DOES IT WORK?
Results vary. Raspberries are genuinely nutritious, with high ellagic acid content and good antioxidant capacity. But as a supplement ingredient in blends, the doses are typically too small to deliver meaningful benefits. And don't confuse raspberry fruit with 'raspberry ketones,' which are a separate compound with almost no evidence for fat loss despite the marketing hype.
