Feeling Tired or Foggy? You Might Be Low on Vitamin B12
Feeling tired, dizzy, or forgetful even after a full night’s sleep? It might not be burnout. Your body could be running low on vitamin B12 — a key nutrient your brain and body can’t do without.
Vitamin B12 keeps your energy steady, your mind sharp, and your immune system strong. It helps make red blood cells and supports healthy nerves and DNA. However, many people don’t get enough of it. Older adults, vegans, vegetarians, and those with absorption problems are especially at risk.
When B12 levels drop, your body sends warning signs. You might feel constant fatigue or dizziness, even after rest. Some people experience tingling in their hands and feet or notice muscle weakness. Others report pale skin, mood swings, anxiety, or depression. Over time, low B12 can affect memory and focus, leading to that frustrating “brain fog.”
Why Vitamin B12 Matters
Your body cannot produce vitamin B12 on its own. Therefore, it must come from food or supplements. Foods like fish, eggs, meat, and dairy are natural sources. Vegans and vegetarians can choose fortified plant-based milks, cereals, or B12 supplements to stay healthy.
How to Restore Balance
If you suspect a deficiency, ask your doctor for a simple blood test. It quickly measures your B12 levels. If they’re low, your doctor may suggest oral supplements or B12 injections for faster results. In addition, adding fortified foods to your diet can help prevent future deficiencies.
Taking small steps today can boost your energy, sharpen your focus, and protect your long-term health.
