Vitamin B12 has undoubtedly gained a lot of public attention in recent months – and rightfully so. This fascinating member of the B vitamin family, whose complete chemical structure was only deciphered in 1960, has been the subject of intensive scientific research, some of which has earned Nobel Prizes. Yet for a long time, B12 remained misunderstood and overlooked by modern medicine.
Why does our body need vitamin B12?
So what exactly makes B12 so important? At the core of its molecular structure lies cobalt – which is why it’s scientifically known as cobalamin. This cobalt content is essential for the proper functioning of the nervous system and the brain. Vitamin B12 helps form red blood cells, which carry oxygen and nutrients to every cell in the body. It also plays a role in DNA synthesis and regulation, the production of fatty acids, and maintaining our energy levels. Through B12, the body also synthesizes succinyl-CoA – a key component in hemoglobin production.
B12
Like all vitamins, B12 cannot be produced by the body and must be obtained through food or supplements. Unlike fat-soluble vitamins like A, D, and E that can be stored in the body, B12 is water-soluble. This means that any excess is flushed out through bodily fluids, and we must replenish it daily.
Even though the required daily amount is very small – between 2 and 4 micrograms – B12 is often difficult to absorb. For people over the age of 50, a common issue is atrophic gastritis – inflammation of the stomach lining, which reduces the secretion of stomach acids necessary to release B12 from food proteins. Other contributing factors include digestive issues, autoimmune inflammation, alcohol consumption, antacid medications, diabetes drugs, antidepressants, and more.
Getting enough B12 is even more challenging for vegetarians and vegans since the richest sources of this vitamin come from animal products. Foods high in B12 include clams, liver, mackerel and other fish, octopus and shellfish, beef, lamb, chicken, cheese, low-fat milk, and eggs. This means that people following plant-based diets should rely on fortified foods (like tofu and breakfast cereals) or take supplements to meet their B12 needs.
Even a mild deficiency in B12 can lead to anemia, chronic fatigue, and even depression. In the long term, a lack of B12 can cause cardiovascular problems and lasting damage to the brain and central nervous system. It can also impair red blood cell function, which may lead to cellular mutations and DNA damage. The risk of developing osteoporosis also increases.
Some of the symptoms that might indicate a B12 deficiency include low energy, drowsiness, irritability or aggression, balance issues, tingling or numbness in the body, forgetfulness, weight loss, chronic fatigue, and many others. That’s why, if you're feeling unwell and suspect your B12 levels may be low, don’t hesitate to consult your doctor and create a nutrition plan tailored to your body’s needs.
