Are you taking vitamin D supplements without your doctor’s advice? Although these medications are widely sold over the counter, self-treatment can be dangerous. Many people today rely on vitamin supplements to stay healthy, often without understanding proper use or dosage. This can lead to serious health complications, especially when it comes to vitamin D.The COVID-19 pandemic, which has kept millions indoors, has led to widespread vitamin D deficiency due to limited sunlight exposure. Taking vitamin D supplements has become a popular trend since the pandemic. However, indiscriminate use of these supplements without medical supervision may cause more harm than good. Both deficiency and excess of vitamin D can have negative health effects.
How Vitamin D Supports Bone Health, Muscle Function, and a Strong Immune System
Vitamin D plays an important role in maintaining strong bones, supporting muscle performance and strengthening immune defenses. This helps the body absorb calcium, phosphorus and minerals essential for bone strength and density. Adequate vitamin D levels also aid muscle coordination and improve the immune system’s ability to fight infection and inflammation.
Health Risks of Excessive Vitamin D
Vitamin D deficiency has well-known consequences, but consuming too much can be just as harmful. Excess vitamin D increases calcium levels in the body, a condition known as hypercalcemia. The normal calcium level is 8.5 to 10.2 mg/dL, and if it exceeds this level, symptoms such as abdominal pain, vomiting, fatigue, and weakness may appear.Paradoxically, consuming too much vitamin D can also weaken your bones. Hypercalcemia can cause bone pain, muscle tension, and even bone loss. Excess calcium can put additional strain on the kidneys, potentially leading to nephrocalcinosis, a condition in which calcium is deposited in kidney tissue. Over time, this can impair kidney function and lead to kidney failure.Excessive vitamin D can also reduce your appetite, causing nausea or an aversion to food. These symptoms often occur when supplements are taken inappropriately.Several clinical studies have shown that vitamin D is essential for strong bones and immunity, but excessive intake can be harmful. Studies published in journals such as Frontiers in Endocrinology have shown that oversupplementation can lead to high calcium levels, known as hypercalcemia, which can lead to nausea, fatigue, and even bone pain. Long-term excessive consumption can put strain on 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 Use Vitamin D Supplements Safely
You should not take vitamin D supplements without consulting your doctor. Your healthcare professional can use a blood test to evaluate your vitamin levels and prescribe the correct dosage for your needs. Self-prescribing or taking high doses from over-the-counter medications may pose serious health risks rather than provide benefits.Maintaining the right balance of vitamin D is essential for bone strength, muscle function, and overall health. Always prioritize natural sources such as sunlight and a balanced diet, and seek medical advice before using supplements.Also Read | HEART HEALTH WARNING: Stem cell therapy may reduce the risk of heart failure even after a heart attack.
