To conclude, our findings suggest an association between large-dose vitamin D supplementation in infancy and an increased risk of atopy, allergic rhinitis, and asthma later in life. Further study is required to determine whether these observations could imply that vitamin D supplementation in infancy may have long-term effects on immune regulation, or if they reflect some unmeasured determinants of vitamin D supplementation

CONCLUSIONS: A 2-week course of HT significantly improved vitamin D balance by increasing serum calcidiol concentration, and caused a marked healing of AD. These parallel positive responses should be taken into account when the benefits of HT are considered..

A study led by researchers at the University of California, San Diego School of Medicine suggests that use of oral Vitamin D supplements bolsters production of a protective chemical normally found in the skin, and may help prevent skin infections that are a common result of atopic dermatitis, the most common form of eczema.
