I have used Lions Mane off and on for about 7 years. When I’m stressed or working hard with clients my mind tires and I forget details. A few days of 4 caps a day and then down to 2 caps a day and the brain fog clears. I’m 70, work full time, exercise and eat well but recently I was forgetting things (mostly my nouns and client names) I find lions mane is giving me back my edge.
Can’t recommend Purica products highly enough. We use Recovery to great effect, physically, as well.

Two capsules in the morning gave me an immediate mood and energy boost. I had restless sleep and felt edgy and revved. I stopped taking it after about 10 days because the edginess didn’t subside. No other side effects.
