What is Vitamin B12?
Vitamin B12, also called cobalamin, is a water-soluble vitamin that plays a key role in keeping your body’s nerves and blood cells healthy. It also helps make DNA, the genetic material in all of your cells.
Your body does not make vitamin B12 on its own. You have to get it from food or supplements. If you are not getting enough of this vitamin, the symptoms can creep in quietly but affect your health in a big way over time.
Why is Vitamin B12 So Important?
Vitamin B12 has many vital roles in your body. Here are some of the key benefits:
- Supports energy production: B12 helps convert the food you eat into energy. If you feel drained even after a full night’s sleep, low B12 could be a factor.
- Keeps your nerves healthy: It maintains the protective covering (called the myelin sheath) of your nerves, preventing damage and related symptoms like numbness or tingling.
- Helps make red blood cells: B12 is essential in producing red blood cells. Without enough, you can develop anaemia.
- Boosts brain function: It supports memory, focus, and mood balance.
- Supports heart health: It helps reduce levels of homocysteine, an amino acid linked with heart problems when it builds up in the body.
Who is Most at Risk of B12 Deficiency?
B12 deficiency can affect anyone, but some people are more at risk. These include:
- People over 60, as the ability to absorb B12 naturally reduces with age
- Vegans and vegetarians, since B12 is mostly found in animal products
- Those with digestive issues like Crohn’s disease or coeliac disease
- People who have had weight loss surgery or other stomach surgeries
- Long-term users of certain medicines such as antacids or metformin
B12 Deficiency Symptoms
B12 deficiency can show up in many ways, and symptoms often appear slowly. Some common B12 deficiency symptoms include:
- Constant tiredness or fatigue
- Pale or yellowish skin
- Pins and needles or numbness in hands and feet
- Muscle weakness
- Trouble walking or maintaining balance
- Memory loss or confusion
- Mood changes like depression or irritability
- Swollen or sore tongue
- Breathlessness or dizziness
If you notice any of these signs, it’s important to speak to one of our pharmacists. They can guide you on testing your B12 levels and choosing the right supplement or treatment.
Vitamin B12 Food Sources
Now that we know how important B12 is, let’s look at where you can find it naturally. Most vitamin B12 food sources are animal-based, which is why vegetarians and vegans need to pay special attention.
Here are some common B12 rich foods:
- Liver and kidneys (especially lamb liver)
- Fish like salmon, sardines, tuna, and trout
- Meat such as beef and chicken
- Eggs and dairy products like milk, cheese, and yoghurt
- Fortified breakfast cereals (look for B12 on the label)
- Plant-based milks (like soy, oat, or almond) that are fortified with B12
If you follow a plant-based diet, always read food labels and choose options that are fortified with B12.
What If You Don’t Get Enough from Food?
Sometimes, food alone may not provide enough B12, especially if you have absorption issues or dietary restrictions. That’s where B12 supplements come in.
B12 supplements in the UK are available in several forms, including:
- Tablets or capsules
- Sublingual drops or sprays (placed under the tongue)
- Injections (usually given if you have severe deficiency or absorption issues)
The type and dosage can vary depending on your needs. Our pharmacists can recommend the best option for you based on your health, diet, and lifestyle.
How is B12 Deficiency Diagnosed?
A simple blood test can check your B12 levels. If your symptoms suggest a deficiency, our team can arrange or guide you on getting tested. In some cases, additional tests might be needed to understand the root cause of the deficiency, such as whether it is due to low intake or poor absorption.
Can Too Much B12 Be Harmful?
The good news is that vitamin B12 is considered safe, even at higher doses, because it is water-soluble. This means any excess is usually passed out of the body in urine. However, there is no need to overdo it, as the body only uses what it needs.
Tips to Maintain Healthy B12 Levels
Here are some simple tips to keep your B12 levels in check:
- Include B12 rich foods in your daily meals.
- Choose fortified products if you are on a plant-based diet.
- Get regular blood tests if you are in a high-risk group.
- Speak to our pharmacists before starting supplements.
- Be consistent with your B12 intake, especially if using supplements.
Stay Energised and Sharp with the Right B12 Support
Vitamin B12 might be a small nutrient, but it has a big impact on your energy, brain health, and overall wellbeing. If you are feeling unusually tired, forgetful, or moody, it might be worth checking your B12 levels.
Luckily, there are plenty of ways to boost your intake through food or supplements.
