Containing two recently popular diet pill ingredients, BioGenetic Laboratories Razberri Ketone-Slim is said to greatly enhance weight loss. Allegedly, it also curbs appetite, boosts energy, and eliminates toxins.

Unfortunately, weight loss pills promising multiple benefits are all too common. To measure how Razberri Ketone-Slim stacks up, I looked at its maker, ingredients, reviews, cost, and directions. Keep reading to learn what I uncovered.

Razberri Ketone-Slim: The Company Behind It

BioGenetic Laboratories manufactures Razberri Ketone-Slim for the supplement company iSatori Technologies.

According to iSatori’s website, iSatori aims to provide consumers with high-quality health products and live up to its core principle of integrity.

In keeping with these aims, iSatori has a good reputation with the Better Business Bureau. Although iSatori is not officially accredited with the BBB, the company has an A+ rating on the BBB website. A few consumers have filed complaints against iSatori. But, iSatori resolved these complaints.

It’s nice to see a health supplement company striving for excellence instead of just profits. Even so, iSatori’s good reputation doesn’t guarantee Razberri Ketone-Slim’s weight loss efficacy.

Razberri Ketone-Slim: The Ingredients Inside It

To determine if Razberri Ketone-Slim enhances weight loss and provides the additional advertised benefits, I examined studies of both active ingredients.

Raspberry Ketone
Raspberry ketone is a chemical used in many diet pills to promote weight loss. [1] Unfortunately, not many raspberry ketone studies exist, despite its growing popularity.

The most cited and most relevant raspberry ketone study was performed in 2005. In this study, mice eating a high-fat diet failed to gain weight when they also consumed raspberry ketones. [2]

That outcome doesn’t exactly scream “miracle weight loss ingredient.” Still, this study has spawned a fleet of diet pills, including Razberri Ketone-Slim.

Green Coffee Bean Extract
Green coffee bean extract contains a chemical called chlorogenic acid. Because of this, green coffee bean is said to be capable of causing weight loss without diet or exercise. [3]

The best green coffee bean extract weight loss study used doses of either 700 mg or 1050 mg daily. At both these doses, participants lost weight. But, measuring weight loss results in this study is difficult because of its design. [4]

Of Razberri Ketone-Slim’s two active ingredients, green coffee bean has stronger research supporting it as a weight loss enhancer. The raspberry ketone studies are too preliminary. Plus, they don’t suggest an effective human dose.

In addition, studies indicate the effective green coffee bean extract dose is at least 700 mg. A daily Razberri Ketone-Slim serving contains only 400 mg. Unfortunately, there’s no evidence to prove such a small dosage induces fat burning.

Razberri Ketone-Slim: The Consumer Reviews has 28 reviews from Razberri Ketone-Slim users. To give you a sense of consumer opinion, I’ll share some of their comments.

jasonbiberston: “I followed the directions faithfully and lost 12 pounds with the first bottle. Im now on my second and have lost an additional 4 pounds so far. The energy that I get and general overall well being are well worth it. i love this product. I havent tried anything else and i dont think i will.”

cartoon2125: “I’m not overweight but I have put on couple of extra pounds during summer. I was hoping that this will help me get more energy and lose 4-5 pounds but not only I didnt lose it, I didnt even get any extra energy!!!!”

apostles39: “I would have to say that the first thing that I began to lose were inches. I have been on the products now for a week and I have lose not only inches but 3 lbs.”

These reviews clearly show the three basic opinions consumers expressed about Razberri Ketone-Slim. Like jasonbiberston, some people praised it up and down. This group represents the largest number of reviewers. Others, like cartoon2125, were mostly dissatisfied. And, a few had a more toned-down praiseworthy opinion.

These comments suggest Razberri Ketone-Slim is effective in some people. But, these reviews are not a sufficient substitute for clinical tests of Razberri Ketone-Slim’s weight loss formula.

Razberri Ketone-Slim: The Price

Razberri Ketone-Slim can be purchased directly from BioGenetic Laboratories or from several health supplement stores and websites.

BioGenetic Laboratories offers consumers a discount for buying multiple Razberri Ketone-Slim bottles at once. Buying 1 bottle costs $48 plus a $9.95 shipping charge. But, buying 2 earns customers a free bottle and total cost is $96. Buying 3 bottles comes with 2 free bottles for a total cost of $145.

Another reason to buy directly from BioGenetic Laboratories is the return policy. Razberri Ketone-Slim has a 60-day money-back guarantee. However, this only applies to purchases made on

Of course, many health supplement websites feature more competitive pricing on 1 Razberri Ketone-Slim bottle. The best deal is from, for $48.99 with a 60-day money-back guarantee.

Razberri Ketone-Slim: The Use Instructions

A Razberri Ketone-Slim serving is 2 capsules. Take 1 serving before breakfast and another 6 hours later. Always take Razberri Ketone-Slim on an empty stomach and with water.

For best results, Razberri Ketone-Slim needs to be used with a specially designed complementary diet plan. Unfortunately, details of this diet plan are not provided before purchase.

Razberri Ketone-Slim: Is It a Quality Diet Pill?

It’s hard to draw any firm conclusions about BioGenetic Laboratories Razberri Ketone-Slim’s efficacy. The current science on its ingredients contradicts the largely positive customer reviews.

If you want to try it, Razberri Ketone-Slim could give you the weight loss results you want. But, I’m not convinced it will. It might be wiser to try a diet pill with more proven ingredients.
