Trends in the pet food industry are driven by the humanization of pets, favoring the inclusion of functional ingredients or supplements that promote animal health. Several commercial diets claim to include supplements with benefits for dogs' immune function, but in vivo evidence that supports their efficacy remains limited. This literature review aimed to better understand the current knowledge on the effects of vitamins, minerals and phytonutrients on dogs' immune function. A total of 27 peer-reviewed articles were identified in PubMed and Web of Science databases. Although vitamin supplementation is often claimed to support immune function, only two studies promoting slight benefits of vitamins C and E were found. The limited research on minerals suggests that organic sources promote a better immune response. Studies evaluating the inclusion of different phytonutrients show that these compounds might exert immunomodulatory and anti-inflammatory effects. Despite the increased popularity of commercial diets claimed to support the immune response of dogs, further research is needed in order to substantiate their effects. This knowledge will contribute to the development of effective diets to enhance immune health in dogs.
宠物食品行业的发展趋势受到宠物人性化的推动，倾向于添加促进动物健康的功能性成分或补充剂。一些商业宠物食品声称含有对犬类免疫功能有益的补充剂，但支持其功效的体内证据仍然有限。这篇文献综述旨在更好地了解目前关于维生素、矿物质和植物营养素对犬类免疫功能影响的知识。在PubMed和科学网数据库中总共鉴定出27篇同行评议文章。尽管经常有人声称补充维生素能支持免疫功能，但仅发现两项研究表明维生素C和E有轻微益处。关于矿物质的研究有限，表明有机来源能促进更好的免疫反应。评估不同植物营养素添加情况的研究表明，这些化合物可能具有免疫调节和抗炎作用。尽管声称支持犬类免疫反应的商业宠物食品越来越受欢迎，但仍需要进一步研究以证实其效果。这些知识将有助于开发有效的宠物食品，以增强犬类的免疫健康。
