One screen per section. Cover the right column and test yourself. CAPF Paper I tests the vitamin to chemical name to deficiency disease chain, plus a few minerals and endocrine disorders. The figures and associations below are standard textbook facts.

Fat-soluble vs water-soluble: the key split

Property Fat-soluble (A, D, E, K) Water-soluble (B-complex, C)
Storage in body Stored in liver and fatty tissue Not stored (except B12); excreted in urine
Need in diet Less frequent Daily intake needed
Toxicity risk Can accumulate to toxic levels Excess usually excreted

Vitamins: name, source, deficiency

Vitamin Chemical name Rich source Deficiency disease
A Retinol Carrots, green leafy vegetables, liver Night blindness; xerophthalmia
B1 Thiamine Whole grains, pulses Beriberi
B2 Riboflavin Milk, eggs, green vegetables Cheilosis, cracked lips, glossitis
B3 Niacin Meat, groundnut, cereals Pellagra
B5 Pantothenic acid Meat, whole grains Burning feet syndrome
B6 Pyridoxine Fish, banana, potatoes Anaemia, dermatitis
B7 Biotin Egg yolk, liver Dermatitis, hair loss
B9 Folic acid Leafy greens, citrus Anaemia; neural tube defects in foetus
B12 Cyanocobalamin Meat, fish, dairy Pernicious anaemia
C Ascorbic acid Citrus fruits, amla, guava Scurvy (bleeding gums)
D Calciferol Sunlight, fish oil, egg yolk Rickets (children); osteomalacia (adults)
E Tocopherol Vegetable oils, nuts Sterility (in animals), red cell fragility
K Phylloquinone Green leafy vegetables Excessive bleeding (poor clotting)

High-yield single facts

Fact Detail
Vitamin from sunlight Vitamin D (synthesised in skin via ultraviolet)
Vitamin for blood clotting Vitamin K
Vitamin that an excess of water cannot wash out (stored) Vitamin B12
Vitamin not found in animal foods normally Vitamin C is abundant in fruits, scarce in meat
Antioxidant vitamins A, C and E
Vitamin made by gut bacteria Vitamin K and some B vitamins

Mineral deficiencies

Mineral Function Deficiency effect
Iron Haemoglobin formation Anaemia
Iodine Thyroid hormone synthesis Goitre; cretinism in children
Calcium Bones, teeth, clotting Weak bones, poor clotting
Phosphorus Bones, energy molecules Bone and dental problems
Sodium and potassium Nerve and muscle function, fluid balance Cramps, weakness, irregular heartbeat
Fluorine Tooth enamel Dental caries (deficiency); fluorosis (excess)
Zinc Enzymes, immunity, growth Poor growth, impaired healing
Disorder Cause
Diabetes mellitus Insufficient insulin (pancreas)
Goitre Iodine deficiency affecting the thyroid
Cretinism Thyroid hormone deficiency in children
Dwarfism / Gigantism Deficiency / excess of growth hormone
Diabetes insipidus Deficiency of antidiuretic hormone (ADH)
