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.

Nice! But, super overpriced. I rarely feel good about what I'm getting in exchange for what they're asking. Idk why. Somehow, the four sigmatic experience feels like the juice isn't worth the squeeze, although it's nice in a pinch.
Not a fan at all. Very unpleasant taste and not nearly close to the best method to get all these exact benefits into the body.

I am absolutely OBSESSED with the Focus Blend and was in a bit of panic when it went out of stock earlier this year. In my attempt to find a substitute for the Focus Blend while it was out of stock, I tried OM Mushroom's blend but did not find that blend to be comparable at all. I typically mix the Focus Blend in my morning coffee and I do feel a difference when I do not add it to my coffee; I feel less inclined to check my phone and actually focus on work. It also mixes in very well into hot beverages (when using a frother) and I dont find it settling tot he bottom, like other blends I have tried. Highly recommend as a morning boost!

I've bought their Mushroom Cacao Mix with Reishi over 6 times. Whenever I have guests over and we want a nice warm drink to end the day, I make some for them. Every. Single. Time. They ask how I made it. So, I always give packets out for them to take home and there I go, buying some more. If I could give it 10/10 I would!
I loved the Four Sigmatic Focus Shot, in particular; it really worked for me when few things do! It's a bit of a splurge, but the ingredient blends are really good, and the taste is pleasant as well.

Please bring back the Focus Shot!

Coffee afficionados will scoff at this product but I was pleasantly suprised. My cup had a slight aftertaste but not unpleasant. As far as functional drinks go, this one feels like it actually accomplishes its promise. This isn't an instant change, you need to drink it for a certain amount of time and the benefits are subtle. I've had a cup a day for 3 weeks now and feel pleasantly alert. Whether or not this is placebo I'm not sure but at least the brew feels nice.
Not a coffee drinker, but this is the only coffee product I’ve had over the last few years because it doesn’t give you the jitters…which is magical. Just not a huge fan of the taste (but could be because I don’t really love coffee overall?)

Great product in doing what it promises!

Very good coffee products, I enjoy all the mushroom coffess they sell that do not have any sweeteners in them.

I use a packet of the lion's mane coffee in my coffeepot every day...hoping to keep my mind sharp! It is bascially instant coffee (added to my drip coffee machine) and would not know it is there other than the amazing adaptogens I'm sure it is adding. I have also tried the various bulk coffee items, they are okay but I prefer my usual coffee blend, just personal preference, nothing against the Four Sigmantic mushroom coffee blends.

I did not like the taste of the lions mane. I really wanted to because it would have been a great way to get my brainpower nutrients in, but I just did not enjoy it.

Improve the taste

I love the idea but I didn’t love the taste of some of their products. I’ll have to give it another try.
I really liked the several varieties of mushroom powders I've used from them.
Delicious
I've used several of their mushroom powders and drink powders. I've really liked most of the flavors, though some lean a little too sweet for me. I didn't notice too much of a 'difference' in terms of how I felt or stress levels with the products, but it was a nice ritual to feel like I was doing something healthy for myself.
Feedback
Some of the powders are a bit hard to mix in, and occasionally seem a bit gritty.
I don't dislike their products.... however, not sure I've seen a huge difference with mushrooms or an affect of them. Maybe it's doing something, but wouldn't repurchase. I did like their instant coffee though, it was tasty and convenient!

Four Sigmatic is great. They are some of the OG's of the modern times for helping the average consumer get medicinal mushrooms in their everyday routines. I love being able to just add a lions mane packet to my coffee.
Pioneers in the functional mushroom space. I feel like every time I go to the grocery store they have a new product. So far everything I've tried has been tasty!
Feedback
I feel like the branding/packaging could use a little rework to have more shelf appeal? Especially now that the mushroom space is getting sooooooo competitive.
I really enjoy these products. I think their mission is cool. They started the mushroom/super foods trend pretty early, which shows they are really passionate about it rather than it just being a trend. I love their hot chocolate one. Also love the individual packaging, it doesn't go bad.

Mushroom hot cocoa is a great night time alternative to a natural great sleep!
I really love their coffees. It's some of the best instant coffee I've ever had and a bonus that they contain functional mushrooms. That being said, I don't like that most of their products come in single serving packets. It's not at all sustainable.
Feedback
Offer your products in bulk bins with scoopers so that there isn't so much waste. Or at the very least make your packaging compostable.
I’ve tried many Four Sigmatic items-the instant mushroom coffee is my favorite. The adaptogen mixes are good, but I don’t notice a difference when I take them.
