What does it mean if your Vitamin D3 result is too low?
Deficiency Symptoms: Osteoporosis results from an imbalance between bone resorption and bone formation. Decreased vitamin D levels result in decreased production of the active vitamin form, vitamin D3. Vitamin D enhances the efficiency of calcium absorption. Chronic vitamin D deficiency results in decreased calcium absorption and secondary hyperparathyroidism.
Vitamin D3 has been found to have anticarcinogenic activity, inducing apoptosis in many types of cancer cells. It has also been useful in the treatment of psoriasis when applied topically.
Vitamin D appears to demonstrate both immune-enhancing and immunosuppressive effects.
Repletion Information: Supplemental vitamin D is available as vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol). The Food and Nutrition Board of the Institute of Medicine of the National Academy of Science recognizes the biological activity of vitamins D2 and D3 are equivalent with age related intakes.
For both men and women recommended doses:
- Age 19-50 years 200 IU/day (5.0 micrograms)
- Age 51-70 years 400 IU/day (10 micrograms)
- Greater than 70 years 600 IU/day (15 micrograms)
Dosages over 3000 IU/day are associated with hypercalcemia, causing multiple debilitating effects. Anorexia, nausea and vomiting have been observed at doses as low as 1250 IU/day. The prolonged ingestion of excessive vitamin D and the accompanying hypercalcemia can result in metastatic calcification of soft tissues, including kidney, blood vessels, heart and lungs.
