PheniTropic by Biotics Research promotes a calm mood and is used to ease anxiety, reduce stress, and improve cases of sleep impairment. It also possesses nootropic properties that have shown to increase cognitive functions and benefit memory processes. It is one of the most effective amino acids available to support emotional and neurological health, and is produced by Biotics Research – a corporation dedicated to staying on the forefront of nutritional innovation.

What are the benefits of PheniTropic?

  • Decreased stress
  • Reduced anxiety
  • Positive mood change
  • Improved energy levels
  • Improved sleep patterns

What is the key ingredient in PheniTropic?

The key ingredient is beta-phenyl gamma-aminobutyric acid, or “phenibut.” Phenibut is a derivative of a natural neurotransmitter known as GABA. GABA is a primary inhibitory neurotransmitter similar to serotonin, dopamine, and norepinephrine. GABA is associated with feelings of happiness and exhilaration, and is also linked to lessening anxiety.

How does PheniTropic work?

Neurotransmitters like GABA are essential components in regulating emotions, mood, energy levels, and sleep. However, neurotransmitter balance can be easily disrupted by factors like stress, immunity, diet, and genetics. When GABA levels are low, one may feel anxious, irritable, hyperactive, or have difficulty sleeping. Phenibut acts as a GABA receptor agonist, meaning that it can cause a significant release of GABA in the brain when taken. Phenibut also has the ability to cross the blood-brain barrier, so the effects of phenibut are noticeable soon after taking this supplement. Clinical studies have found that Biotics Research PheniTropic can regulate GABA levels within an hour of administration.

Is PheniTropic safe for me to use?

Due to the natural derivation of phenibut from GABA, it appears there are no negative side effects from taking PheniTropic as directed. However, each individual can react differently to the supplement. It is always best to consult with a healthcare professional before taking this supplement. This product should not be taken in conjunction with alcohol, sedatives, MAOIs, sleep aids, or anxiety medications.

Great for sleep and I also occasionally take it during the day to decrease anxiety. It doesn't seem to make me sleepy during the day, just more calm and focused.

My herbalist recommended this product after I tried several others that weren't helping at all. Phenitropic has been a huge help to me since I developed problems falling asleep due to extreme stress. I'm so glad that I finally found something that helps!

Consistently works

Review by Wedon'tcoast (Posted on 3/28/19)

My husband has been taking PheniTropic for a few years now and it has made a world of difference in his ability to sleep. For many years, he would wake up through the night and his mind would spin and he couldn't fall back asleep. This enables him to sleep better and if he does wake up he is able to stay relaxed and fall back to sleep quickly.

Love It

I've been using PheniTropic for about a year. I have a very demanding job and constantly on the go. When I would try to sleep at night I had a lot of rambling dreams about being at work. I would get up in the morning feeling so drained. Tried this product at the advise of my doctor and I feel so refreshed in the morning.

Great product for insomnia due to anxiety

Review by Deborah (Posted on 2/12/19)

Overall Rating

This product has been a lifesaver for me the past 4 years. Between anxiety keeping me awake and hot flashes waking me up, it has been a decade or 2 of sleep deprivation. Phenitropic has helped me tremendously with getting better sleep. I've found it's best taken several hours after eating. If you over eat and then use PheniTropic it doesn't always work because of competition for the receptors needed. Great product. Highly recommend!

I sleep great now!

PheniTropic was recommended to me by a naturopath doctor and has really helped me with sleep issues. When I take it about an hour before bedtime, I am able to fall asleep and stay asleep so much better than I did before.

Really helps with sleep when you deal with anxiety. I don't take it on a regular basis; only when I'm having a lot of anxiety. I have found I have weird dreams if I take it when I'm not anxious.

Best thing I've tried to make my sleep more restful

Review by Easytimes (Posted on 10/12/18)

Overall Rating

My nutritional doctor has been trying to help resolve my insomnia problem, and the closest thing I've used to resembling an answer has been Phenitropic. Nothing actually makes every night a 6+ hours of sleep night, but I can say that I don't have so many sub-4 hour nights as I did before taking Phenitropic.

I can blame some of my problems on hurricanes Florence and Michael, which had our generator singing its harshly electrifying song through many nights. Hopefully a little normalcy will help, as well.

A Natural Product to Help Me Sleep

Review by ValfromCali (Posted on 10/12/18)

Overall Rating

PheniTropic was recommended to me by my nutritionist because I was having trouble sleeping. She told me to take two each night but when I woke up, I still felt groggy so I cut it down to one per night. I probably should have taken them earlier in the evening; however, I was afraid that I would fall asleep too early. Taking one nightly helps me fall asleep and stay asleep naturally. This product also helps me stay "mellow" through-out the day as it is good for anxiety as well.

Great nights sleep!

Must have for great sleep

Review by Beth (Posted on 10/12/18)

Overall Rating

I first learned of PheniTropic from a doctor at a conference in 2015. I have used it ever since for great sleep, improved energy and mood, and an added memory boost. Recently I had a brief period when it was not available and was disappointed to see my sleep quality decline. Unlike other sleep aids, I have not seen it diminish at all in effectiveness over the three years I have been using it and am so glad to see that it is available again.

Not potent enough

Great sleeping aid

Review by John (Posted on 6/8/17)

Overall Rating

I like Phenitropic because it doesn’t make me feel groggy or lose its effect after taking it for a long time, a problem I’ve encountered with other sleep aids. I feel restful and alert every morning after taking this. My chiropractor told me it can even be taken during the day to help with stress and anxiety. I couldn’t image using anything but Phenitropic… please try this product if you have sleep issues or stress!
