LONGECITY

The researchers initially experimented with fruit flies. They mixed a mycelium extract of the mycelium from Lion's Mane through the growth medium of the flies, and saw that this made them live 32 percent longer.

 

 

 In a second series of experiments, the researchers gave Lion's Mane to mice for 13 weeks. To SAMP8 mice, to be precise, a strain of lab mouse which ages faster than other types of lab mouse.If the mice in the experimental groups had been adult humans, they would have received 750, 1500 or 3000 milligrams of Lion's Mane extract daily. The mice that did not receive extracts lived for 13-14 months. The mice that received a low, medium or high dose of Lion's Mane extract daily lived an average of 15, 16 or 16 months respectively. So we are talking about an increase in the average lifespan of up to 23 percent.

Interesting, but:

"may prolong life. This is suggested by animal studies published by the research department of Taiwanese manufacturer".

You have a valid point.  The worry here is that there is always going to be some conflict of interest.  With that said the Materials and methods look look pretty standard. https://journals.plo....0217226#sec002
