Having trouble sleeping, or wishing you could have an extra boost of focus when you wanted one? Then you’re definitely going to want to try Four Sigmatic. In this Four Sigmatic review, we’ll cover our personal experience with their products, specifically their Lion’s Mane Mushroom Coffee and Reishi Elixer.
What is Four Sigmatic?

Four Sigmatic is a company founded in Finland specializing in superfood products, particularly their mushroom coffees, teas, and elixirs. The name comes from the idea of four sigma foods: foods that are so healthy for you that they’re four sigmas or standard deviations above the average food. In other words, the company is focused on superfoods in the top 0.1% of all possible foods when it comes to nutrition.
The company has expanded their product line to plant-based protein and skincare as well, and is highly reviewed and endorsed by high profile personalities like Tim Ferriss.
Where can you buy Four Sigmatic Products?
The company sells their products on Amazon and on their own site. We purchased our products on their site and had no problem with shipping. As a bonus, the products were delivered in a very fun mushroom themed box (as pictured).
Our Four Sigmatic Review
For this review we’re going to be focusing on our buying experience, as well as their Lion’s Mane Mushroom Coffee and Reishi Elixer.
Shopping for Four Sigmatic

We shopped on foursigmatic.com, and we have to give the company big props on their site layout. While most sites organize their layout by product, Four Sigmatic organizes their site by routine, focused on morning, afternoon, or evening.
Checking out was a breeze and you can even create an account to manage your order or start a recurring purchase or subscription.
If your more comfortable shopping on Amazon, Four Sigmatic has set up an excellent shop there as well, but let’s get to the good stuff.
Our Reishi Elixir Review

The Reishi Elixir is promoted as a tea that you should take before bed to improve sleep or use to calm down. After all, the name on the package says ‘chill’.
What are Reishi Mushrooms?
Reishi mushrooms are mushrooms that grow on the sides of trees in hot climates in Asia. They’ve been found to have tremendous positive health benefits, including immune system support, cancer prevention, fighting fatigue, and all the benefits of antioxidants.
Our Review
To prepare the elixir you just add it to hot water. It mixed well and tastes just fine, about as good as a normal herbal tea. I also tried it with almond milk, which worked well. Did it improve my sleep? Not quite as well as something like Nyquil, but I did notice that I was able to fall asleep much quicker.
My girlfriend’s mom was having trouble sleeping due to a hamstring injury, and she swears by the stuff, so much so that she was concerned that there was a much stronger drug / ingredient than organic reishi mushrooms in the elixir. We ordered more specifically for her, and anytime she’s having trouble sleeping she turns to her trusted Reishi Elixir.
Our Recommendation
While I enjoyed the product, it’s fairly pricey. As of writing the Reishi Elixir was listed for $28 on Amazon. I wouldn’t buy it for myself, but I don’t have too much trouble sleeping to begin with. However, my girlfriend’s mom loves it and does have trouble sleeping at times, so we’re continuing to order it for her.
So, if you don’t have trouble sleeping, you can definitely get by without it, but if you do have trouble sleeping, you should definitely give it a go!
Our Lion’s Mane Mushroom Coffee Review

The next product in our four sigmatic review is the lion’s main mushroom coffee. The lion’s mane coffee is the drink you turn to when you know you need to have a productive morning.
What are Lion’s Mane Mushrooms?
Lion’s mane mushrooms have a host of nootropic benefits, including helping fight against dementia as well as helping to reduce anxiety. The mushrooms grow in Asia, Europe, and North America and are called lion’s mane because yes, they actually resemble a lion’s mane. Plus, the coffee also includes chaga mushrooms, which come with their own host of benefits.
Our Review
Four Sigmatic’s Lion’s mane mushroom coffee is also prepared with hot water. It goes great with a non-dairy creamer. The coffee has an incredibly distinctive taste. It tastes like coffee but has a distinct umami flavor as well, which tastes a little like soy sauce. I know, coffee and soy sauce sounds a little gross, right? Don’t knock it till you try it though. While I know my girlfriend didn’t love the taste, I really liked it.
But enough about taste, you want to know how much it boosts your focus or productivity, right? For me, it definitely felt like I’d just drank more than just one cup of coffee. Tim Ferriss actually recommends drinking only a half cup to start, because it’s so potent. I definitely felt more productive and focused, but I also feel like I could develop a tolerance if I drank a cup every day.
Our Recommendation
Four Sigmatic’s Lion’s Mane mushroom coffee is a great option for those mornings where you need a pick me up. It’s currently $13 for a 10 pack on Amazon, so again it’s not cheap, but I think it’s a great option for an occasional boost. I highly recommend this product and use it when I need to perk up.
Our Overall Four Sigmatic Review
Overall, Four Sigmatic sells excellent products, and while they’re a little pricey, you get what you pay for. While we’ve only reviewed the reishi elixir and lion’s mane coffee, we look forward to reviewing more of their products in the future.
