How to read this test

Assess whether you present clinical signs of vitamin A deficiency: dry eyes, night vision, rough skin, acne, dry mucous membranes. Free, 10 questions.

Vitamin A exists in 2 forms: retinol (from animal sources, directly usable) and beta-carotene (from plant sources, converted by the liver). It plays a fundamental role in vision, the integrity of skin and mucous membranes, and the proper functioning of the immune system. This questionnaire helps you identify clinical signs suggestive of a deficiency, which is common in vegans, people suffering from intestinal malabsorption, or those with a low-fat diet.

Strengths

  • Rapid identification of clinical signs
  • Simple self-assessment test
  • Detection of skin, visual and mucosal complications related to retinol deficiency

Limitations

  • Does not replace blood testing
  • Some signs may have other causes
  • Limited sensitivity for subclinical deficiencies
