Information on B12 Shots

B12 is an essential water-soluble B vitamin. It is crucial to the nervous system and to build red blood cells. It is not found in plant-based foods, so it might be important to those on strict vegan or vegetarian diets to supplement. Memory loss, fatigue and weakness are earlier signs of deficiency. More serious health conditions might develop without proper levels of vitamin B12.

Consideration

• B12 shots might be the best choice when dietary additions or supplements do not digest well.

Solution

• A doctor will assess the need for B12 injections based on a clinical assessment of the patient and might include diagnostic lab work to determine a level of deficiency.

Administration

• B12 shots are typically prescribed and administered by a doctor over the course of several days, after which, a monthly shot might be given.

Benefit

• The effects of B12 shots are usually immediate, resulting in higher energy levels and improved mood and mental function.

Side Effects

• Side effects are generally mild and might include burning or itching at the injection site and mild diarrhea. More serious ones such as trouble breathing, tightness in the chest or other questionable effects should be assessed by a health care practitioner.

Toxicity

• Because excess B vitamins are excreted through urine output, no known toxicity for B12 has been reported.
