Everything You Need to Know About Vitamin B12

Nov 10th, 2020 by Blood Type Diet

Vitamin B12 is an essential vitamin that your body needs to thrive but is unable to produce on its own. It is found naturally in animal products, such as meat, fish and dairy, and is also readily available in supplement form.

This important vitamin is critical to the body’s metabolic function and energy production. It even helps to create DNA, the genetic material in every cell of the body.

Read on to learn more about this powerhouse vitamin.

Why you need vitamin B12

Your body needs vitamin B12 to function properly. It plays an essential role in the formation and metabolism of your red blood cells. It also helps maintain the overall health of your nerve cells and works to form their protective covering, known as the myelin sheath. And as if that weren’t enough, this dynamic nutrient does so much more.

Vitamin B12 helps to maintain normal brain function and support healthy bones. It’s important for eyesight, healthy skin, hair and nails, and prevents certain types of anemia. It’s even known to improve your memory, your mood and your energy level! You could say that vitamin B12 is like a superhero of vitamins. And, you must get vitamin B12 through the foods you eat, or through supplementation, which leads to the natural question, “What happens if I don’t get enough?”

Symptoms of vitamin B12 deficiency

Fortunately, most people in the U.S. get enough vitamin B12 in their diets, but as we age, it can become more difficult to absorb. Also, people with certain immune system disorders or conditions that affect the small intestine, such as Crohn’s disease, may be more likely to develop a deficiency. For those who eat a vegan diet, it is important to look out for a B12 deficiency since the vitamin is found primarily in meat and dairy products.

Some symptoms of vitamin B12 deficiency include feeling weak, tired or lightheaded. Some people experience nerve problems such as numbness or tingling in the hands and feet, muscle weakness or difficulty walking. Depression and memory loss can also be symptoms, as can pale skin or loss of appetite. People with a vitamin B12 deficiency can even become anemic. Fortunately, a B12 deficiency can typically be reversed with vitamin supplements.

Best sources of vitamin B12

Vitamin B12 is found in animal products. Organ meats such as liver and kidneys are rich in vitamin B12. Beef and chicken are also excellent sources. And for those that prefer to get their nutrients from the sea, fish, particularly trout, salmon, tuna, sardines and shellfish also have a high vitamin B12 content.

It’s not only meat that contains B12. Eggs and dairy products, such as milk, yogurt and cheese, also contain high levels of this essential vitamin. Some items are fortified as well, for example certain nondairy milk substitutes and certain cereals.

All B12 vitamins are not the same

When it comes to vitamin B12, it’s important to recognize that not all forms are the same. The most common form found in supplements is called cyanocobalamin, which is a manufactured form that is not derived from animals or from plants. As its name implies, it contains a cyanide molecule, not in a harmful amount, of course, but is still something that your body has to remove through detoxification.

Two other available forms are naturally occurring: methylcobalamin and adenosylcobalamin. The names may be tongue twisters, but all you really need to know is that they are considered to be more active and they do a better job of generating the chemical reactions needed for good health. Each one has slightly different health advantages, but both are better absorbed and retained in the tissues in higher amounts than the cyanocobalamin form.
