Can a vitamin d boost shield transplant patients from major health threats?

This study aimed to see if a high dose of vitamin D could better protect kidney transplant patients from serious health problems like new diabetes, heart disease, cancer, and death, compared to a standard lower dose. It involved over 500 patients who were 1-4 years past their transplant and had low vitamin D levels. Participants were randomly assigned to receive either a high or low dose of vitamin D for two years, and researchers tracked their health outcomes.
