From Ocean to Bottle: The Extraction Process Understanding what is fish oil made from requires looking at the industrial process that transforms raw fish into a stable, consumable product.
From Raw Fish to Refined Oil: Key Steps in the Production Process
The most common sources include: Small, short-lived fish: Anchovies, sardines, and menhaden are foundational to the industry.
