BMJ Case Reports CP 2022;15:e250553.
Learning points
Patients are encouraged to seek the opinion of their general practitioners regarding any alternative therapy or over-the-counter medications they may be taking or desire to initiate.
Nutritional causes of hypercalcaemia should always be excluded early in patients before investigating alternate pathological causes.
This case report further highlights the potential toxicity of supplements that are largely considered safe until taken in unsafe amounts or in unsafe combinations.
