The U.S. Food and Drug Administration first categorized raspberry ketones as a “Generally Recognized as Safe” (GRAS) food additive in the 1960s. However GRAS status is given under the assumption that a person will consume less than two milligrams of raspberry ketone a day. Most weight loss supplements pack far more raspberry ketone into their products. Raspberry ketone is well studied at concentrations used in supplements – which can range from 50 to 250 milligram per serving. And there are no known side effects from their use. Raspberry ketone may lower blood sugar levels. Raspberry ketone may also cause changes in body fat and weight.
In a 2015 study, published in the journal Regulatory Toxicology and Pharmacology, researchers in Denmark used a model to look at the potential effects of raspberry ketone on the human body. Their findings suggested that raspberry ketone could not have potentially toxic effects. “The compound’s toxic potential should be clarified more with further experimental studies,” the researchers said.
Take Raspberry Ketones supplement before meals or before heading for the gym. The advantage of the capsules is that you always get an exact measure, and once you know how much you should be taking, it’s a lot easier to stick to that amount. Over time you can increase your intake to 3 times the above-mentioned amounts, but this should be done gradually and only when no side effects are noticed. There is no scientific evidence of any safe upper limits, but we strongly suggest that you don’t overuse the product. They are meant to support your diet and exercise routine, and if you think that it can become a replacement, then you’re setting yourself up for trouble. Read the product label carefully. You may also get in touch with a healthcare professional or pharmacist to find out the right dosage for your body weight correctly.
