How we verify

The brand submits the formula. We read the supplement facts panel and weigh dose, form and synergy against the clinical evidence. Labs test. IngredientMD verifies. The fee pays for review time, never for the outcome.

    The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.

Across 90 trials in 72,598 people, higher daily DHA and EPA intake lowered blood triglycerides and non-HDL cholesterol in a near-linear way, most clear above about 2 g a day.

Meta-analysis, 2026

Pooling nine placebo-controlled eccentric-exercise trials in healthy adults, long-chain omega-3 fats reduced delayed onset muscle soreness (Hedges g -0.75) and the muscle-damage marker creatine kinase (-0.40) and improved muscle strength (0.45) and range of motion (0.93) at the point of worst impairment.

Across seven trials in 439 adults with elevated liver fat, fish oil moved triglycerides (standardised mean difference -0.40), the liver enzyme AST (-0.29), insulin resistance measured by HOMA-IR and waist circumference (-0.31) in a favourable direction, while ALT, GGT, body mass index and LDL cholesterol showed no detectable change.

Pooling 15 trials in pregnant women, fish oil capsules showed no detectable difference from placebo in blood sugar or blood lipid measures overall, with a lower HOMA-IR (mean difference -0.60) in the subgroup taking under 200 mg of EPA.

What this formula earned

Every one of these is a fact the engine could ground.

Each line below was derived from this formula's own record at the time of verification. Nothing here was written by the brand, and nothing can be added that the evidence does not carry.

  • Studied in people15 human studies on Fish Oil back this formula, each one cited.
  • A mechanism that is settledHow Fish Oil and Omega-3 Fatty Acids work is settled pharmacology.
  • Recent work on the recordThe most recent study on this record was published in 2011.
  • Why this formatIt is a softgel, so the active is already dissolved in oil and the shell keeps it away from air and light.
  • Full label disclosureEvery ingredient on this label carries its own declared amount.
  • Where it comes from and how it is madeFish Oil is made by animal.
  • Positions this formula already qualifies forThis formula already qualifies for positions beyond the one it is sold into, on the evidence it carries.

What the trials show

What the trials show about timing.

Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.

  • Fish Oilabout 4 to 8 weeks in blood plasma, about 6 months in red blood cellsBuilds with daily use

    In the trial record, EPA in blood plasma plateaus after 4 to 8 weeks of daily fish oil, while EPA in the red blood cell membrane rises with a 28 day half-life and reaches a steady state at about 180 days.

  • Fish Oilabout eight weeks of daily useBuilds with daily use

    In a randomised single-blind trial, 20 participants took either fish oil supplying 1,296 mg EPA and 864 mg DHA daily or flaxseed oil for eight weeks, with erythrocyte membrane and plasma samples drawn at weeks 0, 4, 8, 10, 12, 14, 16 and 24. On fish oil, erythrocyte membrane EPA rose 300 percent and DHA rose 42 percent by week eight. Levels held until about week 12 and then declined across the post-supplementation sampling, faster in plasma phospholipids than in erythrocyte membranes. Membrane fatty acid content was measured, not a symptom, and this is one trial of 20 people.
