Listen to Dr. Neal address this topic on Episode 150 and Episode 755 of the podcast Optimal Health Daily.

There seems to be so much conflicting data with regards to taking vitamins or supplements. It seems like scientists, doctors, and dietitians or nutritionists cannot come to a decision on whether taking them will help at all. Plus, if you do decide to take a vitamin or supplement, you may not know whether they are free of contaminants or actually contain the nutrients they’re supposed to and at the right dosage. I believe I’ve said this before, but I’ll say it here again: the supplement industry right now is similar to the Wild West… it’s every person for themselves. We as consumers have to do our research and make sure we are not causing more harm than good.

Should You Take Daily Vitamins and Supplements?

Here is the “no B.S.” answer: most people do not need to take any vitamins or supplements. You may not have liked that I said “most people,” but it’s important I make this distinction. What I mean here is that most healthy adults do not need to take a multivitamin every day, or extra vitamin C, or zinc, or calcium, or a sports supplement, and so on. There have been a number of published studies looking at whether supplementing with vitamins and minerals can prevent disease and prolong your life. It turns out they don’t seem to help with either one. Instead, getting your vitamins and minerals from eating real foods that have been minimally processed is best. This is because our bodies are better equipped to extract the nutrients from whole foods as opposed to supplements. If you think about it, many supplements contain weird combinations of nutrients–combinations you wouldn’t find in nature. The body gets confused and is unsure of how to process these weird combinations of nutrients. Because it doesn’t know what to do, the body gets rid of them. For many of us, when we take these supplements, we just end up with nutrient-rich urine.

There’s also the risk of toxicity. This usually happens when people take it upon themselves to supplement with minerals like iron, magnesium, or zinc. Plus, there are those vitamins and minerals that we know increase disease risk when we supplement with them. Vitamin E and conjugated linoleic acid (CLA) come to mind.

All that said, taking a multivitamin is like having an insurance policy. It likely won’t hurt, but may help if under certain conditions. Here’s why: in industrialized countries like ours, the abundance of food has prevented many of the common nutrient deficiencies that used to be so common. The risk for developing a vitamin or mineral deficiency is pretty low. But we know that even with all of this abundancy, we may not select those most nutritious foods.

Who Should Take Vitamin and Mineral Supplements

Many of us have access to fresh fruits and vegetables, but we also have access to lots of fast food and sit-down restaurant options. Not that everything found in your local supermarket is the most nutritious, either. That’s why so many health professionals, including me, say that when you are grocery shopping, it’s best purchase nutrient-dense foods. These would be

  • fruits and vegetables
  • whole grains
  • fish
  • nuts
  • legumes
  • seeds

Vegetarians & Vegans

I’ll give you an example. I’ve had excited patients tell me that they have switched to a vegetarian lifestyle.

I’ll respond, “Ok, so tell me about what you’ve been eating.”

And they’ll say, “Oh, you’ll be so proud of me… for breakfast, I will eat a bowl of oatmeal with a whole grain English muffin on the side. For lunch, I will have a peanut butter and banana sandwich on whole grain bread. And for dinner, whole wheat pasta topped with marinara sauce and a whole wheat roll on the side!”

Uh… did you notice what happened to be missing from this meal plan?? Vegetables! This isn’t a vegetarian diet, it’s a carb-a-tarian diet. Vegetarian diets actually require the consumption of vegetables.

In this case, I would be concerned that the person isn’t consuming enough nutrients to support optimal health. In addition to trying to get them to consume more vegetables and other fruits besides just bananas, I would recommend they think about taking a multivitamin to prevent any vitamin and mineral deficiencies.

If someone isn’t consuming a well-planned, balanced diet, I may recommend they speak to their doctor about taking a multivitamin. But, there are other folks that may want to consider this, too.

Those that follow a vegan lifestyle may want to consider a multivitamin, too, at the very least, a vitamin B12 supplement and possibly an omega-3 supplement. This is because the form of vitamin B12 the body needs only comes from animal products. Furthermore, the type of omega-3 fats found in cold water, fatty fish are different than the types found in plant-based foods like flaxseeds and walnuts.

Others Who May Benefit From a Daily Multivitamin

Iron Deficiency

Young men and women are often iron deficient. On top of that, during adolescence, they may not follow the healthiest eating patterns. In fact, if they are anything like me when I was an adolescent, breakfast and lunches are skipped and fast food is the dinner of choice. It’s possible that they are missing out on other important nutrients. During this stage of development, rapid growth is taking place so it’s important that the body has everything it needs to support this. Therefore, pediatricians may recommend that some younger folks take a multivitamin.

Older People

As we get older, we find that we aren’t able to digest and absorb nutrients as well as we did when we are younger. Plus, we’re more likely to have issues with our teeth and taste buds, which influences which foods we prefer, and making our food choices much more limited. We’re also more at-risk for developing chronic conditions like osteoporosis. Here again, it may be helpful to consume a multivitamin, particularly one that is specially formulated for older adults.

Those With Digestive Issues

Some folks may suffer from digestive issues like Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (like Crohn’s disease and ulcerative colitis). These individuals may benefit from supplementing with specific nutrients like folic acid, magnesium, and probiotics.

And More

  • Those with eating disorders, like anorexia or bulimia
  • Folks that suffer from anemia
  • Menopausal women
  • Folks that rarely consume fruits or vegetables
  • Marathon runners or athletes that perform high intensity physical activity on a regular basis
  • Those that suffer from alcoholism or those that regularly smoke cigarettes

There are certain situations where a doctor or a dietitian/nutritionist may recommend a supplement. But often times, they don’t recommend you start taking a multivitamin – they’ll recommend a specific supplement for a specific condition. For example, those that regularly smoke cigarettes should take a vitamin C supplement. Vitamin C can help offset some of the damage caused by smoking. Marathon runners or those that perform regular high intensity physical activity should also consider taking a vitamin C supplement.

You are probably wondering if I take any supplements. Because most of my workouts last at least an hour and incorporate high intensity training, I take a vitamin C supplement every day. But that’s it.

Finding the Best Vitamin and Mineral Supplements

Whatever you and your doctor decide, just keep in mind that some of the vitamins and minerals you get in pill form may not always be absorbed. There are a number of reasons for this.

First, our bodies are better equipped to pull nutrients from food instead of a pill.

Second, the way the supplements are manufactured affects how the body absorbs them. Some vitamins are immediately destroyed when they hit the stomach because of the stomach’s strong acid content. Others are better absorbed when you take them with food. For example, calcium is often found in 2 forms when you buy it as a supplement: calcium citrate and calcium carbonate. Calcium carbonate, specifically, is better absorbed when taken with food. Oh, and calcium is better absorbed when some vitamin D is present, too.

Tips When Buying a Supplement

If you and your health care practitioner decide you should take a supplement, please take a moment to research the various brands to be sure you are buying a quality product. One of the most complete resources I have ever seen with regards to supplement safety is Consumerlab.com. They are an independent company, which means they don’t get paid by any supplement manufacturers, and they randomly test supplements for quality and purity. They will even tell you where to find the cheapest ones. Consumer lab is not a free site, but it's very affordable, and if you're a student, you may find that your school is actually paying for access to their database. Definitely ask your librarian!

Also:

  • Ignore misleading claims – sadly, misleading claims on the packaging of nutritional supplements can still happen. If a supplement promises to be a cure for something, ignore it and definitely don’t buy it
  • Take a look at the form the supplement is in – omega-3 supplements should be “enteric-coated” which helps prevent it from being absorbed too quickly. Also, don’t buy chewable vitamin C because vitamin C is an acid (ascorbic acid) and this acid can eat away (pun intended) your tooth enamel.
  • Do your homework and check for quality and purity! Look for an ISF or USP symbol on the packaging. Or, check out the aforementioned ConsumerLab.com and do a quick search on their website.

Conclusion

Taking a multivitamin daily probably won’t hurt you–it’s possible that it may help. But of course, talk to your doctor to be sure that it’s right for you and if there are other specific supplements they would prefer you take along with it or instead.
