That headline is too alarmist. Vitamin D is important, and most people taking an appropriate dose do not need to stop it because of ordinary symptoms. Problems usually arise from excessive vitamin D supplementation, which can cause dangerously high blood calcium levels.
Symptoms that can occur with too much vitamin D
Watch for:
-
Nausea, vomiting, or loss of appetite
-
Excessive thirst and frequent urination
-
Weakness, fatigue, confusion, or unusual drowsiness
-
Kidney-related symptoms, such as kidney stones or significant flank pain
These can result from hypercalcemia (high blood calcium) caused by excessive vitamin D, rather than from a normal recommended dose.
If you develop these symptoms while taking high-dose vitamin D, contact a healthcare professional promptly. Severe confusion, repeated vomiting, severe weakness, or other serious symptoms warrant urgent medical attention.
Also, don’t stop a prescribed vitamin D treatment solely because of a social-media headline. If you’re taking a high-dose regimen, your clinician may need to check your vitamin D and calcium levels and adjust the dose.
If you tell me how many IU (or micrograms) of vitamin D you’re taking per day and why you’re taking it, I can explain whether that dose is generally considered low, typical, or high.
