Vitamin B12 – All Your FAQs Answered

Vitamin B12 Tablets: Are They Beneficial?

Supplementing with vitamin B12 (together with other B vitamins) lowers homocysteine levels in the blood, a chemical associated to an elevated risk of heart attack or stroke. However, despite lowering homocysteine levels, evidence demonstrates that these vitamins have no effect on the risk of cardiovascular disease or stroke.

Are injections of vitamin B12 safe?

Injections of vitamin B12 are usually thought to be highly safe. There are no significant adverse effects. However, allergic responses or sensitivities can create negative effects in some persons in very rare situations. Consult your doctor if you suffer any negative effects.

How long do the benefits of a B12 shot last for?

In general, vitamin B12 injections have a one-week effect; nevertheless, you should see a healthcare expert to establish how you should administer the injections.

What are the drawbacks of taking B12 injections?

It’s possible that you’ll have pain/redness at the injection site, minor diarrhoea, itching, or a generalised feeling of swelling. Tell your doctor or pharmacist right away if any of these side effects persist or worsen.

Is it safe to have a B12 shot on a regular basis?

Patients who are naturally B12 deficient may benefit from more regular injections, such as once a month. An injection every three to four months may be sufficient for other patients.

What medications should you avoid taking if you’re taking B12?

Other drugs may interfere with vitamin B12 absorption, increasing your risk of insufficiency. Antacids and peptic ulcer treatments, cholesterol-lowering drugs, antiseizure meds, chemotherapeutic medications, the diabetic prescription glucophage (Metformin), and others are among these medications.

Is it necessary to have a prescription for a B12 shot?

Yes, a prescription is required.

What is the ideal location to administer a B12 injection?

When self-administering an IM injection, the middle third of the vastus lateralis muscle of the thigh is the most convenient location. The deltoid muscle in the upper arm and the dorsogluteal location on the bottom are two further possibilities. If you have a caregiver or a family member who is willing to administer your injection, this could be handy.

I’m not sure how many B12 injections I’ll need to feel better.

B12 injections are the most effective approach for your body to absorb Vitamin B12; they act immediately. Your body will start producing new red blood cells in 48 to 72 hours. For minor deficiencies, two to three injections over several weeks may be required to get maximum effect.

How do you feel after you’ve had B12 injections?

An injection is administered into a muscle (known as an intramuscular injection). It’s possible that you’ll have discomfort, swelling, or itching where the injection was given. However, this is usually minor and goes away shortly.

Is it OK to drink alcohol when taking B12 injections?

If you’re taking Vitamin B12, you should avoid consuming a lot of alcohol.

What is the best form of vitamin B12?

Methylcobalamin is the most bio-available form of Vitamin B12, meaning it is more easily absorbed by the body. It is naturally occurring and may be found in animal-based foods such meat, fish, milk, and eggs, making it a staple in many people’s diets.

Are B12 tablets and B12 shots the same thing?

Vitamin B12 tablets may be equally helpful as injections if you have a vitamin B12 shortage. They are easily accessible, less expensive, and can be taken orally. Vitamin B12 injections, on the other hand, are more easily absorbed in the body and do not need to be given as frequently as oral tablets.

Does B12 help with iron deficiency?

B12 is required for the production of red blood cells, which transport oxygen throughout the body. Anemia can develop if you don’t get enough B12, which means your body doesn’t have enough red blood cells to fulfil its function. You may feel weak and exhausted as a result of this.

Is B12 beneficial for reducing abdominal fat?

Although human research is currently limited, several studies suggest that vitamin B12 may have an impact on body fat and metabolism. According to one study, vitamin B12 plays an important function in fat metabolism, and a deficiency has been related to increased fat formation and obesity.

Eat more foods that contain vitamin B12 to boost your vitamin B12 levels in your diet, such as:

Beef, liver, and chicken are among the ingredients.

Trout, salmon, tuna fish, and clams are examples of fish and shellfish.

Breakfast cereal with added vitamins and minerals.

Low-fat milk, yoghurt, and cheese are all good options.


Is the vitamin B12 content of bananas high?

It’s loaded in B vitamins like B6 and B12, as well as magnesium and potassium. It’s also high in fibre and protein.

Is B12 beneficial to your sleep?

Several studies have shown that this vitamin aids in the regulation of sleep-wake cycles by synchronising circadian rhythms.

Is it possible for B12 to increase heart rate?

A rapid heart rate could indicate a vitamin B-12 deficit. To compensate for the lower number of red blood cells in the body, the heart may begin to beat quicker.

Is it possible for a vitamin B12 deficit to produce anxiety?

Mental Symptoms Caused by B12 Insufficiency: B12 deficiency can produce practically every psychiatric symptom, from anxiety and panic to sadness and hallucinations. Because B12 deficiency causes symptoms in the neurological system and red blood cells, this is the case.

How much vitamin B12 should someone over the age of 65 take?

A recent study indicated that a daily dose of 500 micrograms of B12 was effective in curing the symptoms of B12 insufficiency in seniors. For those over the age of 14, doctors prescribe 2.5 milligrammes of vitamin B12 each day.

What is the ideal spot for a B12 patch?

To get the best effects, press the adhesive side of each patch firmly against a venous area of your body, such as your inner elbow, wrist, ankle, or shoulder, so the plant-based nutrients may be easily absorbed.

Do vitamin B12 patches have the same efficacy as injections?

The best solution is to have a B12 injection once a month.

Is B12 good for hair growth?

B12 aids in the creation of oxygen-rich red blood cells, which nourish hair follicles, promoting healthy hair development. Because B12 aids in the production of red blood cells, having enough of this vitamin is critical for hair development.

Is vitamin B12 taken orally effective?

The authors of two studies that compared oral and intramuscular vitamin B12 therapy found that oral vitamin B12 was just as effective as intramuscular treatment.

Is there such a thing as too much B12?

Because B12 is a water-soluble vitamin, even high doses are typically considered safe. Because of its low toxicity, no Tolerable Upper Intake Level (UL) for B12 has been determined. The maximum daily dose of a vitamin that is unlikely to induce harmful side effects in the general population is referred to as the UL.

Is it possible for vitamin B12 to harm your liver?

Vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), and B12 are the most frequent types of vitamin B. (cyanocobalamin). There is no evidence that the other B vitamins, with the exception of niacin (when administered in large dosages), induce liver harm or jaundice in physiologic or even super-physiologic high levels.
