Certain groups are more likely to suffer from vitamin B12 deficiency, including:
People over 60 (due to reduced stomach acid production)
Vegans and vegetarians (B12 is mainly found in animal products)
People with digestive disorders (such as Crohn’s disease or celiac disease)
People who take certain medications (such as metformin or acid reducers)

If you’re experiencing any of the above symptoms — especially if you fall into one of the higher risk categories — it’s a good idea to talk to your doctor. With a simple bl00d test, you can check your vitamin B12 levels.
Final Thoughts
Vitamin B12 may not get as much attention as other nutrients, but its effects on the body and mind are significant.y.
1. Fatigue and weakness
One of the earliest and most popular effects of a B12 deficiency is the constant feeling of sadness or weakness. This happens because without enough B12, your body can’t make enough healthy red bl00d cells.
Buy vitamins and supplements
2. Pale or yellowish skin
If your skin looks unusually pale or has a slight yellow tinge, it could be due to a lack of vitamin B12. This condition occurs when red bl00d cells break down more easily (a process called hemolysis) and release bilirubin, which gives the skin a yellowish appearance.
3. Shortness of breath and dizziness
When red blood cell counts drop, your body struggles to get enough oxygen to your tissues, leading to shortness of breath — especially during physical activity. You may also experience dizziness or lightheadedness, especially if you get up quickly.
