Q. Can you recommend a carbohydrate blocker?

A. We have done some in-house testing with phaseolamin, the new over-the-counter starch blocker. Our trials did not indicate that it worked well and we decided not to offer it as one of our products. To my knowledge, there are no effective OTC starch blockers at present. An effective prescription carbohydrate blocker that has impressive research is Bayer's Precose. Please see your healthcare provider for more information.
