What are multivitamins? 

Multivitamins, by definition, are a supplement that contains more than one vitamin within the same product. Typically, multivitamins are pills or capsules, but now they are also available in liquid forms, powered forms, and even candy-like gummy forms, which make them much easier to remember to take. They’ve been available since the 1940s and have steadily grown in popularity.1 

Multivitamins were designed to make up for any deficiencies in your diet. It can be difficult to hit your goals for fruits, vegetables, and whole grains every single day, so the multivitamin was designed to ensure you got adequate amounts of the vitamins your body needs, consistently. 

 

There are three primary types of multivitamins on the market today: 

1. Broad spectrum, or once-daily multivitamins 

These are designed to be taken daily regardless of specific nutrient needs or diet restrictions. They typically contain close to the recommended daily amount of each vitamin and mineral included.

 

2. High Potency or Mega Multivitamins 

These types of multivitamins typically contain much more than 100% of the recommended daily amount of some vitamins and minerals, e.g., maybe 400% your recommended Vitamin A, C, and E. These are designed for people who want to boost a specific nutrient quickly and may contain other supplements or minerals. 

Often, taking much more than needed means your body just gets rid of the extra amounts, but extremely high levels of some vitamins and minerals can be dangerous.

 

3. Specialized or Targeted Multivitamins 

These types of multivitamins are classified based on the goal they claim to support – like weight control, energy boosts, immunity, or hormone balancing. They often have high levels of a combination of vitamins, minerals, and other supplements like green tea extract or amino acids. 

 

What are the benefits? 

The benefits of multivitamins, as they were designed, is for those who need a boost in a specific nutrient that they aren’t able to obtain from their diet.  

Taken regularly, a multivitamin can help both prevent vitamin deficiencies and potentially treat current deficiencies to bring your levels back to the optimal state.  

 

When might you need multivitamins? 

Based on your stage of life, medical conditions, dietary habits and other factors, there are many reasons why you might need a multivitamin to stay healthy. Consider the factors below to determine if you might benefit from a multivitamin. 

 

If you are pregnant 

When you are pregnant, your body is creating another human that needs all of the same (and even more of some) vitamins and minerals that your body needs. During pregnancy, folic acid and healthy fats are extremely important for your baby’s development, and you might benefit from some extra iron and B12 based on your blood levels. Luckily, there are many different multivitamins on the market – most doctors recommend taking them before you become pregnant and possibly even after you deliver if you plan to breastfeed. 

 

As you age 

Our bodies become less efficient at absorbing vitamins and minerals from our food as we age, especially Vitamins D and B12. Often these “senior” vitamins also contain calcium to support healthy bones, very important as we get older. 

 

Allergies 

If you have food allergies that prevent you from consuming entire food groups (like dairy or wheat), you may benefit from a multivitamin. Many dairy-alternatives also contain calcium (one of the primary nutrients most get from dairy products), but in different levels. 

If you avoid all wheat products you might be missing many of the B vitamins in your diet, so could benefit from supplementing with a multivitamin. 

 

Other Diet Restrictions 

If you choose to follow a vegan or vegetarian diet, your diet is likely low in some nutrients that are found at high levels in meat and animal products, like iron and B12. 

Also, if you have to follow a low fibre diet, a regular multivitamin would definitely be beneficial. 

 

Medical Conditions 

If you have any medical conditions, speak with your doctor about any potential concerns and they can check your blood levels to help you identify what types of multivitamins would be the most beneficial.

 

 

How to choose the best multivitamin for you 

Gender makes a difference 

Men and women are built differently – women are more prone to osteoporosis and need additional calcium while men are less likely to need additional iron. You might be able to choose a multivitamin geared toward your gender, but you can also check the labels to make sure any nutrients of concern are adequate while you’re shopping around. 

 

Age counts 

Our body’s needs change over time – we need some vitamins in higher levels as children and others as adults. 

While Vitamins D and B12 are more important as you age, school aged children and young adults may benefit from more Vitamin C and zinc to prevent colds that spread easily amongst their friends. 

 

Consider your goal 

Work with your doctor or registered dietitian to examine your eating habits and select a vitamin truly based on what your body needs. 

If you’re trying to lose weight, make sure your diet is still nutritionally adequate – and make up for it if it’s been lacking. B Vitamins and D vitamins can support your energy. If you’re getting sick all of the time, maybe you need a multivitamin focused on immune support. Are you studying for an important exam? Try finding a multivitamin that supports brain health. 

The important thing is to work with your doctor to find exactly what will be most beneficial to you.
