Should You Be Taking Vitamin Supplements?

In the past few decades, Americans have become much more aware of their overall health, and the factors that can improve or worsen it. With this, countless studies have been conducted to investigate the various ways one can improve their health. This phenomenon has led to tons of medical breakthroughs, forever improving the lives of humans across the globe. However, it has also led to things like fad diets and fad products, that can either do nothing for us, or make us worse off than we were before we tried them.

So which category do vitamin supplements fall under? Well, technically both. It depends on the supplement being taken and the current nutrient needs of the person taking it.

When Should Someone Be Taking a Supplement?

There are definitely times in life when taking a supplement is the best option for getting all the nutrients you need. But it’s important to differentiate between these times and the times when we probably don’t need to be taking one.

Pregnancy

One of the most prevalent times in life when a vitamin supplement is recommended is during pregnancy. Since this is a time of extreme growth in the woman’s and the baby’s body, there are severely increased nutrient needs. These needs must be met to ensure that the baby is developing properly and that the mother’s body is able to sustain the pregnancy. Specific nutrients of concern are folic acid and iron. Though it is technically possible to consume all the needed nutrients from foods during pregnancy, it is said to be very difficult because of the increased nutrient demand. Many mothers also report being too nauseous during the early stages of pregnancy to eat enough of the nutrient-dense foods required to do this. It is also recommended that women who may become pregnant consider taking a dietary supplement as well, so that their bodies are prepared to sustain a pregnancy.

Dietary Restrictions

Another situation in which you should consider taking a vitamin supplement is if you have a dietary restriction of some kind. Vegetarians and vegans can sometimes be at risk for Vitamin B-12 deficiency, since our primary source of this is meat. While there are still other foods that contain B-12, it may be difficult to get the amount our bodies need without eating meat. In this case, your doctor or dietitian may recommend that you take a supplement to prevent deficiency.

Lactose intolerance is another example of a dietary restriction that may require supplements. Specific nutrients of concern in this situation are calcium and Vitamin D, since these  are mainly obtained from dairy products. Just as with Vitamin B-12, Vitamin D and calcium can be found in other foods that do not contain lactose. However, it may be difficult for a person with lactose-intolerance to get the recommended amount. This is another case in which a doctor or dietitian may recommend a dietary supplement to prevent nutrient deficiency.

Older Adults

As we age, our bodies usually requires fewer calories. However, we still need roughly the same amount of vitamins and minerals to function. For this reason, it can be challenging for older adults to get all the nutrients they need. In addition to this, absorption of certain nutrients tend to decrease as we get older. Specific nutrients of concern are Vitamin B-12, Vitamin D, and calcium. The Dietary Guidelines for Americans recommends that older adults consider dietary supplements, specifically vitamin B-12 and vitamin D.

Medical Conditions  or Medications Affecting Absorption

Some medical conditions and certain medications can adversely affect nutrient absorption. This is another instance in which it’s probably best to take a supplement. Extra nutrient intake will ensure that your body is supplied with enough of the nutrients it needs and can properly absorb them. In this case, a doctor or dietitian should be the one to help you choose which ones to take that are best for you individual situation.

When Is a Supplement Probably Not Necessary?

If you are generally a healthy person who eats a balanced diet that looks similar to the MyPlate recommendations, then you really don’t need to be taking dietary supplements. (You’re more likely getting all the nutrients you need from food!) In fact, taking supplements may actually do you more harm then good. Too much of one vitamin or mineral can sometimes inhibit the absorption or storage of others. For instance, if someone’s zinc intake is too high, it will likely deplete the body’s copper stores, and sometimes also alter iron function. Likewise, excessive calcium intake has been associated with interference of iron and zinc absorption. The moral of the story is that you are more likely to get a healthy amount of nutrients from food, rather than from a vitamin supplement. When you take supplements, you risk potential of nutrient toxicity, which is practically impossible when only getting nutrients from food.

If you are generally a healthy person, but you don’t necessarily have the best diet, there are still other options to consider before taking a supplement. Look at the MyPlate recommendations and see what areas you can adjust your diet and lifestyle. You are better off getting your nutrients from foods, if you have the ability to. Only after you’ve exhausted all of your food options should you consider taking a supplement.

Other Things To Consider

Whether you take supplements or not, it’s important to educate yourself about regulations of these products. Though they are technically regulated by the FDA, supplements are technically considered to be “food” rather than “drugs.” Therefore, their quality and effects on the body are not assessed by the FDA. Only the supplement company themselves are responsible for evaluating this, which can cause obvious problems. Always do research and make sure you are aware of the effects of your supplements, beyond those that are listed on the bottle.

More than 50% of Americans take dietary supplements. But many of them don’t need to be. It’s important to always discuss supplementation with your doctor and/or dietitian. Getting an expert opinion can be really helpful and eye-opening. If you’re on the fence, I encourage you to try the “food first” policy.

  1. I love you idea of the “food first” policy and aiming to gain all your nutrients from your foods. That’s 100% what I aim for, and it’s truly the best, most natural, and probably most cost-effective route. 🙂

    There are two conditions under which I personally take supplements, beyond what you’ve mentioned. 1) When I start to feel sickness coming on. Olive leaf and oil of oregano have anti-viral, anti-bacterial, and anti-fungal properties to help fend off whatever’s going around. High doses of D3 also boost immune function, helping support the body’s defenses. They work like a charm! 2) There are some highly beneficial supplements that are harder to find naturally, such as lion’s mane mushroom for neurogenesis. With a history of dementia in my family, I want to bolster my brain as much as possible while I’m young to try to prevent future cognitive impairments.

    As you mention, talking to a doctor about these things is key! Out bodies are generally self-oiling machines, so we need to take care not to interfere with what they do naturally. Such an important article–thank you!!

    1. Of course! This article is by no means an all-encompassing assessment of supplements, rather just a compilation of the things I’ve learned so far. I think that the best way to go about taking supplements is to discuss it first with a doctor and/or dietitian.

      As far as your first example with olive leaf etc, my post wasn’t as much about herbal supplements as it was about vitamin supplements. Although I think it’s best to talk to a doctor/dietitian in that case as well. But herbal supplements are definitely something I want to learn more about!

      Thanks so much for taking the time to give your input and sharing your experience! And thanks for reading!

  2. This is a really interesting read so thank you for sharing. I currently taking a multivitamin and mineral supplement because as I am switching to a plant-based diet, I worry about keeping up my nutrient intake, but according to you, I only need to be taking B12 and possibly iron, calcium and vitamin D as well. I thought I was being responsible but perhaps not! xx

    1. If you’re on a plant-based diet, and not eating animal products, it’s definitely a good idea to think about taking a supplement. But just be careful that the supplements you’re taking don’t give you more than 100% of your daily value for that vitamin or mineral. You can usually check that information on the back of the bottle. Good luck!
