Computer programmer - 8-10 hrs/day, don't go out in the sun

Past history
Following a low carb vegan diet 2-3 years (no dairy sources in the diet)

Seizure around age 9-10

Symptoms
obvious - muscle weakness, osteopenia
subtle/occasional - memory problems, general weakness, anxiety, problems passing urine(no urine problems currently)

1st blood test (from Lab company A)

Next day (From lab company A)
Calcium ionized 4.8 mgm/dl (4.0 - 4.8 mgm/dl)
serum magnesium 1.8 (1.70 - 2.70)

I think after 1st blood test I took 2 small vitamin D supplements
which had 200 IU units in each and calcium citrate of 1000 mg.
I took it even before I got the lab results.

I had an 4-5 month old liver function test report which had
Alkaline phosphate 136 units/l (39-117)

2nd Blood test the very next day (From lab company A which outsourced my blood to company B)

PTH, intact 150 (10-65) pg/ml

Endo doctor said Lab A and B might be wrong, so let's check it again after 1 week.
