Vitamin B12 is a water soluble vitamin that plays an important role in several functions in the body such as red blood cell production and normal nerve and muscle function. B12 is a vitamin used to treat vitamin B12 deficiency in people with pernicious anemia and other conditions.  Vitamin B12 is a an essential vitamin found in foods of animal origin such as meat, eggs and dairy.  Vegetables provide a poor dietary source for vitamin B12.  Deficiency in B12 in healthy individuals is rare.  However, as we age our ability to adequate absorb B12 from our diet diminishes and medications we take may also interfere with our ability to absorb B12.  Strict vegetarians/vegans and patients with malabsorption problems are more likely to become deficient.  If left untreated anemia can occur.  Vitamin B12 deficiency can also lead to abnormal neurologic and psychiatric symptoms including shaking of the extremities and unsteady gait, muscle weakness, decreased sensation (neuropathy), incontinence, vision problems, dementia, psychosis, and mood disturbance.

How often should I receive Vitamin B12 injections?

Everyone’s body chemistry is different and therefore the number and frequency of vitamin B12 injections can vary between patients.  Typically patients that have a documented vitamin B12 deficiency will require 1-2 injections of vitamin B12 a week for the first 1-2 months and then monthly injections to maintain levels thereafter.  Often times dosing and frequency of treatments is based on patient’s reported symptoms. 

Do you check blood work prior to or after Vitamin B12 injections?

We do not check blood work prior to or after Vitamin B12 injections.  The use of B12 injections in the medical spa industry are intended as an overall supplement to one’s health.  Improvement in one’s symptoms is subjective.  Patient’s individualized treatment schedules are determined based on their reported concerns and symptoms.  We do ask that patients maintain a routine relationship with a primary care provider which generally requires annual blood work as well as a routine annual physical exam as it is important to report any changes in one’s medical health prior to treatment.

Can I get toxic from too much Vitamin B12?

Elevated B12 levels that are the result from taking oral, nasal, or injected forms of vitamin B12, known as exogenous forms, are unlikely to cause any serious harm since B12 is a water soluble vitamin.  Generally 50-60% of the vitamin is excreted by the body within the first 48 hours of injection or ingestion.  Elevated B12 levels not related to taking “exogenous” or supplemental forms of vitamin B12 should be evaluated by a medical professional.
