Does Vitamin B12 Help With Fatigue?

Key points: 

  • Vitamin B12 is one of the essential vitamins that help keep our bodies healthy and energised. Supplementing your diet with this vitamin may help to boost energy levels, improve cognitive function, enhance haemoglobin production, lower the risk of anaemia, promote hair growth, and improve your mood.
  • Vitamin B12 deficiency can cause many symptoms, such as fatigue, muscle weakness, low blood pressure, mood swings, shakiness, muscle stiffness, muscle spasticity, and incontinence. Megaloblastic anaemia is also a serious condition that results from a lack of vitamin B12.
  • Eating foods like beef, poultry, fish, eggs, and dairy products, as well as fortified breakfast cereals, is the simplest way to increase your levels of vitamin B12 naturally. Combining a healthy diet with supplements can help you get even better results. 

If you’re feeling low in energy, you may need a vitamin B12 boost. Vitamin B12 is one of the best cures for fatigue, and it is also one of the best supplements to keep the body healthy. In this article, you’ll find out how vitamin B12 can increase your energy levels and learn about the best sources of this nutrient. 


Does Vitamin B12 Increase Energy Levels?

While scientists are not 100% certain that vitamin B12 is responsible for giving your body energy, there’s a definite link between how the body produces energy and its levels of B vitamins, including vitamin B12. But it doesn’t necessarily mean that vitamin B12 supplements will keep you energised. 

The truth is that your body takes energy from the calories you consume, particularly food high in carbohydrates. Carbohydrate-rich foods contain glucose or, in simple terms, sugar which our cells convert into adenosine triphosphate (ATP). This is the molecule that gives the cells and our body energy to function. 

Vitamin B12 helps your body convert glucose into ATP molecules by speeding up chemical reactions. It basically helps to metabolise sugar into energy. Getting a proper amount of vitamin B12 daily not only helps to keep you energised but also prevents symptoms like insomnia and fatigue, which are typically caused by vitamin B12 deficiency. 


Other Vitamin B12 Benefits

Besides boosting your energy levels, vitamin B12 also promotes the growth of new red blood cells, which carry oxygen throughout the body. It also improves muscle health since the oxygen delivered by red blood cells helps the muscles grow. Studies have found that vitamin B12 may also reduce muscle weakness and cramping associated with a vitamin B12 deficiency. 

Fatigue, which is a common symptom of vitamin B12 deficiency, directly impacts performance, which means that supplementing with this vitamin may also help with memory and concentration.

If you have mood swings, vitamin B12 may help keep you in a balanced mental state. Agitation and irritability are also common symptoms of a vitamin B12 deficiency. This vitamin can also promote hair growth, as the red blood cells carry oxygen to the hair follicles as well. 

We also need vitamin B12 to produce elements of DNA, regenerate bone marrow and the lining of the gastrointestinal and respiratory tracts, keep the nervous system healthy, and prevent megaloblastic anaemia. 

Older adults can reduce the risk of heart attack and stroke, prevent Alzheimer’s disease, and improve their balance by taking vitamin B12 supplements. 


Risks Of Vitamin B12 Deficiency

Although many people get enough vitamin B12 from their diets, people with the following conditions are more prone to vitamin B12 deficiency:

  • Celiac disease
  • Crohn’s disease
  • Individuals with immune dysfunction
  • HIV
  • Individuals with a history of bowel disease
  • Individuals on prescription antacids, anti-seizure medications, colchicine, or chemotherapy medications
  • Vegans and vegetarians
  • Those who drink alcohol regularly

The most common symptoms of vitamin B12 deficiency are fatigue, muscle weakness, low blood pressure, and mood swings, but shakiness, muscle stiffness, muscle spasticity, and incontinence are often present as well. Of all the conditions linked to vitamin B12 deficiency, megaloblastic anaemia is the most serious one. This is a chronic blood disorder in which the bone marrow produces large and immature blood cells. This results in the body lacking healthy red blood cells to transport oxygen.

How Much Vitamin B12 Should You Take

The general recommendation for people between the ages of 14 and 50 is to take 2.4 micrograms of vitamin B12 daily. While most people get enough vitamin B12 from their diets, you can always benefit from supplementing with it. Taking vitamin B12 is especially recommended for people who are over 50 since, with age, we tend to lose stomach acid, which makes it more difficult for our bodies to absorb vitamins from food. Vegans and vegetarians can also benefit from vitamin B12 supplements, as this vitamin is mostly found in animal products, including fish, poultry, eggs, and red meat. 

How To Boost Vitamin B12 Levels

The easiest way to naturally boost your vitamin B12 levels is by eating common foods, such as beef, poultry, fish, eggs, and dairy products. Products like tuna, steak, clams, salmon, fortified nutritional yeasts, and fortified breakfast cereals are particularly rich in vitamin B12.

If you're looking to improve your energy levels with vitamin B12, you should consider using a combination supplement for even better results.
