  • Convenient single-serve packets
  • Smooth, non-chalky protein texture

  • Polarizing earthy mushroom taste
  • Occasionally weak coffee flavor

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.

  • 10/10 feel the adaptogens in these teas. Love the turmeric latte for inflammation and the cacao with reishi for bedtime. Also a great replacement for sugar cravings.

  • Really big fan of their coffees and hot chocolate. As someone who is sensitive to too much coffee and regularly only drinks half a cup, I found the light nature of Four Sigmatic coffee sachets very drinkable and light.

    The products are still quite expensive and not sure the packaging is the most sustainable.

  • I keep wanting mushrooms to change my life but, so far, mushrooms haven't changed my life. The world is stressful. Sometimes I have a hard time sleeping. Sometimes I have a hard time staying focused. I've tried Four Sigmatic's instant coffee and their bedtime hot chocolate. Let's get the coffee out of the way: it doesn't taste good. I'm someone who likes instant coffee (team Nescafe, and Starbucks Via is amazing) but this still tastes like what I'd find in the back of my grandmother's cabinets. The bedtime hot chocolate is pretty good, though! Relatively low in sugar and it tastes nice. Unfortunately, I don't notice the mushrooms doing anything for me beyond what the non-mushroom equivalents would do.

    More mushrooms? I dunno.

  • Good brand with a variety of fun products. I like that there are a ton of different options for later in the day drinks that aren't just tea Also some of the packs are great for travel

  • appreciate what they’re doing, but as a coffee lover this does not come close. no, i am not a white chocolate caramel girlie so its not the sugar i’m missing. its more so that it tastes like dirt and is very bitter but not in a fun coffee way.

  • I’m not a fan of mushrooms but they do have great health benefits. I love Four Sigmatics coffee and their hot chocolate. Tastes really good and overall makes me feel more refreshed for the next few hours after consuming.

  • This stuff tastes disgusting. I couldn’t get it down. I don’t like mushrooms, so if you don’t like mushrooms, don’t even try.

  • Yummy flavors. I think you would need to be more consistent with taking it to have real results but it's a nice treat when I get those single serve packets and they are pretty yummy with some steamed milk

  • These are great tasting and high-quality adaptagenic blends that make it tasty and easy to get in my adaptagens. I've listened to a few podcasts talking about the products and the quality of the ingredients which makes me feel really comfortable consuming their products compared to other sources. I personally LOVE the hot cocoa mix before bed. it's a great ritual for me to help me wind down at the end of the day.

  • Really like the flavor and enjoyed a nice chocolate drink to calm me down before bed

  • I have tried most of the coffee blends and they all are amazing. My favorite is the "Think" Lion's Mane. Not only does the taste beat other brands for me but the way it helps me navigate my day is incomparable. I notice that I don't get tired mid day like I do with other coffee brands.

    The packaging could use some work. If I want to pour the coffee grounds into another container I usually use scissors instead of the openings the package has or else the grounds are everywhere.

  • I tried the green mushroom blend that I mix with chai. The taste is very unnoticeable which works for the drinks that I make, so no complaints. I'm not sure I notice any differences, however.

    Feedback

    The packaging could be better. The green tin comes with a little plastic spoon which always gets lost in the powder.

  • I've tried their hot chocolate and the only way I can describe it is the most chill hot chocolate I've ever had. It makes you feel so calm after drinking it, I save it for those cozy winter nights where I just want to get on the couch and watch tv. It really is a special drink.

  • The individual packets make them super convenient to take on the go. I cut down my coffee intake a few months ago and these have helped me immensely! Love the chai flavor

  • Unique product that is a great alternative to afternoon coffee for me. High quality ingredients.

  • Love the matcha latte flavor. It mixes well, is creamy and a hint of coconut and sweetness. Not sure I feel all that different/better after drinking them but are enjoyable and feel like a treat.

  • Got the ground coffee and like it a lot! Drinking it plain, it definitely has a district earthy type taste, but can't really tell if you add creamer with it.
