Do I still need to take vitamin D supplements after receiving a vitamin D injection?

In general, after receiving a vitamin D injection, it may still be necessary to take oral vitamin D, or it may not—this depends on the individual situation. Specific analysis is as follows:

1. Required

If a patient has a severe vitamin D deficiency, it is recommended to continue taking oral vitamin D after the injection to maintain the body's ongoing need for vitamin D. At the same time, it is advisable to increase intake of vitamin D-rich foods in the diet, such as milk and egg yolks, to help the body better absorb and utilize vitamin D.

2. Not required

If a patient’s vitamin D deficiency is mild, oral vitamin D supplementation can be paused after the injection, allowing the body to gradually return to normal levels.

After receiving a vitamin D injection, patients should avoid leaving the hospital immediately and should remain under observation for about half an hour. If any discomfort occurs, patients are advised to seek medical attention promptly and receive standardized treatment under a doctor’s guidance, which will aid in recovery.
