Taking Vitamin D supplements? Know the benefits, health hazards and risks

The CSR Journal Magazine

Are you popping Vitamin D pills? Are you doing it without doctor’s prescription? Then beware, you are inviting trouble for yourself! Many people self-medicate. They buy handfuls of vitamin supplements to keep their bodies healthy. Various supplements can be obtained from drugstores without a doctor’s prescription. Many people take supplements these day after day without following and even knowing the correct rules.

The Covid-19 pandemic which struck the world five years ago and left almost everyone Vitamin D deficient due to lack of exposure to the sun. After the pandemic, the habit of taking Vitamin D supplements has become a fad.

There are many people who take vitamin D supplements as they wish without medical advice. This habit is very harmful for health. Just as problems arise due to lack of vitamins in the body, physical problems can also arise if you take too much vitamin!

Why does our body need Vitamin D?

Human body needs Vitamin D to absorb calcium and phosphorus, which are crucial for building and maintaining strong bones. Beyond bone health, Vitamin D is also essential for muscle function, nerve signaling, and a properly functioning immune system.

Vitamin D is not only very beneficial for strong bones, but also for the overall well-being of the body. If you wake up every day and stay under the sunlight for a while, then you will not have a deficiency of vitamin D. However, if there is a deficiency of this vitamin in the body, then vitamin D supplements are the best option.

What are the natural sources of Vitamin D?

Instead of popping pills, try to get Vitamin D in your body naturally. Our bodies produce Vitamin D naturally when the skin is exposed to sunlight. However, the amount produced can vary due to location, season, and skin tone.

Other sources of Vitamin D include foods like fatty fish (trout, salmon, tuna), egg yolks, and cheese contain small amounts. Many common products, such as milk, cereals, and yogurt, are fortified with Vitamin D. Natural sources of vitamin D include fatty fish (like salmon, tuna, and sardines), fish liver oils, egg yolks, beef liver, and certain mushrooms. Some of these foods, particularly fatty fish, are among the best natural sources, while others like egg yolks and beef liver contain smaller amounts.

What are the health hazards of consuming excessive Vitamin D?

Just as vitamin D deficiency causes some problems in the body, excess vitamin D is dangerous for the body. If more vitamin D is in the body than required, several physical problems arise.

Excessive vitamin D in the body also increases the amount of calcium. The normal level of calcium in our body is 8.5-10.2 mg/dL. If it is excessive, it is called ‘hypercalcemia’. In this case, symptoms such as stomach pain, vomiting, excessive fatigue, weakness occur when the normal level is exceeded.

Vitamin D is essential to keep bones healthy and strong. But the opposite can also happen due to excess vitamin D. That is, bone loss can start due to hypercalcemia. In this case, bone pain and muscle tension occur.

Calcium increases if you eat too much vitamin D. This calcium filter puts extra pressure on the kidneys. If this continues for a long time, there is a possibility of calcium accumulation in the kidney tissue. As a result, kidney stones appear later. In medical terms, it is called ‘nephrocalcinosis’. In this disease, the filtering ability of the kidneys decreases day by day. Finally, the kidneys stop working.

Excess vitamin D reduces appetite. Aversion to food or feeling nauseous at the sight of food may occur. This can usually happen if you take too many supplements.

So do not buy Vitamin D supplements from the store on your own. Rather, consult a doctor who will prescribe the medicine after understanding how much vitamin you need through a blood test.
