Lions Mane, In my experience it really does sharpen the brain helping with clear positive thought (Using them for 6 months)
I am already aware of the genuine benefits of mushrooms to health but lions mane was a bit of a gamble. Seemed too good to be true, and how long would i have to wait. Short answer the really work and its pretty much immediate, feeling the benefits after a day.
Just like many of the reviews you read online, I had the typical symptoms of very vivid dreams at first (nothing unpleasant, just interesting - i don't dream - at night :). I tried taking two a day but this created an effect like caffeine high. So have worked out 1 pill just after tea around five really helps for next day. I am doing a PhD at 51 and the loss of daily fatigue and genuine improvement in clarity and positive thinking is defiantly a side effect of the pills. Its not a hyped up feeling but just a general feeling of well being and clarity. Similar to eating a good water Mellon with its zinc and trace elements, that give a pleasant positive feeling, but it lasts all day.
Also researching this for the best brand, stick to host defense as there is a great deal of other brands using foreign suppliers or suppliers that don't openly state their source. So you may be getting mushrooms grown in highly polluted environments/country's.
