Seaweeds are indiscriminately said to contain significant amounts of vitamin C, but seaweeds are a diverse group, which may limit the ability to generalize. Several studies have been performed on vitamin C in seaweed, and this review covers these findings, and concludes on how much vitamin C is found in seaweeds. A systematic review of vitamin C in 92 seaweed species was conducted followed by analyzing the 132 data entries. The average vitamin C content was 0.773 mg g seaweed in dry weight with a 90th percentile of 2.06 mg g dry weight. The vitamin C content was evaluated based on taxonomical categories of green, brown and red seaweeds (Chlorophyta (phylum), Phaeophyceae (class), and Rhodophyta (phylum)), and no significant differences were found between them. The vitamin C content was compared to other food sources, and this showed that seaweeds can contribute to the daily vitamin C intake, but are not a rich source. Moreover, seasonal variations, analytical methods, and processing impacts were also evaluated.
人们普遍认为海藻含有大量的维生素C，但海藻种类繁多，这可能会限制这种一概而论说法的准确性。针对海藻中的维生素C已经开展了多项研究，本综述涵盖了这些研究结果，并就海藻中维生素C的含量得出结论。我们对92种海藻中的维生素C进行了系统综述，随后分析了132条数据记录。干重下海藻中维生素C的平均含量为0.773毫克/克，第90百分位数为2.06毫克/克干重。基于绿藻、褐藻和红藻（绿藻门、褐藻纲和红藻门）的分类类别对维生素C含量进行了评估，结果发现它们之间没有显著差异。将海藻的维生素C含量与其他食物来源进行了比较，结果表明海藻可以为每日维生素C摄入量做出贡献，但并非富含维生素C的来源。此外，还评估了季节变化、分析方法和加工影响。
