Vitamin D Not Responding to Supplementation- Seeking Insights

chaiyosef,
chrones or celiac can prevent the absorption of D. Are you taking D2 or D3? There is an intramusular injection that would avoid malabsorption issues in the small intestine.
Your kidneys convert D to useable D. Low kidney function can cause hyperparathyroidism.
But fluctuating levels of PTH can be indicative of primary hyperparathyroidism. I'd want my parathyroids checked before any starting treatment for osteoporosis.

Thanks for your input! I’ve been working with specialists, and my nephrologist does not suspect kidney issues. My parathyroid function has been evaluated, and while my PTH has fluctuated, my specialist does not think it’s a primary issue. I’m taking D3, and I’ve been increasing my dose significantly over the past year, but my levels still aren’t rising. Celiac hasn’t been ruled out completely, but my nephrologist doesn’t think it’s likely. That’s why I’m wondering if there are other absorption-related factors I should be considering.
