Ensuring that you get enough vitamin D in your daily diet can help support immune health, cellular growth, and bone development. [1] While some opt for fortified foods like milk and cereals for their daily dose of vitamin D, others opt to take supplements.

Can you take too much vitamin D? Yes, you can and it can potentially harm your gastrointestinal tract, which may lead to nausea, diarrhea, vomiting, or constipation.

How can vitamin D affect bowel movements?

So, does vitamin D cause constipation? Not exactly, but constipation is often a side effect of too much vitamin D. You might be wondering “How much vitamin D should I take?” It is generally recommended to have 400 to 800 IU daily. To help you understand how vitamin D intake is related to your bowel movements, let’s break down some facts about vitamin D and your body: [1]

  • Vitamin D is fat soluble – Vitamin D is a fat soluble vitamin. This means it’s absorbed with dietary fats. From there, vitamin D is stored in your liver and other fatty tissues. A fat soluble vitamin is excreted like water-soluble vitamins. Therefore, if you get too much of a fat soluble vitamin it’s stored in your body.
  • Hypercalcemia – Is vitamin D good for bones? When you consume the right amount, vitamin D does its job—helping your body with calcium absorption for strong bones. When you get too much calcium intake, it builds up in your bloodstream. This is known as hypercalcemia.
  • Digestive problems – Hypercalcemia can lead to a host of digestive problems. You might experience nausea, vomiting, and diarrhea. Others experience the opposite end of the spectrum—constipation. If left untreated, more serious problems can occur, including renal failure and even death.

Can the right amount of vitamin D keep your digestive system on track?

While you don’t want to go overboard on vitamin D supplementation, the right amount can help keep your digestive system humming along optimally. [2] In fact, a study of 86 patients who suffered from chronic constipation found that vitamin D deficiency was one of the key contributors to their digestive troubles.

The World Journal of Gastroenterology proposed that potential links between vitamin D and chronic constipation could be tied to the increase in inflammation and poor immune response that may accompany vitamin D deficiency.

Are there other vitamins that might contribute to constipation?

A toxic amount of vitamin D might not cause your constipation. There are other vitamins that can contribute to gastrointestinal problems as well. These may include: [3]

  • Calcium – While some people can take calcium supplements without any problems, others find they experience an increase in gastrointestinal problems, including constipation, bloating, gas, and stomach cramps when taking calcium. If you’re taking both calcium and vitamin D supplement, the combination of these two might cause you some stomach distress.
  • Iron – Iron supplements are also known to cause gastrointestinal problems. Iron can be difficult to digest when taken in supplement form and constipation is a common symptom associated with excess iron. Your healthcare provider may recommend a stool softener to relieve the discomfort caused by an iron supplement.

Constipation may also derive from causes outside of diet and supplement intake, such as:

  • Dehydration
  • Certain medications
  • Insufficient dietary fiber intake
  • Stress
  • Lack of exercise
  • Genetic predisposition
  • Colon problems

You should always consult with your healthcare provider if you’re experiencing constipation. They can rule out more serious issues and help you mitigate gastrointestinal discomfort.

What other side effects might come with vitamin D?

Constipation isn’t the only side effect associated with toxic vitamin D intake. In addition to gastrointestinal distress, excessive vitamin D intake may also lead to:

  • Loss of appetite
  • Excessive thirst and dehydration
  • Frequent urination
  • Muscle weakness
  • Pain
  • Confusion
  • Kidney failure
  • Irregular heartbeat
  • Death

On the other hand, too little vitamin D can also lead to: [4]

  • Bone deformities in children
  • Bone aches
  • Muscle weakness

Get in tune with your vitamin D levels with Everlywell

Your body requires a delicate balance of vitamins to function optimally. Too much or too little of necessary nutrients, such as vitamin D, can cause significant health problems.

That being said, when you intake excess or toxic levels of vitamin D, you may experience constipation, in addition to other digestive problems, loss of appetite, and muscle weakness.

If you’re uncertain if your vitamin D levels are where they should be, Everlywell can help. Our at-home Vitamin D Test is an easy and convenient way to check your vitamin D from the comfort of your home. Also note that you can now purchase vitamin D supplements directly from Everlywell. If you’re experiencing various bowel-related symptoms, consider taking an at-home colon cancer test.

Why vitamin D deficiency is dangerous and how to diagnose it




“For most people, vitamin D is linked to the bones – it was given to children in the form of fish oil to prevent rickets, and TV commercials recommend it to the elderly to protect them from osteoporosis. It turns out that it is valuable, not only for this.

Vitamin D regulates the absorption of calcium and phosphorus minerals, their blood levels and their entry into bone tissue and teeth. Together with vitamin A and calcium or phosphorus, it protects the body from colds, diabetes, eye and skin diseases. It also helps prevent dental caries and gum disease, helps fight osteoporosis, and speeds up the healing of fractures.

Determination of vitamin D level is used for: Diagnosis of disorders of calcium metabolism (with rickets, pregnancy, malnutrition and digestion, hyperparathyroidism, osteoporosis).

Vitamin D analysis is performed to diagnose hypo- and beriberi, as well as a number of chronic diseases associated with a lack of this substance in the body. The procedure belongs to general clinical trials.

Why is it important to test for vitamin D?

Vitamin D maintains the level of inorganic phosphorus in the blood, prevents muscle weakness, improves the body’s immunity, affects the cells of the intestines, kidneys and muscles, is involved in the regulation of blood pressure and heart function.

Vitamin D is essential for the functioning of the thyroid gland and normal blood clotting.

Vitamin D affects the absorption of calcium and magnesium, kidney function, susceptibility to skin diseases and heart disease.

Vitamin D blocks the uncontrolled reproduction of body cells, which makes it effective in the prevention of cancer (cancer of the breast, prostate, colon, pancreas, esophagus, ovaries, uterus, stomach and a number of other tumors).

Main symptoms of vitamin D deficiency/overdose

Vitamin D overdose causes the following symptoms:

  • weakness
  • loss of appetite
  • nausea
  • constipation
  • diarrhea
  • sharp pains in the joints
  • headaches and muscle pains
  • fever
  • increased blood pressure
  • convulsions
  • slow pulse
  • shortness of breath
  • development of osteoporosis
  • bone tissue demineralization
  • deposition of calcium salts in organs, hindering their functions

Vitamin D deficiency symptoms

In the early stages, vitamin D deficiency manifests itself in the form of the following symptoms:

  • loss of appetite
  • insomnia
  • burning in mouth and throat
  • weight loss
  • blurred vision

Further development of osteoporosis is observed. And in children it is rickets, spinal deformities, growth and developmental delay.
