Are you taking Vitamin D supplements without a doctor’s advice? While these pills are widely available over the counter, self-medicating can be risky. Many people today rely on vitamin supplements to maintain their health, often without understanding proper usage or dosage. This can lead to serious health complications, especially when it comes to Vitamin D.The COVID-19 pandemic, which kept millions indoors, resulted in widespread Vitamin D deficiency due to limited sun exposure. Following the pandemic, taking Vitamin D supplements became a popular trend. However, indiscriminate use of these supplements without medical supervision can do more harm than good. Both deficiency and excess of Vitamin D can negatively impact your health.

Health hazards of excessive Vitamin D

While Vitamin D deficiency has well-known consequences, consuming too much can be equally harmful. Excess Vitamin D increases calcium levels in the body, a condition known as hypercalcemia. Normal calcium levels range from 8.5 to 10.2 mg/dL, and surpassing this can lead to symptoms such as stomach pain, vomiting, fatigue, and weakness.Paradoxically, too much Vitamin D can also weaken bones. Hypercalcemia may cause bone pain, muscle tension, and even bone loss.

The excess calcium puts extra strain on the kidneys, potentially leading to calcium deposits in kidney tissue, a condition called nephrocalcinosis. Over time, this impairs kidney function and may result in kidney failure.Excessive Vitamin D can also reduce appetite, causing nausea or aversion to food. These symptoms often arise when supplements are taken inappropriately.As per several clinical studies, while Vitamin D is essential for strong bones and immunity, excessive intake can be harmful. Research in journals such as Frontiers in Endocrinology show that over-supplementation can lead to high calcium levels, known as hypercalcaemia, causing nausea, fatigue, and even bone pain. Prolonged excess may also strain the kidneys, leading to calcium deposits and potential kidney damage. Experts warn that Vitamin D supplements should always be taken under medical supervision to avoid these serious health risks.

How to safely use Vitamin D supplements

Vitamin D supplements should never be taken without consulting a doctor. A healthcare professional can assess your vitamin levels through a blood test and prescribe the correct dosage tailored to your needs. Self-prescribing or taking high doses from over-the-counter sources can create serious health risks rather than providing benefits.Maintaining the right balance of Vitamin D is essential for bone strength, muscle function, and overall well-being. Always prioritise natural sources like sunlight and a balanced diet, and seek medical guidance before turning to supplements.Also Read | Heart health alert: Stem cell therapy promises to reduce heart failure risk even after a heart attack
