Passiflora Extract Benefits

Passiflora Extract is taken as a supplement to improve sleep. Passiflora Extract improves sleep through the acute reduction in symptoms of insomnia and anxiety.

Scientists believe passionflower works by increasing levels of a chemical called gamma aminobutyric acid (GABA) in the brain. GABA counters the activity of neurotransmitters that cause excitement, making you feel more relaxed.

Evidence for the Effectiveness of Passiflora Extract

Passiflora extract has a long history of use in traditional medicine. In North America it is commonly consumed as a tea ("Te de Pasiflora") and used as a sedative. In Europe Passiflora is used in the treatment of insomnia and anxiety (1). More recently, academic researchers have started to study its effectiveness.

In one double-blind, placebo-controlled study (2), 41 participants (18–35 years) drank a cup of tea made with Passiflora incarnata and filled out a sleep diary for seven days. 10 of these participants also underwent overnight polysomnography during the final night of the study. 

Based on the participants' sleep diaries, sleep quality was significantly better in the tea-drinking group compared to the placebo group (t = 2.70, P < 0.01). This study shows that Passiflora incarnata L. has a potential effect on quality of sleep (2) .

Is Passiflora Extract Safe?

Passion flower is generally recognized as a safe substance (GRAS) by the FDA (3), however due to proposed mechanism of action (increased GABA concentrations in the brain) interactions with sedatives (4), anticoagulants, and monoamine oxidase inhibitors are possible.

A doctor or other healthcare professional should be consulted before taking any new supplements or medications. They can help you understand better any potential interactions and recommend appropriate changes.

Passiflora Caerula vs. Passiflora Incarnata, What’s the difference?

The common name for Passiflora Caerula is “Blue Passionflower'' while Passiflora Incarnata is commonly known as “Purple Passionflower”. To add to the confusion, Passiflora Incarnata is often referred to as simply “Passionflower”. Despite the similarity in their names these two plants are distinct and should not be confused with one another.

If you are looking for a beautiful ornamental plant that acts as a wall-climber or groundcover then Passiflora Caerula has you covered.

If you’re looking to enhance your sleep quality or reduce anxiety (5) then you should consider a supplement with Passiflora Incarnata extract.

Te de Pasifora

Passiflora Tea is a popular method of consumption of passionflower. You may find this tea labeled as "Te de Pasiflora" in your local grocery store. Passionflower tea is recommended for insomnia and restlessness. Te de Pasiflora has a mild taste and pairs well with other herbal teas such as chamomile and valerian root. Passionflower extract (Passiflora Extract) is a more concentrated form of the same active ingredients in found in Passionflower tea. 

How much Passiflora Extract is in Sleep Boost?

Sleep Boost contains 20mg of Passiflora extract per serving combined with 2mg of melatonin. Both of these ingredients are fast-acting and promote restful sleep. Passaflora is naturally calming and melatonin helps to regulate your body’s circadian rhythm to promote a healthy sleep schedule.
