Bloodwork Results Calcium and Vitamin D Question

[Windex]

Went for bloodwork as an MRI revealed I may have some bone problems plus I have a family history of Osteoporosis (Mother, Grandmother, Great Grandmother, etc).

Calcium Reference 2.15 - 2.60 mmol/L
Result : 3.66

25-Hydroxyvitamin D Reference 75-250 nmol/L
Result: 40

So my Calcium is sky high but my Vitamin D is tanked. Started taking 2000IU/day (2x1000IU) of Vitamin D as per my doctor. My question is why are these two opposite? I always understood that Calcium and Vitamin D go hand in hand. Google was not helpful >.<

I got a bone density scan done on Friday but won't know the results for another week.

On the same bloodwork panel I also got tested:

Erthrocyte Sedimentation Rate, Reference = 2-30 mm/hr, Result = 6
Alkaline Phosphatase, Reference = 40-129 U/L ; Result = 72
Magnesium Reference 0.70-1.00 mmol/L, Result 0.88 (Side Question: should I take a Magnesium supplement, ZMA, or neither?)

Thanks in advance for any insight !

Is this your first calcium test? If so, it's always worth double checking it. Did your doc discuss the possibility of hyperparathyroidism, which is a common cause of elevated calcium levels? Obviously there are other causes but that's a very prevelant one.

Remember to take your Vit D with a large meal as well as it's fat soluble. I don't think 2K iu's will take you up that far but it's a start. It also absorbs better when taken with Vit C. I'd say no to extra magnesium right now. No need to throw to many wrenches just yet.

Good to know about a meal. I am taking it with Vitamin C. She hasn't discussed anything yet as I don't have my follow up appointment for a couple weeks but will make a note.

Thanks for help !!

Yeah, be careful with high calcium in blood. Also if its in your blood its not in the bones where it should be.

High blood calcium can also possibly result from dehydration (chronic).

As for magnesium long-term supplementation has been shown to be effective in osteopenia and osteoporosis prevention and treatment, the bone serves as a reservoir of several minerals essential for life not just calcium, when diet is deficient in any of these bone breakdown will occur so that to preserve homeostasis, and Mg appears to be the most deficient minerals in modern diet, so...

Thanks for the help. Next Doctor appointment is next week - I'll bring up the magnesium and see when I can get another Calcium + Vitamin D Test
