What is it?
People take raspberry ketone by mouth for weight loss. It became popular for weight loss after it was mentioned on the Dr. Oz television show during the segment called "Raspberry ketone: Miracle fat-burner in a bottle" in February 2012.
People apply raspberry ketone to the skin for hair loss.
Raspberry ketone is also used in foods, cosmetics, and other manufacturing as a fragrance or flavoring agent.
How effective is it?
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for RASPBERRY KETONE are as follows:
Insufficient evidence to rate effectiveness for...
- Hair loss (alopecia areata). Early research shows that applying a raspberry ketone solution to the scalp might increase hair growth in people with hair loss.
- Male pattern baldness (androgenic alopecia). Early research shows that applying a raspberry ketone solution to the scalp might increase hair growth in people with male pattern baldness
- Obesity. Early research suggests that taking raspberry ketone plus vitamin C might decrease weight and body fat in healthy people. Other research suggests that taking a specific product (Prograde Metabolism) containing raspberry ketone (Razberi K, Integrity Nutraceuticals) and other ingredients including caffeine twice daily for 8 weeks reduces body weight by 2%, fat mass by 7.8%, waist circumference by 2%, and hip circumference by 1.7%. The effects of taking raspberry ketone alone are not clear.
- Other conditions.
How does it work?
Are there safety concerns?
There isn't enough reliable information available to know if taking raspberry ketone alone is safe. There are some concerns about the safety of raspberry ketone because it is chemically related to a stimulant called synephrine. Therefore, it is possible that raspberry ketone might cause feelings of jitteriness, increase blood pressure, or rapid heartbeat. In one report, someone who took raspberry ketone described feelings of being shaky and a pounding heart beat (palpitations).
Special precautions & warnings:Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking raspberry ketone if you are pregnant or breast feeding. Stay on the safe side and avoid use.
Diabetes: Raspberry ketone might lower blood sugar levels. In theory, raspberry ketone might make blood sugar drop too low in people already taking medications for diabetes.
Are there interactions with medications?
- Medications for diabetes (Antidiabetes drugs)
- Raspberry ketone might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking raspberry ketone along with diabetes medications might cause your blood sugar to get too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications used for diabetes include glimepiride (Amaryl), glyburide (Diabeta, Glynase PresTab, Micronase), insulin, metformin (Glumetza, Fortamet, Glucophage, Riomet), pioglitazone (Actos), rosiglitazone (Avandia), and others.
- Warfarin (Coumadin)
- Warfarin (Coumadin) is used to thin the blood and prevent blood clots. There has been one report of a person taking warfarin (Coumadin) who also took raspberry ketone. In this person warfarin (Coumadin) did not work as well after raspberry ketone was taken. The dose of warfarin (Coumadin) had to be increased in order to maintain the effect of warfarin (Coumadin) and prevent blood clots. If you take warfarin (Coumadin), talk with your health provider before taking raspberry ketone.
Are there interactions with herbs and supplements?
- Herbs and supplements that might lower blood sugar
- Raspberry ketone might lower blood sugar levels. Taking it along with other herbs and supplements that might lower blood sugar could lower blood sugar too much in some people. Some herbs and supplements that might lower blood sugar include alpha-lipoic acid, bitter melon, chromium, devil's claw, fenugreek, garlic, guar gum, horse chestnut, Panax ginseng, psyllium, Siberian ginseng, and others.
Are there interactions with foods?
- There are no known interactions with foods.
