A vitamin D level of 7 ng/mL indicates severe deficiency and requires proper treatment. However, since you are taking Uprise D3 60K Oral Solution 5 ml and experiencing severe diarrhoea each time, this should not be ignored or self-managed by repeatedly stopping it. Uprise D3 usually does not cause severe diarrhoea, so this reaction may be due to individual intolerance to the formulation or excipients, or to an unrelated gut issue that becomes noticeable after taking it. You should consult a doctor to change the treatment plan rather than continue the same product, as they may switch you to a different vitamin D preparation, adjust the dosing schedule, or use a supervised regimen while also checking calcium levels and evaluating for any gastrointestinal causes. Stay hydrated and seek medical review so your deficiency can be treated safely without triggering recurrent symptoms.
