Industrial Applications
(-)-Epigallocatechin is primarily utilized as a bioactive ingredient in the nutraceutical industry due to its well-documented health-promoting effects. Key applications include:
- Formulation of antioxidant-rich dietary supplements targeting cardiovascular and metabolic health.
- Incorporation into functional beverages and foods to enhance nutritional profiles with natural plant-based actives.
- Use in cosmeceutical products for its skin-protective and anti-aging properties, though this product is optimized for oral consumption.
- Serving as a reference standard or key component in research on polyphenol bioactivity and protein aggregation inhibition.
Its ability to interact with unfolded polypeptides and inhibit amyloid fibril formation underscores its relevance in advanced nutritional science. As a drop-in replacement for other green tea catechins, it offers formulators a reliable, high-performance ingredient backed by extensive scientific literature.
