If you need to spend time in the hospital for a planned operation, it may make sense to boost your vitamin D levels first. Recent research indicates that people with good levels of circulating vitamin D, at least 30 ng/ml, are significantly less likely to catch an infection while they are hospitalized. Health care acquired infections can lead to pneumonia, diarrhea or sepsis, and cause an estimated 100,000 deaths each year. Treating them is costly in time, money and suffering.
