Vitamin B12 Rich Foods

Vitamin B12 shots and pills are popular among people looking for a quick weight-loss solution. Some even believe that increasing your vitamin B12 levels would help you reduce fatigue, enhance energy, and speed up your metabolism. However, investigations on the effects of this vitamin on weight loss have shown contradictory results.

Vitamin B12 is a water-soluble vitamin that is required for brain function, heart health, the creation of red blood cells, and the formation of DNA. According to certain studies, vitamin B12 levels in the blood are linked to a lower risk of obesity in both children and adults. Furthermore, animal studies indicate that it may have an effect on body fat and metabolism.

Vitamin B12 insufficiency is alleviated by increasing intake through food or supplements. However, if you obtain enough vitamins in your diet, increasing your vitamin B12 intake may not help you lose weight. There have been no studies that link an overabundance of vitamin B12 to weight loss.

What exactly is Vitamin B Complex?

The vitamin B complex contains the following B vitamins:

  • Thiamine is another name for B1.
  • B2 is also known as riboflavin B3, niacin B5, pantothenic acid B6, pyridoxine B7, and biotin B9 is also known as folic acid
  • B12 is also known as cobalamin.
  • Each of these vital vitamins contributes to the healthy functioning of your body.

B vitamins are necessary for maintaining good health and happiness. B vitamins have an immediate impact on our energy levels, cognitive function, and cell metabolism. As a result, they are the foundation of a healthy body. Furthermore, they help with many of our bodies’ critical activities.

What Is the Function of Vitamin B12?

Vitamin B12 is a necessary B vitamin. It is required to keep nerve tissue, brain function, and red blood cells healthy. Cobalamin is another name for vitamin B12. Deficiency can develop when this vitamin’s levels are too low. Furthermore, a lack of vitamin B12 can result in long-term neurological disorders.

Vitamin B12 is a water-soluble vitamin, like the other B vitamins. It is water soluble and can travel through the bloodstream. As a result, vitamin B12 reserves remain in the human body for four years. The urine then excretes any extra vitamin B12. Vitamin B12 is the most abundant and physically complicated vitamin we consume. It exists naturally in animal products and can only be produced industrially through bacterial fermentation synthesis.

Vitamin B12 Rich Food Sources

Vitamin B12 is found in a variety of animal products, including fish, meat, eggs, and dairy. Plant-based sources are in short supply. Foods high in vitamin B12 include:

  • Milk\sCheese\sLamb
  • Haddock and tuna are two examples of fish.
  • Several yeast products that are healthy
  • Eggs
  • Yogurt Pork Ham Poultry Beef Pork Pork Pork Pork Pork Pork Pork Pork Pork Pork
  • Soy milk and breakfast cereals come in a variety of flavours.

Vitamin B12 supplements come in the form of pills, capsules, liquids, and tablets. It’s also commonly found in multivitamins. Those who do not consume vitamin B12 rich animal products on a daily basis may want to consider adding fortified foods to their diet. To achieve their dietary requirements, they can take a supplement.

Vitamin B12 Rich Food Sources

Shiitake Mushrooms

Shiitake mushroom rich in vitamin b12

This vitamin is rich in Shiitake Mushrooms. However, to meet your vitamin B12 requirements, you must consume 50-60 grammes of dry mushrooms every day.

The Advantages of Including Vitamin B12 in Your Diet

Vitamin B12 is required for proper brain and neurological function. It also contributes in the formation and regulation of DNA. It is also important in the formation of red blood cells. Furthermore, vitamin B12 is required for the metabolism of all cells. It assists in the synthesis of fatty acids and the production of energy.

Vitamin B12, for example, permits energy to be released by assisting the human body in absorbing folic acid.

Millions of red blood cells are produced by the human body every minute. These cells will not be able to grow if vitamin B12 is not present. Red blood cell production declines when vitamin B12 levels are too low. Anaemia can occur if the red blood cell count is too low.

Contributes to the production of red blood cells and the prevention of anaemia:

Vitamin B12 is required for the production of red blood cells in the body. A lack of vitamin B12 affects the development of red blood cells and stops them from developing properly.

Furthermore, a lack of vitamin B12 causes red blood cells to become larger and oval. Healthy red blood cells, on the other hand, are small and spherical.

When red blood cells cannot migrate from the bone marrow, the condition is known as megaloblastic anaemia. They cannot circulate at a normal rate because to their larger and irregular nature.

As a result, your body does not produce enough red blood cells to transport oxygen to your vital organs. As a result, you become anaemic. This may cause fatigue and weakness.

Possibility of preventing serious congenital disabilities:

For a healthy pregnancy, vitamin B12 levels must be adequate. According to research, a foetus’s brain and nervous system require adequate vitamin B12 from the mother in order to develop.

As a result, a lack of vitamin B12 during the first trimester of pregnancy may increase the risk of birth defects. For example, neural tube defects. Furthermore, a mother’s deficiency of vitamin B12 may result in a premature birth or miscarriage.

According to studies, women with vitamin B12 levels below 250 mg/dL are three times more likely to have a child with birth defects.

Women who have a vitamin B12 deficiency with levels below 150 mg/dL, on the other hand, are at five times higher risk.

May aid in the prevention of osteoporosis and the maintenance of bone health:

A lack of vitamin B12 might weaken your bones. As a result, maintaining your levels is critical. A study of over 2,500 adults discovered that persons who are deficient in vitamin B12 have lower than average bone mineral density.[1]

Reduced mineral density in the bones can lead to brittleness and fragility over time. As a result, the risk of osteoporosis rises. Furthermore, low vitamin B12 levels have been linked to poor bone health and osteoporosis, especially in women, according to study.

Vitamin B12 lowers the risk of macular degeneration:

Macular degeneration is a type of vision loss that primarily affects the central vision. A lack of vitamin B12 may contribute to age-related macular degeneration.

According to studies, supplementing with vitamin B12, an amino acid found in plasma, may lower homocysteine levels. Furthermore, homocysteine levels beyond a particular threshold can raise the risk.

Vitamin B12, folic acid, and vitamin B6 may reduce this risk, according to a study of 5,000 women aged 40 and up.

Unlike the placebo group, which took these supplements for seven years. They had a lower rate of macular degeneration. Furthermore, it lowered the likelihood of any form of the condition by 34%. Furthermore, it lowered the likelihood of acquiring more severe diseases by 41%.

More research is needed, however, to fully appreciate vitamin B12’s importance in maintaining eye health and avoiding macular degeneration.

Supplements rich in B12 are

Adiimin – Used for weight loss

Sonavel – Used for tinnitus and hearing loss

Claritox Pro – Used for dizziness and vertigo

Nervexol – Natural Pain Relief supplement

Tinnitus 911 – As the name suggests.

Nervogen Pro – For Nerves

Flexotone – For joint and back pain

May aid in the treatment of depression symptoms and mood:

Vitamin B12 may assist you in feeling healthier. The effect of vitamin B12 on mood is still unknown. This vitamin, on the other hand, is required for the creation and metabolism of serotonin, a neurotransmitter that affects mood.

As a result, a lack of vitamin B12 can limit serotonin production. Depression may ensue as a result. Vitamin B12 pills can help those who are deficient in vitamins feel better.

Only antidepressants, on the other hand, show a slight improvement, according to one study. Another study discovered a relationship between vitamin B12 deficiency and a twofold increase in the risk of severe depression.[2]

Furthermore, high vitamin B12 levels are linked to better treatment outcomes. Recovery appears to be more likely. As a result, vitamin B12 pills may help people with deficiencies improve their mood and sorrow. However, there is no evidence that they have an effect on those who have normal vitamin B12 levels.

People who suffer from depression and low vitamin B12 levels take antidepressants as well as vitamin B12 tablets. As a result, they are more likely to have fewer depressive symptoms.

Vitamin B12 may be beneficial to your brain by avoiding cell degeneration:

Memory loss can occur as a result of vitamin B12 deficiency, especially in the elderly. Furthermore, the vitamin may aid in the prevention of brain atrophy, which is the loss of neurons in the brain. And it can lead to memory loss or the start of dementia at a young age.

According to one study, combining this vitamin with omega-3 fatty acid supplements slowed mental decline in persons with early-stage dementia. Another study, however, revealed that even low vitamin B12 levels may impair memory performance.

As a result, even if you don’t have a clinically recognised memory deficiency, taking this vitamin may assist. More research is needed, however, to draw firm conclusions about the effect of vitamin B12 supplements on memory and cognitive function.

It may give you an energy boost:

According to certain promotional materials, vitamin B12 supplements are the go-to option for a surge of energy. However, they do not always provide energy. All B vitamins are essential for your body’s energy production.

Exhaustion or a lack of energy, on the other hand, is one of the most common early signs of vitamin B12 deficiency.

Lowering homocysteine levels may benefit heart health:

Homocysteine, a common amino acid in the blood, has been linked to an increased risk of heart disease.

When you don’t get enough vitamin B12, your homocysteine levels rise. In research, vitamin B12 was proven to help reduce homocysteine levels. As a result, your risk of heart disease may be reduced.

There is, however, no coherent scientific data to back up the assertion. As a result, more research is needed to understand the relationship between vitamin B12 and heart health.

Helps to maintain healthy hair, skin, and nails:

Because of vitamin B12’s involvement in cell synthesis, enough quantities are required to ensure healthy hair, skin, and nails.

In truth, low vitamin B12 levels can induce a variety of dermatological complaints. Hyperpigmentation, nail discoloration, hair alterations, vitiligo, and angular stomatitis are all symptoms of vitiligo.

Supplementing with vitamin B12 has been shown to aid people who are deficient in it. This alleviates their dermatologic issues. However, if you’re well-nourished and not deficient in this vitamin, taking a supplement is unlikely to improve your skin, nail strength, or hair health.

Vitamin B12 Deficiency Symptoms

  • Over time, it can cause irreversible and serious damage, particularly to the neurological system and brain.
  • Slightly lower-than-normal vitamin B12 levels cause symptoms such as depression, confusion, memory problems, and fatigue. However, these symptoms are insufficient to diagnose B12 deficiency.
  • Constipation, a loss of appetite, and weight loss are all symptoms of vitamin B12 deficiency.
  • Neurological abnormalities, such as limb numbness and tingling, may arise.
  • Furthermore, some people may struggle to maintain their equilibrium.
  • Infants that are vitamin B12 deficient may exhibit unusual movements such as facial tremors and reflex abnormalities, feeding difficulties, irritability, and developmental problems.
  • A lack of vitamin B12 puts your nerves and brain in jeopardy.
  • Individuals who do not consume enough vitamin B12 are more likely to develop psychosis, mania, and dementia.
  • Another symptom caused by a shortage of vitamin B12 is anaemia.
  • The most common symptoms of anaemia are fatigue, shortness of breath, and an irregular heartbeat.
  • Anaemia symptoms include a sore mouth or tongue, weight loss, pale or yellowish skin, diarrhoea, and menstrual problems.
  • Furthermore, vitamin B12 shortage renders people more susceptible to sickness.
  • The Effects of Vitamin B12 on Metabolism
  • Despite the fact that human research is limited, some studies suggest that vitamin B12 may influence body fat and metabolism.

According to one study, vitamin B12, for example, plays an important role in fat metabolism. As a result, a scarcity might lead to an increase in fat and obesity. Acute vitamin B12 deficiency in pregnant mice resulted in a significant increase in body fat percentage and cholesterol levels, according to another animal study.

Furthermore, giving B vitamins to rats on a high-fat diet slowed their weight gain. According to one study, it increased enzyme levels that influence metabolism. However, there is insufficient data. More high-quality research is needed to determine how vitamin B12 influences metabolism specifically.

Obesity has been linked to low vitamin B12 levels.

Surprisingly, adequate vitamin B12 levels have been associated to a lower risk of weight growth and obesity. According to one case study, higher blood levels of vitamin B12 can help prevent obesity.

There were 9,075 adults in the research. Another study of 976 adults indicated that low vitamin B12 levels can increase the likelihood of becoming overweight or obese.

In addition, a study of 256 children discovered that individuals with lower vitamin B12 levels had a higher BMI (BMI). Body mass index (BMI) is a measurement of body size based on height and weight.

Remember that while these studies show a link between vitamin B12 status and body weight, they do not account for other relevant causes.

As a result, it is impossible to prove that vitamin B12 causes weight loss. More research is needed to determine whether vitamin B12 has a direct impact on body weight or BMI.


Vitamin B12 is a water-soluble B complex vitamin that can be found in a variety of foods, including meat, fish, and dairy. Vitamin B12 can be taken orally.

Pernicious anaemia and vitamin B12 deficiency can be treated with injections. Furthermore, several weight-loss clinics incorporate vitamin B12 in their weight-loss programmes. Vitamin B12 injections, on the other hand, are unlikely to deliver an energy boost unless you are deficient in vitamin B12.

Metformin is a medication that can assist people with type 2 diabetes in losing weight. However, as a side effect, this medicine may cause vitamin B12 insufficiency. Talk to your doctor about strategies to maintain your vitamin B12 levels consistent if you’re taking metformin.

Getting large amounts of vitamin B12 by injections is unlikely to be dangerous. However, vitamin B12 can impair the efficacy of several medications. Inform your doctor if you receive vitamin B12 injections.
