2020年2月5日，应欧盟委员会的要求，欧盟食品安全局（EFSA）营养、新型食品和食品过敏原小组（NDA）就虾青素（astaxanthin）在食品补充剂中作为新型食品的安全性发布意见。
经过评估，欧盟NDA小组认为这种虾青素的联合暴露对成人是安全的。
部分原文报道如下：
Following a request from the European Commission, the Panel on Nutrition, Novel Foods and Food Allergens （NDA） was asked to deliver an opinion on the safety of astaxanthin when used as a novel food in food supplements at maximum levels of 8 mg/day, taking into account the overall cumulative intake of astaxanthin from all food sources. In 2014, the NDA Panel assessed the safety of the novel astaxanthin‐rich ingredient derived from microalgae Haematococcus pluvialis in the context of an application submitted under Regulation （EC） No 258/1997. In that opinion, the NDA Panel considered that the acceptable daily intake （ADI） for astaxanthin was 0.034 mg/kg body weight （bw） set by the EFSA FEEDAP Panel in 2014. In 2019, the FEEDAP Panel adopted an opinion which concerned the renewal of the authorisation of dimethyldisuccinate‐astaxanthin and a new use of the additive for crustaceans and other fish than salmonids. In that assessment, the FEEDAP Panel derived a new ADI of 0.2 mg astaxanthin/kg bw which replaced the ADI of 0.034 mg/kg bw established in 2014. By taking into account an updated exposure assessment for astaxanthin from the background diet （fish and crustaceans） in combination with 8 mg from food supplements, the NDA Panel concludes that （i） such combined exposure to astaxanthin is safe for adults, （ii） 14 to < 18 years old adolescents reach the ADI, and （iii） the ADI is exceeded by 28% in children aged 10 to < 14 years and up to 524% in infants aged 4–6 months.
