Slim Science Review - Does This Appetite Suppressant Work? Are lack of results and harmful side effects deal breakers?

By Summer Banks on Sep 03, 2016
Slim Science Review

I paused before I hit the “publish” button on this one, because my conclusion was a bit of a shocker. Slim Science is relatively new to the weight-loss industry, so we decided to put it to the test with one of our in-depth product reviews. We looked at the ingredients, side effects, research and customer-service quality. We also read experiences on multiple websites. We summarized and condensed to give you the bottom line.


What You Need to Know

First off, Slim Science uses plenty of powerful ingredients including L-carnitine, caffeine, thiamin, green tea Extract, and ginseng root. Their products can be purchased in capsule form, which are taken daily to help suppress appetite and improve energy levels. There’s no trouble taking this portable supplement with you.

Slim Science has only been around for a few years, but they’re already making waves in the industry for both good and bad reasons. Their products include an affordable diet supplement with solid ingredients, their website provides support and they offer a money back guarantee, but read on…

Lack of Results – “Placebo Effect?”

Our first issue with Slim Science ingredients is the lack of results. Most customers that saw results attributed it to the fact that they were filling up on water, rather than the supplement itself. “When drinking the recommended amount with Slim Science, it will suppress your appetite,” said our Research Editor. “But that’s more because of the volume than the effectiveness.”

“No different than a multivitamin. For those that do see results, this is the placebo effect at its finest,” said one user.

“I took this for the first month and saw no results, it doesn’t do anything for my appetite, and I didn’t lose any weight,” explains a user.

Harmful Side Effects – “Are They Worrisome?”

Most of the reviews online were highly critical of Slim Science and one repeat concern was the numerous side effects that seem to stem from taking it. “Slim Science uses the same ingredient, Garcinia Cambogia, that has been found to cause liver problems,” said one user.

“I took this product and wasn’t feeling like myself for 4 days. It caused numerous side effects that suddenly stopped when I stopped taking Slim Science,” offers another.

It seems like many people had similar concerns, especially when combining Slim Science with other medications. “Do not take this if you take drugs for diabetes or if you’re on blood thinners. It can cause dangerous side effects when interacting with other drugs” said one customer.

Throughout our time writing diet and supplement reviews, our research has shown that weight-loss programs that have aspects that are especially troublesome (lack of results, high cost, taste, side effects, painful workout, etc.) are less likely to lead to long-term results. If Slim Science really does cause these adverse reactions, it may not be worth a try.

The Science – “Clinical Evidence?”

With a name like Slim Science, we assumed there would be plenty of evidence supporting their promises, but we were immediately disappointed. Not only do their products lack published research, but there’s actually some proving that one of their ingredients is potentially harmful. Garcinia cambogia has been linked to liver problems and many diet supplements have voluntarily eliminated it from formulas. There are some positives in the mix, but nothing you can’t buy as part of a clinically-proven solution. Here at DietSpotlight we need to see facts proving an option lives up to its claims. Without that, we’re skeptical.

The Bottom Line – Does Slim Science Work?

Well now, what do with have to say this time around? We like that it’s easy to buy Slim Science and that it’s affordable, but we have concerns recommending this to our readers as an effective and safe way to lose weight. The lack of published studies proving it is more than just a multivitamin was a big factor, but we’re also concerned about some of the ingredients and the potential to side effects. We also didn’t like the high ratio of negative to positive reviews and the lack of results.

If you’d like a healthy way to lose weight, we suggest you go with a proven formula that is backed by published scientific research and has ingredients that support weight-loss without unintended side effects.

Among the best products we’ve seen in 2016 is one called Leptigen. This formula contains just four ingredients in a proprietary blend that has been shown in published research and unbiased studies to help boost weight-loss by accelerating fat loss and sparking metabolism. Users online seem to love the results that they’ve experienced and we can’t find any hint of negative side effects.

Right now, the makers of Leptigen are showing just how confident they are in their product by offering a Special Trial Offer.

What You Should Know

Slim Science is a weight loss program from AmeriSciences. There are three supplements included - Slim, Carb Right and Energy. When the three are combined they are supposed to support weight loss and make it easier to eat right. Information on the program is scattered all over the Internet, but not on the official AmeriSciences website. That site appears to be down for maintenance, but there is some skepticism about whether or not it will ever be live. We found the three supplement weight loss program for sale on a spinal health website for $250. That is MUCH more than we would suggest the dieter spend for this program.

Product Features

The three supplements in Slim Science are pretty interesting. One is added to boost metabolism with ingredients like green tea, garcinia cambogia and cola nut. The garcinia cambogia is associated with negative side effects, including liver damage, so we'd suggest dieters skip this portion of the Slim Science program.

Carb Right contains ingredients to control blood glucose response. This is the best supplement in the Slim Science trio. Carb Right may help control hunger, which is the biggest reason why dieters fail to stick with a diet plan.

Energy is a combination of ginseng, guarana and green tea. This is the better slimming formula of the two stimulant-based supplements in the Slim Science program. When this supplement is taken with the Carb Right, you may notice increased energy, metabolism and weight loss while feeling less hungry.

  • All ingredients were listed online.
  • The three formulas all contain at least one proven ingredient.
  • Green tea and caffeine are two of the best weight loss ingredients.


  • We are not fans of garcinia cambogia.
  • The Slim Science program is extremely expensive.


If you want to lose weight with a complete program, Slim Science is good if you take out the Slim supplement. However, there are weight loss supplements that contain most of the ingredients in the Carb Right and Energy supplements in the program. There is no sense in paying this much money for three supplements when you can find one supplement with clinically tested and supported ingredients.
