Important Warning: 4 Symptoms That May Mean You’re Taking Too Much Vitamin D
Vitamin D is essential for bone health, muscles, and immune function, but taking excessive amounts—especially high-dose supplements without medical supervision—can lead to vitamin D toxicity. This can cause high calcium levels in the blood, which may affect the kidneys and other organs.
If you take vitamin D supplements and develop these symptoms, contact a healthcare professional for advice:
1. Nausea, vomiting, or loss of appetite
Too much vitamin D can raise calcium levels, which may upset the digestive system and reduce appetite.
2. Excessive thirst and frequent urination
High calcium levels can affect the kidneys, causing increased thirst and more frequent trips to the bathroom.
3. Unusual weakness, fatigue, or confusion
Changes in calcium levels can affect muscles and the nervous system, leading to tiredness or difficulty concentrating.
4. Kidney-related symptoms
Pain in the side or back, kidney stones, or changes in urination may be warning signs that need medical attention.
What to do
- Do not take more than the recommended dose of vitamin D unless advised by a healthcare professional.
- If you are taking a high-dose prescription vitamin D treatment, speak with your prescriber before making changes.
- A blood test can help determine whether your vitamin D level is in a healthy range.
For most people, vitamin D is safe when taken appropriately. The concern is usually excessive intake over time, not normal recommended supplementation.
