How do I choose a good-quality fish oil?

Short answerLook at the actual EPA + DHA per serving (not just total fish-oil mg), choose products tested for purity and freshness (low oxidation, third-party verified, heavy-metal screened), and prefer triglyceride-form oils. Sustainable sourcing and a sensible price round it out. Freshness is what prevents fishy burps and lost benefit.

Fish oils vary enormously in strength and quality, so the label needs a closer read than most.

What to check

  • EPA + DHA content: the numbers that matter — a "1000 mg fish oil" capsule may contain far less actual omega-3.
  • Purity & freshness: third-party tested for heavy metals and oxidation; rancid oil is common and counterproductive.
  • Form: triglyceride (rTG) form is generally better absorbed than ethyl ester.
  • Sourcing: sustainable, reputable brands; sensible price for the EPA/DHA delivered.

This ties directly to the burp question — a fresh, well-made oil is "small and tasteless" with "no fishy burping," whereas a cheap oxidised one announces itself. Pay for verified quality, not just a big front-of-label number.
