Causes and Risk Factors of Vitamin B12 Deficiency
Vitamin B12 deficiency happens for many reasons and is affected by various risks. Knowing these can help stop and treat B12 deficiency.
Dietary Factors
Not eating enough B12 foods is a big reason for being low on vitamin B12. B12 is mainly in foods like meat, fish, eggs, and dairy. This means people who don’t eat these, like vegetarians or vegans, might lack B12.
| Age | Recommended Daily Dosage of Vitamin B12 (mcg) |
|---|---|
| Newborns (0-6 months) | 0.4 |
| Infants (7-12 months) | 0.5 |
| Toddlers (1-3 years) | 0.9 |
| Toddlers (4-8 years) | 1.2 |
| Adolescents (9-13 years) | 1.8 |
| Teenagers (14-18 years) | 2.4 |
| Adults (unless pregnant or breastfeeding) | 2.4 |
Other Causes and Risk Factors
Besides what you eat, there are more things that can lead to low B12:
- Health issues that impact absorbing nutrients like Crohn’s, celiac, and certain surgeries.
- As people get older, they might struggle more with B12 because they make less stomach acid and can’t absorb it well.
- Some drugs might lower B12 absorption, such as aminosalicylic acid and certain heartburn medicines.
- Pernicious anemia, a condition where your immune system attacks cells that make B12, is the biggest reason for B12 problems in the U.S.
- Some people have genes that make it hard for their body to use B12, which can also cause a deficiency.
It’s key to spot and deal with these reasons and risks to stop B12 deficiency. If you worry about your B12 or fit in these groups, talking to a doctor is important for the right advice.
Physical Symptoms of Vitamin B12 Deficiency
Vitamin B12 deficiency can show up in many ways. A shortage of B12 often leads to a type of anemia called megaloblastic anemia. This can cause fatigue, weakness, and feeling out of breath when doing things. Having pale skin is a common sign of this type of anemia.

Not having enough red blood cells can make your skin look paler than usual. This means less oxygen is getting around, making you look kind of washed out.
Other signs can include feeling dizzy, having trouble breathing after you exert yourself, a swollen tongue, or gums that bleed. You might also get mouth sores, feel sick to your stomach, throw up, or have a fast heartbeat. These signs can vary in how strong they are but are important to address.
