Questions people ask about multivitamin

Multivitamin vs Omega-3: Do You Need Both?Mostly, but carefully check your multivitamin label. Many already contain Vitamin D, which can lead to stacking if you take a separate D supplement. Omega-3 is less likely to be duplicated.
Multivitamin vs Iron: Do You Need Both?Taking a separate iron supplement with a multivitamin can lead to excess iron, which is harmful. Check your multivitamin's label first.
Multivitamin vs B-Complex: Which Is Better?Most multivitamins contain a B-complex, making a separate B-complex redundant. Check labels to avoid exceeding B6 or B3 upper limits.
