Overview
Excessive or supraphysiological intake of fat-soluble vitamins (A, D, E) can lead to adverse health effects despite their essential roles in maintaining health 13.Diagnosis
Self-reported health status (SRH) can correlate with plasma levels of fat-soluble vitamins, particularly in observational studies 1.
No specific diagnostic tests are highlighted for harmful patterns of vitamin use; monitoring plasma concentrations may provide insights 1.Management
Avoid unnecessary supplementation; focus on obtaining vitamins through a balanced diet 2.
Monitor individuals at risk of supraphysiological intake, especially those using high-dose vitamin supplements 3.Special Populations
No specific guidance provided for pregnancy, pediatrics, or elderly populations regarding harmful vitamin use patterns 123.Key Recommendations
Limit the use of vitamin/mineral supplements to those with confirmed deficiencies or specific medical indications to avoid unnecessary intake 2 (Evidence: Strong).
Monitor plasma levels of fat-soluble vitamins in individuals regularly consuming high-dose supplements to prevent toxicity 13 (Evidence: Moderate).
Promote a balanced diet rich in diverse nutrients to meet vitamin requirements rather than relying on supplements for the general population 2 (Evidence: Strong).References
