Are These Vitamin Levels Normal?

B12=1328 it was 570 and then i started taking sublingual 2500mcg b12 supp (my doctor said to quit taking the supplement because it was high now.)

Vitamin D=34

Magnesiun= 1.9mg

I don't know about the magnesium. But your vitamin D is too low, it should be at least 50 to 150, around 125 being optimal.

The best way to get vitamin D is in cod liver oil. Try the Carlson brand, it doesn't taste bad (that is what I am taking).

Are you referring to 50-150nmol/l or ng/l

My doctor said sufficient vitamin d is between 32-100ng/L. Is it dangerous to take supplements in case of toxicity. Do the cod liver pills work good, and what size dose?

Optimal 25-hydroxyvitamin D values are:

45-50 ng/ml or

115-128 nmol/l

Normal 25-hydroxyvitamin D lab values are:

20-56 ng/ml

50-140 nmol/l

Taken from mercola.com

So, if your doctor says that 32-100ng/L is normal, then he is saying that toxic levels are normal. I guess I was thinking you meant nmol/l, which is what I was referring to.

Still, even if your lab measures by ng/L, 34 is normal, but not optimal.

I find using the liquid Carlson's cod liver oil is best, because those pills don't contain much. Plus, I hate taking pills. In your case I would suggest taking one teaspoonful a day, and having your levels checked again in a couple of months. Because vitamin D toxicity is dangerous, too.
