High vitamin D results but have symptoms of low D. Is this possible?

[Everdean]

I have osteoporosis, and spinal stenosis, waiting for surgery.My latest blood test for vit. D is -

Serum total 25-hydroxy vitamin D levels. 174nmol/L. [. >51]at risk of toxicity, consider discontinuation of suppliments.

I have discontinued but I remember reading somewhere that as I have coeliacs disease, I may have a problem with absorbing the vitamin.

Hence loads swimming about in the blood, but maybe not being absorbed successfully. This is the case of T4 conversion. Also B12. .

Has anyone heard of this please?

Thank you.

I would think that if you had such a high vitamin D, that's your calcium lab would also be elevated. If you have been adhering to a strict gluten-free diet, your intestinal lining may heal, improving nutrient absorption. This could result in higher levels of vitamin D if you continue taking the same supplement dose that was intended to compensate for malabsorption.

Too much vitamin D can have an adverse impact on bone mineral density, I'm afraid. One study found a difference for those taking 4,000 IU or 10,000 IU daily for three years, compared with those taking 400 IU daily.

Coeliac disease can cause problems absorbing micronutrients. Your high level of serum vitamin D shows that what you are supplementing is getting into your bloodstream. Vitamin D, magnesium and calcium are said to work together, to ensure calcium is utilised, and K2 (often added to vitamin D supplements) helps the calcium deposit in one's bones, rather than soft tissues.

Have you had a recent Bone Profile blood test? It would show your serum calcium level, which is vital for nerve signalling and allows muscles to relax, rather than spasm. But you don't want it too high (hypercalcaemia), which may be a risk of having high vitamin D.
