Beyond Bioavailability — What Research Shows About Flavanols' Effectiveness
- Flavanols are plant compounds in cocoa, berries, and tea with low bioavailability, meaning only a small portion enters the bloodstream
- A new animal study found that oral flavanol doses of 25 to 50 milligrams per kilogram (mg/kg) activated the subjects' brains within minutes
- Flavanols are a type of flavonoid within the polyphenol family. This hierarchy clarifies their differences and explains why foods have unique combinations that offer specific health benefits
- If you choose cocoa flavanol supplements, don't fall for flashy marketing; whenever possible, stick to a nutritious food-first approach
- Along with consuming flavanol-rich foods, pairing them with regular physical activity and a nutrient-dense, plant-focused diet helps support long-term brain health and cardiovascular resilience
