Vitamin D Supplements: 4 Warning Signs You May Be Taking Too Much
-
Nausea or vomiting — Excess vitamin D can raise calcium levels in the blood, causing digestive symptoms.
-
Extreme thirst and frequent urination — These can occur when vitamin D toxicity leads to high calcium levels.
-
Weakness or unusual fatigue — Elevated calcium may affect muscles and overall energy.
-
Confusion or kidney problems — Severe vitamin D toxicity can cause confusion, dehydration, kidney stones, or impaired kidney function.
Important: Vitamin D toxicity is usually caused by excessive supplementation rather than getting too much vitamin D from sunlight. If you’re taking high-dose vitamin D and develop these symptoms, contact a healthcare professional rather than taking additional doses.
