I’ve cycled on/off lion’s mane a few times to see if it made a difference and it’s immediately noticeable when starting it again. I’m sharper, my memory is better, it really does provide me with the neural support they claim.
I seem to be sensitive to all things mushroom related, so take my experience with that in mind. The recommended dose is 1 ml twice per day and I could only handle 9 drops once per day. The first time I took 1 ml, it caused a lot physical tension, it almost locked up my hands, which was really odd. Had to titrate it down to a dose I could handle.
