Appethyl Review - Does This Dietary Supplement Work? Are cost and lack of efficacy deal breakers?

Editor's Review: 3.5 / 5.0
Appethyl Review

Appethyl is a dietary supplement that has really started making a name for itself, so we did one of our in-depth reviews to include side effects, ingredients, customer service and clinical research. Hundreds of comments were taken to heart. Then, we refined and summarized to give you the bottom line.

EDITOR'S TIP: Substitute Appethyl with a proven fat burner such as Leptigen for better results.

What You Need to Know

Firstly, Appethyl isn’t a meal replacement plan, but it is designed specifically to suppress appetite. The product is supposed to support weight-loss by utilizing thylakoids, small organelles found inside green plant cells that can slow down the digestion process. It is easy to take; all you need to do is mix one scoop of the powder with water and take it before a meal high in fat. Only one serving is necessary per day. There is also a capsule option, which works as a nice alternative to the grainy powder.

Appethyl, which was introduced in 2013, won the award for “Best New Functional Ingredient” at the 2013 NutraCon conference, and it is now available in health stores, on its official website, and online on Amazon and similar retailers. We like the natural ingredient (thylakoids), and it seems like a fairly easy product to take, but read on…

Price – “Too High?”

The first issue we found in user reviews were reports of a big price tag for Appethyl. “You may see some appetite reduction if you take the supplement as directed,” said our Research Editor, “But, it costs almost $60.00 for a month’s supply.”

“Very expensive product for the results I got,” one user said.

Efficacy– Another Concern

As with some dietary supplements, the promised results don’t always come true for everybody. Upon sampling user reviews, we started noticing a theme. “I’ve been taking Appethyl faithfully as directed. My appetite has not changed, nor has the fat started shrinking as it promises.”

“I know everyone is different, but I didn’t have that much luck,” said another. After further reading, it seems these negative reactions don’t stand alone..

Although Appethyl shows a lot of promise, even one drawback to the product can hurt its long-term success. In this case, the pricing demands a significant commitment on the part of the user. If the cost sits too high for most people to commit to for very long, the chances of it helping them keep weight off aren’t great.

The Science–Is It Solid?

The whole concept of thylakoids is rooted in science, and it appears that the effect on human appetites has been studied. Scientific research is not an issue here, but the relationship of the supplement to weight-loss might be. Appetite suppression is only one small part of the equation, and someone spending money on Appethyl may need more than that.

The Bottom Line – Does Appethyl Work?

Appethyl is certainly an exciting new product, and we are looking forward to seeing how it’s used in the future. For now, though, the product only focuses on appetite suppression, which is a relatively small slice of the pie. Furthermore, Appethyl is quite expensive and doesn’t work for everyone. These are more than enough to leave us with some reservations about recommending it.

We recommend two things in a supplement if you still need to shed some pounds – a good value for your money and a strong formula.

Among the best products we’ve seen in 2016 is one called Leptigen. Its proprietary blend of four ingredients may help boost metabolism and help you burn fat, based on a multitude of customer reviews.

Check out the Special Trial Offer; it’s always reassuring when a company stands behind their product.

Appethyl is an ingredient most dieters will not be familiar with because it has not yet hit the market. Green Medical AB is the company behind the ground-breaking spinach extract. The extract was honored to be named one of the finalists for the NutraCon NutrAward as of February 2013. Green Medical Abs official website explains the extract as a derivative of spinach that decreases appetite, reduce waist size and improve glucose and cholesterol levels. There is mention of clinical studies, but no links to such studies. We were able to find some studies on the active portion of Appethyl and appetite.

List of Ingredients

  • Thylakoids

Product Features

Thylakoids are nothing new. When we researched the spinach derivative we found studies from the 1970s, but current studies are also available. According to one study completed in 2009, thylakoids added to one high-fat meal sparked changes in the body that helped ease hunger after the meal. The changes took effect between two and six hours after the meal was consumed. Insulin levels were also affected in a positive manner – reducing insulin reaction to the meal. We found additional, similar studies from 2007. For a relatively unknown weight loss ingredient, thylakoids have a strong clinical history. We are unsure why this ingredient has not been promoted as an appetite suppressant to date, but Appethyl is poised to break the market and make lots of money as the primary source of this (soon-to-be) patented ingredient.

  • Clinically proven to suppress appetite.
  • Works hours after consumption.
  • Derived from all-natural spinach.
  • Patents pending.
  • Fills a gap in the weight loss market.


  • Not currently used in any weight loss supplements as of February 2013.
  • Does not address increasing metabolism.
  • No large-scale clinical studies have been completed.


Appethyl is an amazing ingredient that could be the answer to weight loss issues for millions of people. Hormonal changes in the brain sparked by Appethyl suppress appetite. The ingredient works as a prebiotic and helps maintain healthy insulin levels. When this ingredient hits the weight loss market, we can expect a long list of new supplements touting the weight loss benefits of Appethyl, but controlling hunger is just one aspect of supplemental weight loss. The best formulas will contain other clinically proven ingredients like caffeine and green tea. We’ll have to wait and see just how the Appethyl story ends or, in this case, begins.

    GNC has appidex. They claim that it has appethyl in it. I read the first mag article. I’m going to make the spinach smoothie and add the appidex and yogurt. I just found the hydroxycut appetite control at Walgreens. It is a powder. I am on my way to pick it up. My birthday is in March and I want to have dropped 2 dress sizes. Of course I’ll work out, eat right and yada-yada-yada but for right now this is my motivation!
