In their own words
“I’ve been using Nigella Sativa and Red Reishi Ultimate for some DHT inhibition and haven’t seen any changes or growth, if anything I might’ve lost more hair/thinned out.”
“Red Reishi Ultra can only be taken before sleep. If take it in the morning, it causes me to be tired/sleepy. Really helps with sleep.”
“What finally worked for me was a combination of magnesium and red reishi... now I fall asleep much faster, wake up only once if even that, and wake up energized and refreshed”
“I tried: ...Red Reishi...they didn't help. Some would give me a little bit of relief from anxiety, others might lift the brain fog for a few days, but none of the ones I tried did anything meaningful”
“I made the mistake of taking red reishi and lions mane at the same time in a two week period I went from pretty normal to calling suicide hotlines.”
