Key Takeaways

  • Refrigerate or freeze fish oil to prevent oxidation (polyunsaturated fats degrade at room temperature).
  • Store bulk fish oil in the freezer, then transfer a single bottle to the fridge for daily use.
  • Choose fish oil brands with third-party testing showing total oxidation (TOTOX) below 10 for freshness.
  • Avoid consuming oxidized fish oil – it’s harmful to health.

Notable Quotes

“You need to put it in the fridge and also make sure you’re getting a quality brand… You want to have a total oxidation ideally less than 10.”

Bottom Line

Store fish oil in cold temperatures (freezer/fridge) and verify its freshness via third-party testing to maximize benefits and avoid oxidized fats.
