A recent review looked into how vitamins, minerals, and plant nutrients affect dogs' immune systems. It's important since many dog foods claim to improve immune health, but actual evidence on their effectiveness has been limited. The review found that while vitamins C and E showed some benefits, more research is needed to fully understand how these nutrients and minerals influence immunity. Organic sources of minerals seemed promising for immune response, but the findings call for more studies to back up these claims.

For dog parents, this means being cautious about relying solely on food that claims to boost your furry friend's immune system. Instead, consider a balanced diet that includes real food, rich in natural nutrients. While some vitamins may help, it’s a good idea to consult your vet about your dog's specific nutritional needs. Knowing about these nutrients can help you make informed choices to support your dog's health every day.
