People who follow vegan or vegetarian diets, older adults, individuals with digestive issues (like Crohns or celiac), and those taking certain medications (like metformin or acid reducers) are at higher risk of B12 deficiency
In addition, Vitamin B12 injections benefit many people with multiple health conditions, including if you have fatigue or lack of energy, a vegan or vegetarian diet, anemia, anxiety or depression, a weak immune system, slow metabolism, or poor sleep
so it should be addressed separately
If you have symptoms of deficiency or risk factors such as metformin use, speak with your GP about appropriate testing and treatment
Rapid use is recommended to ensure data accuracy
