Yes, you can absolutely buy Vitamin B12 over-the-counter at pharmacies, including major chains like Chemist Warehouse and Priceline, as well as online, in various forms like tablets, lozenges, or sprays, to support energy, nerve function, and blood health. While oral supplements are common and affordable, injections are available through specific health clinics for those needing them, notes Superdrug Health Clinic.
Vitamin B12 tablets, also known as cyanocobalamin, can be bought over the counter from pharmacies or health stores, but are not as effective as the injection.
Food sources of vitamin B-12 include poultry, meat, fish and dairy products. Food companies also may add vitamin B-12 to breakfast cereals. Some people may take it as a vitamin by mouth. Healthcare professionals might prescribe vitamin B-12 injectio ns or nasal spray to treat people with very low vitamin B-12 levels.
An increase of one unit in vitamin B12 was associated with a 1.04% decrease in hemorrhoid occurrence. Conclusion: This study suggests that evaluating homocysteine, copper, folate, and vitamin B12 levels may be valuable in patients with or at risk of hemorrhoidal disease.
Pharmacists can administer intramuscular vitamin B12 treatment where there is a therapeutic need, they are suitably qualified and all professional obligations are met.
B12 Vitamin overdose is not just connected with implications on your physical health, but it also has a negative impact on your mental health. Taking B12 without consulting your doctor may lead to restlessness, depression, mood swings, and even panic attacks.
Vitamin B12 deficiency symptoms develop gradually and include extreme fatigue, pale skin, shortness of breath, headaches, and nerve issues like numbness or tingling in hands/feet, plus cognitive problems such as memory loss and confusion, often linked to anemia but also affecting nerves and brain function, requiring medical diagnosis and treatment.
What is vitamin B12 and what does it do? Vitamin B12 is a nutrient that helps keep your body's blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.
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.
Additionally, supplementing vitamin C can support the formation and maintenance of healthy blood vessels, which is very good for hemorrhoid patients. Moreover, vitamin E has anti-inflammatory effects, effectively healing damaged tissues and reducing hemorrhoid clusters.
High Dosage
Injections typically provide a much higher dose of Vitamin B12 compared to oral supplements. This can benefit individuals with severe deficiencies or those needing a quick boost in their B12 levels.
If you have vitamin B12–deficiency anemia, you may have the typical symptoms of anemia at first, such as fatigue, paleness, shortness of breath, headaches, or dizziness. If left untreated, you may start to notice brain and nervous system symptoms.
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.
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.
Milk. One of the best drinks with B12 is milk. One cup of whole milk contains approximately 1.32µg of vitamin B12.
To quickly increase B12, focus on animal products (meat, fish, dairy, eggs) and fortified foods (cereals, plant milks, nutritional yeast), but for a significant deficiency or rapid boost, especially if dietary changes aren't enough, consult a doctor for high-dose supplements or B12 injections, as severe cases require medical intervention for proper absorption and treatment, note NHS and Healthline.
Apples and bananas help improve gut health, supporting better B12 absorption. Some fortified fruit juices (like orange juice) may include added B12.
Vitamin B12 deficiency can also cause symptoms that affect your brain and nervous system (neurological symptoms), including:
Vitamin B12 is required for the development, myelination, and function of the central nervous system; healthy red blood cell formation; and DNA synthesis [1,4,5]. Vitamin B12 functions as a cofactor for two enzymes, methionine synthase and L-methylmalonyl-CoA mutase [1-3,5].
The Boots Vitamin B12 Blood Test Kit checks your vitamin B12 levels, using a finger-prick blood sample. Use of this kit requires internet access. All personal data in relation to this product, services and online platforms are collected and processed by MyHealthChecked.
Causes of Vitamin B12 deficiency
The best form of B12 is often considered methylcobalamin, as it's a naturally occurring, active form the body uses immediately, though adenosylcobalamin is also an active form, with a combination often recommended for better results, especially for deficiency or absorption issues, while cyanocobalamin, a cheaper synthetic option, is effective but requires conversion and is less ideal for some. For general supplementation, natural forms like methylcobalamin or adenosylcobalamin are preferred for better retention.
