Morphology
The meaning is directly compositional: 'vitamin' (a nutrient) combined with the identifier 'A' names a specific vitamin. A B1 learner who knows 'vitamin' and that letters can label vitamin types can infer this refers to the particular vitamin associated with vision and health, a pattern common across languages.
Etymology
Vitamin A gets its name from early scientists who named important food substances with letters, and the first one they found was called A. They found Vitamin A in foods like liver and carrots and noticed it 'helps eyesight', so today the name means the vitamin needed for 'vision' and healthy skin.
