I trust the quality of NOW brand & was even recommended by my Naturopath for its quality. I take this passionflower to aid with sleep as I have insomnia, combined with other sleep herbs it helps to get to sleep & get back to sleep if I wake up during the night. The capsules are an easy size to swallow and no real unpleasant smell or taste. I usually take up to 1000mg combined with other herbs but my insomnia is pretty bad, others may not need so much.
For the money, this is the best quality Passion Flower I could find and iHerb's price coupled with free and incredibly fast shipping makes the offer unbeatable. I get irritated easily. A capsule of this extract twice daily keeps me much, much calmer. Recommended.
This supplement caused severe heart palpitations. However, this sometimes happens when I try new product. Finding the right supplements that work for me is a trial and error. Although I had to discard this product, by trying different ones I actually found some good ones along the way and I effectively manage my insomnia. Thanks to other supplements that worked I have had no sleepless night in 3 months. I was hoping to add Passionflower to the stack, but will stick to melissa, chamomile and hawthorn. But don't give up, this product might be good for you. Good luck to all insomniacs out there.
