I am late to this post but wanted to share my peculiar experiences w Mushroom coffee too many times to be coincidence. I started enjoying mushroom coffee at 48-49 years old. Everytime, I drank mushroom coffee on a regular basis, I would get a stuck period which would negatively impact me due to adenomeiosis. I'd just had prolonged painful sleepless PMS and a very late period. This was upsetting because the coffee made me feel better cognitively which I work a lot so I thought I found a solution to my tiredness until this happened. I kept risking it and trying to chalk it off to perimenopause but it happened every single time. I kept trying to find research on it but very little available. I think it's worth looking into. I did find something in German (yes German) about either Chaga or Lions Mane effecting the pituitary gland but I can't recall which one. I wish there was more research so I know what mushroom to avoid and I could go back to enjoying my mushroom coffee. Anyway, it must effect our hormones somehow. We need more research by the science community.
