help with OTC vitamin D side effects

[Guest guest]

Hi everyone!

I have a client who is coming to me with questions about side effects she's

had when trying to supplement with vitamin D. Her

25(OH) D levels were tested to be 13 ng/mL. She also has hypothyroid

but admits she is semi-noncompliant w/ her thyroid meds.

She has tried several dosages (250-5,000 IU) of OTC vitamin D3 with the

same effects beginning about 1 week after starting: hot flashes, vaginal

bleeding, sleeplessness, " feeling crazy " . Has anyone heard of these types

of side effects from vitamin D supplementation? Could trying

an ergocalciferol formula make a difference?

Any help or suggestions would be appreciated!

Sometimes it's not the vitamin but the excipients in the vitamin.  For example,

if the supplement contains soy and she has a soy allergy or sensitivity, it

might be the soy, not the vitamin D that is causing the problem.   I'd start

there first.   If she has a problem with the soy,  Bluebonnet sells a tablet

without the soy.   Also, magnesium is vitamin D's biggest cofactor...... I would

also add some magnesium (not oxide) to her supplementation regimen to make it

more effective.
