Yes but uncommon: It is possible to overdose on vitamin a but this generally involves extremely large doses for prolonged periods. While some may become toxic from taking 50, 000 units/day x 18 mos., others have ingested 1, 000, 000 units/day x 5 years without problems. Toxicity symptoms include fatigue, headaches, hair loss, muscle/joint pain, nausea, vomiting, dry itchy skin, weight loss & liver damage. See comment:.
