Mnemonic Tricks
How It Maps
| Cue | Maps To |
|---|---|
| Night | Vitamin A → Night Blindness |
| Brings | Vitamin B1 → Beriberi |
| Bad | Vitamin B3 → Pellagra (Bad skin) |
| Problems | Vitamin B12 → Pernicious Anaemia |
| Kills Slowly | Vitamin C → Scurvy |
| Recklessly | Vitamin D → Rickets |
| Silently | Vitamin E → Sterility |
| Bleeding | Vitamin K → Bleeding |
Why It Sticks
Each disease keyword sounds like or starts with the same letter as the disease it represents — Night for Night Blindness, B for Beriberi, R for Rickets, etc.
A for eyes that cannot see at night, B1 makes your legs lose their might, B3 gives pellagra's painful three Ds, C makes your gums bleed with ease, D bends the bones — rickets' sign, E takes fertility from the line, K makes your clotting fall behind — vitamins that blow your mind!
Why It Sticks
Each vitamin pairs with a vivid symptom image — visual (night blindness), physical (weak legs), painful (gum bleeding). Multi-sensory encoding beats rote repetition.

Pellagra (Vitamin B3/Niacin deficiency) is remembered by the 3 Ds: Dermatitis, Diarrhoea, Dementia. A 4th D (Death) follows if untreated.
Which vitamin deficiency causes Scurvy?
Vitamin C (Ascorbic acid) deficiency causes Scurvy — characterized by bleeding gums, loose teeth, poor wound healing, and fatigue. Historically affected sailors on long voyages without fresh fruit.
Are vitamins important for NEET?
Yes, vitamins appear in NEET Biology under nutrition and biomolecules. Common questions: fat vs water soluble classification, deficiency disease matching, and chemical names of vitamins.
