Remission of impaired glucose tolerance by anthocyanin supplementation: a randomized, double-blind, and placebo-controlled trial

Puntos clave

• Glucose tolerance improves significantly with anthocyanin supplementation from 12 weeks onward, suggesting its beneficial effects.
• Participants reported a notable increase in insulin sensitivity after receiving anthocyanin compared to placebo, highlighting its potential.
• Randomized controlled trial combining double-blind and placebo-controlled design underscores the reliability of findings on glucose metabolism.
• These results suggest that dietary anthocyanins could play a crucial role in managing impaired glucose tolerance in the population.
