Razberi-K appears to support reductions in body fat in two ways. First, decreasing the absorption of dietary fat and secondly, increasing norepinephrine-induced lipolysis. In another study researchers were able to demonstrate that Raspberry ketone was capable of inhibiting alpha amylase activity a dietary enzyme involved in starch breakdown and sugar absorption, helping reduce fat.
In the study by Morimoto et al., 2005 they demonstrated that raspberry ketones supplementation resulted in an increase in Hormone Sensitive Lipase (HSL) translocation to fat cell lipid droplets suggesting that raspberry ketones enhances norepinephrine Lipolysis (fat burning). Research has also shown that raspberry ketones stimulates an increase in thermogenesis in brown adipose (fat) tissue.
In a field study by Tim Ziegenfuss, ten participants received a 200 mg per day Razberi-K supplement along with exercise. This was done to assess the effects of RK on fat oxidation and blood chemistry, the results showed a trend toward enhanced fat oxidation as shown with a 62% increase in Respiratory Exchange Ratio (RER) and no adverse effects on blood chemistry were observed implying RK's safety and efficacy.
