signs and symptoms of vitamin deficiency

Vitamin deficiency occurs only one lacks the necessary nutrients that are supposed to feed your body with the required amount of vitamins.

These lack of well-balanced vitamin-based foods are the causes of some number of diseases manifesting its signs and symptoms in our body.

What Is Vitamin Deficiency?.

Vitamin deficiency is the condition of a long-term lack of a vitamin.

When it’s not caused by not taking enough vitamin, it can then be classified as a primary deficiency, whereas when due to an underlying disorder such as malabsorption, it is called a secondary deficiency.

An underlying disorder may be metabolic – as in a genetic defect for converting tryptophan to niacin – or from lifestyle choices that increase vitamin needs, such as smoking, accessive alcoholic consumption.

Vitamins And Their Functions:

Here are the lists of vitamins and their functions, here you will see why we all need ideal healthy foods that guarantee our Daily Required Intake (DRI)

Vitamin A:

Vitamin A is particularly important for healthy skin and eyes.

Vitamin A deficiency is the world’s leading cause of preventable blindness in children and increases the risk of disease and death. It’s a serious problem in more than half of all countries, though it mainly affects poorer regions.

In pregnant women, this vitamin deficiency can cause night blindness, and increase the risk of maternal mortality.

Vitamin C:

Vitamin C (or ascorbic acid) is vital because it’s needed to make collagen. Without it, collagen can’t be replaced and the body’s tissues will break down, leading to the signs and symptoms of scurvy.

These include muscle and joint pain, fatigue, red dots on the skin, and bleeding and swelling of the gums.

Vitamin C is also an antioxidant and regenerates other molecules such as vitamin E, so they can be used as antioxidants multiple times.

If you have to take a lot of vitamin C from supplements to reach the safe upper limit and at very high levels, mind you, over long periods of time it may lead to kidney stones risk.

Thiamin (B1):

Thiamin (vitamin B1) is important for energy metabolism, particularly carbohydrate metabolism. It’s also key for muscle contractions and the conduction of nerve signals.

Vitamin (B2):

Riboflavin, Vitamin B2 is what helps convert food into energy. It’s needed for healthy skin, hair, blood, and brain.

Niacin (B3):

Niacin (vitamin B3) is the general name for both nicotinic acid and nicotinamide/niacinamide.

Niacin is important for helping the body to release energy from the food sources we eat. It ensures the proper functioning of our nervous system and liver.

Heads Up:

Taking too much niacin is only possible from supplements, not food. If taken for too long at high doses, supplements can cause liver damage.

The prolonged uses of medication have been discovered to be the source of pathogenic bacteria in most cases.

Pantothenic Acid (B5):

Vitamin B5 helps convert food into energy and also Helps make lipids (fats), neurotransmitters, steroid hormones, and hemoglobin.

Vitamin B6:

Aids in lowering homocysteine levels and may reduce the risk of heart disease.  and helps to convert tryptophan to niacin and serotonin, a neurotransmitter that plays key roles in sleep, appetite, and moods. Helps make red blood cells Influences cognitive abilities and immune function.

Calciferol (Vitamin D):

Helps maintain normal blood levels of calcium and phosphorus, which strengthen bones. Helps form teeth and bones.

Folic Acid (B9):

Vital for new cell creation…  helps prevent brain and spine birth defects when taken early in pregnancy; should be taken regularly by all women of child-bearing age since women may not know they are pregnant in the first weeks of pregnancy.

Can lower levels of homocysteine and may reduce heart disease risk May reduce the risk for colon cancer. Offsets breast cancer risk among women who consume alcohol.

Alph-Tocopherol (Vitamin E):

Acts as an antioxidant, neutralizing unstable molecule that can damage cells. Protects vitamin A and certain lipids from damage. Diets rich in vitamin E may help prevent Alzheimer’s disease.

Vitamin K:

Vitamin K has several important functions, such as blood clotting, which means it helps wounds heal properly. It also works with vitamin D to regulate calcium in the body, so plays a role in bone health.

Vitamin B12:

Aids in lowering homocysteine levels and may lower the risk of heart disease. Assists in making new cells and breaking down some fatty acids and amino acids. Protects nerve cells and encourages their normal growth Helps make red blood cells and DNA.

Biotin B7:

Biotin is also known as Vitamin B7, I required for the metabolism of all three macronutrients. Only small amounts are required in the diet as our gut microbiota can produce biotin for the body to use.

Common Signs And Symptoms Of Vitamin Deficiency:

Brittle nails and hair: 

Brittle hair and nails are one of the most glaring symptoms of Biotin deficiency in the body. 

Other symptoms of Biotin deficiency include muscle pain, cramps, chronic fatigue, tingling in the hands and feet as well as thinning and splitting hair.


Anti-seizure medications and prolonged use of some antibiotics are some factors that are associated with high risks of biotin deficiency in the body.  signs and symptoms of vitamin deficiency

Riboflavin (Vitamine B2):

Riboflavin deficiency causes painful red tongue with a sore throat, chapped and cracked lips, and inflammation at the corners of the mouth (angular cheilitis). Eyes can be itchy, watery, bloodshot and sensitive to light.

Riboflavin deficiency also causes anemia with red blood cells that are normal in size and hemoglobin content but reduced in number.

This is distinct from anemia caused by the deficiency of folic acid or vitamin B12.

Bleeding Gum:

Some of the time a rough tooth brushing can be the root of bleeding gums, but in most cases, deficiency in vitamin C carries the blame.

Vitamin C plays important roles in wound healing, immunity and even acts as an antioxidant, helping prevent cell damage.

The human body does not make vitamin C on its own, which means the only way to maintain adequate levels of it is through the diet.

Vitamin A deficiency: Common signs and symptoms of vitamin deficiency

Is the leading cause of preventable blindness in children, as valuable as it’s that even a mild deficiency can impair immune function, thereby reducing resistance to diseaseNight blindness is an early sign of vitamin A deficiency.

Other Common signs And Symptoms Of Vitamin Deficiency:

Dandruff and scaly patches:

Dandruff and Seborrheic Dermatitis are skin conditions that are both linked to the oil-producing areas of the body, both of which involve flaking and itchy skin.
While Seborrheic Dermatitis generally affects the armpits, groin, face and upper chest, Dandruff is restricted to the scalp. While both these conditions are caused by a variety of factors, Vitamin deficiency is one of the major causes of these skin disorders.

Lower levels of Riboflavin (Vitamin B2), Niacin (Vitamin B3), Pyridoxine (Vitamin B6) and Zinc have been intrinsically linked to these disorders of the skin.

Vitamin D:

The deficiency may cause the softening of bone, called rickets, may affect the nervous system and may cause weakness of the proximal muscles.

Vitamin B12:

Deficiency can lead to pernicious anemia, megaloblastic anemia, subacute combined degeneration of spinal cord, and methylmalonic acidemia, among other conditions.

Hair Loss:

Hair loss is a very common symptom of vitamin deficiency. In fact, up to 50% of men and women report suffering from hair loss by the time they reach 50 years of age.

Niacin (vitamin B3): This vitamin is necessary for keeping hair healthy. Alopecia, a condition in which hair falls out in small patches, is one possible symptom of niacin deficiency. Biotin is another B vitamin that, when deficient, may be linked to hair loss.

Pantothenic acid:

The Vitamine B5 deficiency may be extremely rare, Nevertheless, its symptoms include irritability, fatigue, and apathy.

Vitamin B6:

B6 deficiency is uncommon, although it may be observed in certain conditions, such as end-stage kidney diseases or malabsorption syndromes, such as celiac disease, Crohn disease or ulcerative colitis.

Signs and symptoms include microcytic anemia, electroencephalographic abnormalities, dermatitis, depression and confusion.

Vitamin E:

Vitamin E deficiency is rare in humans, although it may develop in people with impaired fat absorption or metabolism, the fragility of red blood cells (hemolysis) is seeN.

Where Vitamin deficiency is more prolonged, neuromuscular dysfunction involving the spinal cord and retina may occur resulting in loss of reflexes, impaired balance and coordination, muscle weakness, and visual disturbances.

Vitamin K:

The deficiencies in newborns are associated with vitamin K deficiency bleeding or VKDB (also known as hemorrhagic disease of the newborn). This can cause excessive bleeding and bruising and, in severe cases, can lead to fatal bleeding into the brain.

Although it’s rare in adult, adults can be at an increased risk of vitamin K deficiency and the associated symptoms if they:

  • take anticoagulants that prevent blood clots but inhibit vitamin K activation.
  • take antibiotics that interfere with vitamin K production and absorption
  • do not get enough vitamin K from the foods they eat
    take extremely high doses of vitamin A or E.

Bottom Line: 

People who take diets that provide too little vitamins experience the appearance of these symptoms, and some are more common than others.

It’s advisable to increase your intake of foods rich in the appropriate vitamins (minerals inclusive) to help balance your hormones and steer you clear off the risks of the common signs and symptoms of vitamin deficiencies.
