Omega 3 fatty acids is essential for health. Pets with allergic (flea allergy dermatitis) auto-immune (pemphigus, rheumatoid arthritis), or inflammatory (arthritis, glomerulonephritis) conditions need more Omega 3 fatty acids.
Omega 3 fatty acids is incorporated into cell membranes throughout the body. When the cell membranes are damaged, fatty acids are released. Most pets, however, have health problems caused by too much inflammation (flea allergies, arthritis, auto-immune disease), so most pets benefit from supplements with higher concentrations of Omega 3 fatty acids.
