Supplementing food with vitamins won't be advantageous for everyone. Different vitamins contain varying amounts of nutrients, some of which can be harmful if ingested in excess. Always evaluate any supplements you intend to take with a healthcare professional. Eat a nutritious, well-balanced diet: If you consume a wide range of nutrients from fruit, vegetables, lean meats, eggs, nuts, seeds, beans, low-fat dairy products, and fish, you are probably getting all the nutrients you need and may not require supplements.
Consider taking a multivitamin or a single vitamin. If you are already taking a multivitamin or a single vitamin, talk to your doctor before adding a new one. Multiple dietary supplement usage can lead to vitamin toxicity and have detrimental consequences on one's health.
