From the Research

The recommended dose of Lion's Mane mushroom (Hericium erinaceus) is 1.8 g daily, as supported by the most recent and highest quality study 1. This dose has been shown to improve cognitive function, speed of performance, and reduce subjective stress in healthy, young adults.

  • The study published in Nutrients in 2023 1 investigated the acute and chronic effects of Lion's Mane mushroom supplementation on cognitive function, stress, and mood in young adults.
  • The results of this study suggest that Lion's Mane mushroom may improve speed of performance and reduce subjective stress in healthy, young adults.
  • Another study published in Nutrients in 2023 2 found that a single dose of 1 g Nordic-grown Lion's Mane significantly improved reaction time during N-Back and improved Go stimulus reaction time in Go/No-go.
  • While other studies have investigated the effects of Lion's Mane mushroom on cognitive function and neurological health, the study by 1 provides the most recent and highest quality evidence for the recommended dose.
  • It is essential to note that Lion's Mane supplements can be taken with food to minimize potential digestive discomfort and should be taken consistently for at least 4-8 weeks to evaluate effectiveness.
  • As with any supplement, it is crucial to consult with a healthcare provider before starting Lion's Mane supplementation, especially if you are taking medications or have existing health conditions.
