Vitamin B12 shots work faster than any oral supplement
For patients diagnosed with a vitamin B12 deficiencyespecially when caused by problems with absorption in the digestive tract (such as pernicious anemia, certain gastrointestinal conditions, or after specific surgeries)oral supplements may not be effective
It is not a routine prenatal supplementation method but rather a therapeutic intervention for specific needs
For example, while the injection covers B, B, B, B, B, you still need other vitamins (like vitamin C, B folate, B if not supplemented separately, etc.) and minerals (iron, zinc, etc.) from food
Any excess is typically excreted in the urine, lowering the risk of toxicity
