Acute Effects of Spirulina on Postprandial Glycemic Responses and Arterial Blood Pressure

Acute Effects of Three Doses of Spirulina in Glucose Beverages on Postprandial Glycemic Responses, Arterial Blood Pressure, and Subjective Appetite Responses: A Randomized Clinical Trial

This study investigated the effects of three doses of spirulina in glucose beverages on postprandial glycemic responses, arterial blood pressure, and subjective satiety.

This study aimed to determine the effects of three different doses (4, 6 and 8 g) of spirulina in glucose beverages on postprandial glycemic responses, blood pressure, and subjective appetite responses in healthy young adults.
