Amazing Benefits Of Vitamin B12 For Hair, Skin And Health

A vitamin B12 deficiency is thought to be one of the leading nutrient deficiencies in the world, with a 2004 study showing that it’s a major health concern in many parts of the world, including the U.S, India, Mexico, Central America, South America and certain areas in Africa.

Vitamin B12 benefits your mood, energy level, memory, heart, skin, hair, digestion and more. Vitamin B12 is also an essential vitamin for addressing adrenal fatigue, multiple metabolic functions — including enzyme production, DNA synthesis and hormonal balance — and maintaining healthy nervous and cardiovascular systems.


Because of its wide-reaching roles within the body, a vitamin B12 deficiency can show up in many different negative symptoms, many of which are very noticeable, such as potential chronic fatigue, mood disorders like depression, and chronic stress or feeling run down.

What is Vitamin B12?

  • Vitamin B 12, also known as Cobalamin, is one of the 8 vitamins found in vitamin B complex. All B group Vitamins are required to convert food into fuel to produce energy but vitamin B 12 also plays an important role in regulating metabolism. This makes Vitamin B12 an essential nutrient found especially in animal sources of food.
  • These are water soluble and delicate. They get destroyed easily when cooking or by consumption of alcohol. Food processing also reduces the amount of Vitamin B in foods.
  • However, this vitamin does have a difference from the remaining of the complex. This is the only water soluble vitamin that is stored in large quantities in the liver for years.
  • The daily requirement of Vitamin B12 varies from person to person. Strict vegetarians, heavy drinkers, smokers, pregnant ladies and elderly people usually require more doses of Vitamin B12 than others.
  • People with a liver or kidney condition and sufferers of haemolyticanaemia also require a bit more of Vitamin B12 than others.
  • RDA recommends at least 2.4 micrograms of Vitamin B12 per day.

Vitamin B12 Benefits and Food Sources

brain-tobeingfitVitamin B12 benefits the central nervous system in many important ways: It helps maintain the health of nerve cells — including those needed for neurotransmitter signaling — and helps form the protective covering of nerves, called the cell’s myelin sheath. This means that when vitamin B12 levels are low, almost every cognitive function can suffer.

Vitamin B12, sometimes also called cyanocobalamin, also helps with digestion and heart health, so a deficiency can lead to both digestive disorders and an increased risk for heart disease.

The National Institute of Health’s (NIH) Dietary Office estimates that somewhere between 1.5–15 percent of people in the U.S. are deficient in vitamin B12.  Other studies, like one done by the American Journal of Clinical Nutrition in 2000, indicate that this number might be even higher, with up to 39 percent of the population possibly suffering from a vitamin B12 deficiency.

Animal foods are the best food sources of vitamin B12, including organic grass-fed dairy products, cage-free eggs, grass-fed meat, wild-caught fish, organic poultry and organ meats. According to the NIH, plant foods do not naturally contain vitamin B12 unless they are synthetically fortified.

Vitamin B12 can be found to some degree in fortified plant foods like nutritional yeast, fortified grain products and algae sea vegetables. However, most of these are not thought to be nearly as absorbable as natural animal sources are.
