How to Take

Recommended dosage, active amounts, other details

An ethanolic extract of 125mg/kg has been used in rats with efficacy, which translates to an estimated human dosage of:

  • 1,400mg for a 150lb person

  • 1,800mg for a 200lb person

  • 2,300mg for a 250lb person

These are estimated human doses based on rat studies, and it is uncertain if they are the optimal dosage or not.
