Yes, I'd say there's probably a cultural difference here. Vitamins are not high on the list of things doctors think about when they see a patient here in the U.S. I think there are valid reasons for this - vitamin deficiencies are super rare and there isn't a ton of evidence that much higher levels of any vitamin does anything. Herbs, amino acids, compounds, minerals ... there's a snarky comment below about doctors here not getting paid to push those and sadly that's largely true. Doctors will literally hand out promotional drugs to patients. It's a kind of bizarre situation. Worse yet, unless formulated into a "drug," a manufacturer cannot claim that a substance can cure or prevent a disease. There are two (and a half) sides of this coin. On the one hand, it means that you cannot sell a bottle of Vitamin C that says "will cure and prevent scurvy." On the other hand, the supplementation market is largely unregulated. That's good because people have access to many substances that have a lot of science behind their benefits without waiting on the FDA. And here comes the half - it means that companies can sell things that are dangerous and/or of dubious content. A largely untenable situation for a consumer, but money drives everything.
