People at higher risk for a Vitamin B12 deficiency include:

• Vegans and vegetarians (since B12 is primarily found in animal products)

• Older adults (due to reduced stomach acid production, which affects B12 absorption)

• People with certain digestive conditions (like Crohn’s disease or celiac disease)

• Individuals who have had weight loss surgery (which can reduce nutrient absorption)

• People who take certain medications
