Razberi-K® raspberry ketone - This is a major aromatic found in red raspberries. Raspberry ketone helps with weight reduction through two mechanisms:
1) Enhancing the breakdown ("burning") of fat - The chemical structure of raspberry ketone is similar to the structures of capsaicin and synephrine, two compounds known to exert anti-obesity actions and alter fat metabolism in favor of fat weight loss. Raspberry ketone increases a process known as norepinephrine-induced lipolysis. Additionally raspberry ketone supplementation appears to result in a higher secretion of the hormone adiponectin. Both of these effects - increased norepinephrine-induced lypolsis and higher levels of adiponectin - enhance fat metabolism.
2) Decreased fat absorption and storage - Raspberry ketone assists in inhibiting a primary step in the absorption of fat, trioleoylglycerol hydrolysis. Additionally, not only does an increase in adiponectin result in increased metabolism of fat, it also is associated with a decrease in fat storage.
