When your body isn’t getting enough of the vitamin B12, it can result in fatigue, weakness, memory problems, and even nerve damage. It’s important to address this deficiency on time as it helps in many important functions in our body. You can include vitamin B12 sources to get appropriate amounts of this nutrient through your diet.
Vitamin B12 plays a key role in keeping your brain and nerves healthy. It helps produce DNA, the building blocks of your cells and is essential for making red blood cells, which carry oxygen throughout your body. You can find this vitamin in animal-based foods like meat, fish, eggs, and dairy.
Even though a deficiency of vitamin B12 can be of concern, it's often preventable and treatable. Let's explore the various sources of this essential nutrient and understand how to address any deficiency.
Sources of Vitamin B12
Vitamin B12 is an essential nutrient needed by the body to maintain healthy blood cells, nerves, and DNA production. Let’s break down the main Vitamin B12 sources that can keep your body in top shape.
Animal Products
The most natural and common way to get Vitamin B12 is through animal-based foods. Meat, dairy, and eggs are packed with this nutrient. Here are a few examples:
- Meat: Beef, lamb, pork, and poultry are all excellent sources of vitamin B12.
- Dairy: Milk, cheese, and yogurt not only provide calcium but are also good sources of B12.
- Eggs: If you enjoy eggs, you're in luck. They contain a decent amount of B12, especially in the yolk.
Fortified Foods
Not everyone consumes animal products. That's where fortified foods come in to help. Many food manufacturers add Vitamin B12 to cereals, bread, and plant-based milk. Here’s what you should look out for:
- Cereals and Bread: Certain breakfast cereals and whole-grain breads are often fortified with B12. Be sure to check the label to see if your favorite brand includes this vitamin.
- Nutritional Yeast: This is a go-to for many vegans and vegetarians. Nutritional yeast not only adds a cheesy flavor to dishes but is often fortified with B12. it’s an easy addition to meals like soups, salads, or pasta.

Dietary Supplements
Sometimes, getting enough from Vitamin B12 sources alone can be tricky. This is true if you follow a plant-based diet or have certain medical conditions. That's where supplements can be helpful:
- B-Complex Capsules: These provide a combination of all the B vitamins, including B12. These are a popular choice for those who want a well-rounded supplement.
- Standalone B12 Supplements: If you're specifically looking to boost your B12 levels, standalone supplements are available in various forms, such as tablets, capsules, and sublingual drops.

Prescription Forms
For people who are severely deficient in Vitamin B12 or who have trouble absorbing it through food or supplements, doctors may prescribe B12 injections or nasal gel. These treatments deliver the vitamin directly into your bloodstream or nasal membranes. This ensures quick absorption and a faster boost to your vitamin B12 levels.
- Injections: These are often prescribed for individuals with significant deficiencies, particularly those with conditions like pernicious anemia.
- Nasal Gel: This is a more recent option that provides a non-invasive way to increase B12 levels, making it suitable for people who may not want injections.
Your body’s need for Vitamin B12 changes as you age or during specific life stages, like pregnancy. You must understand the recommended daily intake to stay on top of your B12 needs.
Recommended Daily Amounts
- Adults: The recommended daily amount for most adults is 2.4 micrograms. This can usually be met with a balanced diet.
- Pregnant and Breastfeeding Women: Pregnant women need about 2.6 micrograms, and breastfeeding women need around 2.8 micrograms daily. This can support the health of both the mother and the baby.
- Older Adults: As you get older, your body may not absorb B12 as well, so adults over 60 may need more than the standard 2.4 micrograms or may benefit from supplements.
If you’re not getting enough of this nutrient from vitamin B12 sources, it can show itself through various symptoms. It’s important to recognize these signs early.
Symptoms of Vitamin B12 Deficiency
Let’s explore the different ways a B12 deficiency can affect your body and mind.
Physical Symptoms
One of the first signs of a Vitamin B12 deficiency is physical weakness. You might feel more tired than usual. Some other physical symptoms include:
- Pale Skin: Without enough B12, your body struggles to produce red blood cells, leading to a pale or yellowish complexion.
- Heart Palpitations: Your heart may start racing or pounding without any real reason. This is your body’s way of trying to pump more oxygen because it’s not getting enough red blood cells.
- Loss of Appetite: If you’re not feeling hungry or don’t want to consume food often, it could be due to low B12 levels.
- Weight Loss: Along with a loss of appetite, some people experience unintended weight loss when B12 is lacking.
Neurological Symptoms
Vitamin B12 is crucial for your nervous system. A vitamin B12 deficiency can affect the way your brain communicates with your body:
- Numbness or Tingling: A common neurological symptom is a feeling of pins and needles in your hands or feet. This occurs because B12 is needed to maintain the health of your nerves.
- Muscle Weakness: Over time, your muscles may feel weaker than usual, making it harder to lift objects or move around.
- Vision Loss: In rare cases, untreated B12 deficiency can damage the optic nerve, leading to blurry vision or even vision loss.
Psychological Symptoms
Vitamin B12 also plays a key role in your mental health. A deficiency can cause a variety of psychological symptoms.
- Depression: Low B12 levels are linked to depression, as the vitamin is important for brain health and mood regulation.
- Mood Swings: You might find yourself experiencing sudden shifts in mood or feeling irritable for no clear reason.
- Irritability: You can feel you’re becoming irritated by small things, leaving you feeling on edge or frustrated.
These symptoms can have a major impact on our health if not treated properly. Here is a useful guide to help you improve your psychological well-being.
Vitamin B12 deficiency can stem from a variety of causes. Certain groups may be more at risk than others. Try to understand these causes to know whether you're at risk and what steps you can take to avoid deficiency.
Causes and At-Risk Groups
Here are the main factors that can lead to a lack of Vitamin B12.
Dietary Causes
If you follow a vegan or vegetarian diet, you might be at higher risk of Vitamin B12 deficiency as B12 is mostly found in animal products. While vegetarians can get some B12 from eggs and dairy, vegans need to rely on fortified foods or supplements.
You may consider some convenient options like energy drinks from Supply6 that can make a significant positive impact on your body.
Age-related Factors
As we age, our stomachs produce less acid. Since stomach acid is necessary to release B12 from food, older adults may struggle to absorb enough B12. This is why Vitamin B12 deficiency is more common in adults over 60. For this group, supplements or fortified foods can be essential Vitamin B12 sources.
Medical Conditions
Certain medical conditions can interfere with how your body absorbs this nutrient from Vitamin B12 sources:
- Crohn’s Disease and Celiac Disease: These conditions affect the small intestine, where B12 absorption takes place. It becomes harder for the body to absorb enough of the vitamin, even if your diet is rich in B12.
- Pernicious Anemia: This condition occurs when the body cannot produce intrinsic factor, a protein needed for B12 absorption. Without it, your body can't properly take in Vitamin B12.
Medication Interactions
Some medications can interfere with Vitamin B12 absorption. Here are a few examples:
- Heartburn Medicines: These medications reduce stomach acid, which is necessary to release B12 from food.
- Diabetes Drugs: Metformin, a common drug used to treat type 2 diabetes, has been linked to lower B12 levels in some patients.
- Chemotherapy Drugs: Certain cancer treatments can also interfere with how your body absorbs and uses Vitamin B12.
If you've been diagnosed with a Vitamin B12 deficiency, the good news is that there are effective ways to treat it. You can include Vitamin B12 sources in your diet or take supplements to get your levels back on track. In more serious cases, medical treatments may be required.
Treating Vitamin B12 Deficiency
Let’s explore the different treatment strategies.
Dietary Changes
Making changes in your diet is often the first step in addressing a Vitamin B12 deficiency. A simple way is by adding foods rich in Vitamin B12 to your diet. Here are some top sources:
- Animal Products: Meat (especially liver), fish, eggs, and dairy products like milk and cheese.
- Fortified Foods: Cereals, nutritional yeast, and plant-based milk.
Supplements
Supplements are a great option if dietary changes aren’t enough or you're unable to consume enough B12-rich foods.
- Oral Supplements: You can take Vitamin B12 in the form of capsules or tablets.
- Sublingual B12: This form of B12 dissolves under the tongue and enters your bloodstream directly.
Injections
For people with severe B12 deficiency, oral supplements may not be enough. In these cases, doctors may prescribe regular B12 injections. These are typically given in a muscle and allow B12 to bypass the digestive system entirely.
Injections are often recommended for people with pernicious anemia or conditions like Crohn’s disease that prevent proper absorption of B12 through the gut.
Regular Blood Tests
Once you begin treatment, it's important to monitor your progress. Regular blood tests can help you track your B12 levels. Blood tests measure your Vitamin B12 levels and also help doctors adjust your treatment if needed.
