Vitamin A is critical for vision, growth, and many cell functions. High concentrations of Vitamin A are seen with renal failure, but this is not associated with toxicity and excessive ingestion. High concentrations are associated with bone fractures. Low concentrations of Vitamin A are consistent with fat malabsorption and are rarely due to inadequate diet.
