11. Heart Palpitations
People with B12 deficiency may experience heart palpitations or a racing heart. This is linked to anemia caused by low levels of B12, which affects the blood’s ability to carry oxygen.
Who is at risk for B12 deficiency?
Older adults: Absorption of B12 decreases with age.
Vegans and vegetarians: B12 is primarily found in animal products, so those who avoid meat, dairy, and eggs may be at risk.
People with digestive issues: Conditions like celiac disease, Crohn’s disease, and those who have had weight-loss surgery can impact B12 absorption.
People taking certain medications: Some medications, such as proton pump inhibitors, can interfere with B12 absorption.
If you notice any of these signs or suspect you may be deficient, it’s important to see a doctor. A simple blood test can determine if your B12 levels are low, and your doctor can recommend supplements or dietary changes to address the deficiency.

Have you experienced any of these symptoms, or do you know someone who might be at risk for B12 deficiency?
