Trouble absorbing vit d3

[Dryski]

I'm on vit d3 50,000 weekly and have been for many years. Last level only shows 40. How is this possible. I'm usually about double that. This is prescription strength.

Are you based in the U.K.?

What unit is vitamin D test results nmol or ng/ml

Are you also supplementing magnesium?

You could vitamin D mouth spray daily

[Dryski in reply to SlowDragon]

United States. Test was 40 ng ml. 30 to 100 is sufficient but I just don't absorb things well.

[SlowDragon Administrator in reply to Dryski]

So 40ng/ml = 100nmol in U.K. units

So its good level

Suggest you try smaller dose vitamin D daily

And often mouth spray works better as avoids poor gut absorption

Web links about taking important cofactors - magnesium and Vit K2-MK7

Magnesium best taken in the afternoon or evening, but must be four hours away from levothyroxine

No magnesium just 50,000 jell cap. Decided to stop for awhile because my calcium is high and feeling quite sick with stomach issues.

Can you also give the last few D test values you’ve had?
