Dosage and type of anthocyanin (food, juice, freeze-dried powder or extract).

In other studies, however, researchers identified many factors that led to mixed results, such as:

The study found there was a consistent lowering effect on blood pressure. Study participants with hypertension took a variety of extracts and preparations from anthocyanin-containing plants.
