Vitamin D may help lung tissue to rejuvenate, a process that occurs throughout life but declines with age. The most important source of vitamin D is sun exposure, which leads to synthesis of vitamin D in the skin. Good food sources of vitamin D include fortified milk and seafood, such as herring, salmon and mackeral. To ensure that you’re getting enough vitamin D, take a supplement daily. To aid lung function, most people need about 20 micrograms (mcg) of vitamin D a day…people over age 50 need double that amount — about 40 mcg.
