Most plants contain a molecule or substance called raspberry ketones (Razberi K, Integrity Nutraceuticals), which is responsible for giving them their sweet aroma. These plants include red raspberries, kiwifruit, peaches, grapes, apples, and other berries, as well as vegetables such as; rhubarb, the bark of yew, maple, and pine trees.

Here is everything you need to know before Buying the Raspberry Ketone supplement :

What is Raspberry Ketones

Raspberry ketone has gained popularity with so many companies where they are extracted from any of these fruits and vegetables for various purposes ranging from weight loss, cosmetic use like perfumery and lotions, etc., and in the food industry as a flavoring agent like in soft drinks and ice creams, sweets, etc. 

Some reviews say confirm how expensive it is to extract raspberry ketones from plants where a single dose of raspberry ketone requires over 41 kg of plants. 

It is on that note that most companies opt for using a synthesized raspberry ketone instead of the natural form. 

Thus, laboratories synthesize raspberry ketones for commercial purposes in order to save costs companies resort to the latter. As such the synthesized product will still exhibit the flavors and the sweet aroma found in the natural raspberry ketone

Some active ingredients found in Raspberry Ketones

The raspberry ketone diet pills gained its popularity in 2012 when it was talked about on Dr. Oz television show which was discussing raspberry ketones and the guests were singing praises on how the product has worked miracles in curbing obesity. 

Moreover, in studies conducted on rats and on cells grown in laboratories, Raspberry ketones supplement was found to increase the fatty acid oxidation thereby stimulating adiponectin, a hormone which reduce appetite and also speed up the rate at which the body burn fat. The adiponectin hormone is also known to suppress appetite.

Adiponectin hormone 

Normal body weight is associated with high levels of adiponectin and as such overweight and obese people are said to have lower levels of this hormone which further predisposes them to; obesity, type 2 diabetes, fatty liver disease and even heart disease.  

Thus, aiming to elevate adiponectin levels will not only help people lose unwanted weight, it will also prevent and reduce the risk of many diseases. Having the ability to increase adiponectin is an added advantage for the raspberry ketone supplement. 

Furthermore, the adiponectin in the Raspberry ketones has abilities to boost one’s metabolism, and thus converts the body’s fats into essential energy after burning it and when that happens a person gets to lose weight as the process whereby a body stores fat cells leading to weight gain gets interrupted.

However, people consuming these pills will still need to adopt a healthier lifestyle (exercise) and good eating habits (avoid eating junk) for them to see the results faster. 

Garcinia Cambogia

The weight loss supplement also has a fat blocker called Garcinia Cambogia as an active ingredient which is useful in the inhibition of Citrate Lyase enzyme which means the body will no longer make and store fat after the body get food.

Also, people who use raspberry ketone supplements are not prone to depression, mood swings, and short temper which are the most common side effects suffered by most weight loss supplements users. 

This is because the Citrate Lyase enzyme is known to elevate the level of the Serotonin hormone enabling users of raspberry ketones users to do it with ease.

Furthermore, the two active ingredients on the supplement pills marry very well, where consumers taking the pill have their bodies blocking the formation of fat (Garcinia Cambogia) as well as having the fat consumed from food converted into essential energy (Raspberry ketone) for body use with little to no fat storage.

Are Raspberry Ketones good for you

The raspberry ketones supplement pills are extracted from natural sources; it was NOT synthesized from the laboratories. The product is free from, additives, binders, fillers, and artificial ingredients, and as such the product passed when tested against the monographs in USP/NF for standardization.  

One review has shown that people who combined 200 mg of raspberry ketone supplement with 1200 mg of vitamin C daily for 4 weeks were found to have lost a significant amount of body fat and weight. 

Regrettably, the study s reliability is flawed because Improper scientific methods were used to conduct the study and the results, therefore, are not to be trusted. Moreover, the findings do not show if the weight loss was the result of raspberry ketones alone, vitamin C alone, or a combination of both.

Our conclusion

Raspberry ketones were not synthesized in a lab and as such, it is a completely natural product. Natural products are safer for consumption than synthesized ones. The active ingredients in the supplement give use double action: fat blocking and fat burning in one product. 

Although the supplement suppresses appetite, less food intake by users while keeping their serotonin levels at par enables users to stay in a mood good. 

Overweight and obesity are experienced as a result of poor eating habits and lack of physical activities. Inasmuch as raspberry ketones is good, users who do not change their eating patterns and add a little physical activity WILL NOT see the desired results. It is important to know that the product needs to be supplemented by good and healthy behavioral change. 

However, this is one product that has a multilevel efficacy index resulting from the few rigorous reviews conducted by reputable researchers on humans. This goes on to show that more research needs to be done, legitimately to ensure that the users of raspberry ketones supplement users get value for money and ultimately, the public is protected. 

It is not good when the public is left with uncertainties like this. In this case, the uncertainty does not predispose users to some health hazard and that is comforting. The only expected outcome with the product users here will be whether the person will lose weight or not.
