Erinacine-A-containing Hericium mycelial extract

Species, preparation, dose and limitations are retained on linked claims.

2 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it acts on

  1. In rats, oral mycelial extract equivalent to 50 mg/kg erinacine A gave 24.39% estimated absolute bioavailability; erinacine A was detected in brain at 1 hour and peaked at 8 hours.
