    Overview

    Dosage information

    The most effective dose and frequency for passionflower have yet to be established. Manufacturers frequently do not specify the purity and concentration of passionflower supplements, contributing to uncertainty regarding recommended strength, frequency, and dosing. There are currently no generally accepted dosage guidelines for passionflower. However, a range of dosing has been used in different clinical studies and may be used for reference. Dosing for capsules and tablets ranges from 500–1200 mg per day.[1][2][3] For liquid extracts, dosages typically range from 30–60 drops diluted in water per day.[4][5][6]

    Additionally, one study using passionflower in the form of tea used a daily dosage of 2 grams of dried passionflower leaves steeped in hot water.[3] However, it's worth noting that the author acknowledged this as a relatively low dosage, and to achieve more significant benefits, the tea should have been consumed three times a day. This was not feasible due to the risk of daytime sedation.
