Nordic Naturals vs Life Extension vs Pure Encapsulations vs NOW Foods: The Omega-3 & Cardiovascular Face-Off

Omega-3 supplements are a category where quality differences matter — third-party purity testing (heavy metals, oxidation), EPA/DHA concentration per capsule, and molecular form (triglyceride vs ethyl ester) all change absorption and effect. Nordic Naturals built its brand on those specs. Life Extension, Pure Encapsulations, and NOW Foods compete on the same shelf. Here's how they actually score for cardiovascular and heart-health products on the Vyvata rubric — same 6 dimensions, applied uniformly. Read the rubric →

How the scoring works

Every product is scored on six dimensions — evidence (RCT quality supporting the active ingredients at the label dose), formulation (dose adequacy, bioavailability form, redundancy), manufacturing (third-party testing, GMP, facility audits), safety (adverse-event profile, interactions, dose ceiling), transparency (dose disclosure vs proprietary blends, honest marketing), and sustainability (sourcing, packaging, corporate practice). Tier thresholds: Elite 85+, Verified 70–84, Standard 50–69, Rejected 0–49. Rejected products stay listed with reasons. Full rubric →
