Customer Reviews
Ground mushroom coffee is a staple!
my ground mushroom coffee subscription saves me about 15% and it's easy to change or cancel.
Decaf Mushroom Coffee is my jam!
so much better than Ryze, for real! I got the Decaf Mushroom Coffee and it's legit delicious, especially for $27.99 a bag. the only thing is, i wish their discount codes were easier to stack, but still totally worth it! gonna tell all my friends about this. ๐
Liked the Mushroom Coffee
So, I decided to try that Mushroom Coffee with Ashwagandha. Heard good things, you know? It got here pretty fast, like a week after I ordered. The coffee itself was surprisingly nice, didn't taste weird at all. Felt a bit more chill during my work day, which was cool. Overall, a solid experience, I'd probably get it again.
Good coffee, fast delivery
I bought the Mushroom Coffee with Lion's Mane. It shipped quickly and arrived in 4 days. The coffee tasted good, not too mushroomy. I had no issues with the order. Simple and effective.
Decent value on coffee
I was looking for a good deal on mushroom coffee and saw Four Sigmatic's Mushroom Coffee Dark Roast. I managed to get it with a first order discount, which made the price pretty competitive. Shipping took about 6 days to reach me in California, which was okay. The coffee itself was fine, a solid dark roast, and I didn't notice any mushroom flavor. For the price I paid, it felt like a worthwhile purchase. I'd consider buying it again if there's another good offer.
Love the Creamy Cacao Protein!
Oh my goodness, I just had to share about the Creamy Cacao Mushroom Protein I bought! It is absolutely fantastic. I mix it into my morning smoothie and it gives it such a rich, chocolatey flavor without any weird aftertaste. Plus, I felt really good and energized after. The delivery was super quick, got it in about 5 days, which was great since I was so excited to try it. I'm definitely going to buy this again and I'm telling all my friends about it. Seriously, if you're thinking about it, just do it!
Four Sigmatic Community Discussion
Share tips, ask questions & help fellow shoppers save more
Thinking about getting the protein powder, but is it actually good for gut health? Saw some competitors making similar claims.
Does anyone know if they allow stacking coupons? I have a first-time buyer code and also saw one for a free frother, trying to maximize the savings.
How long does shipping usually take to, say, Seattle? Want to order some for my mom's birthday next week.
Hey guys, thinking of trying the mushroom coffee. Does it actually taste like mushrooms, cause I'm not really into that.
