Slenderize Review - Does This Diet Pill Actually Work? Are fad ingredients and customer complaints deal breakers?

Editor's Review: 3.1 / 5.0
Slenderize Review

The results of my research into Slenderize were somewhat surprising. Here at DietSpotlight, we conducted an in-depth review, closely examining the possible side effects, all ingredients, customer service and scientific studies. Plus we read dozens of dieter comments and user claims we found online. We then summarized the information to give you the important facts you need.

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

What is Slenderize?

To get things going, Slenderize is a diet product that aims to boost metabolism, help you burn off more calories, increase energy levels and suppress appetite. It is directed to be taken once or twice each day, along with meals. A sensible diet and exercise plan are recommended. The ingredients used in this product are chromium, caffeine, hoodia gordonii, glucomannan, green tea, theobromine, guarana, cha de bugre, maca root, caralluma fimbriata, l-theanine, banaba leaf, pomegranate fruit and guggul extract.

It is unclear when Slenderize was first released, but it is available on dealer websites like Amazon. Furthermore, this diet product does contain some natural ingredients and it’s fine for both women and men alike, but read on…

Fad Diet Ingredients – “Something to Think About?”

First off, it is important to us that Slenderize ingredients we tested and proven to aid with weight-loss. ”The formula contains Hoodia Gordonii, which is a natural cactus plant extract commonly used in many weight-loss supplements available today. However, there is no solid clinical research that supports, so it may be considered a fad,” says our Research Editor.

One customer stated, “Does not work as claimed! I saw no weight-loss at all.”

Another dieter offered, “Not effective for fat burning or suppressing hunger. Felt a slight energy boost, but that’s it.”

Numerous Customer Complaints!

There are quite a few user complaints posted online for Slenderize. One customer said, “Made me seriously nauseous. Had a bad stomachache for hours!”

“This stuff is awful! Gave me a headache and abdominal pains that lasted all day,”another user commented.

Our research has revealed that if there is one particular aspect of a weight-loss product or diet program that is especially problematic (fad diet ingredients, too many customer complaints, high price) the actual chances of long-term results are not good. In other words, if Slenderize does lead customers who’re unhappy, this could be a major issue.

Any Real Science?

Here at DietSpotlight, we prefer to see actual clinical studies that support the weight-loss product we’re reviewing. As for this one, we found research into green tea and the caffeine supplied by guarana. But, there’s nothing that says this formula will work better than the thousand others with the same general formula. And, some of the ingredients have NO backing at all.

The Bottom Line – Does Slenderize Work?

So, should you buy Slenderize? Well, we like that it contains natural formula and it’s easy to find online. Then again, we have some reservations about this diet product because it’s not backed by actual science. Furthermore, we’re concerned about its fad supplement ingredients and the numerous customer complaints posted online.

If you’d like to drop more weight, then we suggest you go with a product that is supported by clinical research, does not use fad ingredients and is backed by plenty of positive customer reviews.

Among the best products we’ve seen in 2016 is one called Leptigen. Its formula is a unique blend of four ingredients, which have been proven in published clinical research to help increase fat loss and kick-start metabolism. We can’t find any complaints of harmful side effects and user comments posted online indicate people are seeing great results.

The makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is very encouraging.

Slenderizer is a weight loss supplement created by Strictly Health, a company based in Delaware that manufactures various types of health and nutrition products that cover areas such as beauty, weight loss, skin conditions, immunity boosters, and other similar products. Slenderizer is one of twelve different products available in their weight loss line.

Slenderizer is a lipotropic fat burner, which means that it helps your body metabolize fat better than it can do naturally. Slenderizer uses a mixed blend of different ingredients that are all supposed to work together to work better than a single lipotropic fat burner would. The official website claims that by taking Slenderizer you will lose weight, as well as become less susceptible to various diseases and conditions such as cancer, diabetes, and lymphatic problems.

List of Ingredients

Slenderizer contains: Chromium (as Chromium Picolinate), Phelodendron amurense extract (standardized for 1% Berberine), Magnolia (Magnolia officinalis) 4:1 extract, Calcium Pyruvate, Citrus aurantium (standardized for 10% Synephrine), Epimedium (Epimedium koreanum) 6:1 water extract, Beta Sitosterol, Inositol Hexaphosphate, DL-Methionine, Alpha-lipoic acid, Phosphatidyiserine.

Other Ingredients: Gelatin, Microcrystalline Cellulose, and Magnesium Stearate.

Product Features

Slenderizer makes a lot of claims in the areas of overall health, but the product doesn't give very much information on its actual ability to help you lose weight. It does go into detail about how lipotropics work and how they can help lose weight, which is fairly interesting, but it's also fairly technical and not very informative.

Slenderizer does contain a powerful stimulant in the form of Syneprine, which is a safer alternative to the once popular, semi-banned stimulant Ephedrine. This will boost your energy but might also cause some feelings of nervousness or jitters. Slenderizer also contains Chromium which helps your body regulate blood sugar levels and may decrease your need to snack on certain foods that are high in carbohydrates.

  • Slenderizer contains all-natural ingredients.
  • Some ingredients in Slenderizer may be beneficial for the liver.


  • There doesn't seem to be an appetite suppressant present in Slenderizer.
  • The official website doesn't have any testimonials or clinical trial results posted.
  • There is no free trial or sample size available for this product.


Slenderizer does have ingredients found in many well-known diet products, such as synephrine, but many of the other ingredients may not be very effective as weight loss agents. The inclusion of synephrine is a double-edged sword for many people. It will give you energy, but in some people the jittery feeling that accompanies that energy won't be worth it. We would have liked to see an appetite suppressant in the ingredients as well so it would have been more of a complete weight loss product. We recommend finding something that does combine an appetite suppressant with a powerful fat burner in one convenient tablet instead.
