Side Effects of Vitamin D3

Common Side Effects

You may notice some side effects of vitamin d3 when you start taking supplements, especially if you use high doses of vitamin d. Most people do not have problems, but a few may experience mild issues. The most common side effects of vitamin d include:

• Digestive problems like nausea, stomach pain, or constipation
• Headaches or dizziness
• Feeling tired or weak

In a large clinical trial, about 16.5% of people taking vitamin D3 reported at least one side effect, compared to 15.8% in the placebo group. Dizziness happened a bit more often in the vitamin D group. However, the overall risk of side effects of vitamin d3 was not much higher than with a placebo.

You should know that the common side effects of vitamin d usually go away if you lower your dose or stop taking the supplement. If you keep having problems, talk to your healthcare provider.

Serious Side Effects

Most people do not have serious side effects of vitamin d3, but taking too much vitamin d can cause real health problems. High doses of vitamin d over a long time may lead to vitamin d toxicity or vitamin d intoxication. This can cause your blood calcium levels to rise too much, a condition called hypervitaminosis or elevated blood calcium levels.

A patient developed hypercalcemia after taking 5,500 IU of vitamin D3 and 2,020 mg of calcium each day.
Another case showed that a 77-year-old man had serious problems after taking high doses of vitamin d for a long time. He developed hypercalcemia, kidney injury, and even life-threatening bleeding in his stomach.

Doctors use hypercalcemia as a sign of vitamin d intoxication, but it does not always show up right away. You should watch for any changes in your health if you take high doses of vitamin d.

Here is a table showing some serious side effects and how often they happen:

Adverse Reaction	Relative Risk (RR)	95% Confidence Interval (CI)	Frequency per 1000 individuals
Hypercalcemia	2.21	1.26–3.87	4
Increased risk of falls	1.25	1.01–1.55	N/A
Hospitalization	1.16	1.01–1.33	N/A
Hypercalciuria	N/A	N/A	N/A
Kidney stones	N/A	N/A	N/A

You can see that the risk of hypercalcemia and hospitalization goes up with high doses of vitamin d. Kidney stones and other problems may also happen if you take too much vitamin d for a long time.

Symptoms of Too Much Vitamin D

You need to know the symptoms of too much vitamin d, so you can act quickly if you notice them. Vitamin d toxicity, also called vitamin d intoxication or hypervitaminosis, can cause many problems in your body. Here is a table to help you recognize the signs:

Clinical Symptoms	Description
Gastrointestinal issues	You may have vomiting or stomach pain that keeps coming back.
Confusion and apathy	You might feel confused or not care about things as much as usual.
Polyuria and polydipsia	You may urinate more often and feel very thirsty, which can lead to dehydration.
Dehydration	Your body may lose too much water, which is dangerous.
Prevalence of VDT	Doctors do not know exactly how common vitamin d toxicity is, but it may rise with high doses.
Historical context	Vitamin d toxicity is rare, but it can cause serious health problems if not treated quickly.

If you take too much vitamin d, you may notice these symptoms. You should stop taking the supplement and see a doctor right away. Even though the rate of hospitalization for vitamin d3 overdose is low, you still need to be careful. Some reports show that people can take high doses of vitamin d for a long time without problems, but others may develop vitamin d intoxication or hypervitaminosis.

Tip: Always follow the recommended dose and talk to your healthcare provider before increasing your vitamin D3 intake. This helps you avoid the side effects of vitamin d3 and keeps you safe from symptoms of too much vitamin d.

Side Effects of Vitamin D Supplements

Comparison to Other Sources

You may wonder how the side effects of vitamin d supplements compare to those from other sources. When you take vitamin d supplements, you usually get a controlled dose. Food sources and sunlight give you smaller amounts. Most side effects of vitamin d supplements happen when you use high dose vitamin d. You might notice digestive problems, headaches, or tiredness. These symptoms often appear if you take more than the recommended amount.

Supplements from lichen, fish oil, or lanolin can all cause similar side effects. The risk of elevated calcium levels increases with high dose vitamin d, no matter the source. You should know that food and sunlight rarely cause elevated calcium levels. Supplements make it easier to take too much, especially if you do not check your dosage.

Here is a table to help you compare:

Source	Common Side Effects	Risk of Elevated Calcium Levels	Notes
Supplements	Digestive issues, headaches, fatigue	High with high dose vitamin d	Easy to overdose
Food	Rare	Very low	Hard to get too much
Sunlight	Rare	Very low	Body regulates production

If you use vitamin d supplements, you need to watch for side effects and elevated calcium levels more than with food or sunlight.

Differences and Similarities

You may see differences in the side effects of vitamin d supplements based on the source. Lichen-derived supplements suit vegans and often have fewer contaminants. Fish oil or lanolin-based supplements may cause allergies in some people. However, the main side effects of vitamin d supplements remain the same. You can experience nausea, constipation, or headaches with any type.

High dose vitamin d increases the risk of elevated calcium levels, kidney stones, and other problems. You should remember that all vitamin d supplements can cause these issues if you take too much.

• You should choose a supplement that fits your needs.
