Strictly speaking vitamin D is not a vitamin but a hormone the skin produces under sunlight. It controls calcium absorption from the gut and is therefore central to bone and muscle health.
In women's health it matters mainly around bone health: during menopause, on anti-hormonal therapy after breast cancer, in osteoporosis, and in pregnancy and breastfeeding.
In Switzerland low vitamin D levels are very common during the winter half of the year. The more useful question is usually not 'what is my level?' but 'am I taking enough?'.
Key facts
At a glance.
- Basic insurance reimburses the 25-OH vitamin D blood test only for defined indications – not as a routine or on-request check.
- Without an indication the test costs roughly CHF 40–70 out of pocket.
- Supplementation is inexpensive and in most cases reasonable without prior testing.
- Usual maintenance dose for adults: 800–1000 IU per day, for many sensibly year-round.
- Very high doses add no proven benefit and can cause harm – more is not better.
- In osteoporosis, vitamin D alone does not replace specific therapy.
Causes
Background and risk factors.
At the latitude of Basel the sun is too low from October to March for the skin to make meaningful amounts of vitamin D. Add indoor work, sun protection, darker skin types, covering clothing and reduced skin synthesis with age.
Risk factors
- Little time outdoors, shift work, mostly indoor activity
- Darker skin type or clothing that leaves little skin exposed
- Older age, residential care
- Obesity (vitamin D is stored in fat tissue)
- After gastric bypass or other bariatric surgery, malabsorption (e.g. coeliac disease, Crohn's disease)
- Medications such as antiepileptics, glucocorticoids, certain HIV drugs
- Pregnancy and breastfeeding
Symptoms & findings
How does it present?
Typical symptoms
- Often no symptoms at all – a low level is frequently an incidental finding
- Muscle weakness, muscle pain, unsteady gait
- Bone pain; in severe deficiency, osteomalacia
When testing is genuinely worthwhile
Testing makes sense when it changes something
osteoporosis or fracture, malabsorption, before certain bone therapies, kidney insufficiency, or persistent muscle and bone pain without another explanation. In healthy women without risk factors the number usually does not change the plan – supplementation is advised anyway.
Diagnostics
How the diagnosis is made.
The test measures 25-OH vitamin D in blood. The active metabolite (1,25-OH) is not suitable for assessing deficiency and is reserved for special situations.
Examinations
- Serum 25-OH vitamin D
- Depending on the situation: calcium, phosphate, alkaline phosphatase, parathyroid hormone, creatinine
- If osteoporosis is in question: bone density measurement (DXA)
What do the findings mean?
Common thresholds
below 25–30 nmol/l marked deficiency, 30–50 nmol/l insufficient, from about 50 nmol/l sufficient for bone health. Levels above 125 nmol/l show no proven added benefit.
Treatment
Possible approach.
Watchful waiting
A note on costs
in Switzerland, mandatory basic insurance covers the 25-OH vitamin D test only for defined indications – among them osteoporosis or fracture, malabsorption, chronic kidney insufficiency, certain medications, and monitoring of ongoing high-dose therapy. A test without such an indication is a self-pay service (roughly CHF 40–70). We tell you beforehand whether the test is covered in your situation – and whether it is needed at all.
Medication
Adults
- Usually 800–1000 IU vitamin D3 daily
- Higher and time-limited with risk factors or proven deficiency. Drops and tablets are equivalent
- What matters is taking it regularly, ideally with a meal containing fat. Supplementation is standard in pregnancy and breastfeeding. After gastric bypass or with malabsorption, substantially higher doses with follow-up testing are usually needed. Very high single 'loading' doses are used sparingly
Surgery
In osteoporosis or on aromatase inhibitors, vitamin D is part of the basics – together with calcium, strength training and, where indicated, specific osteoprotective therapy. Vitamin D alone does not replace it.
Prevention
What you can do yourself.
- Short, regular time outdoors without risking sunburn
- Supplement consistently through the winter half-year rather than hoping
- Oily fish, eggs and fortified products as a supplement – diet alone is rarely enough
- Strength training for muscle and bone, regardless of vitamin D level
