Before you get any type of injection, though, it’s good to have a basic understanding of how you can expect it to affect you. Here are the three questions a client typically asks before getting a B12 vitamin injection. Some people get injections because they have a B12 deficiency.

• The symptoms of a low level of this vitamin in your body can range from something as mild as minor fatigue or a headache to more disconcerting factors such as memory loss or significant muscle stiffness and pain.
• If you are starting from a low level of deficiency, you may need several injections over the course of a week to start seeing any real improvement.

If more severe symptoms are what prompted you to get the treatment, however, it may take more time to make a noticeable difference. In this case, your body must repair the damage that is causing your dizziness, tingling in your extremities or balance control issues.

Multiple doses of B12 will likely be necessary to facilitate the recovery. Only then will your symptoms subside. When used as a maintenance or preventative measure, however, you may notice a difference as soon as the day after any of your, If you notice a significant increase in your overall well-being, consider making the injections a regular habit.

If you enjoy the effects of the injection, there’s no reason not to continue to get them for the rest of your life. B12 is a water-soluble vitamin and has a low risk of toxicity. You are unlikely to overdose on it even if you get frequent treatments. Every person has different needs, though, so it’s important to pay attention to your body when deciding how often to get injections.

• You may get several shots the first week or two after you start and then decrease the frequency to once a month.
• If the benefits don’t taper off at all, you may be able to increase the length of time between injections.
• Try changing the interval to six weeks and then increase it to two months between shots.

There are a few things that can make your B12 injection less effective or shorten the length of time you can enjoy the benefits. People with certain liver disorders may need the shot more often. If you do not eat a diet rich in B12 vitamins or drink alcohol regularly, you may need to supplement with an injection sooner rather than later.

1. To prolong the effects of the extra boost, be sure to eat a well-balanced diet that includes fish, beef, liver, eggs, dairy and foods fortified with B vitamins, and limit your consumption of alcohol.
2. In most cases, an injection of vitamin B12 is going to make you feel fantastic.
3. Right after you receive the shot, however, you may see some slight skin irritation at the injection site.

Redness and swelling may occur, and the area may be painful for a few hours. Give yourself the time to avoid vigorous activity right after the treatment to minimize these side effects. You may also experience some other reactions immediately after the injection is administered.

1. The sudden increase in B12 can cause nausea, dizziness and headaches when first injected into the muscle.
2. The human body is usually quick to adjust, though, so these symptoms should fade soon afterward.
3. In rare cases, B12 can affect your potassium levels, causing muscle cramps or spasms.
4. Other signs that you have a potassium deficiency are an irregular heartbeat and extreme fatigue.

If you experience any of these symptoms or develop a persistent, low-grade fever, call your doctor. Taking care of your body is already a priority for you, but can give you an extra boost. Contact Treadwell for more information or to schedule your appointment today.

However, many patients find that regular injections are the best way to maintain results. For patients who are naturally B12 deficient, more frequent injections about once a month may be ideal.

For other patients, an injection every three to four months may suffice. We will help you determine the best frequency to get the results you want.

Can you sleep after a B12 shot?

Our bodies require a daily intake of essential vitamins and minerals in order to properly function. If one of these vitamins is deficient, it can result in serious health problems. Most of our B12 comes from meat in our diet. Those who are unable to absorb an adequate amount of B12 due to dietary restrictions or health problems may need to get a natural supplement through a B12 shot.

The shot is a quick way to get your B12 levels back to where they should be. An injection of B12 can bring on immediate health benefits. If you are constantly lethargic even after a full night of sleep, you may have need B12 shots. This vitamin is required in the production of red blood cells. Red blood cells transport oxygen around your body, providing the fuel your cells need to produce energy.

A loss of red blood cell production will create symptoms of low energy and inability to concentrate. A deficiency of the B12 vitamin causes anemia. An anemic individual can not efficiently convert fats and proteins into energy. This leads to the frustrating situation of difficulty losing weight despite regular exercise and a good diet.

• A lack of B12 interferes with your body’s ability to produce white blood cells.
• These cells are essential in fighting off infections and keeping your immune system in good working order.
• If you find yourself getting sick more often than usual or having allergies where you previously had none, you may need a B12 shot.

Tryptophan is the amino acid found in foods like turkey that makes you drowsy. Our body manufactures tryptophan naturally, and it’s a big part of what helps you fall asleep at night.

Do B12 shots affect mood?

2. Helps Against Anxiety and Depression – All the B vitamins, and especially B12, are crucial for your brain function. A deficiency can lead to depression and anxiety. B12 shots can be a powerful tool to help manage your mood and mental health. Low levels of B12 can affect the synthesizing process of mood-regulating neurotransmitters like serotonin and dopamine.

Why do I feel good after taking B12?

5. May improve mood and symptoms of depression – Vitamin B12 may improve your mood. The effect of vitamin B12 on mood is not yet fully understood. However, this vitamin plays a vital role in synthesizing and metabolizing serotonin, a chemical responsible for regulating mood ( 20 ).

1. Therefore, vitamin B12 deficiency may lead to decreased serotonin production, which can cause a depressed mood.
2. One older study in people with depression and vitamin B12 levels on the low side of normal found that those who received both antidepressants and vitamin B12 were more likely to show improved depressive symptoms, compared to those treated with antidepressants alone ( 21 ).

In a large review, researchers discovered that vitamin B12 deficiency was associated with a higher risk of depression, but only in older females ( 22 ) Though vitamin B12 supplements may help improve mood and depression in people with a deficiency, research does not currently suggest that they have the same effect in those with normal B12 levels ( 23 ).

Does vitamin B12 affect mood?

Review – Our review focuses on the effects of Vitamin B12 supplementation at the onset or during the prognosis of depression. A total of 35 studies and articles were reviewed for this review, We used PubMed and Google Scholar as our main databases to identify, screen, and choose the relevant articles.

We chose the studies that were relevant to the topic and were published in English. We did not include gray literature or unpublished studies. Vitamin B12 and hyperhomocysteinemia Micronutrients are known to affect the normal structure and functions of the brain. For this paper, we will be focusing on one specific micronutrient – Vitamin B12.

Cyanocobalamin, also known as Vitamin B12, is one of the most important water-soluble vitamins. The primary functions of Vitamin B12 are appropriate red blood cell formation, neurological functioning, and DNA synthesis, Deficiency of Vitamin B12 can result in hematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss,

• It is also known to worsen depression by excitotoxic reactions caused by the accumulation of homocysteine,
• Vitamin B12 deficiency is reportedly known to cause mental disturbances in numerous individuals.
• However, there is little evidence to show the correlation between psychosis and Vitamin B12.
• Cobalamin is one of the essential elements for monoamine neurotransmitter synthesis in the brain.

A study published in 2011 in the Academy of Psychosomatic Medicine included supplementation of Vitamin B12 and folate, which resulted in improved cognitive functioning among patients participating in the study. A borderline Vitamin B12 level of 75-95 pg/mL, as well as up to a normal level of 307 pg/mL, is known to cause neuropsychiatric symptoms in patients, and such symptoms may start manifesting even with such borderline deficiencies or low normal levels of Vitamin B12.

• The study does dispute if the effects were of the Vitamin B12 supplementation or anti-depressant medications; however, it concludes that supplementation did increase the overall response to the anti-depressants,
• Hyperhomocysteinemia Higher homocysteine levels are associated with a phenomenon called “methionine loading.” A deficiency of Vitamin B12 along with B6 and folate usually prevents the conversion of homocysteine to methionine, increasing the levels of homocysteine.

Hyperhomocysteinemia can also occur in patients with renal disorders or genetic alterations of methyl-tetrahydro-folate reductase or cystathionine beta-synthetase, which are required for the metabolism of homocysteine, Higher levels of homocysteine affect the DNA formation and overall turnover of red blood cells (RBCs), causing the development of megaloblastic or pernicious anemia, ultimately affecting the cognitive ability and mood of the patient, Neurochemical Pathways Affected by Vitamin B12 Levels Vitamin B12 is interdependent with other micronutrients, mainly Vitamin B6 and folate. This interdependence affects multiple neuronal pathways that are not directly controlled by Vitamin B12. Neurotransmitters are required to conduct the signals from one neuron to another, with the help of pre- and post-synaptic junctions.

The malfunctioning of any of these pathways can lead to depression, Lower Vitamin B12 levels are also known to increase the risk of cognitive decline, Alzheimer’s disease, and dementia. According to Vogiatzoglou et al., higher Vitamin B12 levels have proven to protect patients against brain atrophy,

Pathophysiology of depression Over a decade ago, depression was commonly seen in adult and elderly patients but had become far more common among the younger population. According to the Journal of Psychological Medicine, the rates of depression have increased drastically among children as young as 12 years and older.

Depression, once diagnosed, is clinically treated with anti-depressants and cognitive behavioral therapy (CBT). In patients where the anti-depressant regimen is not eliciting a response, an additional drug from a different pharmaceutical group has proved to have a significant effect, However, long-term and extensive pharmacotherapy are almost always associated with the extent of undesirable effects on the patient like the risk of major adverse cardiovascular events, decline in cognitive functioning over time, behavioral changes including but not limited to sexual problems, and feeling of “emotional numbness.” The B vitamins are crucial particulates of the 1-carbon metabolism wherein 5-methyltetrahydrofolate and methylcobalamin help convert homocysteine to methionine, which in turn forms S-adenosylmethionine (SAM), which is the essential methyl donor required for the production of monoamine neurotransmitters, phospholipids, and nucleotides,

A study performed in 2010 by Skarupski et al. included a sample US population of 35,053 older adults, and the results of this study stated that higher intakes of Vitamin B12 and B6 were associated with a lower risk of developing depressive symptoms by an average of 7.2 years,

According to Hutto, cobalamin and folate are components of the synthesis of monoamine neurotransmitters, which may lead to psychotic behavior by a rise in BH4 (tetrahydrobiopterin) production, Moorthy et al. published an article in the Journal of Nutrition in 2010, which discussed the C677T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene in various ethnic groups.

The study showed lesser scores on the Mini-Mental Status Exam (MMSE) and higher depression scores among patients with lower plasma levels of Vitamin B12, Daily supplementation of oral Vitamin B12 (100 mcg) and folic acid (400 mcg) has been shown to increase cognitive function in a randomized controlled trial performed by Walker et al.

1. In 2012, They proposed two theories by which this could occur: reduced homocysteine levels and lowered vascular and metabolic risk factors occurring due to supplementation with Vitamin B12 and folic acid,
2. Another study performed in 2012, specifically among the Iranian population with major depressive disorders, also indicated lower plasma concentrations of Vitamin B12 among the Tabrizian patients who had depressive symptoms,

Melancholic depressive symptoms were more relatively associated with lower plasma Vitamin B12 levels. One such study reviewed concluded that Vitamin B12 deficiency played an important role in the pathogenesis of depressive symptoms, A randomized controlled trial performed in 2013 among the Pakistani population attempted to identify the coexistence of depression and Vitamin B12 deficiency.

1. This study reported that 22% of the sample depressed population had associated low Vitamin B12 levels to constitute a deficiency, 36% had low normal Vitamin B12 levels, and 42% of the sample population had normal serum B12 levels,
2. Vitamin B12, in combination with folic acid, is known to reduce the levels of homocysteine, thereby reducing the toxic effects and thus improving the effect of anti-depressants by increasing the effectiveness of anti-depressants S-adenosylmethionine (SAMe),

A study performed among the Indian population in 2017 demonstrated that Vitamin B12-deficient individuals, mostly vegetarians, were more prone to developing neurological problems, Figure ​ 3 illustrates the effects of Vitamin B12 deficiency on depression. Pathophysiology of Depression The total cyanocobalamin and methylcobalamin levels in patients with autism and schizophrenia were reported to be lower as compared to the age-matched control subjects. Although the association with the levels and depression was not performed, the study analyzed brain samples,

1. It concluded Vitamin B12-dependent methylation reactions in the brain played a crucial role in the presentation of neurological symptoms and disorders,
2. A cross-sectional study was performed in 2018 to understand the association between vitamins and depression to gather data more based explicitly on sex-specific criteria; evidently, females were identified to be more at risk as compared to men and had coinciding lower serum Vitamin B12 levels,

Low normal serum Vitamin B12 is also posing a risk to pregnant women and makes them more prone to develop depressive symptoms. According to a secondary analysis of the National Health and Nutrition Examination Survey and a reported Patient Health Questionnaire-9 (PHQ-9) score of 10 or more among the subjects, pregnant women were reported to be 3.82 times more predisposed to developing depression,

• One-carbon metabolism has been extensively linked with psychiatric disorders among numerous studies.
• One such recent study published in 2020 comprised of 89 patients, mainly children and adolescents, and included a patient group that was already diagnosed with depression and a control group.
• They were subsequently tested for serum levels of Vitamin B12, homocysteine, and Vitamin D.

The study utilized correlation analysis and showed a negative relationship between the severity of depressive symptoms and Vitamin B12, and associated hyperhomocysteinemia, concluding that low normal levels or deficiency of Vitamin B12 can become a significant contributing factor toward depression,

1. Case-control studies performed have yielded similar results; however, the sample population has been limited, which necessitates studies comprising larger population groups.
2. Patients diagnosed with depression are highly likely to be non-compliant, thus suggesting better ways of managing and overcoming the non-compliant behavior, which also goes hand in hand with improper dietary intake of essential nutrients.

Khosravi et al. performed a case-control study to identify the correlation between increased and decreased intake of Vitamin B12 and folate with depression and its severity. An inversely proportional relationship was established between Vitamin B12 and folate levels and depression,

Is weight gain a side effect of B12 injections?

Our team thoroughly researches and evaluates the recommendations we make on our site. To establish that the product manufacturers addressed safety and efficacy standards, we:

Evaluate ingredients and composition: Do they have the potential to cause harm? Fact-check all health claims: Do they align with the current body of scientific evidence? Assess the brand: Does it operate with integrity and adhere to industry best practices?

We do the research so you can find trusted products for your health and wellness. Vitamin B12, also known as cobalamin, is a water-soluble vitamin that’s involved in various essential bodily processes. For instance, your body uses it to make DNA and create new red blood cells, as well as produce energy.

1. It may even affect your mood and memory and is instrumental in helping your brain and nervous system function properly ( 1, 2, 3 ).
2. Therefore, a deficiency in this nutrient can have debilitating health effects.
3. What’s more, some people have recently suggested that unwanted weight gain be added to the list of possible side effects.

This article reviews the latest scientific evidence to determine whether a vitamin B12 deficiency may result in weight gain. To absorb vitamin B12 effectively, your body requires an intact stomach and gut, a well-functioning pancreas, and sufficiently high levels of intrinsic factor, a protein that binds to vitamin B12 in the stomach ( 1 ).

Adult women require 2.4 mcg of vitamin B12 per day, This requirement increases to 2.8 mcg per day during pregnancy and breastfeeding. Adult men can meet their needs by consuming 2.6 mcg of vitamin B12 per day ( 1 ). Extra vitamin B12 can be stored in the liver, and only small amounts are lost through your urine, sweat, or stools each day.

Because of this and the small daily requirements, it can take a year or longer of insufficient vitamin B12 intake to develop an overt deficiency ( 1 ). However, once present, it can have debilitating consequences. Symptoms of vitamin B12 deficiency include ( 1 ):

chronic fatigueshortness of breathheart palpitationstingling or numbness in the extremitiespoor balanceloss of concentrationpoor memorydisorientationmood changesincontinenceinsomnia

People most at risk of developing a deficiency include older adults, as well as those who smoke, abuse alcohol, or follow a vegetarian or vegan diet, Gut surgery, pancreatic insufficiency, small intestinal bacterial overgrowth (SIBO), parasite infections, and certain autoimmune disorders are considered additional risk factors.

Moreover, certain medications, including metformin, proton pump inhibitors, and antacids may also reduce your body’s ability to absorb vitamin B12 from your diet ( 1, 4 ). summary Vitamin B12 deficiency can manifest itself through a variety of symptoms. People most at risk of deficiency include older adults, vegans, and those with specific medical conditions or taking certain medications.

Despite the numerous processes in which vitamin B12 is involved, there’s little evidence to suggest that it has any influence on weight gain or loss. Most of the evidence giving rise to this claim comes from a few observational studies. For instance, one study notes that people with excess weight or obesity appear to have lower vitamin B12 levels than people who have a body mass index (BMI) in the “normal” range ( 5 ).

Additional research has observed that people who voluntarily took vitamin B12 supplements gained between 2.5–17 fewer pounds (1.2–7.7 kg) over 10 years than those who did not supplement with this vitamin ( 6 ). Still, such observational studies cannot confirm whether low vitamin B12 levels are what caused the weight gain, nor whether they’re what protected against low levels.

On the other hand, a vitamin B12 deficiency appears to cause a loss of appetite in some people, leading to weight loss rather than weight gain ( 7, 8 ). That said, the current evidence is too weak to suggest that a vitamin B12 deficiency has any strong or specific impact on weight — be it weight gain or loss.

Meat and chicken: especially organ meat and red meat like beef Fish and seafood: especially clams, sardines, tuna, trout, and salmon Dairy: including milk, cheese, and yogurt Eggs: especially egg yolk Fortified foods: breakfast cereal, nutritional yeast, as well as some mock meats or plant milks

Supplements, which are widely available in stores and online, are another way to meet your daily requirements. They’re especially handy for people with low levels of intrinsic factor, a protein that helps your body absorb vitamin B12 more easily ( 9 ).

Additionally, they can help those who have difficulty consuming sufficient amounts of the foods above meet their daily vitamin B12 needs. This may include vegetarians or vegans who don’t plan their diet carefully ( 10, 11 ). summary Vitamin B12 can be found in animal products, as well as foods fortified with it.

Supplements are a practical way for some people to ensure they meet their daily vitamin B12 requirements. Vitamin B12 is a water-soluble vitamin that your body uses for a variety of processes, including producing energy and maintaining a healthy brain and nervous system.

How long does it take to correct B12 deficiency?

If you have a vitamin B12 deficiency, it can take up to six to 12 months to fully recover. Vitamin B12 deficiency is common, especially among vegetarians and older adults. Also known as cobalamin, vitamin B12 is a water-soluble vitamin found in meat, fish, and dairy.

1. Vitamin B12 is essential for brain and nerve function.
2. A vitamin B12 deficiency can cause headaches, fatigue, muscle weakness, and depression.
3. Low levels of vitamin B12 can be due to not getting enough vitamin B12 in your diet or the body being unable to absorb the vitamin due to another medical condition.

Diagnosing vitamin B12 deficiency can be tricky because the symptoms are similar to other health conditions. This article looks at the symptoms, causes, and diagnosis of vitamin B12 deficiency. It also discusses treatment for vitamin B12 deficiency. Verywell / Luyi Wang

How do I know if B12 injections are working?

Having your hydroxocobalamin injection When you first start having your hydroxocobalamin treatment, you’ll usually have an injection a few times a week. Your dose may go up or down, depending on your response to the treatment and the vitamin B12 levels in your blood.

How much B12 do you need to feel energy?

B12 for improved energy – Though vitamin B12 is commonly taken to increase energy levels, evidence showing that B12 supplements improve energy levels in people without a deficiency is lacking. However, B12 supplements may help increase energy levels and reduce fatigue those who are deficient in this nutrient ( 20 ).

How long does it take for B12 to hit your system?

Treatment – Treatment for this condition involves replacing the missing vitamin B 12, People who cannot absorb B 12 need regular injections. When injections first are administered, a patient with severe symptoms may receive five to seven during the first week to restore the body’s reserves of this nutrient.

A response usually is seen within 48 to 72 hours, with brisk production of new red blood cells. Once B 12 reserves reach normal levels, injections of vitamin B 12 will be needed every one to three months to prevent symptoms from returning. People who cannot absorb vitamin B 12 should continue to eat a well-balanced diet that provides other nutrients ( folic acid, iron and vitamin C) necessary to produce healthy blood cells.

Sometimes people can take high doses of oral B 12 to provide replacement instead of undergoing injections, but a physician should closely supervise this. In people whose vitamin B 12 deficiency is related to overgrowth of intestinal bacteria, treatment with oral antibiotics, such as tetracycline (sold under several brand names), may stop bacterial overgrowth and allow the absorption of vitamin B 12 to return to normal.

Can you sleep after a B12 shot?

Our bodies require a daily intake of essential vitamins and minerals in order to properly function. If one of these vitamins is deficient, it can result in serious health problems. Most of our B12 comes from meat in our diet. Those who are unable to absorb an adequate amount of B12 due to dietary restrictions or health problems may need to get a natural supplement through a B12 shot.

4. This vitamin is required in the production of red blood cells.
5. Red blood cells transport oxygen around your body, providing the fuel your cells need to produce energy.

A loss of red blood cell production will create symptoms of low energy and inability to concentrate. A deficiency of the B12 vitamin causes anemia. An anemic individual can not efficiently convert fats and proteins into energy. This leads to the frustrating situation of difficulty losing weight despite regular exercise and a good diet.

A lack of B12 interferes with your body’s ability to produce white blood cells. These cells are essential in fighting off infections and keeping your immune system in good working order. If you find yourself getting sick more often than usual or having allergies where you previously had none, you may need a B12 shot.

Tryptophan is the amino acid found in foods like turkey that makes you drowsy. Our body manufactures tryptophan naturally, and it’s a big part of what helps you fall asleep at night. Vitamin B12 is a major factor in the tryptophan production process. B12 injections can help you go from restless nights to getting a good night sleep.

Hair loss is so common in men, that a B12 deficiency as the cause of it is often missed. Because cells are not being metabolized efficiently, it is difficult for hair growth to occur normally.
