Don't Ignore Fatigue: Vitamin B12 Deficiency Signs, Risks & Solutions

• Vitamin B12 (cobalamin) is vital for DNA synthesis, red blood cell production, neurological function, and energy metabolism.
• Early deficiency signs are often subtle, including persistent fatigue, tingling, "brain fog," pale skin, memory lapses, and mood changes.
• High-risk groups include vegans, older adults, individuals with digestive conditions like Crohn's or celiac disease, and those on certain medications.
• Natural sources are animal products; fortified foods are key for vegetarians/vegans. Adults need 2-2.4 micrograms daily.
• Early diagnosis through blood tests and treatment with dietary changes or supplements (tablets, injections) are crucial to prevent serious complications.
