DermGard™ with MSM contains all the essential nutrients to promote healthy skin and a shiny coat in dogs and cats. It incorporates Omega-3 from fish. Fish oil Omega 3 fatty acids (EPA and DHA) are capable of modifying inflammatory skin responses in healthy dogs. Typical pet foods lack Omega 3 but are rich in Omega 6. DermGard™ also includes Omega 6 to balance Omega 3 and 6 contents to the optimal ratio of 1:7, but Omega 6 is not considered a dietary supplement and is therefore not included in the list of ingredients. DermGard™ also contains 99.9% pure PurforMSM® and other essential vitamins and minerals important for skin health. This advanced, highly palatable formulation is light years beyond simply providing fish oil and is recommended as a first line defense for dogs and cats with common dermatologic issues. Working from the inside out!
