Vitamin D3Improves Steroid Therapy

MARCH 01, 2006

Researchers have found that taking vitamin D3 supplements may enhance the response to steroid treatments among patients with asthma who normally do not have a positive response from steroid therapy. Whereas inhaled steroids work for a majority of patients with asthma, other patients benefit only from steroid tablets.

The study results, published on-line in the Journal of Clinical Investigation (December 8, 2005), showed that vitamin D3improves the responsiveness of immune system T cells to steroids. The supplement does so by inducing T cells to generate interleukin-10, a molecule that slows down the immune response that causes asthma and allergy symptoms. The researchers noted that the benefits of vitamin D3 supplements in asthma patients need further investigation.
