Four Sigmatic earns mixed-to-positive reviews: many praise its instant coffees, cacao mixes, matcha, and plant-based protein for smooth texture, convenient single-serve packets, and calmer, jitter-free energy or improved focus, while others report weak flavor, gritty/clumpy mixing, and no noticeable functional effects. The brand is lauded for variety and quality ingredients but criticized for polarizing taste (earthy, mushroomy), inconsistent dissolution, and some blends feeling too sweet or bland.
AI summary based on Thingtesting reviews
Not sure if mushroom coffee is for everyone but it is for me! The flavor is wonderful, very coffee like and just slightly earthy and the feeling is even better. Less jittery, still energized. I also love the ease of the single coffee packets.

Four Sigmatics Matcha is my favorite home matcha. It’s easy to make. You just add 8 oz of hot water and mix. I usually add oat milk to make it cooler. I also like the instant mushroom coffee because it’s just as easy to make and I believe mushrooms help my health journey.

I was skeptical of mushroom coffee, but I have to say I was pleasantly surprised how much it reminded me of coffee and how little it reminded me of mushrooms. I am still in the small sample size, and I don't know if I would ever Completely forego coffee, but Sigmatic is definitley making a worthy substitute.

They offer great specialized mushroom-based drinks! I really like how they come in small packages and are travel-friendly. My favorite so far is the mushroom cacao mix! It's definitely something that you've got to try!

It is a fun and unique concept, but unfortunately the taste is not very good. Some are better than others, but so far, none of the ones I’ve tried have been worth re purchasing. The cacao one was hard to drink, and very over priced. Honestly would be better off buying a high quality mushroom supplement and enjoying real chai or matcha.

I'm currently trying the Defend mushroom mix. I've been adding a scoop to my morning coffee for approximately 4 days now. The powder blends well in my morning coffee with a barely noticeable taste. The taste can be described as earthy, not bitter or grainy like some of the other mushroom supplements I've encountered. I do not notice much of a difference in taste with my coffee. I ordered from Amazon, and it shipped very quickly. I added a mushroom mix to my daily routine to help with chronic fatigue. So far, I haven't noticed much of a difference in my energy levels. I haven't been taking it very long. I can say I haven't gotten sick, which could be due to this mushroom mix or not. The mix doesn't upset my stomach at all, which is nice because my stomach can be volatile at times. I'm eager to try some of their other products.
Feedback
The pricing is decent for the powder. It's a bit offputting the can is about half full. However, it says there are 30 servings, so I'm sure it's just settling and filled by weight. I would've like to see a difference in my energy levels.

I don't know that I've noticed particular benefits from this product, but I also don't drink it super regularly. With that said, I think the products taste good for what they are, so if you're looking for the benefits, you won't be disappointed with the flavor.

BEST PROTEIN POWDER EVER EVER! I love the Four Sigmatic plant-based protein powder and use the unflavored powder daily! I like to put it in my smoothies or just mix it in a cup of water when I need a quick boost before or between meals. There is no gritty texture which is a HUGE win in my opinion.
Feedback
This brand is great for people who are curious about introducing more adaptogens and mushrooms to help with brain function and overall body health!

Honestly good advertising but it's just overpriced coffee and mix.
Feedback
I don't like the overall quality. The website is nice, but nothing worth the price honestly.

Four Sigmatic protein powders trust me on this one. I have gone through so many plant proteins that just have that dry aftertaste. But Four Sigmatic is the smooth protein powder that I love to include in my smoothies or just on its own blended with water. My favorite flavor is chocolate!
Feedback
It is on my list to try more products from Four Sigmatic. The protein powders are my favorite to add to smoothies, overnight oats, oatmeal, or just blended with water and ice. This is my go-to protein powder from now on! Highly recommend.

After struggling for some time with brain fog, I decided to do some research into supplements I might be lacking. After this, I purchased my vitamins and long with them, I purchased a container of their "focus" blend. Once I ran through a couple of containers, and had seen much improved concentration and memory, I decided to go without it for a couple weeks to see if it was the powder or the vitamins that made a difference. Turns out, while I was still taking the vitamins and no powder, I had brain fog again. I have since repurchased this product for a third time and will continue to repurchase. I have known about this brand since around the time they launched and have tried their coffee products in past years. I would recommend anything from this brand to anyone.
Feedback
I honestly don't have any improvements to talk about from this brand. They know what they are doing and mushrooms are so powerful!

I like the single serve coffee packets the best. We always have them at our coffee bar and it's a fun option for guests to try if they've never had mushroom coffee. We usually have to restock every other month or so. I don't notice any effects above and beyond normal coffee but I wish I did!
Feedback
Concentrate or iced coffee formats that are ready to serve would be amazing, I would give it a wholehearted second try that way rather than just stocking it.

I love the concept of a mushroom cacao version of a hot chocolate before bed and “elevating your bedtime routine” but I’m not sure of the effect of this product. I am a good sleeper anyway and haven’t noticed any discernible effect on my sleep which I suppose is a good thing. The taste is surprisingly innocuous - if you didn’t know it had mushroom extract in I don’t think you’d pick it out as tasting different from a normal cacao drink. Without noticing a bit effect from the active ingredient, it feels a bit expensive to me as buying organic cacao powder or 100% cacao buttons and making that a drink would be considerably cheaper. The packaging is well considered and fun to use and read (see photo) and I am enjoying working my way through the pack. I’d recommend to a friend interested in exploring the power of mushrooms as everyone is different and they may experience the product differently to me.

Variety of flavours perhaps by addition of other herbs/spices that have aromatic and/or medicinal properties

I received this instant coffee as a gift from a friend who insisted I try it. I was apprehensive about for us to try this, but once I did, it was really great, especially when I was in a hurry in a pinch it is best if you use like a mixing tool or froth or to really get it mixed together, but the taste was really good and you can also put your favorite plant-based milk in and enjoy!!

Great products, and so many different ways to incorporate shrooms into your daily life!

I've really enjoyed adding this into my morning routine. Four Sigmatic is super tasty and has perfect benefits that I look for in mushroom-based drinks.
Four Sigmatic coffee beans might have health benefits from the mushrooms but I find it to be almost undrinkable. Somehow their instant coffees are much more palatable and also easier to prepare to get in your daily dose of shrooms. I also like the mushroom matcha latte mix when using two packs mixed with non dairy milk to make it matcha-y enough for my taste.
Interesting concept, but I’m a coffee drinker through and through. These didn’t make the cut, but would be great if I ever needed to reduce my caffeine intake.
I've been a fan of Four Sigmatic since early in the mushroom-based product days. They were the first to really make mushroom-based coffee, hot chocolate, and chai tea alternatives trendy, increasing their product mix to include a variety of additive functional benefits. The chai latte, in particularly is a great pantry staple.

Love their mushroom coffee and mushrooms blend. Their monk fruit based coconut cream tend to clump up and doesn't dissolve quite well.
