You might be a good candidate if you have confirmed low B12 levels (from lab work), follow a strict vegan/vegetarian diet, have digestive issues reducing B12 absorption (e.g., after gastric surgery, or with conditions like Crohns), or experience chronic fatigue and other symptoms linked to B12 deficiency
Choosing the right shot depends on your health goals, current diet, lifestyle, and any lab results or deficiencies
These symptoms are usually temporary and can often be managed by taking the supplement with meals or adjusting the dose
Vitamin B12 is sometimes added to support nerve health, which is important because people with diabetes have a higher risk of nerve damage
Other contributing factors may include stress, dietary changes, or concurrent medications
UK guidance suggests that older adults with unexplained neurological or haematological symptoms should be tested for B12 deficiency
