Vitamin B12 is crucial for our body to make DNA for new cells, form healthy red blood cells, and turn the food we eat into energy to power our metabolism. Its deficiency may be the most overlooked link in many health issues.
Why is a lack of B12 of such concern? In the short term, insufficient B12 levels can lead to deep fatigue, mood changes, poor memory, focus problems, and dementia, preventing you from feeling your best and performing at your highest energy level. In the long term, an unchecked vitamin B12 deficiency can lead to permanent nerve damage and premature aging!
Vitamin B12 is essential for the manufacture of red blood cells; a deficiency leads to anemia. It is needed to support the normal function of nerve cells, and to manufacture myelin, the insulating material that surrounds some of our nerve cells and speeds neural transmission. Vitamin B12 is also required for the replication of DNA, without which we can’t generate new, healthy cells.
Having low levels of vitamin B12 will not only compromise your immunity but also lower your energy levels, potentially making you feel tired and depressed. Low levels of B12 also alter your ability to think clearly and make you age faster!
Great sources of vitamin B12 are clams, liver, fish, yogurt and cheese. Since most people can't get enough from diet alone, it's a good idea to take a daily vitamin B supplement or multivitamin.
