(12)Is there really a magic memory pill or a herbal recall remedy? I have been frequently asked if these memory supplements work. You know, one of the first things I like to tell people when they ask me about the supplements is that a lot of them are promoted as a cure for your memory. But your memory doesn’t need a cure. What your memory needs is a good work-out. So really those supplements aren’t going to give you that perfect memory in the way that they promise.(13)The other thing is that a lot of these supplements aren’t necessarily what they claim to be, and you really have to be wary when you take any of them. The science isn’t there behind most of them. They’re not really well-regulated unless they adhere to some industry standard. You don’t really know that what they say is in there isn’t there.(14)What you must understand is that those supplements, especially in some Eastern cultures, are part of a medical practice tradition. People don’t just go in a local grocery store and buy these supplements. In fact, they are prescribed and they’re given at a certain level, a dosage that is understood by a practitioner who’s been trained. And that’s not really the way they’re used in this country. The other thing people do forget is that these are medicines, so they do have an impact.(15)A lot of times people are not really aware of the impact they have, or the fact that taking them in combination with other medications might put you at increased risk for something that you wouldn’t otherwise being countering or be at risk for.
