Daily Dose of Vitamins?

Hi I was just wondering if it is safe to take two mulivitamins daily? I also have been taking two calcium supplements at the same time, about 600 mg each. They have vitamin D as well. I've read that calcium should be taken at different times in the day. I'm just not sure how far apart to take them. I have hypothyroidism and am on medication for that, which means I cannot take any calcium or other vitamin supplements until about four hours after. Also are there any other vitamins that could help me with my energy? Thanks.

If the 2 multi-vitamins combined do not go over the 100% of the recommend daily dose, then that will be fine. Calcium supplement should be taken with food so you maximize the absorption of the calcium with the stomach acid production of food in the stomach. Eating properly would help your energy levels. Suggest eating 5-6 small meals throughout the day which will help you.
