Survey spotlights rise of vitamin D in 2021

Vitamin D usage in the U.S. rose 10 percentage points over the past year, according to 2021 CRN survey data. Vitamin D has gained attention during the COVID-19 pandemic for its role in supporting immune health—and, more specifically, helping to combat respiratory infection. 

The CRN Foundation's "Vitamin D & Me!" website provides a compilation of research, news, and opinions from medical and research experts on the role of vitamin D and COVID-19.

All eyes on immune health: Vitamin D is among the list of ingredients that have seen a significant increase in usage over the last 12 months as research and news reports point to them as potentially helpful in boosting overall immunity:

  • Vitamin D (52% vs. 42% in 2020)
  • Vitamin C (40% vs. 35%)
  • Zinc (22% vs. 15%)

More than supplements: 45% of all respondents indicated they’ve had their vitamin D levels checked by a healthcare provider at some point during the pandemic.
