Confused about what vitamins to take: Which supplements should I be taking to be healthy?

Jennifer came into the office for a routine check up. She was a generally healthy 45 year old who was starting to try to start taking better care of herself after years of caring for the other members of her family. She had great intentions to start exercising, was hopeful to improve her diet and lose weight. She was getting caught up on all of her health screening such as mammograms. She felt healthy but was frustrated with the weight she had gained since having kids. She was “tired all the time” but felt this was normal given her busy schedule.

During the course of our visit Jennifer asked the inevitable question “What vitamins should I be taking? My friends keep telling me to take different things and I keep thinking that if I keep a healthy diet I don’t need to take anything. My mother sent me this article from the New York Times saying many multivitamins are not good and I am so confused!” This is a common problem we hear from our patients. They feel confused by all the conflicting information they hear from the media, friends, neighbors and relatives.

As physicians, we know that there is in fact an important role for vitamins in health. However, much of the confusion and conflicting messages stem from the fact that we are not all the same. We all have different diets, lifestyles and health concerns. Why would it make sense that we take the same vitamins? When the New York Times or the US Preventive Services Task Force make blanket claims about vitamins they are often looking at one size fits all answers. The truth is a bit more nuanced.  It often takes a trained medical professional to help sort through all of this confusing information. We are here to help!

It turns out that there is lots of valid research supporting the use of certain vitamins for certain people in certain amounts. There is not as much evidence to suggest that a generic off the shelf multivitamin has great benefits for whole populations. However, specific examples include Vitamin D, which has great data supporting its benefits in improving mortality, reducing fractures and helping certain problems such as migraine and muscle aches. Most of the population is Vitamin D deficient if they do not take a supplement. Iron is useful for many people who don’t get enough via diet (vegetarians, vegans) or those who suffer from deficiency because of heavy periods, GI absorptions issues (such as celiac, inflammatory bowel and more) and thinning hair. Many people need supplemental B vitamins, magnesium, and iodine due to lack of these vitamins in the food supply. Thus, specific vitamins are very important in certain people depending on what they eat, who they are, and what symptoms they experience.

Yet, the opposite is also true. There are many vitamins shown to cause harm. For example taking supplemental Vitamin A has been associated with cancer and osteoporosis. Vitamin E in high doses has been shown to cause harm. Taking too much vitamin D also can cause kidney stones, mental status changes and more. Taking the wrong vitamin doses of even helpful vitamins can be dangerous. No wonder Jennifer was confused!

In her case, a conversation about her diet and health habits made clear that her efforts to be healthy meant she was no longer eating red meat and was severely lacking in iron. She was vitamin D deficient and also was in need of additional B12, magnesium, and iodine to support her thyroid. The correct combination of vitamins led to her improving her energy, ability to exercise and ultimately helped her to lose the pounds she had hoped to lose.

There is great scientific data to prove that some vitamins have benefits. But who needs which vitamins and what amounts are the more challenging questions. It is for this reason that, as physicians, we conceived of Vous Vitamin. We created a venue where people can take a brief online survey(take our personalized vitamin quiz) about themselves, their diet, lifestyle and health concerns to get the exact vitamins to meet their individual needs. Not too much, not too little. A personalized multivitamin is a simple one pill solution that helps our customers get a doctor created, medically sound and high quality product to meet their needs. Almost everybody can benefit from adding the right vitamins to their routine. Knowing which ones are needed and in what doses is the key.
