In a single-dose toxicity study on rodents, a proprietary product containing monomers and oligomers of proanthocyanidins administered (2000 mg/kg body weight) for 4 weeks showed excellent safety with no side effects 12 . Administration of the same product to 30 healthy volunteers at doses of 100 mg/day and 200 mg/day for 92 days showed good bioavailability and the liver and kidney functions as well as the hematological parameters remained within the normal ranges 12 . Therefore the likelihood of toxic or negative side effects from supplementation with grape seed extract are virtually nill.
You say the Dr assumed you were a liar. Did you ask him if that is what he thought? We can’t know what people think, we need to ask them to really know. You also say you don’t talk to Dr’s like drug addicts do. How do you know how drug addicts talk to Dr’s? Have you asked any drug addicts how they talk to Dr’s? Part of the problem is with you. Change how you view the world and be clear about what you want and things will change. Ask for what you want and get Dr’s to tell you what it is they think. Never assume.
