Most people don't need to take vitamin supplements and can get all the vitamins and minerals they need if they eat a healthy, balanced diet. However, if you're not meeting the recommended daily amount of vitamins and minerals, taking a multivitamin can be an effective and safe way to make up the difference. It's essential to consult with your healthcare provider about the dietary supplements you take regularly, particularly if you have a health condition, dietary restriction, or are taking any type of medication. Even if none of the supplements individually surpasses the maximum limit for a given nutrient, combining several pills, such as a multivitamin and an additional vitamin D capsule, for example, can result in higher doses than recommended.
While taking a daily multivitamin is generally safe, consuming more than the suggested amount of certain vitamins and minerals can be dangerous. That said, a multivitamin can help make up for some deficiencies in a person's diet, particularly if they avoid certain food groups such as meat or dairy products. As an expert in nutrition and dietary supplements, I recommend that you speak with your healthcare provider before taking any type of supplement. They can help you decide which supplements are suitable for you and how much of each supplement you should take.
Additionally, they can assist you in understanding the potential risks associated with taking too much of any one vitamin or mineral.
