When it comes to supplementation, people most commonly ask can you overdose on Vitamin D? This is an essential nutrient which is also referred to as “the sunshine vitamin”. More interestingly, our body produces it after having exposure to sun rays.
What’s more, Vitamin D is usually present in a few food sources. Moreover, a wide range of fortified foods also includes it. Furthermore, people often consume it in the form of additional dietary supplements. Wondering why? Simply for the purpose of catering to the needs of their body.
What Is Vitamin D Essential For?
- Calcium Absorption: As you might already know, Vitamin D plays a major role in the proper absorption of calcium in our body. Also, it works against the release of parathyroid hormone in the body. PTH causes the reabsorption of bone tissue, making the bones brittle, thin, and weak. As a result, Vitamin D is necessary for bone growth and maintenance.
- Functioning of Immunity: Additionally, Vitamin D is essential for the proper function of the immune system, as well as the muscles. Also, it aids in protecting the body against various illnesses and infections.
- Prevention of Chronic Diseases: In addition to this, the D complex also plays a vital role in the prevention of various chronic diseases. According to various researches, vitamin D is known to reduce the risk of prostate, colon, and breast cancers.
It also helps in the prevention and treatment of diabetes, high blood pressure, heart disease, as well as multiple sclerosis.
- Rickets Prevention: The deficiency of Vitamin D is commonly linked with rickets in children. Severely low levels of this nutrient also cause brittle and soft bones, muscle pain, bone pain, and weakness. It may also cause an increase in the risk of developing cardiovascular diseases in adults. Moreover, Vitamin D can be helpful in prevention against another type of cancer.
Food Sources of Vitamin D
As already discussed above, our skin creates Vitamin D through interaction with ultraviolet sun rays. This process is known as vitamin D synthesis. In fact, this is our body’s natural way of producing Vitamin D.
However, the essential nutrient is also present in many food sources, both natural and fortified. Such as
- Cod Liver Oil
- Egg Yolk
- Fortified Orange Juice
- Fortified Cereal
- Fortified Milk
- Fortified Yoghurt
Apart from this, you can also consume Vitamin D through additional supplements that are easily available in the market.
Overdosage of Vitamin D – Causes
Regarding the intake of essential nutrients, you should know about the outcomes of both the deficiency and the toxicity. Just like too little Vitamin D causes numerous diseases, its overdosage can also be harmful to the body.
Oftentimes, the toxicity of Vitamin D is known as hypervitaminosis D. Although it is a rare condition, it could lead to serious and dangerous results. Nonetheless, the toxicity of Vitamin D is only caused due to an increased intake of additional Vitamin D supplements.
In other words, an individual’s diet or sun exposure doesn’t lead to an increase in Vitamin D’s amount. In addition, foods fortified with Vitamin D also don’t contain the nutrient in amounts that are too high.
However, it is important to know that the overdosage of Vitamin D only rarely occurs.
Who is at Risk of Vitamin D Toxicity?
Individuals who consume high-dose supplements for a long period of time are at risk of developing Vitamin D toxicity. Specifically, if they do so without monitoring their blood levels.
In addition to this, it is also possible to consume excessive amounts of Vitamin D accidentally. This happens when the supplements being consumed contain high Vitamin D amounts than the amount listed on the label.
So, make sure that you consult a dietitian about how much Vitamin D should you take. Also, avoid consuming too many supplements without recommendation.
Overdosage of Vitamin D – Effects
Let’s talk about the side effects that the overdosage of Vitamin D can cause.
Hypercalcemia: Firstly, the presence of excessive Vitamin D amounts in the body leads to calcium’s accumulation in the blood. This condition is referred to as hypercalcemia. Let’ have a look at its possible symptoms:
- Frequent Urination
- Stomach pain
- Diarrhea or constipation
Other than this, it may also result in the formation of calcium stones in the kidney and pain in bones. Furthermore, it also causes elevated levels of blood, leading to slurred speech and forgetfulness. What’s more, bone loss may also occur as a result of Vitamin D toxicity.
Astonishingly, Vitamin D toxicity’s effects could last for several months even after you restrict your intake of the supplements. This is due to the fact that the nutrient is stored in the body fat and then slowly into the blood.
So, How to Flush Vitamin D Out of the System?
It is important to know how to get rid of too much Vitamin D. Because, as stated above, a high dose of Vitamin D can lead to various side effects.
The treatment of Vitamin D toxicity includes stopping the intake of all sorts of Vitamin D supplements. In addition, it is also recommended to eliminate the food sources that contain high amounts of Vitamin D.
Doctors also often prescribe intravenous fluids and other medications, such as bisphosphonates or corticosteroids.
So, ensure that you don’t take too much Vitamin D on a daily basis.
What’s the RDA of Vitamin D?
The Recommended Dietary Allowance (RDA) of Vitamin D is less than 4000 IU per day. However, higher dosages may not affect healthy adults much.
Still, make sure to monitor your blood levels if you are regularly consuming Vitamin D supplements. In addition, you can reduce your risk of accidental overdose by buying supplements from well-known manufacturers.
The Bottom Line
All in all, the excessiveness of everything is bad. Although Vitamin D is necessary for maintaining good health, its overdosage can lead to serious side effects. Thus, it is always best to consult a professional dietitian before adding Vitamin D supplements in your daily dietary intake.
