Are There Any Side Effects Of Vitamin D
Vitamin D is an essential nutrient that plays a vital role in the body's overall health. It is responsible for promoting bone health, regulating the immune system, and aiding in the absorption of calcium and phosphorus. However, like most things, too much of a good thing can have negative consequences. In this article, we will discuss the potential side effects of vitamin D.
How Much Vitamin D Is Too Much?
The recommended daily intake (RDI) of vitamin D for adults is 600-800 IU (international units) per day. However, many people take vitamin D supplements or consume foods that are high in vitamin D to ensure they are getting enough of this essential nutrient.
The National Institutes of Health (NIH) state that the safe upper limit for vitamin D intake is 4,000 IU per day for adults. However, some studies suggest that consuming more than 10,000 IU per day can lead to toxicity and cause adverse side effects.
What Are The Side Effects Of Too Much Vitamin D?
Consuming too much vitamin D can cause a condition called vitamin D toxicity. Symptoms of vitamin D toxicity include:
- Nausea and vomiting
- Weakness
- Stomach pain
- Constipation
- Confusion and disorientation
- Increased thirst and urination
Severe cases of vitamin D toxicity can lead to kidney damage, as well as bone loss and fractures. It is important to speak with a healthcare provider before taking high doses of vitamin D supplements.
Who Is At Risk For Vitamin D Toxicity?
Vitamin D toxicity is rare but can occur in individuals who consume high doses of vitamin D supplements or have underlying medical conditions that cause them to absorb too much vitamin D.
Individuals who are at risk for vitamin D toxicity include:
- Those who take high doses of vitamin D supplements without medical supervision
- People with medical conditions that cause them to absorb too much vitamin D, such as sarcoidosis or lymphoma
- Those who have high calcium levels in their blood
Can Vitamin D Supplements Interact With Other Medications?
Vitamin D supplements can interact with certain medications, including:
- Calcium channel blockers

It is important to speak with a healthcare provider before taking vitamin D supplements if you are currently taking any medications.
