Vitamin D overdose!? I didn’t know that this was possible. I live in the top of the United States and rarely travel to warm, sunny places.
I’ve written many posts on PeopleBeatingCancer.org extolling the benefits of vitamin D while cautioning readers about the risk of vitamin D deficiency.
I’ll try to clarify what I mean when I talk about too much vitamin D in our system.
It’s important to understand that you can’t figure out the above blood levels by supplementing (taking vitamin D supplements). You have to have your blood levels checked. I go to my local CVS but you can go to your doctor probably.
Supplementing with vitamin D can have both benefits and potential drawbacks. Here are some of the pros and cons associated with vitamin D supplementation:
It’s important to note that before starting any new supplement regimen, it’s advisable to consult a healthcare provider, especially if you have underlying health conditions or are taking medications. They can provide personalized recommendations based on your specific health needs and circumstances. They can also monitor your vitamin D levels through blood tests to ensure you are not taking too much or too little.
Here is another interesting aspect of vitamin D supplementation. It is cheap. And easy. But remember that you and UNDER do it and you can OVER do it. So get your blood checked regularly.

“Vitamin D toxicity, sometimes called a vitamin D overdose, is a rare but potentially dangerous condition. It occurs when someone has too much vitamin D in their body. Vitamin D toxicity is also called hypervitaminosis D.
A vitamin D overdose is typically a side effect of taking large doses of vitamin D supplements.1 It would not occur because of direct sun exposure or diet…
The common types of vitamin D received from your diet are D2 (ergocalciferol) and D3 (cholecalciferol). They play the same role in the body but come from different sources. Vitamin D2 comes from plant sources, while vitamin D3 comes from animal sources. Vitamin D3 has been found to bind more effectively, making it a stronger source, which allows for lower doses with the same health benefits.4

Many of the causes of vitamin D toxicity are a consequence of inappropriate prescribing, not taking vitamin D as prescribed, and the use of high-dose and unlicensed preparations.2 Many cases are preventable with appropriate use, proper formulation, and avoidance of unlicensed products.
Excessive effects of vitamin D can lead to higher calcium levels in the blood—a condition called hypercalcemia. It is often diagnosed at an early stage during routine blood work.5
Most people with hypercalcemia will not have symptoms. But, symptoms can occur in people who have taken high doses of vitamin D for a long time or in someone who has taken an extremely high dose over a short time…
Higher doses are typically prescribed to people whose bodies do not adequately process vitamin D due to some health conditions.6 Such conditions include asthma, psoriasis, rheumatoid arthritis, rickets, and tuberculosis. The higher dose is often prescribed to correct or prevent deficiency…
Vitamin D is vital to helping you to stay healthy. But even without underlying health conditions, you may need supplements to achieve optimal levels.
While it is rare, it is possible to experience vitamin D toxicity, which shows up as hypercalcemia. Common signs of hypercalcemia include digestive problems, fatigue, appetite loss, frequent urination, high blood pressure, and heart abnormalities. Complications of hypercalcemia are an altered mental state and kidney problems.
Vitamin D toxicity is more common in people who have medical conditions where it is necessary to prescribe higher supplement doses. To reduce your risk, avoid high doses and do not start taking supplements without approval from a healthcare provider.
If you are on a higher dose prescribed by a healthcare provider, you should report side effects and get your blood work tested regularly. “
