Magic Coffee with Lion's Mane Mushroom

I'm a bit fussy about my coffee and usually stick to Illy as its my favourite. However as coffee is generally not the most healthy of beverages and I drink 3 cups a day, I've been keen to try a healthier coffee.
I came across this Magic Coffee during some research and the benefits of Lion's mane mushroom are well known, so I gave it a go.
Looking at the manufacturer's website I can see that its tested for purity and ground and packed in the UK which I like.
The taste is on the mild side, but it does say to add 3 heaped teaspoons to 150ml and I use a big mug so I might have to put an extra 1/2 - 1 teaspoon in.
I was worried that the taste might be too 'mushroomy' but you can't taste mushroom at all but it does have a slight 'earthy' taste which I quite like.
All in all, it makes an enjoyable cup of coffee, there's nothing unpleasant about it and the health benefits are what makes it for me so I'll be sticking with it for the foreseeable future.
I should say, I don't seem to get the jitters half as bad with this coffee as I do after my third cup of Illy!
