Medical experts say most of us, even those north of 70, don’t need to be taking multivitamins. If w eat a well-balanced diet with fruits, veggies, proteins, dairy, and whole grains, we should be getting all the vitamins and minerals we need, despite what that YouTube video told you.
You should be getting a yearly physical from your primary care physician. If any vitamin deficiencies show up, let your doctor tell you and prescribe the right amount to take.
Multivitamins probably won’t hurt you, but it’s money wasted.
