Who is at risk for low vitamin D?
In Singapore,
people have low vitamin D levels2
For most people, not getting enough sunlight is the main reason for low vitamin D. Other factors can also play a role, and certain groups of people are at higher risk.
 People with low sun exposure People who spend most of their time indoors, wear clothing that covers most of their skin or use sunscreen regularly may have limited ability to produce vitamin D from sunlight. Sunlight that passes through windows does not help, and sunscreen can block up to 99% of the UVB rays needed for vitamin D production. |
 People with darker skin tones The natural pigment in darker skin, called melanin, acts like a natural sunscreen. While this offers good protection from the sun, it also reduces the skin's ability to produce vitamin D.3 |
 Elderly adults As we age, our skin becomes less efficient at producing vitamin D from sunlight. Older adults also tend to spend more time indoors, further lowering their sun exposure.3 |
 Infants Babies who are exclusively breastfed are at risk because breast milk is not a good source of vitamin D.5 |
 People with obesity Extra body fat can "trap" vitamin D, making it less available for the body to use.3 Lifestyle habits (such as less outdoor activity) may also contribute. |
 People with certain health conditions Some health issues can prevent the body from absorbing vitamin D from food.6 This includes people who have had gastric bypass surgery or have conditions that affect the intestines.6 |
