Micronutrients are comprising of essential vitamins and minerals which are very important for the proper functioning of from inside and outside. However, nutrients deficiency are very common phenomena across the globe. As an individual we often ignore the mild deficiency syndrome unless and until it becomes severe health issues. 

Some of the important minerals essential for human body are Sodium, Magnesium, Phosphorus, Sulphur, Chloride, Potassium, Calcium, Fluoride, Manganese, Iron, Copper, Zinc, Selenium, Iodine. Based on the requirements of the body these minerals have been categorised in macro and trace minerals.

Types of Minerals

  • Macro Minerals: Sodium, Magnesium, Phosphorus, Sulphur, Chloride, Potassium, Calcium
  • Trace Minerals: Fluoride, Manganese, Iron, Copper, Zinc, Selenium, Iodine

What is Mineral Deficiency?

Mineral deficiency is the health condition in which the body obtain recommended daily intake or inability of body to absorb right amount of minerals. The prior condition is termed as primary while the later known known as secondary deficiency. This deficiency can cause improper functioning of cells, tissues and organs in short term, but it may poses serious health issues in long term. 

Types of Mineral Deficiency

  • Primary: Caused by long term inadequate intake of nutrients
  • Secondary: Caused by malabsorption

The primary deficiency can be caused intake of mineral deficient diets for very long time while the major cause for secondary deficiencies are underlying health condition. The causes, symptoms, its associated health risk and diseases, their remedies and daily recommended intake for essential minerals are illustrated below.

Minerals Deficiency: Causes, Symptoms, Health Risks, Remedies and Adequate Intakes (1, 2, 3)

  • Adequate Intake (>19 Yrs.): 4700 mg


  • Causes: The major cause of calcium deficiency can be caused due to calcium deficient diet, hormonal fluctuations, other micronutrient deficiency, enhanced demand in case of pregnancy and breastfeeding. In addition to these malabsorption and utilisation due to pre-existing health disorders. 
  • Symptoms: Numbness, tingling, muscle spasm, muscle cramp, confusion, memory loss, depression hallucination, bone loss, tooth decay.
  • Associated Health Risk: Hypocalcemia, Osteoporosis, Heart dysfunction, Hormonal imbalance, Nerve transmission loss. 
  • Remedies: The rich source of calcium is milk and its product. Calcium deficiency can be prevented by inclusion of calcium rich food items like milk, cheese, leafy veggies, soybeans, tofu, sardines, pilchards in our diet. However, in case of severe deficiency medical supplements might yield better results.
  • Adequate Intake (>19 Yrs.): 2000-2500 mg


  • Causes: Fluoride deficiency is caused by insufficient consumption or improper utilisation of fluoride. Since it’s a trace mineral it can be affected by the excessive discharge from the body or malabsorption due to presence of health condition.
  • Symptoms:  Weak bones, fracture, tooth decay.
  • Associated Health Risk: Cavities, Osteoporosis, Reduces bone density.
  • Remedies: Fluoride rich food items like, fruit juice, crab, water, shellfish, grapes can he help in addressing mild deficiency while for severe case of deficiency medical supplements will be required. Fluoride rich water is the commonly used solution for this deficiency.
  • Adequate Intake (>19 Yrs.): 3-4 mg


  • Causes: The manganese deficiency can be caused by the inadequacy of manganese in our diet and malabsorption of manganese due to pre-existing gastrointestinal disorders, epilepsy, diabetes, osteoporosis. However, clinical evidences have different opinion on manganese supplements through manganese rich diet.
  • Symptoms:  Fatigue, weakness, irritability, delayed and impaired growth, menstrual problems, poor bone growth, skeletal defects, abnormal metabolism, memory loss.
  • Associated Health Risk: Bone health, osteoporosis, dermatitis, schizophrenia, disrupts the production of collagen, GI diseases.
  • Remedies: Manganese rich diet is very helpful for mild deficiency. Some of the manganese rich food items are pineapple, peanuts, whole grains, clams, oysters, mussels, nuts, soybeans, legumes, rice, leafy vegetables, coffee, tea, black pepper.  However, in case of severe deficiency medical supplements might be required.
  • Adequate Intake (>19 Yrs.): 1.8-2.8 mg


  • Causes: Iron deficiency is caused by the inadequate intake of iron in our daily food item. However, it can be caused by heavy bleeding during menstruation, pregnancy, increased utilisation during lactation, internal bleeding, malabsorption due to present health condition like gastrointestinal disorders.
  • Symptoms:  Headaches, nausea, weakness, fatigue, dizziness, irregular heartbeat, bleeding, tingling, numbness, pale skins.
  • Associated Health Risk: Anaemia, Heart disease, complications during pregnancy and childbearing, child with low birth weight, delayed growth, prone to infections.
  • Remedies: Preventive actions like inclusion of iron rich food like oyster, white beans, spinach, lentils, tofu, cashews, whole grain in our diet can minimise the impact of iron deficiency. However, in severe deficiency its advisable for taking supplements as suggested by medical experts.
  • Adequate Intake (>19 Yrs.): 8-18 mg


  • Causes: The copper deficiency can be caused due to inadequate intake and utilisation of copper. However, the most common cause of these deficiency is GI surgery which affects the absorption of copper. Menkes is the genetic disorder of copper deficiency.
  • Symptoms:  Fatigue, pale skin, poor growth, muscle soreness, always feeling cold.
  • Associated Health Risk: Menkes, enzootic ataxia, hyper flexibility of the joints and fragility of the veins in newborns, increased risk of atherosclerosis, affects bone marrow.

  • Symptoms:  Weakness, tiredness, fatigue, unexpected weight gain, dry skin, hair loss, feeling cold, swollen neck.
  • Associated Health Risk: Goitre, endemic goitre, cretinism, impaired growth and brain development, impaired metabolism, complications during pregnancy, heavy or irregular periods.
  • Remedies: Iodine deficiency syndrome can be prevented by consuming iodine rich foot item like seaweed, shrimp, fish, Cod, dairy products, whole grain. The dietary supplements are good for mild cases while medical supplements will be required for severe deficiency.
  • Adequate Intake (>19 Yrs.): 150 mcg


The importance of micronutrient is often overlooked in our society. We usually focusing in belly filling rather than offering healthy diet to our cell. Apart from staple diet we need these essential micronutrients in order to remain healthy. Micronutrient rich diet should be preferred and if not available than their supplements should be taken to make the right balance. However, fortified food items can be the substitute of stable diet which are poor in micronutrients. “Stay Healthy Stay Happy”.
