1 Sudden increase in blood calcium
Most side effects of vitamin D in large amounts cause poisoning and can also increase the release of calcium from the bones into the bloodstream.
2. Nausea, vomiting, and poor appetite
Excessive side effects of vitamin D include nausea, vomiting, and poor appetite.
3 Abdominal pain or digestive problems:
Increased calcium levels due to vitamin D poisoning causes abdominal pain, constipation, and diarrhea.
4. The kidneys are damaged by the kidneys.
The kidneys are very vulnerable to calcium deposits, which can cause permanent kidney damage and eventually kidney failure.
5 Irregular heartbeat
Extremely high levels of calcium in the blood, in addition to causing irregular heartbeats, may cause calcium deposits or plaque in the arteries or valves of the heart.
6 Decreased bone density
Very high doses of this vitamin may lead to a deficiency of vitamin K2 in the blood and cause calcium to be excreted from the bone tissue.
7. Dehydration
Increased levels of vitamin D increase the activity of the kidneys, which increases the frequency of urination and causes dehydration.
