Background
Raspberry ketone is a chemical that is found in red raspberries and other fruits. It's popular for obesity, but it's not clear if it helps.
It's believed that raspberry ketone might increase metabolism, increase how quickly the body burns fat, and reduce appetite. But evidence in humans is limited. Raspberry ketone is also found in kiwifruit, peaches, grapes, apples, other berries, rhubarb, and the bark of yew, maple, and pine trees.
People use raspberry ketone for obesity, hair loss, male pattern baldness, and other conditions, but there is no good scientific evidence to support these uses.

Interactions with pharmaceuticals
Stimulant drugs
Interaction Rating=Moderate Be cautious with this combination.
Stimulants, such as amphetamines and cocaine, speed up the nervous system. By speeding up the nervous system, stimulant medications can increase blood pressure and speed up the heartbeat. Raspberry ketone might also speed up the nervous system. Taking raspberry ketone along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure.
Warfarin (Coumadin)
Interaction Rating=Moderate Be cautious with this combination.
Warfarin is used to thin the blood and prevent blood clots. Raspberry ketone might reduce the effects of warfarin, which could increase the risk for blood clots. If you take warfarin, talk with your healthcare provider before taking raspberry ketone.
Interactions with herbs & supplements
Herbs and supplements with stimulant properties: Raspberry ketone might have stimulant effects. Taking it with other supplements with similar effects might increase the chance of side effects, including rapid heartbeat and high blood pressure. Examples of supplements with this effect include 1,3-DMAA, bitter orange, caffeine-containing products, DMHA, and ephedra.
Interactions with foods
