I am regularly taking multivitamins.  Maybe they are not the best multivitamins,  but they help me a lot in my daily activities.  My husband bought them for me after he noticed me sleeping more than ten hours a day.  From that time onward, I don’t feel tired all the time like before and I feel a lot more energetic and awake.  I think my sleeping disorder must have been due to a lack of certain vitamins and minerals.
