If there has ever been an ingredient which embodies the term hype, this is it. Raspberry ketones received nationwide popularity due to the Dr. Oz show, in which they were touted as a “wonder drug” capable of shedding countless pounds of unwanted fat via increased levels of metabolic rate and fat oxidation. While this sounds nice, the reality is that this ingredient has no scientific backing outside of a test tube.
What it does
The theory behind raspberry ketones’ ability to reduce fat is through increased fat oxidation via an increase in the hormone adiponectin. While increasing adiponectin will increase fat loss, the problem is that consuming enough of this ingredient to actually force a change in this hormone, is not currently possible with dietary supplements.
The truth behind this supplement is that unless you are simply a collection of cells in a test tube, it will not help you increase adiponectin to appreciable enough levels to burn fat.
How it works
While in vitro (test tube) studies showed promise for this ingredient, it failed to show any benefits in animal models and as a result, has not been studied further in humans. In short raspberry ketones have not proven to work in animals nor proven to work in humans.
If after reading the studies you are still not convinced, the suggested dosing of raspberry ketones equates to 870mg-6,200mg/day depending on one’s size. Split total daily dosing up into 2-3 doses per day, giving you 250mg-2000mg per serving.
