Who should take what and why
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
