Vitamin D and Asthma...Deficiency linked to asthma

Recent reviews of the medical literature indicate that vitamin D deficiency is linked to asthma. A 2010 study in the Allergy, Asthma & Immunology that vitamin D deficiency may be linked to airway inflammation, decreased lung function and poor asthma control. It appears that vitamin D helps improve asthma symptoms by preventing the release of inflammatory cytokines and increasing the secretion of anti-inflammatory proteins. Vitamin D is found in foods, such as eggs and fish. It is also produced in the body after sun exposure. Most Americans are deficient in vitamin D, especially at the end of the winter. Supplementing daily with Beyond Health’s Vitamin D3 Formula is recommended.
