The sunshine vitamin

What is vitamin D3?

Vitamin D3 — known as cholecalciferol — is the form of vitamin D your body makes when sunlight reaches your skin. It helps the body absorb calcium and plays a part in normal bone, muscle and immune function. It's a normal part of how the body works.

Made by sunlight

Sunlight on the skin is the body's main natural source of vitamin D — which is why it earned the nickname “the sunshine vitamin.” Time in the sun lets the body produce it.

Hard to get from food

Few everyday foods contain much vitamin D, so diet alone usually provides only a small amount. For most people, sunlight does the heavy lifting.

Vitamin D in Kenya

Plenty of sun — yet low levels are common

Kenya has no shortage of sunshine, but modern life keeps many of us out of it: long indoor hours at a desk, in a car, away from the midday sun. Levels can quietly drift low.

17.4%
of healthy Nairobi adults were vitamin D deficient in a hospital study.
Aga Khan University Hospital, Nairobi — BMC Endocrine Disorders (2018).
~43%
of the same group were insufficient — only about 4 in 10 had sufficient levels.
BMC Endocrine Disorders (2018), Nairobi adults.
Urban life
Indoor lifestyles and limited sun exposure are linked to rising vitamin D deficiency.
Kenyan health reporting (2025); Lancet Global Health Africa review (2019).
Who tends to run low
· People who work mostly indoors · Older adults · Little direct sun exposure · Mostly covered skin · During pregnancy (ask your doctor)

These are general risk situations, not a diagnosis. Only a blood test and a clinician can confirm your vitamin D status.

Good to know

Vitamin D3, answered

General health awareness about the sunshine vitamin. This is not medical advice or a substitute for a qualified healthcare professional.

What is vitamin D3 (cholecalciferol)?
Vitamin D3, or cholecalciferol, is the form of vitamin D your body makes when sunlight reaches your skin. It helps the body absorb calcium and plays a part in normal bone, muscle and immune function.
Why is it called the sunshine vitamin?
Because sunlight on the skin is the body's main natural source of vitamin D. Time outdoors in the sun lets the body produce it — hence the nickname.
Can I get enough vitamin D from food alone?
Few everyday foods contain much vitamin D, so diet alone usually provides only a small amount. Sunlight is the main source for most people, which is why limited sun exposure can leave levels low.
How do I know if my vitamin D is low?
A simple blood test called 25-hydroxyvitamin D measures your level. Talk to your doctor about whether testing is right for you — only a test and a clinician can confirm your status.
Who is most likely to have low vitamin D in Kenya?
People who spend most of the day indoors, older adults, and those with little direct sun exposure are more likely to have lower vitamin D. A study of healthy Nairobi adults found about 1 in 6 were deficient, and many more insufficient.
