Vitamin A supplements are needed by

Question

BlackTom AI · Accepted Answer

The question asks: 'Vitamin A supplements are needed by' and, from the provided data, the identified correct answer is 'people with severe fat malabsorption.'

Because vitamin A is a fat-soluble vitamin, its absorption depends on normal fat digestion and absorption processes. In conditions of severe fat malabsorption (steatorrhea, pancreatic insufficiency, cholestasis, or diseases that impair bile salt production), the absorption of fat-soluble vitamins—including A—is significantly reduced. In such scenarios, oral vitamin A intake may not be sufficient to maintain adequate stores and serum levels, necessitating supplementation to prevent deficiency symptoms like nyctalopia (night blindness) and keratinization of tissues.

If fat absorption is impaired, simply consuming normal amounts of vitamin A won't guarantee adequate absorption; higher or more bioavailable forms or alternative routes of administration may be needed, under clinical supervision.

The prompt does not provide alternative options to compare, so I cannot evaluate other potential distractors. However, the reasoning hinges on the core concept: fat-soluble vitamins (A, D, E, K) require proper fat digestion and biliary/o pancreatic function to be absorbed, and severe fat malabsorption creates a clear indication for supplementation to prevent deficiency.

In a typical exam context, other distractors might suggest that vitamin A supplementation is only for specific populations (e.g., children, pregnant individuals) or only when there is a dietary deficiency, but the correct mechanistic rationale centers on impaired absorption due to fat malabsorption rather than solely dietary intake or a particular demographic group.
