Omega-3 is a group of essential fatty acids, widely renowned for its anti-inflammatory properties. These have been shown to improve gut health (Ephraim, I Jackson, Yerramilli and E Jewell, 2020), improve symptoms associated with osteoarthritis (Moreau et al., 2012) and reduce risk factors for brain aging in elderly dogs (Pan, Kennedy, Jönsson and Milgram, 2018). The most practical way to provide these is to feed products containing a source of oily fish.
