Vitamin B12 Benefits for Women – Blood Cells

Vitamin B12 benefits for women and men are vital to the body. It is important for making red blood cells, nerve tissue health and brain function. Like all other B vitamins, vitamin B12 is a water-soluble vitamin.

This shows it can dissolve in water and pass through the circulatory system. Up to four years’ worth of vitamin B12 can be stored by the body, and any extra or undesired amounts can be excreted in the urine.

The largest and most chemically complex vitamin is vitamin B12. Naturally, it can be found in animal products like meat, seafood, and eggs. It can be produced by manufacturers by bacterial fermentation synthesis.

It is suggested that pregnant and nursing women maintain a healthy level of this vitamin. It is suggested that pregnant and nursing women maintain a healthy level of this vitamin.

When vitamin B12 levels in the body are not high enough to meet the needs of the body, a deficit or insufficiency can develop. Several symptoms may result from this, and if left untreated, it may possibly worsen into irreversible neurological problems.


Benefits of Vitamin B12

Your body need vitamin B12 to make proteins like hormones and digestive enzymes. Moreover, it lowers the chance of macular degeneration. 34% of women who began taking vitamin B12 and B6 after the age of 40 had a reduced chance of developing age-related macular degeneration.

Prenatal health is vital for preventing birth abnormalities. In pregnant women, vitamin B12 reduces the incidence of miscarriage, and low birthweight. Furthermore, pregnant women need enough vitamin B12 for the healthy development of their baby’s nervous system, and a lack of this nutrient during pregnancy can cause irreversible brain damage to the unborn child.

Vitamin B12 is important for healthy neurons in the brain. It improves memory loss. Taking vitamin B12 supplements, reduces homocysteine levels in the blood which slows the rate of cognitive and clinical decline in older persons with early-stage dementia.

Vitamin B12 is necessary for the growth, myelination, and function of the central nervous system, including the creation of healthy red blood cells and the synthesis of DNA. The benefits of this essential vitamin are:

  • Proper brain and nerve system functioning
  • Mental performance
  • Prevention of anemia through red blood cell production
  • Assisting with DNA creation and control
  • Potential prevention of heart defects
  • Preventing macular degeneration in the eyes
  • Essential to energy generation

Natural Source of Vitamin B12

The federal government’s 2020-2025 Dietary Guidelines for Americans, emphasized, the importance of getting most of one’s daily calories from food. This is because foods supply a wide variety of nutrients and other components that are beneficial to our health.

Fortified foods and dietary supplements can be helpful for meeting nutrient demands throughout times of life when it is difficult to do so naturally, such as pregnancy.

Vitamin B12 is produced by bacteria and is only found naturally in animal products, according to the source. On the other hand, synthetic variants are simple to obtain and find in many processed meals such as packaged cereals.

Foods rich in vitamin B12 includes, Fish, shellfish, liver, red meat, eggs, poultry, dairies such as milk, cheese and yogurt, fortified nutritional yeast and cereals, soy and rice milk,


Vitamin B12 Deficiency

In reality, measuring vitamin B12 levels in the blood is not the most accurate method for determining vitamin B12 deficiency. As some individuals with a deficit can have normal B12 levels in their blood.

Many individuals do not recognize vitamin B12 insufficiency symptoms because they attribute them to aging. Those with imbalanced vitamin levels may experience weariness, dizziness, pale complexion, red tongue, bleeding gums, weight loss, memory loss, diarrhea or constipation, and depression.

Methylmalonic acid, a byproduct of protein metabolism, and homocysteine levels in the blood are more accurate indicators of vitamin B12 efficiency.

A deficiency in vitamin B12 is believed to affect up to 15% of the general population. These values increase in the absence of vitamin B12.

Possible Causes of Vitamin B12 Deficiency

  1. Not consuming animal products. Vitamin B12 is only found naturally in animal products, thus vegetarians and those who avoid these foods may be at risk for a deficiency. Studies indicate that vegans have low vitamin B levels in their blood. Therefore, vegetarians should consume B12-enriched foods or take a B12 supplement.
  2. Pernicious anemia. An inflammatory illness that assaults and potentially destroys gastrointestinal cells, preventing the presence of intrinsic factor, which is required for vitamin B12 absorption. Unfortunately, because there is no inherent element to facilitate its absorption, taking a megadose of B12 will not help.
  3. Gastrointestinal operations. Surgical procedures that impact the stomach, where intrinsic factor is produced and vitamin B12 is absorbed, are contraindicated. It may increase the chances of deficiency.

Vitamin B12 Supplements

Dietary Reference Intakes (DRIs) provide guidelines for the consumption of vitamin B12 and other nutrients. Formulated by the National Academies of Sciences, Engineering, and Medicine’s Food and Nutrition Board (FNB).

(DRI) refers to a specific set of specified levels that are used in the process of meal planning and nutritional assessment. These standards, may change with age and sex.

The FNB’s key requirement for adults was the amount required to maintain a good cytogenetic state and vitamin B12 blood levels. The FNB produced an AI for infants aged 0 to 12 months that corresponds to the mean vitamin B12 intake of breastfed infants who are healthy.

  • Birth – 6 months, 0.4 mcg male and 0.4mcg female
  • 7-12 months, 0.5 mcg male and 0.5 mcg female
  • 1-3 years, 0.9 mcg male and 0.9 mcg female
  • 4-8 years, 1.2 mcg male and 1.2 mcg female
  • 9-13 years, 1.8 mcg male and 1.8 mcg female
  • 14-18 years, 2.4 mcg male and 2.4 mcg female
  • 19+ years, 2.4 mcg male and 2.4 mcg female

Vitamin B12 is typically sold as pills, as well as sublingual and quick-dissolving tablets, and sprays. It is unclear whether some of the alternative formulations give a biological advantage, as the majority of B12 from these products is expected to be absorbed by the gut after being ingested.

Keep in mind that some non-pill formulations may use sugar substitutes like mannitol and sorbitol to enhance taste. Large dose may increase the likelihood of experiencing gas, bloating, and diarrhea.


Vitamin B12 is a water-soluble nutrient that can be found in a variety of food sources, as well as fortified foods, dietary supplements, and prescription drugs. Vitamin B12 is necessary for the growth, myelination, and function of the central nervous system, as well as red blood cell creation and DNA synthesis.

Prenatal wellness is essential to preventing birth defects. Vitamin B12 lowers the incidence of miscarriage and low birthweight in pregnant women. In addition, pregnant women require adequate vitamin B12 for the proper growth of their baby’s neurological system, and a deficiency in this mineral during pregnancy can result in irreversible brain damage in the unborn child.

Since the liver can store vitamin B12 for usage when supplies are low, it is safe to consume reasonable amounts of this nutrient even in times of plenty. It takes time for people to become aware of a B12 shortage in their diet because B12 stores can persist for several years.

Vitamin B12 deficiency may affect up to 15% of the population. These readings increase when vitamin B12 is absent.

Vitamin B12 is found in abundance in a variety of foods, such seafood, low-fat beef, fortified cereal, fortified soymilk, fortified tofu, low-fat dairies, and eggs.

Adults should take 2.4 milligrams of vitamin B-12 day, however larger amounts have been reported to be safe.
