Phenaprin Ingredients Review

Phenylethylamine HCL (PEA) PEA is a natural chemical compound that is responsible for the release of dopamine and norepinephrine in the brain. These neurotransmitters are responsible for regulating mood, appetite, and energy levels.

Phenaprin contains L-Phenylalanin which can help control your appetite so that food no longer controls you! Many struggle to resist when a co-worker drops a dozen fresh donuts on their desk. You want to pick one up. Phenaprin can give you that self-control you need to say no to unhealthy foods.

L-Phenylalanine is an essential amino acid that acts as an appetite suppressant by releasing an intestinal hormone called cholecystokinin which signals the brain to feel satiated after eating.

Side Effects of Phenaprin

Phenaprin is a weight-loss supplement that is marketed to help people lose weight and increase energy levels. However, it is important to note that Phenaprin contains synephrine, a compound that has been linked to serious health risks.

Synephrine is a stimulant that is similar in structure to ephedrine, a compound that has been banned in the United States due to many reported heart attacks and strokes.

Synephrine (bitter orange extract) is not a dangerous component. However, when combined with Caffeine it acts like Ephedra!

While synephrine is not as potent as ephedrine, it can still cause serious health problems, especially when taken in large doses or for extended periods. Studies have shown that synephrine can increase blood pressure and heart rate, which can put individuals at risk for heart attack.

Caffeine also can cause headache and jitters. It’s not suitable if you are sensitive to caffeine.

Phenaprin also contains L-Taurine & L-Carnitine as supportive ingredients. Additionally, it also contains few essential miners and vitamins

Phenaprin Customers Review

I used this product for weight loss. I used the regular Phenaprin for the first month. Took one in the morning and one before lunch. Didn’t notice anything. I haven’t lost any weight. Have actually gained a couple pounds. So the next bottle I ordered with my 20% discount, I got the XR kind instead. I think they have been decreasing my appetite somewhat. I haven’t weighed myself since I started the XR kind, I want to give it a good month or so to see any progress.

I just got this today & took one pill. So I can’t speak to its efficacy regarding appetite/weight loss yet. I will update my review in about a month for that. What I can say is my stomach started cramping within 20 mins of taking it & I got pretty nauseous. made me so drowsy I had to take a nap. Which is very much opposite of what it’s supposed to do. Hopefully these effects go away with continued use. I’m really glad I started on the weekend & not a day I had to work. That would’ve been a problem!
