Why Precise Testing Matters

  • Dosing: Accurate EPA/DHA content underpins evidence-based dosing for cardiovascular, cognitive, and healthy inflammatory support.
  • Label Integrity: Mislabeling is surprisingly common and many supplements contain less EPA/DHA than claimed.
  • Patient Trust: Inconsistent potency can undermine provider recommendations and patient adherence.

Choosing a fish or algae oil backed by third-party testing ensures consistent EPA/DHA levels and reinforces the credibility of your recommendations.
