Yes, I have heard of vitamin D overdosing. When I doctor prescribes a vitamin D supplement, it should be with specific instructions regarding type, amount and length of time to take the supplement. The doctor should also be doing blood work regularly to find out how the body is responding and if vitamin D levels are returning to normal. Then the appropriate follow up treatment can be determined. Going a year and not check the levels is dangerous for someone who is using vitamin D supplementation for low vitamin D stores.

My doctor had me taking Vitamin D supplements for over a year. Doctor's office called me yesterday and told me the blood work I had done last Friday showed an overdose of Vitamin D. It was also in my Multi Vitamins and added to the orange juice I was drinking. I have been very tired lately and now that I stopped taking Vitamin D I hope that will change as I read that was one symptom of too much Vitamin D. Couldn't find much other information searching the web. Anyone have any experience in this?

I'm not familiar with the metabolism and storage of Vitamin A from food sources. I know, on a supplemental basis, that we should be cautious about the lipid-soluble vitamins (A, D, E, K) because, unlike the others, those can build up and may become troublesome.
When you talk to your doctor about the calcium, also bring up the topic of Vitamin K2 in combination if you're using a supplemental form of calcium. From things I've read, K2 helps to get the calcium out of your bloodstream and into your tissues. Your doctor should be able to give you the best info on what kinds of supplements (if any) would be healthy for you.

Thank you for your input and reassurance. I won't worry about the vitamin A surplus. Yes, I will talk to my doctor about calcium supplements. I suspect there is something in the supplements/fortified foods I've tried so far that I react to.
The vitamin A in the veggies and fruits is beta-carotene. This is converted to active vitamin A as needed by the body. So you do not need to worry about overdosing on the form found in produce. I think you are fine. Usually over-dosing is an issue only with people who take excessive amounts of supplements or eat very large amounts of liver "everyday".
I imagine you will have difficulty reaching your calcium intake recommendations, based on what you are sharing. You may want to talk to your doctor about a supplement.

Thank you for the link and reassurance. If only I could learn to love tofu.. It seems like I should worry more over my lack of calcium than the abundance of vitamin A in my diet. Perhaps I would be better off limiting the herring and mackerel rather than the carrots ;)

I just tracked several micro-nutrients and discovered I am consistently very high on vitamin A. Should I be concerned about this? I have raw carrots more or less daily, often several servings a day, and I eat fish often.
I also discovered I am consistently low on calcium. (I am allergic to all dairy.) Even on the days where I ate broccoli, sesame seeds or pickled herring I did not meet the bottom suggested range. Are there any other naturally calcium rich foods that will provide enough calcium when eaten in normal amounts? Most calcium supplements will make me feel sick, including fortified soy-milk.
