Vitamin D is made by the body when sunlight hits our skin and is also found in some foods. However certain factors can hinder how much vitamin D we are able to make or absorb from our diet. Because of this certain groups of people are at great risk of a vitamin D deficiency. 

• Breastfed babies
• Babies fed formula with insufficient vitamin D levels
• People who spend little time outside, keep skin covered, or wear sunblock
• People who live at higher latitudes where the sun’s rays are weaker in the fall and winter (Canada)
• Children and adults using steroids long term
• Post-menopausal women
• Those living in long-term care homes or assisted living
• Overweight or obese individuals
• People with conditions that affect gut health such as Crohn’s and celiac disease
• Vegans and vegetarians
