Vitamin D injections are intramuscular (into the muscle) injections that provide a large dose of Vitamin D. After the injection, the muscle gradually releases the Vitamin D into the blood stream.
Studies show that after one injection, Vitamin D levels continue to rise for several weeks, and will remain improved for several months.
Vitamin D injections are ideal for people with poor intestinal absorption of fat-soluble vitamins, who are low in vitamin D. They are also helpful for people with low Vitamin D levels who are finding it difficult to attain normal Vitamin D serum levels with oral supplementation.
We use Vitamin D3, also known as Cholecalciferol. This is the form of Vitamin D that the body can use right away.
In order to get Vitamin D injections your ND needs a recent lab test confirming low Vitamin D status.
Injections are typically given in a series of 2 to 4. The initial injection is followed by a second injection 3 months later. After the second injection, you may need another one in 3-6 months. It is ideal for your Vitamin D status to be checked (blood test) just before your second injection.
If you naturopathic doctor thinks you require regular injections to maintain adequate levels, they will advise you on a return schedule. Often 1-2 injections per year, ongoing, will be adequate after the initial injections.
Testing is important to ensure we are not over supplying you with this Vitamin, as it can become toxic at excessive levels.
Intramuscular Vitamin D3 can be uncomfortable during, and for a few hours after, the injection. Gently massaging the injection site can reduce discomfort.
Existing patients can call the clinic and book a short, 15-minute visit with their ND to find out if Vitamin D3 injections are appropriate for them. Lab tests may be required before the ND will provide you with the injection.
New patients who are only interested in a Vitamin D3 injection are asked to have a short initial consultation with one of our NDs for at least 30 minutes to assess their needs and determine if this is appropriate and safe for them. We require a new patient form to be filled out prior to this appointment.
If the ND determines that it is safe and appropriate for you, and they have all the lab work they need to make this determination, then you may get your first shot in this visit. If further testing is needed, your ND may order that, and the injection can be given on a later date if deemed appropriate.
Call 250-475-1522 (ext. 2) to reach our Acacia Health Dockside clinic. Our patient care coordinators can ensure all your questions are answered.
