How long do you guys wait inbetween your vitamins?

I have to take a synthroid upon waking, and then I have 4 calcium tablets that I take 2 at a time during the day. I have a multi vitamin, a sublingual b12 and now I have to add iron. How much time do I need to give inbetween my doses? I have to wait 60 minutes after the synthroid. Debbie -61.5

Debbie, I take my calcium in AM and at bedtime but on the iron do not take it with calcium they will cancell each other out so best to take iron mid-day I know it should be 1-2 hours between iron and calcium. I usually take the multi mid-day since it has some iron in it. I take the B-12 shots much cheaper and only have to do once a month. The Dr gave me a prescription for a vial with about a years worth or more in it and cost less than $10. Hope this helps, Nancy

Debbie, My dietician recommended that I take everything (multi, b-12, iron, c, zinc) in the morning and the calcium later in the afternoon. I use the calcium chews from GNC and I take two each afternoon, but I wait at least an hour in between each calcium.
