Raspberry Ketones…What is the REAL TRUTH about them?
Raspberry Ketones-Not all brands are considered equal!

Note: After tons of research and investigating what manufactures are legitimate, I finally found the truth behind Raspberry Ketones and I want to share that with you.
In plants, raspberry ketone is synthesized from coumaroyl-CoA. Extraction of pure raspberry ketone is usually 1-4 mg per kg of raspberries, therefore eating raspberries or raspberry seed, leaf or fruit extracts will not yield enough of the metabolic boosting properties. The natural abundance of raspberry ketone is very low, which makes it difficult to obtain a high ketone yield in a fruit, seed, or leaf extract.
The preferred form is a synthetically produced raspberry ketone powder that can be put into a capsule. This is prepared by a variety of methods from various intermediates. One of the ways this can be done is through a crossed aldol-catalytic hydrogenation, then goes through catalytic hydrogenation to produce raspberry ketone. This method produces a 99% yield. It is used extensively as vitamins, food additives, and the cosmetic industry for scent. In 1965, the Food and Drug Administration placed raspberry ketone on generally recognized as safe (GRAS) status. There are very few manufacturers that sell this type of raspberry ketone so it is important to know more about the manufacturer before you purchase anything. We have a listing of “legitimate manufacturers” that use this process and sell to distributors. The list can be obtained by emailing: firstname.lastname@example.org
A raspberry extract from the seed, leaf or fruit makes a very good anti-oxidant, but lacks the metabolism boosting properties of a pure white raspberry ketone powder that would be put into a capsule. To put into perspective, to obtain 250mg of pure raspberry ketone, one would be required to consume between 60-500lbs of raspberries, (ketone content is dependant on harvesting times), To obtain 250mg raspberry ketone from a simple raspberry ellagic standardized extract one would have to consume 100-300 capsules of even the highest quality ellagic extract. Raspberry products that state an ellagic content are extracts and are anti-oxidants, which yield minimal metabolic boosting properties. We’ve seen these placebos being called raspberry ketone on the market and this method of marketing is not ethical. To determine if you have pure raspberry ketone extract, the purer the material the more white it will be. The purest form will be white in the form of crystal-like needles inside of the capsule.
When given to mice in high doses (up to 2% of food intake), raspberry ketone has been shown to prevent high-fat-diet-induced elevations in body weight. This effect is reported to stem from the alteration of lipid metabolism, increasing norepinephrine-induced lipolysis (fat loss). Although products containing this compound are marketed for weight loss, this effect has not been studied in humans, but we are very impressed by the preliminary results.
There are only a few manufacturers that manufacture the raspberry to its raw form. Then then supply to a laboratory. The laboratory then puts this pure Raspberry Ketone product in powder capsulized form. The best ingested capsules would be in vegetable skin, as these are easer and faster absorbtion method. Synthetic skins can be harmful. While many companies carry a variety of raspberry products, the only companies that are currently carrying a true raspberry ‘ketone’ product are hard to find on the internet because they normally just sell to resalers or retail stores.
There is a email link at the end of this blog that will supply you with that list of manufacturers and their requirements for purchasing the Rasberry Ketone power, vegetable capsules and products.
Raspberry tablets are best used in 100-500mg doses (1-2 capsules) with meals once daily. It is recommended that if you are new to taking this product, start with the lower dosages until you see how your body responds. If using twice daily, go with the lower dose range. Do not exceed 2 x 500mg doses in a single day.
Due to Raspberry Ketones action on free fatty acids, the ideal accompanying diet would be one of lower glycemic carbohydrate, higher protein and low to moderate healthy fats, in the form of fish oil, extra virgin olive oil, or macadamia nut oil. While being careful to maintain calories under your base metabolic requirements.
Mechanism of action
Raspberry Ketones are similar in structure to synephrine and capsaicin, which are both noted as being thermogenic due to their release of norepinephrine. Norepinehrine increases lipolysis (which means the breakdown of white fat cells), enhances focus and attentiveness, and suppresses appetite.
As a stress hormone, norepinephrine affects parts of the brain where attention and responding actions are controlled. Along with epinephrine, norepinephrine also underlies the fight-or-flight response, directly increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow to skeletal muscle.
Triglycerides are transported through the blood to appropriate tissues (adipose, muscle, etc) by lipoproteins such as chylomicrons. Triglycerides present on the chylomicrons undergo lipolysis by the cellular lipases of target tissues which yield glycerol and free fatty acids. Free fatty acids released into the blood are then available for cellular uptake. Free fatty acids not immediately taken up by cells may bind to albumin for transport to surrounding tissues that require energy.
is an enzyme necessary for the absorption and digestion of nutrients in the intestines. This digestive enzyme is responsible for breaking down lipids (fats), in particular triglycerides, which are fatty substances in the body that come from fat in the diet. Once broken down into smaller components, triglycerides are more easily absorbed in the intestines. Lipase is primarily produced in the pancreas, but is also produced in the mouth and stomach. Lipases also act at a specific position on the glycerol backbone of lipid substrate (A1, A2 or A3). For example, human pancreatic lipase (HPL), which is the main enzyme to break down fats in the human digestive system, converts triglyceride substrates found in ingested oil to monoglycerides and free fatty acids.
In Conclusion, Raspberry Ketones trigger a reaction throughout the body. Once ingested by the body, Raspberry Ketones trigger a norepinephrine release. This causes the release of glucose from energy stores and increases the breakdown of triglycerides into free fatty acids. Once this has been completed Lipase takes over and breaks down the fats allowing them to be digested by the intestines. With this taking place your body will need to release more free fatty acids for energy since what was stored is now being burned.
In 1965, the Food and Drug Administration placed Raspberry Ketone on generally recognized as safe (GRAS) status. Raspberry Ketones became popular in the bodybuilding subculture back in 2005, but has not gained wide popularity until 2010. More recently, Dr. Oz stated Raspberry Ketones high on his list of effective metabolism boosters, and assured their safety profile when used as recommended.
