Breathe Better by Taking Vitamin D Study Suggests

Asthma and COPD sufferers seem to be able to stop or to slow the decline of the "human airway muscle" that restricts breathing - simply by taking Vitamin D according to a new study from the University of Pennsylvania.

That's great news (thank you We Are Breathless for telling us). For once a low-cost, easy-to-follow option.

Calcitriol, a form of vitamin D synthesized within the body, that can also be administered, can "prevent or forestall the irreversible decline in breathing that leaves many asthmatics even more vulnerable when they suffer an asthma attack."
