Vitamin D levels

Expert groups disagree slightly on the cut-offs, and these are the ones many labs print.

Level (ng/mL)Meaning
Below 20Deficient
20 to 29Insufficient
30 to 100Sufficient
Above 100High

Why it is so common here

  • Staying indoors and covering the skin in the sun.
  • Darker skin makes less vitamin D from sunlight.
  • Few foods are naturally rich in it.

What can help

Sensible time in the sun, oily fish, eggs and fortified foods all help. Ask your doctor before taking high-strength supplements, because too much can harm your kidneys.

Common questions

Still unsure? Send us the question and a person — not a bot — will answer it.

What is a normal vitamin D level?

Many labs treat 30 to 100 ng/mL as sufficient. If your report is in nmol/L, divide by 2.5.

What are the symptoms of low vitamin D?

Often none. It can cause tiredness, bone pain and muscle weakness.

Can too much vitamin D be harmful?

Yes. Very high levels raise calcium and can damage the kidneys, usually from too many supplements.
