⚠️ Vitamin D Warning: When You Should Recheck or Stop High-Dose Use
Vitamin D is essential for bone health, immunity, and calcium balance. However, excessive intake over time can lead to vitamin D toxicity, usually through elevated calcium levels in the blood.
This condition is called Hypercalcemia.

2. Excessive Thirst and Frequent Urination
High calcium affects kidney function.
