9 Side Effects of High Doses of Vitamin D

Vitamin D is a very important nutrient for efficient functioning of muscles, heart, lungs and brain. This vitamin helps your body absorb minerals, such as calcium and phosphorus, which are essential for building bones. Consuming vitamin D through foods or supplements benefits your health in many ways. Such as reducing weight, supporting bone health, reducing depression, preventing heart disease, etc. But, excessive intake of vitamin D can also be harmful for your body. Today in this article, we are telling you about the side effects of overdose of vitamin D.

Kidney may cause damage

Having high amounts of vitamin D can cause kidney damage, that is, your kidney may be impaired. This is because high amounts of vitamin D increase calcium levels in the blood, causing kidney damage. One study has shown that vitamin D poisoning can cause severe kidney injury. Its symptoms look like fever, nausea, vomiting and severe abdominal pain.

Hypercalcemia

Vitamin D poisoning leads to hypercalcemia. Actually, this is a condition when the calcium levels in your blood are above normal. High levels of vitamin D leads to calcium uptake that your body absorbs and can cause many complications, such as loss of appetite, confusion, and high blood pressure. The symptoms are chest pain, high blood pressure, irritability and anxiety.

Weak Bones

Vitamin D in high amounts causes bone loss and brittle bones. This is because high levels of vitamin D lead to low levels of vitamin K2 in the blood. The primary function of vitamin K2 is to conserve calcium in bones and vitamin K2 activity can be reduced by excess of vitamin D. When your bones begin to weaken, you may experience symptoms such as bone pain, severe back or joint pain, fracture and instability.

Irregular Heartbeat

Excessive intake of vitamin D causes hypercalcemia and this, in turn, can alter the proper functioning of heart cells, leading to irregular heartbeat. High calcium levels cause calcium deposition in the heart arteries, which can increase the risk of heart attack. Its symptoms look like chest pain, tiredness and dizziness.

Lung Damage High levels of Vitamin D increase the levels of calcium and phosphate in the blood which together form crystals. These crystals are more likely to accumulate in the lungs, which can disrupt its function, which can cause lung damage.
