A member asked:
When deficient in d does taking vitamin d3 cause calcium blood levels to rise or lower? i have read conflicting articles on this.

Usually no effect: One must be extremely deficient in vitamin d3 and parathyroid hormone, or calcium itself, to have serum calcium actually go low as a result. Intoxicating yourself with vitamin d3, which probably u won't do, will give you some hypercalcemia if the controls don't kick in well. We have a saying in the lab, "look at the person, not the numbers." glad ur d3 deficiency was found & rx'd; it's too common.

Vit D and calcium: Vitamin d enhances absorption of calcium from intestine. Calcium then goes to bone where it belongs. Blood calcium level will be regulated by your parathyroid gland and other metabolic factors. Supplementing vitamin d to keep your level of 25-hydroxy vitamin d between 50 and 70 has been shown to possibly prevent disease: cancer, diabetes, depression and dementia. Data r mixed. More studies needed.
