Did you know?
Fish oil became a mainstream human supplement in the 1970s after researchers noticed that Greenlandic Inuit had very low rates of heart disease despite a high-fat diet — the key difference was the high omega-3 content of their fish-heavy diet. The same omega-3 EPA and DHA that protect human cardiovascular health provide anti-inflammatory benefits for aging dog joints.

What You Need to Know
Fish oil provides EPA and DHA — the most bioavailable forms of omega-3 fatty acids with the most direct anti-inflammatory effect. For senior dogs the benefits are significant: reduced joint inflammation from arthritis improved coat and skin health cognitive support through DHA and cardiovascular health support. The dose that provides therapeutic benefit is higher than what most dog foods provide. A senior dog on standard kibble without significant fish oil content benefits substantially from supplementation. Store in refrigerator after opening to prevent rancidity and replace every 3 months.
