Yeas, that's what I meant. Each Ca supplement (Citracal, Caltrate) has 400
IU and 600 mg Ca. I take 2 tabs/day in addition to fortified milk in cereal
and a cup of yoghurt and some raw broccoli.

Is that too much Vit D ? What if I add a multivitamin tab (which has 400
IU )?

By the way, in a recent Metabolic Panel blood test, I had 9.2 mg/dL of Ca,
which is in the normal range (8.5 - 10.5 mg/dL). Does that mean that my
diet (vis a vis Ca and Vit D) is adequate?

If so, would that point to androgen deficiency or hyperparathyroidism?

That would make 1200 IU (= 30 mcg). I don't think that is too much, but it
depends on also on your location, on your sun exposure in summertime, ethnic
origin (skin tone) etc. If you have Indian origins (as I suspect from your
name) and you live at higher latitudes you might need even more than 1200
IU.

Personally I take 40-50 mcg (1600-2000 IU) in agreement with my doctor.
However, I live at latitude 60 N.

But as I wrote before, I suggest that you have your calcidiol [25(OH)D]
levels assessed because that is the only correct way to determine the
optimal dosage of vitamin D. This test is best to take at the time of year
when your calcidiol levels are the lowest (usually in February/March).

Also make sure that the supplements you use, are vitamin D3
(cholecalciferol). Vitamin D2 (ergocalciferol) has only 1/3 of the efficacy
of vitamin D3.

I can not answer these questions, I suggest that you discuss with your
doctor.

Since calcitriol is the active form in your body, wouldn't you want to
measure the calcitriol level. That's what you really want to make sure
is in the expected range...Best wishes and good health, ron

No. Calcidiol, 25(OH)D, is the correct test to use in determining the
circulating vitamin D levels. There are several studies which state this.

IMHO, calcitriol is measured only if there is a reason to suspect kidney
disease, as it is the job of kidneys to try to keep the calcitriol levels
constant.
