Recently, there has been a mass hysteria about B12 depletion in farming soil, low B12 levels, and people pretty much saying that we are all going to die because the level of B12 in the soil is lower than it was 100 years ago.
Because of the paranoia, people are demanding blood tests to determine whether they are actually low in B12. Even with a lab test, you cannot truly determine your B12 level because your true B12 level cannot be reflected by serum levels that are tested.
Vitamin B12 is an important nutrient. It helps the body in so many ways, from keeping the body’s nerve cells healthy, keeping the body’s blood cells healthy, and helps create the genetic material that creates DNA. Maintaining a healthy level of B12 can prevent the development of megaloblastic anemia, a type of anemia that can make someone feel extremely tired. However, the only way to determine whether you have a deficiency severe enough to cause physical symptoms is through blood tests.
The reason these laboratory results are inaccurate is because B12 is not stored in the blood, it is stored in the liver. Without directly testing the liver and risking your life doing so, you cannot truly know how much of this vitamin is stored within your body.
The vitamin B12 is stored from infancy until the day we die. We accumulate it through leafy greens, multivitamins and many other ways. There is almost no chance that your body will run out of B12, and if you are afraid that you may be low in a certain vitamin, take a daily multi-vitamin.
While doctors do not openly admit it, the concept of medicine is not an exact science. It is actually referred to as “practicing medicine.” Add to this that everyone’s body is different and has different needs, and the fact that stressing and waiting to have blood work done can actually affect the result of your lab levels, something is guaranteed to comeback as abnormal.
The best way to ensure that you are getting enough of the vitamins you need is to eat a healthy, balanced diet and take a high-quality multivitamin every day.
