I've been reading about certain special microencapsulated medicine. They claim the acid in the stomach decreases the true amount and quality of the medicinal benefits. Makes sense to me. So knowing this, how beneficial are any orals, unless they have some sort of protective coating to withstand some of the harsh acids. Is there any difference between vitamin C from one company versus another--if they are theoretically of the same quality. So it might be more a matter of presentation to achieve the maximal benefit.
