Passionfruit is the fruit of the Passiflora edulis vine. People eat it fresh or take it as a juice, powder, or extract. Do not confuse it with passionflower (Passiflora incarnata), a different plant used in traditional sleep and stress remedies.
Most people use passionfruit for its vitamin C, fiber, and antioxidant content. It works best as a food or general nutritional supplement. Solid evidence does not support using it for sleep, stress, or other specific health targets.
You can find it as a juice, powder, or extract. Doses vary widely between products, so follow the label on whatever form you choose. Take it with or without food at any time of day.
An allergy is possible, especially for anyone with latex fruit syndrome. Avoid it if you are allergic to passionfruit or related fruits.
