Why do people use Lion's Mane?

People who self-experiment with Lion's Mane often state they use it to improve their:

  • Memory
  • Problem solving
  • Mood

Let's see what the scientific evidence on the effectiveness of Lion's Mane for these purposes says.

Lion's Mane for cognitive performance enhancement

Compared with a placebo, 3g Lion's Mane improved cognition after 8, 12, and 16 weeks of daily treatment in patients with mild cognitive impairment. [1] The beneficial effects were almost gone 4 weeks after the discontinuation of Lion's Mane use. Because this study was not conducted in healthy humans, its findings should not be taken as strong evidence for the efficacy of Lion's Mane as a nootropic for cognitive enhancement in healthy humans.

These findings have also been backed up by results from several animal studies. [2][3]

The evidence on the effects of Lion's Mane on cognition in people with cognitive impairment suggests it improves cognitive performance. There's no scientific data available on its cognitive effects in healthy humans.
