Raspberry ketones are natural phenolic compounds that give raspberries their distinctive aroma. In the context of dietary supplements, they are synthetically produced to mimic the structure of capsaicin and synephrine—compounds known for their potential thermogenic properties. These ketones are commonly marketed for weight management and fat metabolism.
Their proposed mechanism involves increasing adiponectin levels, a hormone linked to regulating glucose and fatty acid breakdown. This has made raspberry ketones a popular ingredient in fat-burning formulas, particularly among individuals aiming to support body composition goals.
While early studies were promising, much of the current evidence is based on animal or in vitro research, and human trials remain limited. Nonetheless, they are widely included in fitness supplements targeting fat loss.
Synonyms:
Rheosmin, Frambinone.
Benefits:
- May support fat metabolism
- Potential to increase adiponectin levels
- Thermogenic-like activity
- Often used in weight management supplements
Sources:
Found in red raspberries; most supplements use synthetically produced forms.
Observations:
Commonly used in capsule or powder form. Typical doses range from 100–300 mg/day. Excessive use may lead to jitteriness or elevated blood pressure in sensitive individuals. May interact with stimulant-based supplements.
