I started Vitamin D supplementation at the beginning of this year and have
noticed a big improvement in mood. I am now taking 4,000 IU a day. My blood
calcium level has remained the same, but my blood CO2 level has risen from
22 mmol/L to 33 (lab says normal range is 20-32). I didn't think much of it,
but a friend has just reported the same results with the same regimen. Can
Vitamin D raise CO2 levels, or is this a coincidence?

COMMENT:

Coincidence with the vitamin D. But not coincidence that the "total
CO2" level rises with each draw. This is very common as people get less
anxious about blood draws over time. The first time they
hyperventilate and pCO2 (what you meansure on an ABG) and total CO2
(mostly bicarbonate, what you measure in a blood draw), are often low.

Interesting... so, Bob, do you remember being more anxious the first
time you had your blood drawn?

I have been taking 4,000 IU to 6,000 IU of Vitamin D for the last few
years and have also noticed that my bicarbonate is also slightly above
normal on the last three blood tests. I never made the connection to
vitamin D though. Some of my friends are starting to take the higher
dosage too so I will have them track the bicarbonate levels on their
blood tests. Thanks, Bob.
