Distinguishing Symptoms of Vitamin B12 and Folate Deficiencies

Vitamin B12 and folate deficiencies can both result in megaloblastic anemia, but they exhibit distinct symptoms due to their varying roles in the body. Here’s how they differ:

Vitamin B12 Deficiency Symptoms:

• Neurological Issues: Vitamin B12 deficiency often leads to neurological problems such as numbness and tingling in the extremities, difficulty walking, memory issues, and cognitive disturbances.
• Psychiatric Symptoms: It may also cause mood changes, including depression, irritability, and mood swings.
• Oral Symptoms: Common signs include inflammation of the tongue (glossitis) and mouth ulcers.
• General Anemia Symptoms: Fatigue, weakness, and pallor are also prevalent.

Folate Deficiency Symptoms:

• Gastrointestinal Issues: Folate deficiency typically presents with gastrointestinal symptoms like diarrhea, reduced appetite, and weight loss.
• Oral Symptoms: It can also cause mouth sores and a swollen tongue, similar to vitamin B12 deficiency.
• General Anemia Symptoms: Fatigue, weakness, and pallor are common.
• Neural Tube Defects: In pregnant women, folate deficiency poses a risk of neural tube defects in the developing fetus.

Although both deficiencies can cause fatigue and mouth sores, the presence of neurological symptoms is a distinguishing feature of vitamin B12 deficiency. Accurate diagnosis and treatment are crucial to manage these deficiencies and avoid long-term complications.
Distinguishing Symptoms of Vitamin B12 and Folate Deficiencies

Folate deficiency anemia

Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It is also added to foods and sold as a supplement in the form of folic acid. Folate is found in citrus fruits and juices as well as leafy greens, legumes and fortified carbohydrates. Having adequate folate in human diet is essential for preventing deficiency-related anemia.

A folate deficiency is rare because it is found in a wide range of foods. Signs of deficiency can include: megaloblastic anemia; weakness, fatigue; irregular heartbeat; shortness of breath; difficulty concentrating; hair loss; pale skin; mouth sores.

Folate-deficiency anemia is the lack of folic acid in the blood. Folic acid is a B vitamin that helps body make red blood cells. Red blood cells carry oxygen around the body using a substance called hemoglobin. Anemia is the general term for having either fewer red blood cells than normal or having an abnormally low amount of hemoglobin in each red blood cell.

Low levels of folic acid can cause megaloblastic anemia. Megaloblastic anemia characterized by the formation of abnormally large red blood cells with defects in DNA synthesis.

There are fewer of these cells. They are also oval-shaped, not round. Sometimes these red blood cells do not live as long as normal red blood cells.

Folate deficiency can occur due to dietary deficiency, malabsorption, pregnancy, malignancy, blood disorders, inflammation, or drugs. Common symptoms of anemia include fatigue, dyspnoea, palpitations, headaches, tinnitus or anorexia.

Vitamin B9

Vitamin B9 is water soluble vitamin. Its synthetic form folic acid (FA) used in fortification and supplements, are critical to human health due to their role in one-carbon transfer reactions required for biological methylation and nucleotide biosynthesis.

Folate is the natural form of vitamin B9. The name folate comes from folium, which is the Latin word for leaves, because folates were first isolated from spinach. Folate is critical to human health as it mediates one carbon transfer reactions important to processes such as nucleotide biosynthesis, the methionine cycle and biological methylation.

Folate is added to foods and sold as a supplement in the form of folic acid; this form is actually better absorbed than that from food sources.

Vitamin B9 is important as it helps the body as a coenzyme to
• utilize amino acids, the building blocks of proteins
• playing an essential role in deoxyribonucleic acid (DNA) synthesis,
• maintenance of DNA integrity and DNA repair
• form blood cells in the bone marrow and for healthy cell growth and function
• ensure rapid cell growth in infancy, adolescence, and pregnancy
• control (together with vitamin B6 and vitamin B12) blood levels of the amino acid homocysteine, associated with certain chronic conditions such as heart disease.

The chemical formula of folic acid is C19H19N7O6. The core of the molecule consists of heterocyclic pterin structure, with a methyl group in the sixth position bound to para-aminobenzoic and glutamic acids so that folic acid presents pteroylglutamic acid.

Folate deficiency can result from inadequate intake, defective absorption, abnormal metabolism or increased requirements. This type of deficiency is no longer a problem in many countries that fortify foods such as cereal and pasta with folic acid.

Early symptoms of folate deficiency are non-specific and may include tiredness, irritability and loss of appetite. Severe folate deficiency leads to megaloblastic anemia, a condition in which the bone marrow produces oversized immature red blood cells.

Folate is found mainly in dark green leafy vegetables, beans, peas and nuts. Fruits rich in folate include oranges, lemons, bananas, melons and strawberries. Men and women ages 19 years and older should aim for 400 mcg DFE. Pregnant and lactating women require 600 mcg DFE and 500 mcg DFE, respectively.

Food sources of vitamin B9

Folate is the natural form of vitamin B9 and it is important in red blood cell formation and for healthy cell growth and function. The nutrient is crucial during early pregnancy to reduce the risk of birth defects of the brain and spine. The vitamin is water-soluble and naturally found in many foods. The synthetic form of folate is folic acid.

Folate plays an important role in protein metabolism and helps to form DNA and RNA. It plays a key role in breaking down homocysteine, an amino acid that can exert harmful effects in the body if it is present in high amounts. It’s also necessary for the production of healthy red blood cells and is critical during periods of rapid growth, such as during pregnancy and fetal development.

Folate is found mainly in dark green leafy vegetables, beans, peas and nuts. Fruits rich in folate include oranges, lemons, bananas, melons and strawberries.

One cup (177 grams) of cooked kidney beans contains 131 mcg of folate, or about 33% of the Daily Value (DV). Meanwhile, one cup (198 grams) of cooked lentils contains 358 mcg of folate, which is 90% of the DV.

In January 1998, the U.S. Food and Drug Administration required food manufacturers to add folic acid to foods commonly eaten, including breads, cereals, pasta, rice, and other grain products, to reduce the risk of neural tube defects.

A diet lacking foods rich in folate or folic acid can lead to a folate deficiency. Folate-deficiency anemia is the lack of folic acid in the blood. Folate deficiency can also occur in people who have conditions, such as celiac disease, that prevent the small intestine from absorbing nutrients from foods. Low levels of folic acid can cause megaloblastic anemia. With this condition, red blood cells are larger than normal.

Men and women ages 19 years and older should aim for 400 mcg DFE. The CDC recommends that all women get at least 400mcg of folate a day, whether or not they plan on becoming pregnant. Pregnant and lactating women require 600 mcg DFE and 500 mcg DFE, respectively.

Main roles of folate in human body

Orange juice may be considered a good source of natural folate in respect to content and stability during storage. Folate is one of the B group vitamins, naturally found in food, that plays an important role in cell division and the synthesis of amino acids and nucleic acids like DNA.

On average 150 mL of orange juice provide about 32.3 ug of folate. Other good sources of folate include:
*Breakfast cereals with fortification of folic acid
*Wholegrain or brown bread, pasta or brown rice
*Fruit and veges: Spinach, peas, asparagus, broccoli, brussel sprouts,
*Tinned baked beans
*Chick peas

Roles of folate in human body:
*Helps normal psychological function
*Helps the immune system to work normally
*Has a role in the process of cell division
*Helps reduce tiredness and fatigue

Folates play a key role in one‐carbon metabolism, that is, key reactions in the synthesis of proteins with the amino acids methionine, histidine, serine, and glycine, but also DNA with purines and thymidilate or vitamin B5.

It is well established that folates are beneficial in the prevention of neural tube defects and cardiovascular and neurodegenerative diseases.
