Effect of Raspberry Ketone on Normal, Obese and Health-Compromised Obese Mice: A Preliminary Study

Area of Science:

• Pharmacology and Toxicology
• Obesity Research
• Nutraceutical Safety

Background:

• Raspberry ketone (RK) is a widely used over-the-counter weight loss supplement derived from red raspberries.
• Obesity and compromised health conditions are significant public health concerns, with many individuals seeking dietary interventions.
• The safety profile of raspberry ketone, particularly in vulnerable populations, requires thorough investigation.

Purpose of the Study:

• To evaluate the adverse effects of raspberry ketone (RK) administration in diet-induced obese mice.
• To assess the safety of RK in a health-compromised obese mouse model.
• To determine the dose-dependent toxicity and potential health hazards associated with RK supplementation.

Main Methods:

• Two mouse models were used: normal obese and health-compromised obese (induced by lipopolysaccharide).
• Mice were treated with varying doses of RK (165, 330, 500 mg/kg) for 10 days.
• Body weight changes, mortality rates, blood alanine transaminase (ALT) levels, and blood glucose were monitored.

Main Results:

• Raspberry ketone administration retarded body weight gain in both obese and health-compromised obese mice.
• Significant mortality rates were observed at higher RK doses (330 and 500 mg/kg), with earlier deaths at higher concentrations.
• Elevated blood ALT levels and significantly increased blood glucose were noted in RK-treated mice across all groups.

Conclusions:

• Higher doses of raspberry ketone may induce adverse effects, particularly in health-compromised individuals.
• Prolonged use of RK, especially at elevated doses, could pose a health risk.
• Further research is warranted to fully elucidate the safety and toxicological profile of raspberry ketone.
