A key negative side effect of excessive vitamin D3 intake is hypercalcemia, a buildup of calcium in the blood, which can lead to several adverse health consequences.
Understanding Vitamin D3 Toxicity
Vitamin D3 is crucial for calcium absorption and bone health. However, taking too much vitamin D3 can lead to toxicity, primarily causing hypercalcemia.
Symptoms of Vitamin D3 Toxicity
According to the provided reference, the main negative side effects due to vitamin D3 toxicity are:
- Nausea and Vomiting: Elevated calcium levels can disrupt the digestive system.
- Weakness: Hypercalcemia can affect muscle function, leading to generalized weakness.
- Frequent Urination: The kidneys try to filter out excess calcium, leading to increased urine production.
Potential Long-Term Complications
If vitamin D3 toxicity is prolonged, it can lead to more severe problems such as:
- Bone Pain: Paradoxically, excessive vitamin D can weaken bones in the long run.
- Kidney Problems: High calcium levels can cause kidney damage and the formation of calcium stones.
