It is generally good for teens to take a multivitamin – for example, the iron in multivitamins can be beneficial for growing adolescents and for females who are menstruating. However, FX does not recommend taking more than one multi-vitamin per day. For one thing, there are certain vitamins, such as A, D, and E which can be toxic if too much is taken. Second, if you eat a healthy diet (which obviously FX recommends) you shouldn’t need more vitamin supplements than what is in one multi-vitamin. And in your case, there could be many reasons why you may be feeling fatigued – doubling or tripling up on a vitamin is not going to be the answer.
There are many physical and emotional health issues that can contribute to fatigue. Fatigue can be caused by physical illnesses, such as a virus. It can be caused by mental health issues, such as depression or stress. It can also be caused by lifestyle factors – people who don’t eat well, are not very physically active, or don’t get enough sleep. Simply increasing the amount of vitamins isn’t going to effectively and totally deal with these kinds of issues.
TeenHealthFX recommends you meet with your doctor to discuss the fatigue you have been feeling – so he/she can determine what is contributing to how tired you have been feeling and can come up with an effective treatment plan to address those issues. It would probably be fine for you to continue with one, and only one, multi-vitamin a day – but check with your doctor about this as well so he/she can guide you on the best type of vitamin for you to be taking.
