As we’re spending more time in our homes, a daily dose of Vitamin D has never been more important to help you and your family stay well. But, is it possible to have too much Vitamin D?
We all need enough Vitamin D, but it is possible to have too much of a good thing. It’s almost impossible to get too much Vitamin D from your diet or from sunlight. Food sources can only deliver a limited amount of the vitamin, and your body is great at regulating its own Vitamin D. Any extra produced by exposure to sunshine is stored in your body fat.
Many people turn to taking Vitamin D supplements, especially in the winter months when they feel they are not getting enough exposure to sunlight. This is great but it is possible to have too much Vitamin D so you should be responsible with your approach to supplementation.
The most extreme levels of overdosing on Vitamin D in supplement form is called hypervitaminosis D. Toxicity is rare, but could be serious. It’s easy to avoid: be aware of your supplement’s dose, and only take the recommended daily amount.
Latest Government guidelines from Public Health England suggest 10 micrograms (400 iu) of Vitamin D for adults and children aged 12+ months. If you stay within these guidelines, you are unlikely to experience any ill-effects. The only caveat to this would be if your body lacks the ability to absorb or utilise Vitamin D.
What are the risks?
If you were to take too much Vitamin D from a supplement (or from large doses of cod liver oil), you are at risk of high levels of calcium in your blood. The medical term for this is hypercalcemia. It could result in nausea and constipation. It could also affect your mental capacity, leaving you feeling fuzzy-headed and confused. In extreme cases, it could lead to kidney stones.
