I bought this product couple months ago and I love it, it's a pity iHerb doesn't have complete line of Real Mushrooms.
I also have the powder of both Turkey Tail and Reishi, also the blend 5 is awesome, tastes like coffe. I love it, I mix it with Matcha.
Just hope iHerb can have more products.
To be determined how effective these are: I bought these because this brand seemed reputable according to Consumer Labs, and another more popular brand only had mycelium. This one is supposed to actually have mushroom, which is nice.
