Yes, headaches and dizziness are common symptoms of a vitamin B12 deficiency. These symptoms often occur because a lack of B12 can lead to anemia and affect nerve function.
It is believed that vitamin B12 deficiency and hyper-homocysteinemia cause endothelial cell damage by increasing the levels of free oxygen radicals, which may, in turn, be related to the onset of migraine episodes. It is also believed that nitric oxide (NO) plays a role in the pathology of migraine (1, 2).
The worst symptoms of B12 deficiency involve severe neurological damage, including severe memory loss, confusion, dementia, psychosis, hallucinations, balance problems, trouble walking, and irreversible nerve damage (neuropathy), alongside serious mental health issues like severe depression or irritability, with physical signs including extreme fatigue, pale skin, and a sore, smooth tongue. These severe cognitive and neurological issues are the most concerning because they can become permanent if left untreated.
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.
Taking doses of vitamin B-12 might cause: Headache. Nausea. Diarrhea.
Neurological changes
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.

Key points about vitamin B12 deficiency anemia
Without enough red blood cells, your tissues and organs don't get enough oxygen. Without enough oxygen, your body can't work as well. Symptoms include weak muscles, numbness, trouble walking, nausea, weight loss, irritability, fatigue, and increased heart rate.
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 deficiency can also cause symptoms that affect your brain and nervous system (neurological symptoms), including: numbness. muscle weakness. psychological problems, which can range from mild depression or anxiety, to confusion and dementia.
Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
Magnesium Deficiency
Neurologist Dr. Joshua Daniel of Shore Physicians Group said many migraine headache sufferers are found to be deficient in magnesium when they have blood work done.
Optic neuropathy is reported to occur in less than 1% of VitB12 deficient patients. It mostly results in progressive, bilateral, painless loss of vision associated with abnormal color vision and central or ceco – central scotomas.
Not diet-related
If your vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, you'll usually need to have an injection of hydroxocobalamin every 2 to 3 months for the rest of your life.
Outcome and Management. The severity of liver injury from amlodipine ranges from mild and transient serum enzyme elevations to self-limited jaundice. Complete recovery is expected after stopping the drug and recovery is usually rapid (4 to 8 weeks).
Some studies have found that taking medications like amlodipine in the evening helped lower blood pressure better than morning doses. Other studies have found that nighttime doses cause blood pressure to drop too low overnight.
Recently, some researchers have questioned the benefit of amlodipine for treating hypertension. Studies suggested that amlodipine may activate a different type of calcium channel, resulting in changes to blood vessels and an increase in heart failure in patients.
Before starting the Vitamin injections I will make sure to tell my Physician if I am pregnant, lactating or have any of the following conditions.
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.
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.
Dizziness has many possible causes. These include conditions that affect the inner ear, motion sickness and medicine side effects. Very rarely, dizziness may be caused by a condition such as poor circulation, infection or injury.
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.
Fatigue and weakness
Chronic fatigue is one of the most common and overlooked signs of vitamin deficiency. If you find yourself constantly tired, even after a good night's sleep, a lack of vitamin B12 might be to blame.
