Vitamin B12 injections are becoming more in demand as people become aware of the many benefits, as well as the link between a lack of Vit B12 and various associated ailments or illnesses. Vitamin B12 Injections are the best way of rapidly boosting your levels, having an almost instant impact on your health and wellbeing 

Vitamin B12 is vital for the adequate functioning of our digestive system and defends us against harmful viruses and bacteria. Vit B12 deficiencies affect the way in which our bodies use valuable energy. Stress, fatigue and ‘brain fog’ as well as reduced physical stamina are common side effects of vitamin B12 deficiency. The benefits of vitamin B12 injections in the treatment of these, as well as serious issues including dementia and panic disorder, have come to light within the past twenty years. Recently, the increasing popularity of veganism has made B12 shots more popular than ever before.


Vitamin B12 injection benefits include a healthier cardiovascular system, and for this reason we always recommend a course of treatments to individuals who are looking to achieve maximum health and energy improvements. It is certainly evident that high concentrations of Vitamin B12 are an essential component of a healthy and active lifestyle.

For healthy individuals, the benefits of having vitamin B12 injections include an improvement in overall cerebral functioning as well as physical and psychological wellbeing. As a moderate appetite suppressant, one of the other potential benefits of B12 injections is easier weight loss. They can be used intermittently and are a popular rejuvenation therapy for exhaustion, ‘burn out’, migraines and – of course – post-party nausea!




Had you heard about the many health benefits of Vitamin B12 injections and now you want to know more?  VITB12SHOTS is a recognised training provider and supplier of Vitamin B12 across the UK and Spain and understand the effects of boosting this essential nutrient.


Vitamin B12 is somewhat of a wonder for your health and for various reasons many of us lack the quantities that our bodies need. This can include diet, age and lifestyle choices. One of the greatest health benefits of Vitamin B12 is that it regulates and even helps your metabolism. This can be hugely influential for long term weight control. Another massive benefit of taking in quantities of Vit B12 is where it aids in the formation of red blood cells and maintaining the central nervous system, also influential for the proper function and development of the brain.

Why Use Vitamin B12 for Health?

Vitamin B12 is said to help with a host of health concerns. For instance, research suggests that vitamin B12 may preserve your eyesight as you get older, fight heart disease, aid stroke recovery, and even rev up your defence against some forms of cancer.


Other purported health benefits of using Vit B12 include to enhance moods, increase energy, improve memory, stimulate the immune system, promote healthy sleep, and slow the ageing process.

Are You Lacking Vit B12?

Most people haven’t even heard of Vitamin B12 until it becomes relevant. There are a number of individuals that require regular boosters to improve their Health. Below we have listed some of the signs that you could lacking Vit B12.

Vegetarians and Vegans are at risk

Vitamin B12 occurs naturally in animal products. So if your diet largely consists of plant-based foods such as fruits, veggies, beans, and soy, you’re at risk for deficiency

Adults over 50 are also at risk

As you age, the stomach produces less acid, and stomach acid is key for B12 absorption, says Middleberg. About one in 31 adults over 50 are deficient, estimates the Centres for Disease Control and Prevention. “Older individuals also often have poorer appetites and food intakes, and they may be on medications (such as heartburn meds) that can further reduce stomach acid levels,” she says. In fact, some seniors actually lose the ability to absorb vitamin B12 from food at all, and must get it via supplements or, if the deficiency is severe, injections

Early symptoms include weakness and fatigue

B12 isn’t nicknamed the energy vitamin for nothing. Inadequate B12 intake makes a dent in red blood cell production, and some of the earliest signs of a deficiency include feeling dragged, confused, and weak. Problem is, says Middleberg, these clues are so vague, and not everyone experiences them the same way. And since they can be attributed to so many other possible triggers, most people don’t think to be tested. If these symptoms hit and stick around for weeks, it’s best to consult your doctor and rule out other causes, she says. Similar tip-offs include dizziness, impaired thinking, and confusion.

Heartburn drugs can cause it

Some prescription heartburn drugs suppress the production of stomach acid, which is needed to absorb vitamin B12. A 2013 study from the Journal of the American Medical Association backs this up. Researchers found that taking meds called proton pump inhibitors (like Prilosec and Nexium) for more than two years was linked to a 65% higher risk of vitamin B12 deficiency. And two years or more using H2 receptor blocker drugs (such as Pepcid and Zantac) is associated with a 25% boost in deficiency odds. If you take these regularly, consider a B12 shot.

Taking birth control pills sets you up for it

Women who have been on oral contraceptives for extended periods of time tend to have issues absorbing vitamin B12. Studies show that pills that are higher in oestrogen are more strongly associated with B12 and folate (folic acid, or vitamin B6) deficiencies, leading to the assumption that the oestrogen in the pill is the reason for this impaired absorption. If you’re on the pill, we recommend a B12 shot.

Heavy drinking increases your odds

More than a few drinks on average each day can cause gastritis, or irritation of the stomach lining, and this can lead to low stomach acid and reduced B12 absorption. Alcohol plays a role in deficiency in another way too. B12 is stored in the liver, and alcohol consumption can impair liver function and deplete B12 stores or make it harder for the liver to use it.

It can trigger a false positive on a Pap test

Vitamin B12 deficiency even affects the smear test you get at your regular screening for cervical cancer. Low B12 levels can change the way some cervical cells look, potentially triggering a false positive, according to the National Institutes of Health. Yet another reason to shore up your intake of the nutrient.

It’s linked to pernicious anaemia

There’s a specific type of anaemia that’s triggered by a B12 deficiency. Called pernicious (which means “dangerous,” because it was potentially life-threatening in the past) anaemia, it is a red blood cell deficiency that happens when the stomach doesn’t make enough of a protein called intrinsic factor, which helps the intestine absorb B12. Pernicious anaemia can be the result of an autoimmune issue, a problem with the stomach lining, or even a congenital condition passed down through families. Treatment usually involves B12 shots.

It’s linked to immune system issues

B12 plays an important role in white blood cell production, and white blood cells are essential for proper immune system functioning. Not only can a lack of B12 lower your immunity, some immune system disorders can increase your likelihood of becoming deficient. Grave’s disease, for example, an autoimmune condition of the thyroid causing hyperthyroidism, is a risk factor for developing pernicious anaemia, which in turn leads to B12 deficiency.

Digestive problems can cause it

People who deal with GI issues are at a higher risk of a B12 shortage because digestive problems can make absorbing the nutrient more difficult. Those with gut issues, such as colitis, Crohn’s diseaseinflammatory bowel disease, and leaky gut syndrome are at a higher risk. Celiac disease sufferers can also have problems with absorption. If you have any of these, talk to your doctor about B12 shots, since all the B12-rich food in the world won’t help your body shore up its reserves if it can’t be absorbed by the GI tract.




The energy vitamin!

Vitamin B12 is a powerhouse. It helps make DNA, nerve and blood cells, and is crucial for a healthy brain and immune system. Your metabolism wouldn’t run smoothly without it. But B12 isn’t like other vitamins. It’s only found in animal products like eggs, meat, shellfish, and dairy. Up to 15% of people don’t get enough B12, and they’re more likely to be vegetarians, have celiac disease or other digestion problems, or be an adult over 50. The signs of vitamin B12 deficiency include exhaustion, rapid heartbeat, brain fog, and other symptoms.


While bodybuilders are not likely deficient in B-12, making sure you meet your needs is essential for muscle building, exercise performance and overall health

Vitamin B-12 assists in metabolizing protein and fat. As a bodybuilder, you need the amino acids from the protein metabolism to repair and build your muscles and the fat as a source of energy. B-12 is also essential for the production of red blood cells, which are necessary for delivering oxygen to those muscles. This nutrient also supports healthy neurological function, which is needed for muscle control

Some people have a difficult time absorbing vitamin B-12 due to a decrease in stomach acidity, which is needed to help release the vitamin from the food. This may be the case if you take antacids, and it’s also a problem as you age.

Also, if you’re a vegan or vegetarian bodybuilder, there’s a risk that you may not be able to get enough if you’re not including fortified foods in your diet

Running, especially long distances, takes a significant toll on your body, requiring you to increase your nutrient intake. Running increases your heart rate, blood flow, breathing and need for excess calories. Essential nutrients are in greater demand, especially those influencing cardiovascular health, energy balance and protein metabolism. Vitamin B12 is required for all of these functions

If you are a runner who is beginning to feel lethargic and run-down or would like to enhance your performance, consider your intake of vitamin B12. Its primary role is to aid other nutrients. It assists in fat, cholesterol and protein metabolism by breaking them down into usable energy; ensures dietary folate becomes functional and is released into the body; maintains your neurological health and development; and helps form DNA, which is needed for constant cell formation. As a runner, your cell turnover and nutrient metabolism is greater than the average individual, so avoid becoming deficient.

Running, especially endurance and marathon training, uses more nutrients and places a lot of impact and stress on the body. Micronutrient deficiencies are more likely to occur and B-vitamin deficiencies are quite common, especially in female athletes and marathon runners. The B vitamins, including B12, are all necessary for energy maintenance. Their deficiency can impair performance, endurance and the conversion of food into energy. As mentioned, B12 is also required to prevent anaemia and enhance blood flow and heart function – all essential for optimum running. Thus, it is crucial for you runners to maintain a well-balanced diet if you want to see improvement in your performance.




Fertility and B12 Vitamins

Doctors have reported successful pregnancies in once-infertile women following therapy for B12 deficiency, yet often, sadly, this deficiency is overlooked even by infertility specialists until women have undergone months or even years of unsuccessful treatment. As a result, many couples spend thousands and suffer disappointment after disappointment, when treatment with B12 injections might have solved their problem.


How vitamin B12 affects fertility

Researchers don’t know exactly why a vitamin B12 deficiency makes it difficult to get pregnant and carry the baby to term. The deficiency could interfere with ovulation or normal cell division – and even affect how the fertilised ovum is implanted in the uterine lining.

Whatever the exact link is between vitamin B12 deficiency and female or male infertility, a course of B12 shots may improve the chances of getting pregnant naturally. 

Babies can get it too, in infants, vitamin B12 deficiency is serious—it can lead to symptoms such as anaemia, problems with movement, difficulty reaching developmental milestones, and failure to thrive, which may be fatal. Low B12 levels are rare in infants but it can happen if a baby is fed a strict diet free of any animal products or if a breastfeeding mom is a vegan who doesn’t take vitamin B12 supplements or shots (and breast milk is the only source of nutrition.) B12 supplementation can reverse the course, and taking prenatal vitamins along with a B12 Shot in pregnancy can help prevent it.

Don’t let this alarm you – it’s easy to get enough vitamin B12 if you eat a healthy, balanced diet with lots of lean red meats and eggs. Just pay attention to the B12 levels in your food; but if you’re not sure if your getting enough, consider a vitamin B12 shot as you cannot overdose on B12, your body will simply use what it needs and store some for later.

Male Fertility & B12


Since the 1970s scientists have been investigating the effects of B12 supplementation on sperm count. It’s believed that deficiencies in this vitamin lead to genetic damage of the sperm cells, causing infertility. Modern diets are typically saturated with highly processed foods and consequently B12 deficiencies are not uncommon.

In a study by Sanler and Faragher, vitamin B12 injections have been shown to increase fertility in men with low sperm counts. In this study, 27% of men with abnormal sperm counts (below 20 million per millilitre) showed a significant increase in sperm count (more than 100 million per millilitre) after a daily dose of 1,000 mcg of vitamin B12.

In a Japanese study, researchers administered 1,500 mcg per day of methyl cobalamin orally for between two and thirteen months. Improved sperm counts were observed in 60% of men receiving the supplement. The longer the period of supplementation, the more stable the sperm counts.

Most studies show that men with B12 deficiencies and low sperm counts can significantly benefit from large-dose supplementation. Men not deficient in B12 have also been reported to benefit from additional B12. One theory is that with higher levels of B12 the body is able to increase metabolism and provide more resources to manufacture sperm. Another theory is that increased red blood cell production may improve oxygenation and overall reproductive health. Although more research is necessary, mega-dosing vitamin B12 is considered relatively safe.

Vitamin B12 and Erectile Dysfunction

There are many physical factors that contribute to erectile dysfunction. Insufficient supply of B12 can damage the nerves within the penis. Left untreated, the damage will prevent the development and maintenance of an erection. This can lead to fertility problems by reducing the ability to sustain intercourse and subsequent ejaculation. It’s important if men are having erectile dysfunction symptoms that they seek medical attention and test vitamin B12 levels. Not only will this vitamin help to protect nerves within the penis, it will also support healthy circulation to promote strong erections.




It’s estimate that up to 20% of people aged 50 and over may be low in vitamin B12, with this deficiency becoming more common as people get older. It’s common, serious, and worst of all, commonly overlooked until it causes significant health problems.

But if you know the symptoms and risk factors, you can help your parents get a vitamin B12 deficiency detected. Treatment is safe and effective, as long as you catch the problem before permanent damage occurs. Here’s what to know.

How Vitamin B12 Deficiency Harms a Senior’s Health

In the body, vitamin B12 — also known as cobalamin — is especially vital to making red blood cells, and maintaining proper function of nerve cells. When vitamin B12 levels are low, a person can develop health problems related to red blood cells and nerve cells not working well.

The most common problems related to low vitamin B12 levels include:

·         Anemia. This means low red blood cell count. Red blood cells carry oxygen in the blood, so anaemia can cause fatigue or shortness of breath. The breakdown of faulty red blood cells can also cause jaundice.

·         Neuropathy. This means nerves in the body not working well. This can cause a variety of symptoms, including tingling, numbness, burning, poor balance and walking difficulties.

·         Cognitive impairment. This means that nerve cells in the brain are not working well. This can cause memory problems, irritability, and even dementia. 


You may have heard that vitamin B12 deficiency can cause pernicious anemia. But in fact, the term “pernicious anaemia” means a vitamin B12 deficiency that’s caused by the loss of a body’s ability to make “intrinsic factor.” The body needs intrinsic factor to absorb vitamin B12; without it, vitamin B12 levels eventually drop. This often causes anaemia, but sometimes symptoms of nerve and brain problems occur first.

Why Low Vitamin B12 Levels Are Common in Older Adults

As people get older, their ability to absorb vitamin B12 tends to decrease. This is because seniors often develop problems with the acids and stomach enzymes needed to process the vitamin.

Common risk factors for low vitamin B12 levels in older adults include:

·         Low levels of stomach acid, which can be due to weakening of the stomach lining, or to medications that reduce stomach acid

·         Medications such as metformin (used for diabetes), which interferes with vitamin B12 absorption

·         Alcoholism, which irritates the stomach and sometimes is linked to a poor diet

·         Surgeries that remove parts (or all) of the stomach or small intestine

·         Any problem that causes poor absorption in the stomach or small intestine, such as Crohn’s disease

Why Vitamin B12 Deficiency is Often Missed in Seniors

Vitamin B12 deficiency is often missed because the symptoms: fatigue, anaemia, neuropathy, memory problems, or walking difficulties, are quite commonly associated with getting older and can easily be caused by something else.

Also, vitamin B12 deficiency tends to come on very slowly, so people often go through a long period of being mildly deficient. During this time, a senior might have barely noticeable symptoms, or the symptoms might be attributed to another chronic health condition.

Still, a mild deficiency will almost always get worse over time. And even when a senior has many other causes for fatigue or problems with mobility, it’s good to fix whatever aggravating factors — such as a vitamin deficiency — can be fixed.

Unlike many problems that affect seniors, vitamin B12 deficiency is quite treatable. 

Are There Other Benefits To Taking Vitamin B12 Supplements?

Since we know vitamin B12 is necessary for proper function of red blood cells and brain cells, you might be wondering if your parent should take higher doses of vitamin B12 as part of a healthy aging approach.

It certainly won’t hurt, since vitamin B12 doesn’t cause problems at higher blood levels the way some vitamins do, and the good thing about vitamin B12 treatment is that it’s basically impossible to overdose. Unlike some other vitamins, vitamin B12 doesn’t cause toxicity when levels are high.
