Four Sigmatic – Cashback, Rebates & Rewards

I absolutely love this company! I've been ordering their coffee for years and it's the only one that actually feels good on my stomach, after years of GI issues. I am so grateful to have discovered Four Sigmatic. Thank goodness! I highly recommend this brand if you've had any GI issues, as the addition of functional mushrooms makes this my best choice for my health, while still loving the taste!! Best Coffee Choice around!!

Good coffee and I can’t move on with my day without it. They have very nice customer service too! Removing one star because their products are insanely expensive.

I’ve only ordered their Functional Creamer for my keto coffee. The powder was in clumps when I opened it so I had to break them up with a spoon to get it to a fine powder again. It’s supposed to make your coffee like bulletproof coffee but it really didn’t. Just use the actual ingredients (MCT oil and butter) to make real bulletprooof coffee. I’m on keto and intermittent fasting and it did keep me from breaking my fast so in that sense, it did work for me. It has no taste and I can’t really tell that I have anything in my coffee. I used the scoop and the portions on the package per cup. It’s not much. I imagine if you use a couple of tablespoons, you can tell it’s in there. It was a $30 canister and I’m almost out and I prob won’t be ordering again.

Best costumer service ever

Love Four Sigmatic's mushroom coffee blends! I am not much of a coffee drinker because of the taste of the roast. However, when I tried Four Sigmatic coffee blend I was hooked. I have ordered regularly in the last two years and now tried their protein powder and love it! Other protein powders that are made vegan give me stomach upset, but not the one from Four Sigmatic. Five stars all the way!
