: The present study demonstrates that apart from the well-known toxicity of liposoluble vitamins, some hydrosoluble vitamins may also exert toxicity; thus, routine supplementation with vitamins or ingestion of fortified foods should not be considered harmless. The study addresses the possible correlations between the physico-chemical properties and the side effects of vitamins when taken in high doses or for a too long a period. : The FAFDrugs4.0 computational tool was used for computational assessment of the ADMET profile of several hydro- and liposoluble vitamins. : ADMET analysis revealed the following major data: vitamin B3 and B13 showed reduced structural complexity; thus, a relative toxicological potential may be exerted. Vitamins B1 and B7 were found to have good oral absorption and thus good bioavailability, while Vitamin B3 was found to have decreased oral absorption. In addition, all of the liposoluble vitamins reflected higher complexity, much greater than most of the potentially therapeutically-proven compounds. : The present study emphasizes the importance between the physico-chemical properties of vitamins and their possible toxicological impact.
本研究表明，除了众所周知的脂溶性维生素的毒性外，一些水溶性维生素也可能具有毒性；因此，常规补充维生素或摄入强化食品不应被认为是无害的。本研究探讨了在高剂量或长时间服用时，维生素的物理化学性质与其副作用之间可能存在的相关性。使用 FAFDrugs4.0 计算工具对几种水溶性和脂溶性维生素的 ADMET 特性进行了计算评估。ADMET 分析揭示了以下主要数据：维生素 B3 和 B13 的结构复杂性降低；因此，可能会产生相对的毒理学潜力。发现维生素 B1 和 B7 具有良好的口服吸收性，因此具有良好的生物利用度，而维生素 B3 的口服吸收则降低。此外，所有脂溶性维生素的复杂性都较高，远高于大多数具有潜在治疗作用的化合物。本研究强调了维生素的物理化学性质与其可能产生的毒理学影响之间的重要性。
