Did you know?
Fish oil became a mainstream 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 EPA and DHA that protect human cardiovascular health provide anti-inflammatory benefits for aging dog joints. Annual global fish oil production is approximately 1 million tonnes primarily from anchovies harvested off the coast of Peru.
