I’m surprised to hear someone speak out about taking a multivitamin at all… I read through the article you linked to and for the most part, it just lists how a specific vitamin was not proven to help a specific condition. And in several cases, it’s not even that a connection was found, they just didn’t find a benefit. I’m not trying to gloss over that several found elevated levels of a vitamin had adverse effects as well, increasing the occurance of serious diseases.
As for there never being any data as to the benefits, even that particular article mentions three or four times that there are benefits to certain vitamins for certain groups. And it’s an article written to illuminate the dangers… the supplement industry didn’t develop overnight.
I believe the vitamins you’re talking about sell because honestly, how would I know if I’m deficient in something specifically? Do I wait for symptoms? If I don’t get enough leafy greens, does a warning light go on? I honestly don’t know until I get sick (which the root cause of is rarely the focus of treatment) or I stumble upon something that contains what I’m missing and also paying enough attention to notice the benefits.
A multivitamin at least helps me make sure I’m getting the minimum levels of what I need. If my wife is anemic, she gets iron, if I’m not getting enough calcium because I don’t drink milk, that makes sure I get some… it’s not a cure all, it’s preventative.
If there’s a simple way to tell what I’m deficient in, without encountering symptoms, I’d love to try it. And then I would alter my diet to compensate for that or take just the things that I need as a supplement. Unfortunately I don’t know if there is a such a thing, when I go to the doctor for a checkup, they essentially come back, say I’m healthy, and that’s the end of it. If I don’t have symptoms, I must be fine, right?
It seems if there is something in the supplement industry to rally against it would be the items intended to fill a specific need with no science or study behind them. Those could be truly dangerous and should be tested and regulated.
I’m getting long-winder here and I apologize, it’s important to say that I understand that this is your area of expertise and it is not mine, so I respect what you say. I’d just like to understand the alternatives.
