Diet products either work or they don’t. Period. Let’s find out which one Phenylethylamine is. We looked closely at ingredients, side effects, clinical research, and customer service. Then we sorted through hundreds of user comments to see what people actually thought. We condensed and summarized everything to give you the bottom line.

What is Phenylethylamine?

Firstly, Phenylethylamine is an ingredient used in dietary supplements. It supposedly improves focus and concentration. The dosage and suggested use vary by product.

Several companies make this supplement and it has been on the market for a while. It’s sold through various outlets and health food stores. We like that it is naturally found in the body, and made from an amino acid, but read on…

Ineffectiveness – “Not For Weight-Loss”

The first issue is many reports of ineffectiveness of Phenylethylamine. This isn’t really intended for weight-loss, but could help with cravings as a secondary issue. “Since this is an amino acid that affects the brain, it is best used for focus and energy. As such, it’s not going to have the same effects as a fat burner or appetite suppressant,” said our Research Editor.

“It may be amazing stuff, it is not what my body needs personally. I didn’t notice a difference on it. Doesn’t mean it can’t work for some though,” said one user.

“I bought this along with the other supplements they recommended (Hordenine and PEA) and they just don’t do what they say. I even tried them at some of the dosages recommended on some of the sites and to me they are not worth the cost,” said another.

Not everyone claims the supplement is ineffective.

“It works wonderful for those that want to loose weight. It makes your brain not to crave sweets and I am never hungry specially for junk food,” said one dieter.

“I have been using this product for a couple weeks and I am totally satisfied with the product. My family is in awe at the change it has brought about in me,” said another.

Phenylethylamine Side Effects – “Watch Out!”

According to Phenylethylamine reviews, side effects are a concern. Several users reported feeling jittery while using this supplement.

“Tried taking these as recommended for a few weeks and it made me feel like I’d had too much caffeine. Gave me the wrong type of energy, almost jittery. I’ll switch back to my morning cup of coffee, which was working much better,” said a customer.

“Anxiety in a bottle for me… Didn’t notice it at first but after a few days I felt like I’d drank a river of coffee,” according to one review.

There were many who used it without side effects.

“No side effects and . I’m really GRATEFUL that I found something affordable and more natural than an RX,” said a reviewer.

“I have been using this for awhile now and find it helps to calm my nerves and to help me handle day-to-day stressors. No side-effects — I do love it.,” said another.

Our years of experience have shown us that if something doesn’t work or causes side effects, people are going to keep looking until they find something that gets the job done without making them feel awful.

The Science – “Clinically Tested, But…”

This is a clinically tested ingredient, but it’s tested for attention, memory, and focus. It’s not a fat burner or an appetite suppressant. You may see it included in weight-loss formulas, but alone it’s not likely to help you shed pounds.

At DietSpotlight, we want to see science that proves a supplement safe and effective for weight-loss before we can recommend any product.

The Bottom Line – Does Phenylethylamine Work?

Is it time to clear the shelves of Phenylethylamine?

If you’re ready to lose weight, we suggest using a supplement that contains clinically tested safe and effective ingredients specifically designed to help boost the metabolism to help you lose more compared to diet and exercise alone. It shouldn’t cause side effects and should be supported by positive customer reviews to show effectiveness.

Among the best products we’ve seen this year is one called Leptigen. Made with four key ingredients all shown in studies to support a healthy metabolism, we weren’t able to locate any negative comments or mentions of side effects. This tells us users are getting solid results.

Also, the makers of Leptigen are currently running a Special Trial Offer so people can try it for themselves. We love to see this level of confidence in a product.
