actually have to check if i get enough via food. But it does help taking Turmeric and Black pepper with it. and in foods too. Love ayurveda herbs and foods / spices. About PQQ i feel it takes away muscle pain and brain fog. Used for years and notice when i dont take it. So no doubts. :) YES mushrooms are awesome. Reishi, Chaga, Cordyceps, hehe and food mushrooms. LOVE all Shrooms :D
