It can also help maintain hair’s colour and encourages growth of hair.

This is why the main sign for B12 deficiency is fatigue breathlessness, fatigue, and fatigue.

  1. It is essential for a good brain and nervous system functioning.

  4. It helps maintain bone health and can help aid in preventing osteoporosis.
  5. It also promotes healthy hair, skin and nails.
  6. Because of its role in the creation of serotonin it aids in improving mood and general sense of wellbeing.

Why B12 Deficit Causes Greying and Hair Loss



The hair we grow grows every day as hair cells multiply and divide which push the hair up and out of the skin’s surface. Hair cells can be imagined growing as Lego blocks. The only difference is that it’s creating from the upside down.

Comparatively to other cells in the body hair follicles are among the most rapidly growing cells. They are also dependent on a steady supply of nutrients. One of these is B12 which is essential to synthesize DNA. Without B12, the instructions to build cells are not complete, and the cells cannot multiply and grow.

Thus, when the levels of B12 drop, hair cells won’t be able to grow properly. This could cause the hair’s growth to slow and in some instances, to cease completely. Additionally, the absence of B12 impacts overall health, and if you’re sick your hair won’t flourish. It’ll also be affected.

The good news is that , once Vitamin B 12 levels are restored, hair cells will be able grow and reproduce in a healthy way. The hair you lost may grow back within just a couple of months.

What happens when B12 deficiency turns hair Grey

The body’s interconnected — one substance goes down, and the other increases. Therefore, balancing is essential. When B12 levels drop then those levels of homocysteine** increase.

Homocysteine levels that are elevated are not healthy for our health and hair. The reason for this is that the high levels of homocysteine has been known to produce hydrogen peroxide, which actually bleaches the hair from within and turns your hair grey.

Research studies have proven that vitamin B12 can reduce homocysteine levels. It could assist in reversing graying and restore the original color.

*Homocysteine is an byproduct of the metabolism of proteins that is cleared by the body by utilizing vitamin B12. A higher homocysteine concentration is an indicator of risk in heart diseases, Alzheimer, and stroke.

What Foods contain Vitamin B12? Grilled Salmon: A good source of Vitamin B12

Plants aren’t able to make vitamin B12.

It’s produced by microscopic organisms and bacteria that reside in soil. When animals that eat grass (such as sheep and goats) consume grass, they are the source of B12. If animals cleaned grass prior to eating, they wouldn’t receive B12 from their diet. Fortunately, they do not. Furthermore, herbivores or grass-eating animals produce vitamin B12 within their stomachs.

This is why vitamin B12 is found naturally in animal-based foods. A good source of B12 is:

Chicken, red meat eggs, fish and red meat.

Also, dairy-based productssuch as cheese, milk, paneer, yoghurt are an additional way of obtaining vitamin B12.

Plant Food B12 sources:

I’ve already mentioned that plants do not produce vitamin B12. However, fermented plant foods could contain vitamin B12 since the process of fermentation is based on microorganisms such as yeast or bacteria.

Consuming foods like sauerkraut, pickles, kimchi, sauerkraut Idli, tempeh and dosa, and tempeh can give you some B12. However, you must be sure that these food items aren’t processed, since the process can kill good bacteria.

Certain algae and seaweeds such Chlorella. Chlorella are also regarded as an important source of B12.

NOTE: From all the research I have found, plant food is considered to be an unreliable sources of B12. This is a hotly debated subject and requires more research to establish the truth.

What is the cause of vitamin B12 deficiency

It is obvious that you could be susceptible to developing an vitamin B12 deficiency if your do not consume sufficient B12 food items. Because B12 is most often found in animal food (meat eggs, dairy, and fish) vegans are particularly susceptible to B12 deficiency.

It’s not so easy…

B 12deficiency is also seen in those who consume dairy products and meat foods. B12 molecule is huge in size and absorption is complicated and requires a number of steps. If one of these steps goes wrong, the vitamin will not be absorbed.

Below is the way B12 can be taken up…

First step: Normally, when you consume foods that contain vitamin B12, your stomach acids help release vitamin B12 into the food

Second step:B12 later combines an extra protein known as intrinsic factor (made by cells within stomach).

Third step: Vitamin B12 and intrinsic factor are then taken up by the body into the gut, at the bottom of the small intestine.

It is also possible to be prone to vitamin B12 deficiency if you suffer from:

  • Acidity in the stomach is low or absent (this could influence B12’s release in food)
  • Atrophic gastritis occurs when the stomach lining is thinned
  • Surgery that removes a part of your stomach, or your small in the intestine, and weight reduction surgery
  • Long-term use of drugs that lower stomach acid (lansoprazole and Omeprazole)
  • Pernicious anaemia (your body’s immune system destroys the cells that produce intrinsic factor)
  • Intestinal issues like Crohn’s disease or celiac disease or any other conditions that hinder the body’s digestive system to process food.
  • Infections with tapeworms
  • Excessive alcohol intake
  • Exposition to nitrous oxide (laughing gas)

How can you tell if you have B12 Deficiency?

B12 deficiency is far more prevalent than was previously thought. Statistics from this Framingham study suggest that close to 40% from the United States population may be deficient in vitamin B12. The rates could be more prevalent across Africa, India, and Central and South America.

Contrary to others water-soluble vitaminsunlike other water-soluble vitamins (C as well as B vitamins) B12 isn’t released from the body in a rapid manner when we drink urine. It’s stored in the kidneys, liver as well as other tissues in your body. Therefore, those who quit eating animal products can wait for years before displaying any indications or symptoms of the B12 deficiency.

**Water soluble vitamin dissolve in water. Vitamins that are water-soluble (such like vitamin C or B complex) are transported into the tissues of the body, however they are not stored inside the body. They must therefore be taken daily. However, vitamin B12 is a different case and is stored for a long time.

What is an unintentionally low B12 level?

B12 levels are measured using various units in different countries. It can be confusing for people and make some believe their levels are low. In addition, the normal range can differ from countries to countries. Therefore, it is recommended to talk with your doctorto determine whether your blood sugar levels are too low or not.

As a general rule of thumb, B12 levels should be at or above 191ng/L. (191ng/L is equal to 550 pg/mL or approximately 430 permol/L.) In case your B12 levels are less than this, you’re not getting enough vitamin. B12 levels are lower than this, then you definitely have a deficiency in B12.
