This is my first time taking turkey tail. I'm taking it for improved energy and fighting viral and bacterial infections. I have ME/CFS and I've been struggling with a virus hitting my throat, glands, and energy continuously over the last 2 months. What is really noticeable and striking is that every time I've taken the turkey tail, within a minute, the discomfort in my throat and glands disappears. Every single time. I have no idea why - why so instantaneous? But it's great - way better than ibuprofen - so I'm going to continue with it. As for improved energy, it's difficult to say if it's making a difference. I am feeling a bit better but is that because I'm also meditating and getting better sleep?
