Tag: Injections vs supplements

According to some data, around one in four people in the United States may be vitamin D deficient. For those experiencing symptoms like fatigue and low mood, it raises the important question: will a vitamin D injection make me feel better? The answer is complex and depends heavily on the root cause of your symptoms.

According to scientific studies, the bioavailability of vitamin injections is significantly higher than that of oral supplements, with some estimates suggesting up to 100% absorption for injections versus as low as 20-50% for pills. This difference is at the core of the debate over whether injections are better than supplements for delivering essential vitamins and minerals.
