Raspberry ketone, 4-(4-hydroxyphenyl)-2-butanone), is a phenolic compound highly concentrated in red raspberry.  This compound gives red raspberry its fruity aroma [**].  Though in less quantity, it is also present in brewed coffee, kiwi berry, peaches, grapes, berries, maple, and pine [**]. 

Research suggest that raspberry ketone have anti-obesity [*], cardioprotective [*], hair growth promoting [*], anti-diabetic [*], gastroprotective [*], hepatoprotective [*], anti-inflammatory [*], and antioxidant properties [*]. 

Though existing studies suggest that raspberry ketones have potential health benefits,  additional research is still necessary to establish its efficacy and mechanism of action [*]. 

The extraction of raspberry ketone is very expensive, hence it is often chemically synthesized or biosynthesized from bacteria or yeast [*]. 

In the United States, raspberry ketones are generally recognized as safe (GRAS) [*].

Raspberry ketones are widely used as a flavoring agent in food, beverages, cosmetics, and perfumes. There are also a wide variety of dietary supplements that contain raspberry ketones as a single ingredient or part of a blend. These products claim to help with weight loss [*].

The popularity of raspberry ketones has led to hundreds of brands flooding the marketplace; however not all supplements are created equal! Unfortunately, more than 90% of raspberry ketone supplements in the market simply DON’T WORK!

We understand the challenges in finding the right supplement for your health needs. That’s why we gathered years of research and made this guide to help you find the top-rated formulas that work for you.

Things To Be Cautious About

Has your brand been third-party tested? You should never buy supplements that don’t have Certificate of Analysis. The studies should be conducted in labs that are not affiliated with the manufacturer. These labs verify the product for safety and potency.

Does your raspberry ketone contain cheap synthetic fillers? Some brands add artificial fillers to cut cost to offer cheap products. Some of these cheap fillers we found were titanium dioxide and artificial coloring. You should never purchase cheap products when it comes to supplements.

No return policy or customer service – A reputable supplement company will offer 100% money-back guarantee policy and provide customer support through phone number and email. We noticed many formulas out there are just copies of the top-rated brands. They don’t offer an easy refund policy or don’t even have a phone number to prove they are real.
