Too much vitamin B12 typically doesn't cause severe issues as the body excretes the excess, but it can lead to mild symptoms like headaches, nausea, diarrhea, weakness, tingling in hands/feet, skin rashes (acne/rosacea), and potentially mood changes or heart palpitations, especially with very high doses from supplements or injections. While generally safe, very high levels might be linked to increased risk for some cancers or bone fractures in rare cases, but evidence is mixed.

People may experience frequent episodes of dizziness with no apparent cause. Headaches may be persistent and more intense than common tension headaches.
Digestive disturbances: Symptoms may include loss of appetite, nausea, and diarrhea. Headaches, rashes, and itching. Numbness or weakness in the arms, legs, and facial muscles.

Stay Hydrated: Drink plenty of water to help your body eliminate excess Vitamin B12 through urine. Monitor Underlying Health Conditions: If elevated B12 is linked to liver or kidney problems, adhere closely to your doctor's prescribed treatment plan.
This study provides suggestive genetic evidence for the causal relationships between serum vitamin B12 concentrations and risk of anxiety and bipolar affective disorders. Specifically, genetically determined higher vitamin B12 is associated with a higher risk of anxiety and bipolar affective disorder.
For example, vitamins B6 and B12 play a key role in energy metabolism. However, taking large doses of these vitamins can also cause fatigue and other symptoms such as headaches, diarrhea, and nausea. Other vitamins that have been linked to fatigue include vitamin C and iron.

The observed reduction in pruritus severity in our meta-analysis may be attributable to these anti-inflammatory effects, suggesting that vitamin D could be particularly beneficial for patients with inflammatory skin conditions.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
For temporary relief of itching, try these self-care measures:
Individuals experiencing a deficiency often report feeling unusually tired or weak, even after adequate sleep. This symptom arises because a lack of B12 impairs the production of red blood cells, leading to fewer cells to transport oxygen throughout the body.
Symptoms of vitamin B12 or folate deficiency
extreme tiredness. a lack of energy. pins and needles. a sore and red tongue.
Low serum concentrations of vitamin B6 and iron are related to panic attack and hyperventilation attack.
Vitamin B12 is a water-soluble vitamin, which means the body usually gets rid of the extra amounts through urine. High B12 levels can be caused by various factors, such as taking large amounts of supplements, eating a diet high in B12-rich foods, certain medical conditions, and some genetic factors.
Studies have documented a positive correlation between elevated levels of B12 and the incidence of lung, pancreatic, and liver cancers, as well as certain hematological neoplasms, particularly those related to the myeloid lineage.
In conclusion, our results show that lower vitamin B12 was associated with insomnia symptoms and sleepiness in specific groups of participants. However, further research with objective measurements of sleep is crucial to assess the relationship between sleep and vitamin B12.
If you don't have a vitamin B12 deficiency, most of the vitamin B12 you get through your injection will be absorbed and eliminated quickly through your urine. This accounts for the people in the research that found 98% of their injected vitamin B12 in their urine 48 hours after it was administered.
