While multivitamins are always trending, it's important to know what they are exactly and how we can include them in our diet ( and if we need any at all).
In the face of an increasingly crowded market of multivitamin supplements, I had to conduct extensive research to find out how to determine if they were worth buying.
Let's dive right in.
- Multivitamins can be described as supplements that combine different minerals and vitamins, and are available for use.
- Iron, magnesium, calcium, zinc, Vitamin C, Vitamin E, vitamin K2, Vitamin A, Vitamin B1, Vitamin D2, and Vitamin B3 are some nutrients found in multivitamins supplements.
- Multivitamins increase nutrition intake, prevent chronic diseases, improve brain function, and improve mood.
What Are Multivitamins (And What Do They Contain)?
Multivitamins are supplements that combine multiple vitamins and minerals, sometimes alongside other ingredients. In the United States, people often search and browse for information about vitamin D, folic acid, and other vitamins like vitamin A when learning about the benefits, usage, and side effects of multivitamins.
There are many multivitamins available on the market.
These vitamins are not strictly regulated by the Food and Drug Administration (FDA). As a result, there is no universal standard, and the nutrient components you're looking for in a multivitamin can vary by brand and product.
Most multivitamins contain:
Additionally, certain multivitamins also contain some herbal ingredients or nutrients such as friendly bacteria, amino acids, fatty acids, or ginseng.
Health Benefits Of Taking Multivitamins
The benefits of taking multivitamins compared to single individual vitamins include:
Increased Nutrition Intake
Some people cannot or do not meet their needs from food due to poor nutrition or some medical conditions. Taking multivitamins can help fill these nutritional gaps .
Chronic Disease Prevention
The evidence concerning multivitamins and chronic diseases is pretty mixed.
Although most research shows that taking vitamins and minerals can impact our overall health, they mostly agree that it is not directly linked to reducing the risk of developing chronic diseases such as cancer or disease of heart.
A review including 47,289 participants separated into five randomized controlled trials concluded that the risk of cancer in men who took multivitamins was 31% lower, but had no effect on women .
Multivitamins may help improve brain function, mood, and memory (especially for older adults) .
Many studies serve as scientific evidence of a link between nutrition deficiency and lousy mood.
In addition, antioxidant vitamins and minerals may help slow the progression of certain diseases that cause blindness .

“Millions of Americans today are taking dietary supplements, practicing yoga, and integrating other natural therapies into their lives. These are all preventive measures that will keep them out of the doctor's office and drive down the costs of treating serious problems like heart disease and diabetes.”

Can Multivitamins Be Harmful?
Some vitamins can cause serious side effects if taken in high doses; therefore, combining these with your daily multivitamin should be avoided .
Also, keep in mind that exceeding 100% of the daily value of some dietary supplements is not helpful. Excessive intakes of certain nutrients – like zinc, niacin, folic acid, or vitamins A, D, E, and K – can become toxic .
Pregnant women should be especially cautious with vitamin A intake since it's proven to raise the risk of certain birth defects in their babies .
Large intakes of beta carotene and vitamin A have proven to raise the risk of lung cancer. Therefore, smokers should avoid multivitamins containing large doses of any of these .
Another risk is consuming too much iron, which could impact the body's ability to absorb zinc .
Be careful with taking multivitamin products with an already nutrition-dense diet since it can lead to exceeding your recommended daily intake.
Who Should Take Multivitamins?
As we all know, certain vitamins are essential for our health .
Even though you can get most of these vitamins from a well-balanced diet, for some people, it may be tricky to get enough nutrition in certain circumstances.
This is where multivitamins can quickly fill up these small but critical nutritional gaps in the diet, helping prevent the symptoms of low intakes
These circumstances include :
- Age – our bodies find it harder to absorb some essential nutrients as we get older
- Allergies or intolerances – difficulty to absorb certain nutrients
- Vegetarianism and veganism – these diets could be missing certain nutrients that are mainly found in animal products
- Pregnancy and breast-feeding – pregnancy increases your body's need for certain nutrients, such as iron and folate
Taking multivitamins with other medications or dietary supplements can cause drug interactions or affect how medicines work in your body. Ask a doctor to provide medical advice if it is safe to use multivitamins if you are on any other medication.
What Happens if I Overdose on Multivitamins?
If you overdose on multivitamins, the side effects can lead to severe complications and, in rare circumstances, even death . These side effects include headaches, nausea, stomach cramps, diarrhea, and vomiting.
Do Multivitamins Cause Weight Gain?
Multivitamins don't make you gain weight, as they hardly include any calories. On the other hand, multivitamins containing B complex may increase the appetite and trigger obesity .
How Would You Increase Vitamin Intake?
In the United States, people often turn to folic acid, B complex, vitamins A, and vitamin D supplements as they explore the benefits, usage, and potential side effects of multivitamins.
