But according to Dr Paul Offit, chief of the infectious diseases unit at Children’s Hospital of Philadelphia, we should reconsider how much we rely on our vitamins. Offit has garnered a lot of attention over the past month for his anti-supplement stance, as laid out in his recent book Do You Believe in Magic?: The Sense and Nonsense of Alternative Medicine.
In it, Offit says that vitamin supplements are far from a panacea – in high doses, they may actually harm your health. An excerpt from the book published by the Guardian earlier this month was shared over 10,000 times and earned upwards of 700 comments – a mixed bag of supporters, skeptics and personally offended critics. Today, Offit has returned to the Guardian for a conversation with readers about the vitamin industry, alternative medicine and the placebo effect. We asked him a few things to get started but toss your own questions in the comments and Offit will respond today at 12pm ET | You need vitamins to convert food into energy. The question is how best to get them. Most people who eat a reasonable diet will get everything they need in the food that they eat. But there are some people who have special diets – for example vegans or those who live in climates where it’s never sunny – who would benefit from supplemental vitamins. But, for the most part, we get what we need in foods.
Other people think: “Because I’m not sure I’m getting all my vitamins, let me just take take a multivitamin every day” – which is OK. Multivitamins contain at or about the recommended dose of vitamins for that day. But then there are some people who believe that more is better – that by taking large quantities of daily vitamins they will do even better, live even longer and decrease the risk of cancer or heart disease. But in fact, many studies have shown that the exact opposite is true – that if you choose to take these large quantities of excess vitamins, then you increase risk of cancer and heart disease and shorten your life. Look at the root of the word: ‘Vita’ means life. I think people can’t imagine you could ever get too much of a good thing. But the second thing is that this industry is very good at projecting the idea that this product lives under an untouchable halo. It’s a matter of perception. If you go into a General Nutrition Center, you can get a preparation which contains 3,333% of the recommended daily allowance of Vitamin E.
In fact, that’s a typical Vitamin E preparation that’s available. If you open up the bottle and take out one capsule, you’ll find that it’s smaller than an almond. And, in fact, almonds are a good source of Vitamin E. One almond has about 2% of the recommended daily allowance. But to get to 33 times the daily recommended allowance, you would need to eat about 1,700 almonds – or about 17 pounds of almonds. And when you do things like this, when you take 33 times the recommended daily allowance of Vitamin E, you are messing around with mother nature. I think if people saw that one capsule as 1,700 almonds, they would be hesitant to take it. But they don’t see it that way. I think that in many ways alternative medicine lives in the realm of the placebo effect. When taking Vitamin C for a cold, you can learn to up-regulate your immune system – and you can learn to down-regulate your immune system. But you have to be careful not to take something that could also hurt you.
You know, we pop 1,000mg of Vitamin C when we have a cold without thinking. You would have to eat eight cantaloupes to get that quantity of Vitamin C – and Vitamin C can cause kidney stones and other problems. So I’d say don’t take vast excesses of vitamins, because that can be a problem. But our health is linked to both to the psychological and physiological, and psychological matters. I’ll give you a story about my daughter, because she’s the perfect example of this. She’s on crew – she rowed at the national level in high school. And when she rows she gets an occasional tingling in her fingers, and she was convinced by her fellow rowers that she has exercise-induced asthma – which she doesn’t have. She wanted a bronchodilator – which she wasn’t going to get – so instead, my wife took her down to the General Nutrition Center and they got something called a Himalayan sea-salt puffer. It’s just basically this salt which presumably came from the Himalayan mountains, and it’s put in this plastic canister at the top of which there are holes.
So you’re just breathing in salt. And my daughter thought this was great – she’s sitting at the breakfast table reading this box about Himalayan formations thousands of years old – and I say to her: “Honey, do you really think that the sodium chloride in this is going to be any different than the sodium chloride in that salt shaker?” She looks at me and says: “Will you let me believe in something, damnit?”If I say nothing instead of being a jerk like I was, she’d believe in this, and then it would help her relax – and that’s really her problem, she gets tense and she forgets to breathe. Now, she inhales this, remembers to breathe, she feels better, and she thinks it’s the salt. But even if it’s not the salt, that’s OK because it certainly isn’t hurting her. What, you’re saying people don’t like me? This is a belief system. When I ask someone to think about this, that’s threatening because belief I important. When my daughter says “Let me believe in something, damnit”, that’s it right there.
She’s saying “Don’t get all scientific on me, I need to believe in this.” She’s a little bit nicer than many commenters, but it’s basically the same response. You could reasonably argue, in a more rational world, that scientific issues are not elite issues of belief but are evidence-based issues subject to study. But belief is a part of this. In defence of my detractors, when I say “but look at the science”, what they’re saying is: “Let me keep my religion. Let me still be a member of the church of vitamins and supplements.” If there’s any ask in my book, that’s it. When you use the term “regulated”, that’s nice way to put it. It is essentially and practically an unregulated industry. In the US, you can put a dietary supplement or vitamin on the shelf and you don’t have to have data supporting your claims or data admitting your harms. One megavitamin study showed that if you take very large quantities of Vitamins A and E, you increase your chances of getting lung cancer.
Were the FDA to actually regulate this industry, I think megavitamins would have a black box warning on them. But they don’t – the consumer doesn’t know about many of the risks. There was one line I put in the book briefly. A few years ago, after two studies in one month that showed that showed how megavitamins hurt, there was a headline in the Wall Street Journal that asked “Is this the end of popping vitamins?” Buried in that article, there was a quote from a higher-up in the GNC corporation that said: “We just let these studies go. We ride them out. They don’t have any effect on our business, we were up 4.4% last year.” Until this industry is regulated, the consumer will always be uninformed.The industry is far too powerful. In the US, it’s a more than $30bn per year industry with lobbyists that spread money out on both sides of the aisle. Both parties have little incentive to go against them. Dr. Offit will be answering questions in the comments section relating to his new book and the excerpt featured on the Guardian.
