When we talk about nutrition, most people think of proteins, carbohydrates, and fats. But long-term health depends just as much on micronutrients—vitamins and minerals required in small amounts that regulate nearly every system in the body.
Micronutrient deficiencies are increasingly seen in both urban and rural populations, even among individuals who eat regular meals. This is often due to limited dietary variety, lifestyle factors, and absorption issues, rather than lack of food alone.
What Are Micronutrients?
Micronutrients are essential nutrients required in small quantities to support:
- Immune function
- Energy metabolism
- Brain and nerve function
- Bone and blood health
- Hormone and enzyme activity
They are broadly classified into:
- Vitamins
- Minerals

Vitamins vs Minerals
| Vitamins | Minerals |
|---|---|
| Organic compounds | Inorganic elements |
| Derived from plant and animal foods | Derived from soil and water |
| Easily affected by heat and light | More stable during cooking |
| Required in small amounts | Some required in larger amounts |
Both are essential, and deficiencies can lead to progressive health complications if left unaddressed.
Water-Soluble vs Fat-Soluble Vitamins
Water-Soluble Vitamins
- Vitamin B-complex and Vitamin C
- Not stored in the body
- Excess amounts are excreted in urine
- Require regular intake
Fat-Soluble Vitamins
- Vitamins A, D, E, and K
- Stored in fat tissue and the liver
- Best absorbed with dietary fat
- Excess intake may lead to toxicity if unsupervised
Understanding this distinction is important for both diet planning and supplementation.
Key Vitamins and Their Clinical Importance
Vitamin A
Functions
- Supports vision, particularly night vision
- Strengthens immune defense
- Maintains skin and epithelial health
Food Sources
Carrots, sweet potatoes, mangoes, spinach, eggs, liver
Deficiency
- Night blindness
- Dry skin
- Recurrent infections
Vitamin D
Despite adequate sunlight in equatorial regions, Vitamin D deficiency is still observed—particularly in individuals with limited sun exposure or increased physiological demands.
Functions
- Calcium absorption and bone strength
- Muscle function
- Immune modulation
Sources
Sunlight exposure, fatty fish, egg yolks, fortified dairy products
Deficiency
- Bone pain or weakness
- Osteomalacia or osteoporosis risk
Vitamin E
Functions
- Antioxidant protection
- Cardiovascular support
- Skin and cellular integrity
Sources
Nuts, seeds, vegetable oils, avocados, green leafy vegetables
Deficiency (Uncommon)
- Muscle weakness
- Neurological symptoms
- Impaired immunity
Vitamin K
Functions
- Blood clotting regulation
- Bone metabolism
Sources
Leafy greens, broccoli, dairy products, liver
Deficiency
- Easy bruising or bleeding
- Reduced bone density
The Vitamin B-Complex
B-vitamins play a central role in energy production, neurological health, and red blood cell formation.
They include:
- B1 (Thiamine)
- B2 (Riboflavin)
- B3 (Niacin)
- B5
- B6
- B7 (Biotin)
- B9 (Folate)
- B12
Deficiency Symptoms
- Fatigue and weakness
- Numbness or tingling
- Cognitive changes
- Anemia
- Mood disturbances
Vitamin C
Functions
- Immune system support
- Wound healing
- Collagen synthesis
- Enhanced iron absorption
Sources
Citrus fruits, strawberries, kiwi, tomatoes, broccoli, bell peppers
Deficiency
- Bleeding gums
- Delayed wound healing
- Increased susceptibility to infections
Why Micronutrient Deficiencies Occur
Deficiencies may result from:
- Limited dietary diversity
- Increased requirements (pregnancy, illness, stress)
- Malabsorption disorders
- Prolonged medication use
Early identification is essential to prevent long-term complications.
When to Seek Medical Advice
Consider evaluation if you experience:
- Persistent fatigue
- Frequent infections
- Bone or muscle pain
- Neurological symptoms
- Hair or skin changes
