The problem

Your fish oil is probably doing almost nothing.

Most fish oil supplements — including brands that charge $40, $50, even $60 a bottle — use a form called ethyl ester. It's a synthetic byproduct of the manufacturing process. And your body doesn't absorb it well.

70%
less absorbed. That's how much less the omega-3s (EPA and DHA) your body gets from standard ethyl ester fish oil compared to the natural triglyceride form found in real fish.

Which means if you've been taking fish oil every day and wondering why you're not feeling a difference — this is probably why. You're getting a fraction of the dose on the label.

The inflammation support. The joint comfort. The cardiovascular benefit. The brain health. All of it requires the omega-3s to actually get into your cells. And most fish oil isn't doing that efficiently.

124%
more absorbed. That's the clinical difference between fish oil (rTG, or re-esterified triglyceride) form and standard ethyl ester. The rTG form is structurally identical to omega-3 found naturally in fish — the way your body is designed to receive it.

This isn't a minor difference. It's the difference between a supplement that works and one that you take every day and never feel.

What good omega-3 actually does

Here's what you should be getting — and aren't.

Noticeably less joint stiffness

The active omega-3 (EPA) reduces inflammation at the cellular level. When it's actually absorbed, your joints feel it — especially first thing in the morning.

Real cardiovascular protection

a high-dose serving — 720mg EPA and 480mg DHA — a clinically meaningful dose that supports healthy triglyceride levels and vascular function.

Sharper thinking

DHA, one of the key omega-3s, is a building block of the brain. It supports memory and mental clarity — but only when you're actually absorbing enough of it.

Eye hydration and comfort

Dr. Gills recommends rTG Omega-3 specifically for dry eye. The absorption difference is clinically significant for tear film (the moisture layer of your eye).

Zero fishy burps

The fishy repeat is a sign the oil isn't absorbing. rTG form is absorbed, not lingered — which means no aftertaste and no repeating.

rTG vs. standard fish oil

The form is everything.

Most supplement companies don't talk about form because they use the cheaper version. Here's the difference:

❌ Standard Fish Oil
processed fish oil (ethyl ester, or EE)
A cheaper form made during manufacturing. Your body absorbs up to 70% less of it. Often causes fishy burps. What most brands use because it's cheaper to produce.
✓ Opti + rTG Omega-3
fish oil in its natural form (rTG, or re-esterified triglyceride)
The same form of omega-3 found naturally in fish. Absorbs up to 124% more effectively — what Dr. Gills uses. No fishy aftertaste. What Dr. Gills uses and recommends.

Third-party tested for heavy metals, oxidation stability, and purity. Physician-formulated. Sustainably sourced cold-water fish.

Opti + rTG Omega-3
In Dr. Gills' own words
"Most people taking fish oil are absorbing a fraction of what they think they are. The form matters as much as the dose. I recommend re-esterified omega-3 to my own patients — for dry eyes, for cardiovascular health, for anyone who wants their supplement to actually do something. Ideally, everyone should know their Omega-3 index and work with their healthcare provider to optimize it."

What customers say

People who switched from generic fish oil.

★★★★★

"I was using a generic Omega 3 and when I started Opti + rTG Omega-3 I noticed an improvement of my overall well being right away. I'm very satisfied with the product."

★★★★★

"These omega softgels are amazing. They're incredibly easy to take, and there's absolutely no fishy aftertaste — a huge win compared to other omega-3s I've tried. Taking them every day fits effortlessly into my routine. Reliable, gentle, and genuinely well made."

★★★★★

"I chose this because it uses the rTG form, which is known for better absorption. I take omega-3s mainly for eye health and overall wellness, and this delivers strong the omega-3s (EPA and DHA) without needing a large number of capsules. The softgels are easy to swallow and gentle on my stomach. I plan to continue using it."
