Having naturally very dark skin. This includes people from Africa, the Indian subcontinent and Middle East.
Your skin not being regularly exposed to sunlight, eg:
avoiding the sun because you have a high risk of skin cancer or are on photosensitising medications (these are medicines that make your skin more sensitive to the sun – your pharmacist or doctor will have advised you)
regularly wearing clothing that covers a lot of your skin (eg, veils or other clothing covering your legs, arms and face), or
not going outside.
If you live in the South Island (especially south of Nelson-Marlborough) and get little time outdoors in the middle of the day between May and August, you may be at risk of vitamin D deficiency in spring. You may wish to consider taking vitamin D tablets from May to August.
If you have liver or kidney disease, or are on certain medications that affect vitamin D levels, you may be at risk of vitamin D deficiency.
However.......see a GP. Overdose can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.
