The editors at Examine.com recently updated the page on raspberry ketone. This supplement has stepped out of the spotlight lately, but it remains popular and we receive a lot of questions about the effectiveness of raspberry ketones.

Though raspberry ketone were featured often in the media last year, not very much additional research has been conducted on the supplement since. The in vitro (in a test tube) data suggests supplementing raspberry ketones is ineffective and impractical due to the very high concentrations used to achieve any fat burning effect. Studies done on rats also note the sheer amount of raspberry ketones the rats needed to be fed in order for the researchers to observe any benefits. One human study did investigate raspberry ketones, but the supplement was used alongside many others, and benefits could not be traced back to raspberry ketones specifically.

If you take a look at our page, you’ll notice our Human Effects Matrix (HEM) suggests that raspberry ketone might provide aesthetic benefits, like improved skin elasticity and hair regrowth. These effects have only one trial’s worth of evidence behind them, meaning further research is needed to confirm the effects of raspberry ketone on hair and skin. Keep in mind as well, these effects are not exclusive to raspberry ketones. Green tea catechins and cinnamic acid, both with a molecular structure similar to raspberry ketone, have been shown to smooth skin and regrow hair.
