Abstract
Vitamin A in high doses has been found to be highly teratogenic, leading to severe fetal abnormalities if exposure occurs during pregnancy. Hence, prescription vitamin A acne medications like isotretinoin are highly regulated via programs such as iPledge, which intend to avert fetal exposure to isotretinoin and to educate healthcare providers, pharmacists, and patients about the significant risks associated with isotretinoin and its appropriate usage conditions. However, over-the-counter (OTC) vitamin A supplements are not subject to these requirements, and calculating the vitamin A content of these supplements can be difficult due to the lack of Food and Drug Administration (FDA) regulations and inconsistencies in labeling. If the necessary information is provided, ChatGPT, a generative artificial intelligence (AI) tool, can help the general public calculate the vitamin A content of supplements. Nonetheless, supplement manufacturers do not always provide the data necessary for these calculations.
