Is a B12 Shot Right for You? Signs You May Benefit From This Vitamin Boost
Vitamin B12 is an essential nutrient that plays a key role in red blood cell formation, cellular metabolism, nerve function, and DNA production. Because the body does not produce B12 on its own, the nutrient must be derived from foods or supplements. For most adults, experts recommend consuming 2.4 micrograms (mcg) of vitamin B12 per day.
Most people get enough vitamin B12 from the foods they eat, such as meat, fish, poultry, and dairy products. However, those who follow a vegan or vegetarian diet are prone to deficiency because plant foods do not contain vitamin B12. Additionally, older adults and those with digestive issues that interfere with nutrient absorption may also become deficient.
Are You Getting Enough B12?
The symptoms of vitamin B12 deficiency usually develop gradually and worsen over time. Signs to watch for include:
- Unexplained fatigue
- Persistent nausea, vomiting, or diarrhea
- Loss of appetite
- Unintended weight loss
- Yellowish skin
- Sore mouth or tongue
- Depression or irritability
- Behavioral changes
- Numbness and tingling sensations in the hands and feet
- Vision changes
- Mental confusion
Should You Consider a B12 Shot?
If you have symptoms of vitamin B12 deficiency, you should see a medical provider for a proper diagnosis, which usually involves blood testing. After confirming your diagnosis, your provider may suggest vitamin B12 oral supplements, nasal gel or spray, or intramuscular injections (B12 shots).
A B12 shot delivers a high dose of vitamin B12 directly into a muscle. From there, the nutrient is gradually released into the bloodstream over time. Because B12 shots bypass the digestive system and allow for complete nutrient absorption by muscle tissue, they are a fast and effective way to address a deficiency. Some people experience symptom improvement within several weeks after an injection.
