IMO almost all multivitamins are poorly designed. Tons of iron, calcium, niacin, and folate that we don't need and not enough (or poorly formulated) magnesium, potassium, iodine, etc. In population studies multivitamins don't have much effect even though individual supplements do.
The most important deficiencies to consider are the non-food ones: D3 and magnesium (historically came from drinking water). If you have a good diet, spend your noon hour outdoors, and take an occasional epsom bath you're good to go. If you live in a high latitude then D3 with lunch during the cloudy months may be wise. My apartment doesn't have a bath so I take 200mg magnesium glycinate with dinner.
