What is inside Fenotrex?


Melatonin is a hormone that is secreted by the pineal gland. It’s used to help conditions such as insomnia, sleep disorders, and other sleep problems. Melatonin helps in regulating the body’s internal clock. It maintains the cycles of sleep and wakefulness.

Valerian root

Valerian root has a sedative effect and has a long history of use to promote relaxation and sleep. Studies have found it helps improve the speed at which you fall asleep, depth of sleep (achieving deep sleep 36 percent faster7), and overall quality of sleep.

Hops flower

Hops are the seed cones, or strobiles, of the hop plant, which has its roots in Europe and western Asia. Hops demonstrate modest potential in challenging insomnia and other sleep disorders.

Chamomile flower

One of the active compounds in the chamomile plant is apigenin; studies have found that this compound reduced locomotor activity. Flavonoids, mucilages and coumarins are also present in chamomile and may have a calming effect on the body, allowing for a more restful sleep.

Passion flower

Passionflower, specifically Passiflora incarnata, has been in use as an herbal sedative and sleep aid for a long time but there have been few clinical trials conducted to verify its effectiveness. The few studies performed highlight its likely capacity to mitigate anxiety and improve sleep quality.


American Skullcap (Scutellaria lateriflora) is well known for its ability to induce sleep and prevent anxiety, nervousness, twitches and convulsions. Skullcap is an effective relaxant which has been used for over 200 years among native Americans in particular.

Valerian Root And Hops Flower Some research suggests that taking a combination of hops extract plus valerian extract at bedtime helps some people fall asleep faster. It appears to take 28 days of treatment to see these benefits.
Chamomile Flower One study found that people who consumed 270 mg of chamomile extract twice daily for 4 weeks had 1/3 less night time awakening and fell asleep 15 minutes faster than those who did not consume the extract.
Gamma-aminobutyric acid (GABA) In a small study participants taking capsules of GABA an hour before going to bed fell asleep faster than those taking a placebo. They also reported improved sleep quality four weeks after starting treatment.

"I took Fenotrex and ended up getting the best night's sleep!"

"I've been dealing with insomnia for most of my adult life. I’ve tried using a bunch of different over the counter stuff like melatonin, and I even did the prescription thing for a little while, but they either didn't work or made me feel sleepy and weak the next day. I had a friend that sent me a bottle of Fenotrex after listening to me complain, and honestly I didn't think it would work either. I figured I had nothing to lose though, so I took the stuff and ended up getting the best night's sleep that I could remember. I'm a lady of a certain age, so I naturally have to get up in the middle of the night to go to the bathroom occasionally, but I never have any issues getting back to sleep. This stuff has totally changed my outlook – I'm starting to see what I was missing all these years."*

“So far it's been way better than the prescription stuff.”

"I do a lot of traveling for my job, and I have some issues getting to sleep when I'm in hotels or other strange environments. It got so bad that I started using prescription sleep aids to help, but I hated how I felt the next day and gave those up pretty quickly. As I weaned myself of the drugs, I went looking for a natural aid that could maybe help me fall asleep, which is how I found Fenotrex. I used it as they instructed, fell asleep that first night without any issues, and it's been working for me since. I'm also a pretty light sleeper and I wake up easily if there's any noise outside, but with Fenotrex I'm able to just get right back to bed instead of staying up for hours like I used to. So far it's been way better than the prescription stuff that I was taking – I wake up refreshed instead of groggy, which to me is the whole point of a product like this. It also seems like a much better option health-wise to stay away from the prescription stuff, so I feel better about taking Fenotrex long-term. I’d certainly suggest that anyone else that’s been having sleep issues and is looking for an effective non-prescription option."*

“Fenotrex has been huge for me this last month!”

"I just finished my last year of law school and I'm getting ready for the bar now. I've had some long nights trying to balance both work and preparing, and so my opportunities to get good sleep are rare. I needed something that could help me get to sleep fast, get deep, restful sleep, and also not feel drowsy in the morning. Fenotrex has been huge for me this last month, helping me get to sleep when I need to, and then wake up recharged and ready to get right back at it the next day. The bottle recommends two caps per use, but I tend to only need one unless I'm really tense or had too much coffee – which definitely happens during study time. I'm so glad that I was able to find a product that met my requirements when I did. My test date is less than a week away now, but I'm feeling good about it – and I'll probably keep using it even after I pass!*
