Four Sigmatic Reviews

This company is genuinely fantastic! I've been buying their coffee for years now and it's the only one that doesn't upset my stomach after dealing with digestive problems for so long. Finding Four Sigmatic was a real blessing. I'd really recommend them to anyone who struggles with GI issues. The functional mushrooms in the blend make it perfect for my health needs and it actually tastes good too. Honestly the best coffee option available.

Horrible experience from start to finish. Ordered a protein powder that showed one thing online but arrived missing the main mushroom ingredients I paid for. Complained and got nothing but silence for weeks. Eventually had to message them on another platform just to get a response. They offered to send a replacement at no charge, which I appreciated, but when I asked to confirm it would have the proper ingredients they ghosted me again. Got a shipping notification saying it was delayed, then six weeks later the exact same wrong product showed up. Gave up after that. They clearly treat international customers like second-class citizens compared to US customers.

The coffee is really great and it's become essential to my daily routine. Their customer service team is fantastic too. The only downside is that the pricing is pretty steep, which is why I'm dropping a star.

Only tried their Functional Creamer since I use it for keto coffee. The powder came clumpy and needed a lot of work to break down properly. It claims to be like bulletproof coffee but honestly just making it with actual MCT oil and butter works way better. On the positive side, it did help me stay in my fasting window. The taste is basically nonexistent and you can barely tell it's there unless you load up on it. At thirty bucks a canister, I'm almost done with mine already and probably won't reorder.

The product itself is pretty mediocre, but what really bothered me was the customer service. They completely ignore unsubscribe requests and it feels like dealing with a spam operation. Just not worth my time or money.

I keep coming back to this company because their products are legitimately the best. Their mushroom teas and coffees taste way better than I expected them to. Obviously you're not buying these for flavor, you want the health benefits. Honestly even if they tasted terrible I'd still purchase them. Lion's mane is my go-to item but their whole lineup is fantastic. Their new protein powder came out recently and I'm absolutely in love with it. I've never found a protein that doesn't upset my digestive system until this one, and a friend of mine reported the same thing.

This company is absolutely incredible and I've tried tons of their stuff. The mushroom coffees and teas are surprisingly delicious even though I figured they'd taste awful. But really, when you're buying these products you're after the health perks anyway. Lion's mane is my favorite go-to but I genuinely love everything they make. They just released a protein powder that I'm totally hooked on. It's the only protein I've ever found that doesn't wreck my stomach and my friend has had the exact same experience.

The lion's mane coffee makes such a noticeable difference and I drink it fairly regularly. As a STEM major, I depend on my cognitive function and the mushroom blend really comes through. Zero flavor, which I appreciate. I typically use the cold brew method. Would definitely be interested in a decaf option if they offered it.

I have the lion's mane coffee from time to time and it genuinely works wonders for me. As someone in STEM, I really need my brain performing at peak capacity and these mushrooms deliver. Doesn't have any flavor which is fine. I usually make it cold brew. Would love if they released a decaf version at some point.

Tried both the mushroom coffee and the lion's mane elixir and gave them a fair shot. Unfortunately the smell and taste just weren't for me, which is disappointing since everyone says how beneficial they're supposed to be for your health.
