If you are like so many others who want to lose weight in a safe manner, then it is natural to only want to use the highest quality ingredients in a supplement. If so, then you are smart to buy only certified raspberry ketones. But then the next concern is how can you be sure about the quality? And what indicators should you look for when shopping?
Before delving into the answers to those questions, let’s consider a few questions to help clarify matters.
- What is meant by certified and what exactly is being certified?
- Is it the purity of the raspberry ketone ingredient?
- Does certified refer to the source of the substance?
The Source of Raspberry Ketone in Supplements
As you may know, raspberry ketone can be synthesized in a laboratory. Some websites talk about the quantity of real raspberries needed to make sufficient amounts of ketones. The numbers vary but some sites report that up to 100 pounds of the fruit are needed to produce 100 mg of RK.
At present, there is very little available information to confirm the precise answers to the above questions. But there are some quality indicators you can look for on websites. For example, the website for Raspberry Ketone Plus states their ingredients are supported by a Certificate of Analysis (COA).
Quality Indicators to Help You Decide
A COA (Certificate Of Analysis) is a document attesting to the fact that a series of visual and chemical analyses were performed on a sample of the product. A real example of a COA for raspberry ketone ingredients in a weight loss product will be given, below.
An assay is an analytic method to determine the purity of a substance. In this example, the specification was 99.0%, and the test result for this sample was 99.79%. The COA also reveals the type of analytical test method used.
Another important measurement for this ingredient in the COA testing process is the melting range. The melting temperature of a substance is a reliable test to help determine quality and identification. The COA in question specifies a melting range temperature of 82.0 to 84.0 Degrees F. The test result was 82.3 Degrees F.
One thing the COA does not precisely indicate is the source of the raspberry ketone. But there is something that could lead you to suspect it is synthetic ketones. There is a CAS number assigned to the substance being tested. So what is a CAS number?
A CAS Registry number is a unique number assigned to every single chemical known or described in the openly available scientific literature. That number is assigned by an organization known as the Chemical Abstracts Service (CAS).
There is additional information you can look for on websites, or product labels, to indicate the ingredients meet certain standards. For instance, products made in the US may be manufactured in an FDA registered laboratory. FDA stands for Food & Drug Administration and is a federal regulatory and oversight agency.
The FDA has strict guidelines mandated in their GMP (Good Manufacturing Practices) certification which registered labs must follow. You can also look for the GMP seal on websites and product labels.
Conclusion and Considerations
It is highly likely that weight loss products containing raspberry ketone do not contain ketone made from real raspberry fruit. The cost certainly seems prohibitive considering that amount of fruit needed to produce so little raspberry ketones. One common marketing claim in these products refers to the purity of the ketone. But going beyond that, you would be wise to choose a raspberry ketone supplement from a website, or company, practicing transparency.
In other words, do they have a COA for you to view or verify? Are their products made in an FDA laboratory or similar agency if not in the US? Are the products made in accordance with accepted high quality standards?
