Procyanidin B2 Research

Dr. Rassman, I know you get questions about procyanidin b2 every day and I understand enough data is not currently available to determine whether the product is indeed efficient. But my question to you is: is research on it being done by serious, credible institutions? Can we expect to see any YES/NO recommendation that can actually be trusted any time soon? Thanks!

The bulk of research on procyanidin B2 is published by one group of authors in Japan in last few years. Although some of them are published in peer reviewed medical journals mostly on small group of patients, more research with a larger number of patients seems to be necessary for assessing the efficiency and safety of this product.
