More stable energy but taste isn’t for me

It does what it says less jittery energy crashes but I mix it in smoothies to mask the earthy flavour.

So much more stable energy

Maitake has really helped level out my afternoon slumps. I’ve been taking it for a month and feel way more consistent throughout the day.

That’s exactly the kind of steady energy Maitake is known for. Afternoon slumps can really drag you down, so hearing you’re feeling more consistent all day is a win. Keep at it and enjoy that balanced rhythm.
