Over 200 different molecules give raspberries their unique flavor, one of these being what’s known as the raspberry ketone. This particular molecule was singled out decades ago given that has a particular odor. Many things today that smell like raspberries such as candles, soaps or various candies likely use this molecule. In recent years much public attention has been given to raspberry ketones, but for their weight loss properties instead.
The same molecule that’s found in raspberries is also found in cranberries or blackberries, known as the species Rosaceae Rubus Ideaus. Red raspberries are formed in the United States, North America, Europe and Northern Africa. Contains several other nutrients that are important such as vitamins A, E and C as well as beta-carotene. Naturally there only trace amounts of raspberry ketones found in the fruit itself, typically the flavoring agents actually come from laboratory settings.
Scientists began noticing that raspberry ketones similar structure to capsaicin, this ingredient is found in chili peppers and has been linked in the past to weight loss. Once this was discovered, researchers spent significant resources looking at his interactions with human tissue and mice to see if raspberry ketones work in the same way. The results were significant indicating that, for the most part, people lose the exact same amount of weight as capsaicin were shown to cause.
Do Raspberry Ketones Actually Generate Weight Loss?
Catherine Ulbricht, who works as a senior pharmacist at Massachusetts General Hospital, indicated that there is significant research on raspberry ketones, but their health effects are currently not well understood. Her group is part of an organization who reviews different scientific evidence on the use of herbal supplements for health benefits. There has been only a few preliminary studies looking at the use of raspberry ketones as a weight loss aid, and of these only one or two have been done on human subjects. There have been several on mice which have shown significant benefits. A recent study of mice fed a high-fat diet indicated that taking raspberry ketones as an extract help to prevent liver fat deposits, and reduced “belly fat” that surrounds various organs in the abdomen.
There is been other research which shows that raspberry ketones – if applied to the skin – can actually reduce the signs of aging. A similar study to the above found that in a group of 15 people, daily applications of raspberry ketones improved skin elasticity and also generated new hair growth over approximately five months. Research on mice and in some cultures inspired even further research, but for right now there has not been significant independent study of this phenomenon in humans. Though there is strong signs this product will work well the US Department of Health indicates that the evidence thus far for raspberry ketone generated weight loss is not sufficient for universal recommendation.
Safety Analysis of Extract
The Food and Drug Administration has classified raspberry ketones as GRAS or “Generally Recognized as Safe” as a food additive starting in the 1960s. GRAS status was measured if a person took in fewer than two mg of raspberry ketone extract daily. Typically for weight loss people would take 500 to 1500 mg of raspberry ketones per day. At this level is not thought to be much of a risk to the user, however, there are some considerations to keep in mind about this higher dosage use. Catherine Ulbricht indicated that raspberry ketones may be linked to a reduction in blood sugar levels and reduce the risk of bleeding.
On account of this information, physicians recommend, as always, anyone who has a chronic health problem seek doctor recommendations before going on any weight loss regimen. There is the potential for raspberry ketones to impact important medicines, such as those dealing with blood pressure, cholesterol or irregular heartbeats. More information is needed to fully verify raspberry ketones safety are all circumstances.
