I want to try taking raspberry ketone supplements. Will they make my glucose levels increase?
Raspberry ketones are the latest rage, as Dr. Oz has recently created public awareness of them. Raspberry ketones (not to be confused with blood ketones) are what give raspberries their sweet aroma. Food manufacturers use them to flavor foods, but they’re also used in Japan as a weight loss supplement. Supposedly, raspberry ketones induce weight loss by increasing levels of norepinephrine, a hormone that evokes the body’s “fight or flight” response, meaning that it increases heart rate, body temperature and metabolism. It is also claimed that they increase levels of the hormone adiponectin, which is involved with blood glucose regulation. If these claims are true, the concern for people with diabetes is that norepinephrine can increase blood glucose, while adiponectin may decrease blood glucose -- thus, taking raspberry ketones could lead to fluctuating glucose levels. You should also realize that this supplement has not been studied in humans, only in mice, so there’s no proof that taking it results in weight loss, and there is no long-term safety data, either. In addition, there’s no data on how long you would need to take the supplement them to see results. I’d recommend that you discuss raspberry ketones with your healthcare provider before taking this supplement.
