Not commonly used, Vitamin D injections send the nutrient directly to the bloodstream. Doctors provide these injections to patients, either on a monthly basis or as required. The most suitable use of injections exists for:

People with severe vitamin D deficiency

Those who cannot absorb vitamin D from food or pills (due to digestive disorders or certain surgeries)

Individuals who need a rapid and reliable increase in vitamin D levels

Advantages:

Fast and effective, especially for severe deficiencies

The treatment works through bypassing the digestive system which makes it beneficial for people with absorption difficulties.

Less frequent dosing (monthly or longer intervals)

Who Should Avoid Injections

People who do not have a diagnosed deficiency

Those who are pregnant or trying to conceive, unless advised by a doctor
