B12 vitamin It’s essential for optimal health, but our bodies can’t make it, and a lack of the nutrient can affect our DNA, according to one expert.
Deficiency can cause changes in the skin, mouth, and even hair. The nutrient is a key player in the formation of red blood cells. It also plays a vital role in the function and development of the brain and nerve cells.
As b12 vitamin helps produce red blood cells, having enough is essential for hair growth and overall health, the mirror informs.
We’ve taken a look at what happens to our hair if we don’t have enough of it.
Hair loss
A lack of the nutrient can actually affect our DNA, says the health site Medical News Today.
DNA is the information within each cell that carries the instructions for the growth, development, and function of all cells, tissues, and organs in the body.
“When the cell reproduces, it must first make a copy of its DNA. Hair growth depends on proper DNA synthesis and vitamin B12, among other nutrients,” the site says.
When it is missing a lot, this process stops, which could lead to hair loss. This can also occur through the reduction of red blood cells that carry oxygen to the hair follicles.
Vitamin B12 is essential for making red blood cells.
“When vitamin B12 levels are low, hair follicles may not be able to grow new hair as efficiently, resulting in hair loss,” says Indian health site Skin Kraft Laboratories.
Being low in the nutrient can also cause symptoms of anemia, which is associated with low iron levels, thinning hair and hair loss.
grey hair
If you are young and have noticed your hair turning grey, it could be due to a vitamin B12 deficiency.
In fact, a lack of sufficient vitamin B12 is one of the most common causes of premature graying of hair.
“Premature graying of gray hair can be reversed with vitamin B12 supplementation only if the cause is vitamin B12 deficiency,” says Medicine.net.
The site added: “If you are going gray due to other factors, such as genetics, zinc deficiency, or medication, then your gray hair cannot be reversed.”
Vitamin B12 supplements are available, but it is also found naturally in fish, meat, poultry, eggs, milk, and other dairy products.
Some of the best sources of vitamin B12 can be found in clams and beef liver.
Several breakfast cereals, nutritional yeasts, and other food products are also fortified with this nutrient.
