- Medication Interactions: Possible interactions with blood thinners and blood pressure medications.
- Caffeine Sensitivity: Black tea contains caffeine, which may affect sleep or induce jitters in sensitive individuals.
- Caution in High Doses: Animal studies indicate potential risks with excessive doses.
Dietary and Natural Sources of Theaflavins
The primary natural source of theaflavins is black tea, which is created through the oxidation and fermentation of green tea leaves. This process transforms catechins, especially EGCG, into theaflavins and other polyphenols unique to black tea. Regular consumption of brewed black tea allows individuals to naturally obtain the benefits associated with theaflavins without the need for supplements. Green tea and black tea both contain tea polyphenols, though theaflavins are exclusive to black tea due to their unique fermentation process.
While fresh green tea leaves are known for their high catechin content, which provides strong antioxidant benefits, black tea’s theaflavins have their own set of health-promoting effects. Both types of tea support wellness, though black tea’s unique theaflavin derivatives are particularly noted for supporting heart health and potentially reducing oxidative damage linked to chronic disease.
Natural Sources of Theaflavins:
- Black Tea: The primary source, rich in theaflavins due to fermentation.
