What will happen if you have too much Vitamin D?

Last updated on October 20th, 2022 at 07:54 am

A compilation of some of the most interesting and informative points about excess vitamin d or too much vitamin d in our body and its negative impact.

Too much vitamin D can cause your body to overdose, leading to premature death. This is because the excess vitamin D will bind to your body’s storage of calcitonin, which controls the levels of calcium in your blood. If there is too much vitamin D present, the calcitonin cannot release any calcium into the blood, causing it to build up in soft tissues and organs.

Too Much Vitamin D

Too Much Vitamin D is a blog that examines the latest research and developments on the health benefits of vitamin D. The goal of this blog is to provide readers with up-to-date information for living well.

The role of Vitamin D

Vitamin D, also known as the ‘sunshine’ vitamin, plays an important role in taking care of our overall health. Not only does it ensure the proper functioning of our immune system, but it also looks after the development of our muscle cells.

Exposure to sunlight is the best and the most natural way to increase Vitamin D levels in your body. However, eating highly nutritious foods and/or taking supplements can also help you attain the required amount of vitamin D in the body.

Signs of Vitamin D deficiency

Vitamin D provides you with wide-ranging benefits, which is why certain health problems may arise if you’re suffering from Vitamin D deficiency. Especially during the winters, when the weather could be highly unpredictable, fog-ridden and smoggy, one may find it difficult to get themselves sufficient sunlight. This may lead to fatigue and weakness, bone pain, muscle weakness, muscle aches, or muscle cramps, along with extreme mood swings.

What is Vitamin D toxicity?

Vitamin D toxicity or hypervitaminosis D is a very rare condition that signals elevated levels of vitamin D in the body. It is usually an outcome of excess intake of vitamin D supplements, which is hardly ever the case with sun exposure or eating vitamin D-rich foods.

As per experts, supplements should be taken only when extremely necessary. People living under frigid weather, with no access to sunlight, are recommended to take vitamin D supplements. Ideally, your foods can also be a substantial source of essential nutrients, but you may need an extra dose of the sunshine vitamin, which is okay.

However, much to everyone’s surprise, too much Vitamin D in the body can cause many health problems. Before it gets more complicated, you must stop taking any more supplements. That said, here are some signs that can tell you need to stop your supplementation.

What Happens if You Have too Much Vitamin D?

Too Much Vitamin D is the ultimate guide to vitamin D, chock full of everything you need to know about how it affects your health.


Vitamin D allows your body to absorb calcium, which is important for building strong healthy bones. However, excess amounts of Vitamin D in the body can lead to a condition called hypercalcemia, which shows elevated levels of blood calcium, which can cause discomforting and potentially dangerous symptoms.

Normally, the level of calcium in the body is between 8.5 to 10.8 mg/dL. When it exceeds the normal level, it could trigger gastrointestinal symptoms like nausea and vomiting, weakness, and frequent urination.

Bone pain

When there is excess calcium in the bloodstream because of high levels of vitamin D in the body, it may become difficult for the hormones to knit together the nutrient to the bones. This may lead to aching or painful bones, an increased risk of bone fractures and injuries and can cause certain changes to the posture.

Kidney problems

Hypercalcemia because of Vitamin D toxicity can also lead to kidney complications. Elevated levels of blood calcium levels can also harm the organ’s ability to concentrate urine, resulting in unusually large quantities of urination, a condition known as polyuria.

When do you need Vitamin D supplements?

Vitamin D differs from other vitamins. It is said to be a kind of hormone, in fact a steroid hormone secreted from the skin when it is exposed to sunlight.

Given that a very few foods can provide you with this essential nutrient, in the absence of sufficient sunlight, in cold winter weathers, it could become difficult to get enough vitamin D, leading to vitamin D deficiency.

This is when supplements come into play. Taking Vitamin D supplements is an effective way to meet your nutritional needs and prevent deficiency. It is easy to take and most often safe to consume. However, too much of it can also lead to various side effects and complications. Consult with your doctor after your vitamin d3 test report, before you start vitamin d supplements.
