Some considerations for people taking passion flower include:
Since the manufacturing of supplements (such as passion flower) is not closely regulated, it is important to choose a trustworthy manufacturer for passion flower supplements. It is a good idea to look for the "USP" symbol, since this means that the supplement has been tested and contains the right ingredients in the right amounts.
If you have any chronic health problems or take any prescription medications, it is probably a good idea to check with your healthcare provider before taking passion flower.
If you are unsure about anything related to your dosage or passion flower dosing in general, please talk with your healthcare provider.
