for me it's not really much. It's like a teaspoon or so in a glass with maybe 4-6 oz of water twice a day. Like Ovaltine chocolate in a small glass of milk. I guess I'm showing my age with that. In pill form, it seems like a lot because of the numbers, but powder not so much. From reading on google, there have been some studies using Turkey Tail for cancer. Again, I'm just going by the quantity used in the studies.
Do what makes you feel good and stay safe and healthy.
