms

Mushrooms contain:

  • carbohydrates, mainly polysaccharides (i.e. many sugars) which act as dietary fibre and prebiotics (i.e. food for gut bacteria), etc. (3, 4)
  • amino acids (3, 4)
  • polyunsaturated fatty acids (3)
  • other molecules such as ascorbic acid, carotenoids, tocopherols (3), triterpenoids, nucleosides, phenolics, and flavonoids (4)
  • vitamin D, especially mushrooms that have been irradiated with UV-B and UV-C light

Benefits of mushrooms

There is evidence that mushrooms do or may have the following benefits:

  • antioxidant (1, 2, 3, 4), antimicrobial (1, 3, 4), anticancer and anti-inflammatory properties (3, 4)
  • help relieve fatigue in the muscular system, body antioxidant system, cardiovascular system, hormone system, and immune system (4)
  • protect the intestinal mucous membranes, support the immune system and help regulate blood lipids (3)

It’s important to note that most experiments have been carried out in animal models (4) and that not all mushrooms have the composition or properties.

Four Sigmatic mushroom beverages

Taste test

I like the taste of all of the beverages taken with hot water. The mushroom coffee tastes like regular instant coffee to me; having said that, I have a pretty good tolerance to bitter flavours. A friend of mine tried the coffee with water but had to add milk to make it palatable.

The hot chocolates do contain sugar (coconut sugar is sugar), so they’re belong in the treat category for me. They are pretty good with hot water or unsweetened almond milk and, optionally, collagen peptides.

Functional test

I have bought a few boxes of Four Sigmatic products but I don’t take them consistently. Having said that, I must admit I have not felt any sort of supernatural powers after using them. However, I don’t discard the possibility of these products having beneficial effects on health, potentially upon regular consumption.
