Vitamin B12 injections 
 
Vitamin B12 helps your body use fat and carbohydrates for energy and make new protein. It is also important for normal blood, cells, and nerves.

VITAMINS OUR BODY NEEDS

Most people have very busy lifestyles, and find it very difficult to find time for themselves. Due to this, many of us are unaware that we are deficient in essential vitamins and minerals. Deficient levels of vitamin B12 can quickly make people aware that their health is at risk. B12 plays an integral role in many functions of the body.

Vitamin B12 is water-soluble, your body does not store it and many of us are susceptible to not getting enough B12 in our diets. Luckily, people can receive their B12 through foods such as meat, fish, eggs and dairy products. If you do not already receive the B12 injection

What is a B12 injection?

A B12 injection sometimes referred to as a "shot" delivers a high dose of therapeutic B12, this is usually in the form of cyanocobalamin or hydroxocobalamin. In situations where a higher dose is needed or where injections are the only option, the B12 shot is used.

Sometimes B12 shots are also used as an energy booster since B12 plays a critical role in cellular energy production.

 

Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.

Vitamin B12 binds to the protein in the foods we eat.

In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form.

Reasons why someone may have a B12 injection

Vitamin B12 injections are used to treat lower levels of this vitamin in the body, this is often referred to as a deficiency. B12 helps your body use fat and carbohydrates for energy and make protein. It also has an important role within the blood, cells and nerves. Most people should get enough B12 through the oral intake of their diet, but a deficiency may occur due to certain health conditions such as gastrointestinal disorders, cancers, hereditary issues or general poor nutrition. B12 injections are administered most often to people that have genetic conditions that block absorption and people with the disorder Pernicious Anaemia. Pernicious anaemia is caused by a decrease in red blood cells when the body cannot absorb enough vitamin B12, greatly increasing the risk of neurological complications.

About B12 Deficiency

Vitamin B12 deficiency is believed to be one of the most common nutrient deficiencies in the world. Vitamin B12 deficiency can be more common in people that take anti-biotics frequently, those that are on stomach acid altering medications, elderly people and sometimes those that follow a vegetarian or vegan diet. When someone is B12 deficient they can sometimes need B12 injections to offset the many symptoms of vitamin B12 deficiency, such as fatigue and weakness, poor moods, and low concentration. 

Vitamin B12 deficiency can also have more serious effects in some people. B12 deficiency can disturb red blood cell formation and elevate homocysteine levels, which negatively impacts neurological and cardiovascular health, in addition to posing risks during pregnancy.

Signs and symptoms of a B12 deficiency

Some of the common symptoms of vitamin B12 deficiency include low mood disorders and depression, fatigue and generalised tiredness, memory failure, alongside low blood pressure and anaemia. The B12 injection may be used to boost energy, as a therapy for low mood and depression, or to drive cognitive function. Research is currently taking place to address B12 injections for other problems, such as bipolar disorder, shaky leg syndrome and autism.

What does B12 actually do?

Vitamin B12 is a crucial for many vital metabolic and hormonal functions. This includes the production of digestive enzymes and carrying important nutrients in and out of cells. Some of the roles of vitamin b12 are:

  • Forming red blood cells

  • Playing a role in DNA/RNA synthesis 

  • Acting as a cofactor for methionine synthase (helping with methylation or the conversion homocysteine to methionine, which protects cardiovascular health and more)

  • Facilitating metabolic conversion of protein and fats

  • Carrying out neurotransmitter functions and helping with the production of hormones

  • Helping convert amino acids and make creatine 

  • Producing myelin sheath (the coating of the nerves)

  • Helping the synthesis of haemoglobin

  • Playing a role in foetal development during pregnancy 

Benefits of vitamin B12

Can improve mood – Various studies have shown that regular doses of B12 can prevent depression, restore bettermood control, and retain healthy memory/mental function. 

Helps Lower Fatigue – Restoring B12 to healthy levels can treat anaemia, help with conversion of macronutrients and production of creatine (beneficial for building muscle mass), and reduce muscle weakness.

Can help improve your metabolism – Vitamin B12 injections can help improve a sluggish metabolism and can even help with weight loss. As the injections may give people more energy and regulate hormone production, it is possible to experience changes in appetite, improve sleep and better exercise performance. Some even claim B12 injections improve appearance of their skin, hair, and nails. 

Protects the Heart – Elevated homocysteine levels have been identified as a risk factor for cardiovascular disease. B12 is needed for the conversion of homocysteine and therefore can prevent conditions or complications like heart attack, stroke, or coronary heart disease. 

Improves low sperm count and boosts sperm mobility - Vitamin B12 plays an important part in the production and development of sperm. If you are deficient or low in B12, it can affect your sperm health. B12 is recommended when sperm count is affected. Vitamin B12 can also help with poor sperm motility

May Prevent Loss of Libido – due to the fact a lack of vitamin B12 can result in pernicious anaemia, one of the symptoms is loss of libido, therefore regular doses of B12 can help to prevent this.
