BioDulse: The Effect of an Irish Seaweed Protein Extract on Glucose Control in Healthy Adults

Co-ingesting protein with carbohydrate is an effective way to improve postprandial glucose handling. The investigators have isolated and identified a bioactive protein extracted from seaweed. The investigators aim to explore how varying doses of seaweed protein influence postprandial glycaemia and insulinaemia in a healthy population.
