Vitamin D to the Rescue

According to a 2019 review, benefits of vitamin D are thought to include enhanced protection against heart disease, cancer, diabetes and depression, along with infections and viruses.

Unfortunately, so many people — 40 percent to 80 percent of Americans, depending on factors such as race, for example— are lacking in vitamin D. This is why most adults, children, and even infants and breastfed babies are now encouraged to supplement with vitamin D.
