I am sorry to say that it does not work. Plenty of claims, actually the claims have been out there for over 20 years. No true unbiased research on proving it effective. All the 'studies' are sponsored by the company that makes the product. Acarbose and miglitol are prescription drugs that do work but have some side effects.
Do white kidney bean extract supplements effectively block carbs? For instance, this product: https://supplementpolice.com/carb-block-ultra/ If that isn't a good product, what supplement do you recommend to help block the absorption of carbohydrates? Thank you, Dr. Garcia.
