Shrinkage doesn’t just happen at the pool. It can also take place inside your skull, especially when your brain lacks sufficient vitamin B12.
A deficiency of this essential nutrient can cause significant drops in gray matter volume, which has been linked to memory loss. And that’s not all- A slight deficiency of vitamin B-12 can lead to anemia, fatigue, anxiety, and depression, while a long term deficiency can cause permanent damage to the brain and central nervous system.
And according to a new Rush University Medical Center study, low B12 levels often go undetected in blood tests. In fact, even when blood levels of the vitamin appeared normal, between 15% and 17% of people they studied weren’t absorbing enough of the vitamin and had serious deficiencies.
So how can you tell if you are lacking B12? Symptomatology is one way we recognize an increased need for B12 or a decreased absorption of this nutrient and there are other indicators in your blood work that imply a deficiency in B12 (such as homocysteine levels). Or book a live blood analysis test; it is easy to pick out indicators of a deficiency in B12 by looking at the size and shape of your red blood cells in live view.
