Vitamin D in Menopause: Why It Becomes Especially Important Now
Why Menopause is a Turning Point for Bone Metabolism
With the onset of perimenopause, estrogen levels decline – and estrogen plays a key role in protecting bones. When this protection is lost, bones degrade faster than new bone tissue can be formed. The result: The risk of osteoporosis significantly increases during this phase of life. According to professional societies, around six to eight million people in Germany live with osteoporosis, with women being particularly affected after menopause.
Vitamin D cannot stop this process, but it can support it: It promotes the absorption of calcium and phosphate from the intestine, making it an important prerequisite for calcium to be incorporated into bones at all.
How much Vitamin D is recommended during menopause?
For women in menopause, the general recommendation of the German Nutrition Society (DGE) of 20 µg (800 IU) of Vitamin D per day initially applies, provided there is no sufficient endogenous production.
In cases of already diagnosed vitamin D deficiency and increased risk of falls or fractures, the Dachverband Osteologie (DVO) recommends a targeted intake of 800 to 1,000 IU of Vitamin D daily in combination with around 1,000 mg of calcium through diet for postmenopausal women. The German Menopause Society suggests a similar range of 1,000–2,000 IU of Vitamin D daily in tablet form for basic osteoporosis prevention therapy.
Why women over 40 are particularly affected
As early as around 40 years of age, the skin's ability to produce Vitamin D under sunlight changes – an effect that, according to current studies, particularly affects women. When the hormonal changes of menopause are added, two risk factors for bone health overlap at the same time.
The German Society for Endocrinology (DGE) therefore recommends that women actively address the issue of bone health, at the latest with the onset of menopause – for example, through a bone density measurement (DXA) if there is an increased risk – instead of only reacting after the first bone fracture.
Diet and Lifestyle as a Basis
- Calcium-rich foods: Dairy products, calcium-rich mineral water, green leafy vegetables
- Vitamin D sources: Fatty sea fish, egg yolk, fortified foods
- Moderate sun exposure: Regularly outdoors if possible, face and arms uncovered
- Strength and impact training: Actively stimulates bone formation; smoking and high alcohol consumption counteract this
- Medical clarification for increased risk: Especially with early menopause, family history, or existing menopausal symptoms
Frequently Asked Questions (FAQ)
Is the general adult dose of 20 µg also sufficient during menopause?
For most healthy women, yes. In cases of proven deficiency or increased fracture risk, a doctor may recommend a higher, individually adjusted dose.
Can Vitamin D relieve menopausal symptoms themselves (e.g., hot flashes)?
Vitamin D primarily affects bone and calcium metabolism. A direct effect on classic menopausal symptoms like hot flashes has not been scientifically proven in the same way.
Should I have my Vitamin D level tested?
In cases of increased osteoporosis risk (e.g., family history, early menopause, low sun exposure), a medical examination including a blood test may be advisable to individually adjust supplementation.
