Feeling tired all the time can have many causes. For some people, low vitamin B12 is part of the picture. In this guide, we explain what B12 does, who is more likely to run low and how vitamin B12 injections work at Allure.
What Does Vitamin B12 Do?
Vitamin B12 helps keep your blood and nerve cells healthy. It also helps your body make DNA. According to the NIH Office of Dietary Supplements, most adults need 2.4 micrograms a day.
Because the body cannot make B12, you get it from foods such as meat, fish, eggs and dairy, or from fortified foods and supplements.
Who Is More Likely to Have Low B12?
- Adults over 50, since stomach acid often drops with age
- Vegans and vegetarians who eat few animal foods
- Anyone who has had stomach or weight loss surgery
- People with celiac disease or Crohn’s disease
- Those who take metformin or acid-reducing medicines for a long time
In these cases, the body may not absorb enough B12 from food. As a result, a provider may check levels or suggest other options.
Signs of Low Vitamin B12
Low B12 can cause tiredness, weakness, pale skin and numbness or tingling in the hands and feet. It can also affect balance, mood and memory. However, these signs can have other causes too, so it is best to talk with a provider instead of guessing.
How Vitamin B12 Injections Work
An injection places B12 into the muscle, so it does not depend on absorption in the gut. That is why the NIH notes that a prescription B12 shot is often used to treat B12 deficiency. At Allure, a team member gives the injection in just a few minutes.
Also, Allure offers other options, such as B-Complex and lipotropic injections. You can see the full list on our Vitamin & Wellness Injections page.
What to Expect at Your Visit
