More omega-3 per softgel, in triglyceride form.
Standard fish oil (about 30% EPA+DHA) is a natural triglyceride. To make a concentrated, high-strength oil, the omega-3s are usually converted to ethyl ester (EE) form. Re-esterification (rTG) converts the concentrate back to a triglyceride form, similar to the structure found in fish. Studies comparing rTG with EE have reported higher EPA and DHA uptake, especially when taken without a fatty meal.
That means:
No label games. Every number is real.

Every batch is independently lab tested, with its manufacture date and freshness results on the batch report, and shipped directly from our warehouse.
The label rarely tells you this part. Here's what actually determines whether an omega-3 supplement does anything — and where most capsules on the shelf fall short.
Ethyl ester (EE) fish oil concentrates are absorbed less efficiently than triglyceride form — in a single low-fat dose, published human studies show EE absorption at roughly a third of triglyceride form. Taking it with a meal narrows that gap, which is why we recommend taking Pure Serving with your main meal.
See the absorption data →Fish oil oxidizes over time — and oxidized oil makes the fishy burps and off-taste people associate with omega-3 supplements worse. Stock sitting in warehouses for months adds to it, which is why we test freshness on every batch.
Without independent batch-level testing, the actual EPA and DHA content in a bottle can vary from what's printed on the label. A one-time lab test at launch doesn't guarantee batch #47 matches batch #1.
This is exactly why rTG form, freshness testing, and independent per-batch testing are the three things Pure Serving checks before a bottle ships — not just at launch, every batch.
High-strength fish oil concentrates are usually made in ethyl ester (EE) form, which published human studies show is absorbed less efficiently than triglyceride form when taken without a fatty meal. Re-esterified Triglyceride (rTG) converts the concentrate back to a triglyceride form, similar to the structure found in fish. This single-dose gap narrows when either form is taken with a high-fat meal (which is why we recommend taking Pure Serving with your main meal) — but over months of regular use, rTG still builds a measurably higher blood omega-3 level than EE. See the 6-month comparison below.

The case for rTG form isn't marketing language — it's built on decades of human absorption studies and a 6-month real-use trial comparing rTG fish oil with ethyl ester (EE) fish oil. Here's what the published research actually found.
in a 6-month trial: rTG, ethyl ester or placebo
In a 6-month randomised trial, 150 volunteers took rTG, ethyl ester or a corn-oil placebo. At the same daily dose of EPA+DHA, the rTG group raised their blood omega-3 index further than the ethyl ester group — a real-world result from months of regular use, not a single-dose snapshot.
Neubronner et al., Eur J Clin Nutr (2011)→DHA absorption in triglyceride form
In a single low-fat dose, DHA from fish oil triglycerides was absorbed 57% as well as free fatty acid, versus just 21% for ethyl ester DHA. This gap narrows with a high-fat meal for both forms — which is why the 6-month, real-use result above is the stronger evidence.
Lawson & Hughes, Biochem Biophys Res Commun (1988)→Apparent bioavailability seen for the EE form
A 2014 narrative review of omega-3 bioavailability found that it seems to be lowest for the ethyl ester (EE) form and highest for the free fatty acid form, while noting methodological limitations across studies.
Ghasemifard et al., Progress in Lipid Research (2014)→mg/dL triglycerides at 1,000–2,000 mg/day
A 2025 meta-analysis of 21 randomized controlled trials (~1,950 adults with metabolic syndrome or its components) found triglyceride reductions of about 25–32 mg/dL at 1,000–2,000 mg/day EPA+DHA, the range that includes our 1,500 mg serving. Larger reductions (about 57 mg/dL) were seen above 2,000 mg/day taken for more than 12 weeks.
