Green box. Four Sigmatic SHIELD organic coffee. I love this coffee. Really enjoy a cup. And i am a tea drinker normally! Highly recommend.

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!!

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!

Never a membership fee, always 20% OFF subscription products and FREE shipping as well! They often send samples and freebies, everything's organic. Anyone that's worried about their cognitive function should really give the FOCUS blend a try! Even if, like me, you hate mushrooms!

I’ve purchased many different products from this company and it’s definitely the best! I love the mushroom teas and coffees and I thought they were going to taste terrible but they surprisingly weren’t. I feel like that is obvious but if you’re purchasing these products it’s for the for the health benefits and not the taste. Honestly, if they did taste like trash I’d still buy them. Lions Maine is my go to but I love them all. Recently they came out with a protein and I’m obsessed!! I’ve never found a protein powder that hasn’t hurt my stomach until this one. I thought it was just me and my weird stomach but my friend said the same thing!

I drink the lion's mane coffee occasionally and it does wonders. I am a STEM student so I need my brain to function at its fullest and the shrooms really help out. No taste whatsoever :) I do the cold brew method. I hope they will come out with a decaffeinated version as well.
