(Updated Guide for 2025)

 

Our body needs a balanced supply of vitamins and minerals to function optimally. However, a hectic lifestyle, poor diet, stress, or certain health issues can lead to vitamin deficiencies, which—if left unaddressed—may result in serious problems over time.

But how does your body alert you to a deficiency? Which symptoms are linked to which vitamins?

Let’s dive into the details:

 

 

 

1.     1. Constant Fatigue and Weakness

 

Possible vitamin deficiencies:

• Vitamin B12 Deficiency: Essential for the nervous system and energy production. Low levels may cause tiredness, dizziness, and poor concentration.
• Vitamin D Deficiency: Often caused by lack of sunlight. Leads to muscle weakness and persistent fatigue.
• Iron Deficiency (often with B12): Causes anemia, reducing oxygen delivery to cells and leading to exhaustion.

 

 

 

2. Hair Loss and Brittle Nails

 

Related deficiencies:

• Biotin (Vitamin B7): A deficiency may result in thinning hair and brittle nails.
• Zinc: Leads to lifeless hair and hair loss.
• Iron: One of the primary causes of hair thinning in women.

 Hair and nails are often the first areas affected by nutrient deficiencies.

 

 

 

3. Depression and Mood Swings

 

Linked vitamins:

• Vitamin B12 & B6: Crucial for nerve and brain function. Deficiency may lead to mood disorders, anxiety, and depression.
• Vitamin D: Plays a role in serotonin production in the brain. Low levels may increase susceptibility to depression.

• Vitamin B2 (Riboflavin): Cracked lips and sores at the corners of the mouth.
• Vitamin B3 & B12: Can cause tongue inflammation, soreness, and mouth ulcers.

 

 

 

5. Vision Problems & Night Blindness

 

Vitamin A deficiency directly affects eye health. It may result in poor night vision, dry eyes, or blurred vision.

 

 

 

6. Muscle and Bone Pain

 

Deficient nutrients:

• Magnesium: Plays a key role in muscle contractions and may cause twitching or cramps when low.
