That said, excessive sunlight can damage your skin, so you should always exercise caution when going out in the sun for extended periods. Remember to wear sunscreen or protective clothing if you plan to spend extended periods in the sun.

Vitamin D shots and IV infusions

Sometimes vitamin D shots and infusions are recommended for patients with dangerously low vitamin D levels and need to increase them quickly.

  • Vitamin D shots are intramuscular injections into a muscle (usually that of the upper arm or thigh), similar to a flu shot. Vitamin D injections may occur multiple times per year, but this amount can vary depending on specific needs.
  • A vitamin D infusion requires intravenous administration with an IV line placed in the vein. The vitamin D is then infused through a small tube into this line, delivering the supplement directly to the bloodstream.

Generally, vitamin D infusions and shots are a quick, complete, and effective way to increase vitamin D levels compared to oral supplements because oral supplements have to pass through the digestive tract before absorption.

It’s important to speak to your doctor before choosing a vitamin D supplement to help avoid side effects or interactions with any medications you are taking.

Vitamin D Shots - Frequently Asked Questions

Can you take too much vitamin D?

Yes, it is possible to take too much vitamin D. Vitamin D is a fat-soluble vitamin, which means that it can build up in the body and potentially lead to toxic levels if it is consumed in large amounts. Vitamin D toxicity can cause hypercalcemia, a buildup of calcium in your blood. This condition can cause symptoms such as weakness, nausea, vomiting, frequent urination, kidney problems, and more.

How often do you need vitamin D shots?

Frequency of treatment depends on individual circumstances such as the severity of vitamin D deficiency, medical history, and other factors. However, most people may receive 1 – 3 shots over the course of a year.

Are vitamin D shots better than oral supplements?

Yes. Because vitamin D shots are given intramuscularly, the ingredients bypass your digestive system so that the full dose is available to your body for maximum benefits. Vitamin D shots are rapidly available for your cells to use.

What happens if you don’t treat vitamin D deficiency?

Not treating vitamin D deficiency can cause rickets, a rare but treatable condition that causes fatigue, frequent illnesses, depression, and impacts bone and muscle health. In children, vitamin D deficiency can impact normal growth and development.
