You should not take vitamin B12 if you have a known allergy to vitamin B12 or cobalt, suffer from Leber's disease, or are taking medications that could have negative interactions. It is important to consult a doctor before starting any new supplement.
Possible interactions include:
Vitamin B12 is a nutrient that supports healthy nerve and blood cells. It also helps you make DNA, your body's genetic material, that are present in every cell. B12 also helps prevent megaloblastic anemia, which is a blood condition that can make people feel tired and weak.
B12, vitamin B-12. supplementation can effectively reduce uric acid concentrations or can reduce the risk of hyperuricemia.
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.
While vitamin B12 is generally safe, taking excessively high doses, especially via injections, can cause side effects like headaches, nausea, diarrhea, dizziness, and skin rashes; rare serious issues include allergic reactions (anaphylaxis), increased heart rate, blood clots, and potential links to increased cancer risk or early death, requiring medical attention if severe symptoms appear.
Yeditepe University Hospitals Otolaryngology and Head and Neck Surgery Specialists, who drew attention to the latest research, said "Iron deficiency anemia, vitamin B12 and D deficiency cause vertigo". The most common inner ear disease causing vertigo is Benign positional paroxysmal vertigo.
Two common types of GERD medicines have been linked to vitamin B-12 deficiency:
Symptoms of high uric acid (hyperuricemia)
Vitamin B-12 acts as an antioxidant or anti-inflammation agent, which might modulate oxidative stress responses, including those of inflammatory responses [10,11,12,13,14].
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.
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].
Studies show that high vitamin B12 levels may be associated with a lower risk of having obesity, but, again, that doesn't mean that getting vitamin B12 shots will help you lose weight. “If your B12 level is normal, there is little evidence to support that they actually work for these purposes,” Dr. Goodman states.
Common conflicts include calcium with iron or magnesium, zinc with iron or magnesium, and vitamin C with B12 or copper. Spacing doses prevents deficiencies and adverse effects. Supplements may also interact with medications, like calcium with thyroid drugs or herbal products with blood pressure medicines.
There is general consensus that gastric acid–lowering drugs, including proton pump inhibitors (PPIs) and H2-receptor antagonists (H2RAs), and the antidiabetes drug metformin can reduce circulating vitamin B-12 concentrations with prolonged use.
When uric acid levels in the blood become too high, it can seep out and form crystals in the spaces around the joints, causing intense pain and swelling. The pain often comes on suddenly and unexpectedly (thus the term, “attack”) and can last from a few days to a few weeks.
Lemon water:
Squeeze fresh lemon juice into a glass of warm water and drink it in the morning on an empty stomach. Lemon water can help alkalize the body and support the elimination of uric acid.
A uric acid test can also be performed at home. Special tools, like uric acid test strips, allow you to take a blood sample by pricking your finger to measure uric acid levels. However, some experts do not recommend this method due to a lack of supporting research.
Gastric acid inhibitors
These drugs can interfere with vitamin B12 absorption from food by slowing the release of hydrochloric acid into the stomach, leading to vitamin B12 deficiency. Gastric acid inhibitors include omeprazole (Prilosec), lansoprazole (Prevacid), cimetidine (Tagamet), and ranitidine (Zantac).
Vitamin B12 itself is vital for energy production, red blood cell formation, and nerve function. Typically, B12 cocktails include a mix of B12 injections or supplements, coconut water, citrus fruits, and other natural ingredients known to aid in weight management.
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.
People need vitamin B-12 for the brain to work well. If not treated, vitamin B-12 deficiency can lead to issues with the nerves, brain or spinal cord. These might include lasting tingling in the hands and feet or trouble with balance.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
“It is caused by crystals inside the inner ear being dislodged from their normal positions. Most vertigo are 80% or 90% peripheral causes or ear causes. And then about 10% or 20% are the central causes.”
