Vitamin B12 is just one of the body’s eight B vitamins. Specifically, Vitamin B12 is necessary for ensuring that the red blood cells, the brain functions, and the nerve tissue all remain healthy and productive. The human body does not store this vitamin, but it is water soluble so that it passes easily through the bloodstream. However, sometimes a deficiency can occur, often caused by other health problems, diet or a person’s lifestyle. Unfortunately, B12 deficiency, also known as cobalamin deficiency, can be relatively common, with over 3 million cases in the United States alone. Let’s take a look at some of the symptoms!

1. Loss of Muscle Strength

Things happen every day that can cause a person to lose the feeling of strength in their muscles. You can take on a more demanding schedule at work, or you can start a vigorous new workout program. However, if you are finding it hard to bring in the groceries after a trip to the store, then there could be an underlying reason why your muscles are not performing in the way that they typically do. When a lack of vitamin B12 is constricting the amount of oxygen in your red blood cells, then this can affect your muscle strength to varying degrees.
