Real Results From Coffee Drinkers Who Were Skeptical First
Right stimulus, right focus.
I use it as a pre workout and it gives just the right amount of stimulus plus focus. I have happily suggested this product to many clients.
Clears the brain fog.
I use it as an addition to my morning coffee and I can feel a difference in my mental health. I think it helps clear out the brain fog in my older, I'm 68, brain.
A coffee snob's honest take.
I'm talking organic, freshly ground beans in a French press every time. I was open to the pre-ground to try the coffee/mushroom combo. Short story — I love it. The taste, the noticeable mental clarity as well. You won't be disappointed.
No more mid-day slump.
I switched about three months ago and haven't looked back. I get a smooth, steady energy through the whole workday — no spike, no slump. This is my coffee now.
More awake than regular coffee, no crash.
Delicious, makes me feel more awake than regular coffee and less dehydrated. Plus I don't feel a crash.
Constant energy, no crash.
I've noticed a complete swing in my energy levels throughout the work day. I'm usually an avid dark roast coffee drinker. The Lion's Mane dark roast is a perfect alternative — constant energy and no crash. Will be purchasing again!
Tastes great, no jitters.
Amazing coffee! Tastes great and doesn't give you the jitters.
No heartburn like with regular coffee.
Excellent taste and I don't get heartburn like I do with regular coffee. Thanks for a great product.
Doesn't upset my stomach.
The coffee is super smooth with a great taste and it does not upset my stomach like other coffees.
Converted big time.
I picked up a couple bags on a test, thinking I'd probably put them in the back of the cupboard. Well now I'm out and will be stocking up next time. It not only tastes amazing, the mushrooms create a really well-rounded and mellow taste. I also don't get that caffeine bounce like other coffee. Converted big time!
Already increased our monthly order.
We've quickly learned to look forward to receiving our box of Four Sigmatic with Lion's Mane and have already increased our monthly order. While I'm pleased with how it's grown and harvested, and the Lion's Mane extracts, we would be buying the coffee anyway.
Tastes great, no jitters.
Amazing coffee! Tastes great and doesn't give you the jitters.
