You can get a B12 injection without a diagnosed deficiency, especially if you're vegan, older, pregnant, have absorption issues (like Crohn's), or feel tired, as some clinics offer them as wellness boosts; however, unless you truly have low levels, the benefits (energy, mood) are likely minimal, possibly just a placebo effect, and it's best to consult a doctor first to confirm a need via blood test, as injections are usually for treating confirmed deficiencies, sayNarangba Station Medical Centre, Healthline, Medical News Today, Save Face.
Vitamin B12 shots are openly advertised as a quick fix option to boost energy and metabolism, and in some cases claim to help you to shed weight. Unless you have a B12 deficiency, however, the additional injection is unlikely to give you an energy boost, and there is no evidence to suggest it can aid weight loss.
No direct, significant interactions are widely reported between Vitamin B12 and amlodipine, but it's crucial to consult your doctor because general vitamin supplements (especially multivitamins with minerals) can affect blood pressure medications, potentially reducing amlodipine's effectiveness, and your healthcare provider knows your full health picture. Always discuss all supplements with your doctor before combining them with amlodipine.
Generally safe. Most people get enough vitamin B-12 from a balanced diet. But older adults and people who follow vegetarian or vegan diets may find it helpful to take vitamin B-12 supplements.
Yes, Vitamin B12 can help with vertigo, especially if a deficiency is the underlying cause, as low B12 levels can lead to neurological problems, anemia, poor nerve function, and reduced blood flow to the brain, all contributing to dizziness and imbalance, with supplementation showing promise in improving symptoms.
Benign Paroxysmal Positional Vertigo (BPPV) has been linked with low vitamin D levels for many years. While BPPV typically occurs without a known cause, decreased levels of vitamin D in the blood has been associated with increased recurrence of BPPV (1).
While Vitamin B12 is generally safe, potential disadvantages (side effects) can occur, especially with high doses or injections, including headaches, nausea, diarrhea, weakness, skin issues (rash, itching), and rarely, more serious heart or allergic reactions (like anaphylaxis), though toxicity from oral intake is rare as excess is usually excreted. Conversely, a deficiency can cause serious problems like irreversible nerve damage, memory loss, fatigue, infertility, and increased risk of certain cancers, making proper intake crucial.
If you feel constantly tired and your levels of B12 are low, bringing them up to normal may give you more energy, studies show. But B12 supplements don't seem to have any effect on people already at normal levels.
Vitamins B9 and B12 are both thought to treat symptoms of anxiety. Folic acid has many uses in the body, and a vitamin B9 deficiency has been linked to higher levels of anxiety and depression. When taken in conjunction with B12, these B super-vitamins help metabolize serotonin, which is important for mood regulation.
In fact, some studies have even suggested the opposite. For instance, one study noted that individuals who regularly took vitamin B12 supplements gained between 2.5 to 17 fewer pounds (1.2 to 7.7 kg) over a decade than those who didn't supplement.
That said, there are no known risks of taking Vitamin B in combination with blood pressure medication, as long as you are treating a vitamin deficit and not going above the recommended daily dose.
Common side effects
CALCIUM CHANNEL BLOCKERS
Examples include; amlodipine, nifedipine, felodipine, diltiazem and verapamil. Nutrients that can be depleted by these medicines are potassium, calcium, vitamin D and possibly Co-Enzyme Q10.
Vitamin B-12 is added to some foods and is available as a dietary supplement. Health care providers commonly prescribe vitamin B-12 shots to help prevent or treat pernicious anemia and B-12 deficiency.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
Your doctor likely stopped B12 injections due to following standard guidelines suggesting oral supplements or for reasons like cost/logistics (especially during the pandemic), but this can be risky; the main reasons are often a perceived 'normal' blood test (which doesn't always reflect cell levels) or a guideline shift, but you may still need injections for neurological symptoms or poor absorption, so discuss your symptoms urgently with your doctor and ask for clear evidence for the change.
Heart Health
Vitamin B12 protects against cardiovascular disease including heart attack and stroke. It does this by lowering the levels of an amino acid in the blood called homocysteine. High homocysteine levels are associated with the development of heart disease.
Teas for stress and anxiety relief
Consider stopping treatment if: The person's symptoms have resolved or improved and the cause, or suspected cause, of the vitamin B12 deficiency has been addressed (for example, the person has increased their dietary intake of the vitamin).
If you are not deficient, I believe it is safe to take a B12 supplement at a lower dose; you don't even have to take it every day because B12 is well-stored by the body.
Particularly, individuals with lung, stomach, colon, oesophageal, and pancreatic cancers are more prone to experiencing a deficiency in vitamin B12. This article will discuss different types of cancers causing vitamin B12 deficiency, associated symptoms, and available treatment options.
Symptoms of vitamin B12 and folate deficiency anaemia include:
Active B12 is generally considered to be the best form of B12 for seniors for several reasons. Metabolically active forms of B12 such as methylcobalamin and adenocobalamin require no further conversion in the body.
The foods highest in Vitamin B12 are animal products, with clams and liver (beef, lamb) being exceptionally rich sources, often providing several hundred percent of the daily value in a single serving, alongside seafood like mussels, sardines, and salmon, dairy, eggs, and fortified cereals and nutritional yeast for vegans.
