• B族维生素
  用于治疗急性及慢性肝炎、肝硬化、肝性昏迷、脂肪肝、糖尿病等。
  抗氧化剂
  被称为“万能抗氧化剂”，更是自由基捕手，是机体细胞利用糖类等能源物质产生能量所需的一种限制性必需营养物质，广泛用于治疗和预防心脏病、糖尿病等多种疾病。一般认为它能保存和再生其它抗氧化剂，如维生素C和E等，并能平衡血糖浓度。有效增强体内免疫系统，免受于自由基的破坏。
  它对多种病症具有治疗功效：肝病、糖尿病、人类后天免疫不全带原者、艾滋病、牛皮藓、湿疹、烧伤、皮肤癌、多发性硬化症、帕金森氏症、神经科方面的疾病、风湿病、风湿性关节炎、红斑性狼疮、硬皮症、自体免疫方面的疾病、白内障、其它眼科疾病、心脏病、中风、动脉硬化、用于急性及慢性肝炎、肝硬变、肝性昏迷、脂肪肝等疾病。
  一种重金属螯合剂
  2HLa+ M2+（二价金属） ====2H+ + [M(La)4]-，介电常数很高
  可抑制早老性痴呆
  将硫辛酸类药物这种价格低廉的糖尿病辅助治疗药物与治疗阿尔茨海默症的常用药物乙酰胆碱酯酶抑制剂配合使用，可以有效抑制病人病情发作，并使部分病人的病情得到缓解。
  作用力很强
  它参与能量代谢，增加其它抗氧化剂消灭自由基的能力，促进恢复，提高人体增肌减脂的能力，还可以提高胰岛素敏感性，帮助肌酸导入肌肉细胞，硫辛酸是挡住衰老的七种营养品之一。可以美颜、活化细胞、改善生发。
