Vitamin D plays an important role in bone health, muscle function and immune health. While our bodies can produce vitamin D from sunlight, many people don't get enough year-round.

The risk of low vitamin D is higher for people who spend a lot of time indoors, cover up for cultural, practical or medical reasons, regularly use sun protection, have darker skin, or get limited sun exposure. Where you live in New Zealand also makes a difference. The further south you live, the less UVB radiation is available during the winter months, making it harder to produce adequate vitamin D from sunlight alone. This is particularly relevant for those living in the lower South Island.

Food sources of vitamin D are relatively limited, which is why supplementation can be a useful option for some people, particularly during autumn and winter when sunlight exposure tends to be lower.

If you are concerned about your vitamin D status, a blood test can help determine whether your levels are adequate and whether supplementation may be beneficial. This is especially worth considering if you have risk factors for deficiency or have been advised by your healthcare provider to monitor your vitamin D levels.

Please note: Supplements are not a replacement for a balanced diet or personalised health advice. If you are pregnant, breastfeeding, taking medication, have a medical condition, or are unsure whether vitamin D is right for you, please check with your healthcare provider or one of my Dietitians or Nutritionists at Mission Nutrition. It can also be helpful to have your vitamin D levels tested, especially if you are considering long-term supplementation.
