2023年10月25日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就一种甜菜碱锰复合物（manganese(II)-betaine complex）作为所有动物饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组得出结论，在建议的使用条件下，该添加剂对所有动物物种都是有效的。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of manganese(II)-betaine complex as a nutritional feed additive for all animal species and categories. based on the tolerance study performed in chickens, the FEEDAP Panel concluded that the additive is safe for chickens for fattening when used up to the maximum proposed level of manganese in feed; this conclusion was extrapolated to all animal species and categories at the corresponding maximum manganese levels in complete feed (100 mg Mn/kg feed for fish and 150 mg Mn/kg feed for all other animal species). The FEEDAP Panel concluded that the use of additive in animal nutrition does not represent a concern for consumer safety or for the environment. The additive is irritant to the eyes, but not irritant to skin. Owing to the presence of nickel the additive is considered to be a dermal and respiratory sensitiser. The Panel concluded that the additive is efficacious as a nutritional additive for all animal species under the proposed conditions of use.
