You Weren't Wrong About Omega-3s. You Were Wrong About the Bottle.
Molecular form. Fatty acid ratio. Contaminant panel. Compare it line by line against what's on your counter right now — then decide.
Most fish oil sold for cats is fractionated — chemically stripped down to isolated EPA and DHA, then bonded to an ethanol molecule. That creates an ethyl ester: a synthetic form a cat's body absorbs 50 to 70 percent less efficiently than the natural triglyceride form found in actual fish.
Fractionation also destroys what surrounds those two fatty acids — the DPA reservoir, the natural astaxanthin, the phospholipids, the intact matrix. What's left is two isolated compounds in a form the body barely recognizes.
And nearly every concentrated oil on the shelf is EPA-dominant, because it was formulated for dogs. Cats need more DHA — the specific fatty acid the feline CKD research identified.
Wrong form. Wrong ratio. Wrong species. That's why the numbers kept climbing.
Revillio vs. the Bottle You've Been Using
Pull your current bottle off the counter. Check the label against this. Most of these specs aren't printed anywhere on a concentrated oil — and that absence is itself the answer.
A higher milligram number on the front of a bottle tells you what went in — not what reaches the kidney.

You've Been Lied To by a Label Before. So Don't Take Ours.
Every claim in the table above is documented. Here's what backs each one — and how to request it directly.
Per-Batch Certificate of Analysis
Heavy metals, dioxins, PCBs and PFAS screened on every production batch. Request the COA for your batch code and we'll send it.
Norwegian Aquaculture Standards
Norwegian salmon farming operates under EU contaminant regulation with mandatory testing at every stage of production.
Full Fatty Acid Profile
EPA, DHA, DPA and the complete lipid matrix — not just the two numbers a concentrated oil prints on the front.
Molecular Form Confirmed
Natural triglyceride, not ethyl ester. This is the single spec that determines whether the oil is absorbed or passes through.
You've Had Enough Products That Did Nothing. Here's the Honest Timeline.
Nothing here happens overnight. This is the sequence most owners report, and the order matters — appetite moves first, bloodwork moves last.
The bowl finishes
Palatability shows up immediately or it doesn't. Most cats finish the bowl without warming, tuna water, or coaxing. If your cat refuses it outright, you'll know inside 72 hours — and the guarantee covers that.
The routine gets quieter
Both meals finishing consistently. Less standing over the bowl calculating calories. Some owners report the cat arriving in the kitchen before the food does.
Weight and coat
The scale is usually the first hard number to move. Grooming often returns around the same window — the matted or greasy patches soften first.
Bloodwork
This is the panel that matters. Time your next recheck for at least six weeks in. Ask your vet to compare against the trend line, not just the last value — the shape of the slope is the point.
The Questions Every CKD Owner Asks Us
Not Skin-and-Coat Reviews. Kidney Reviews.
"REPLACE WITH REAL REVIEW — pull verbatim from a customer whose cat has CKD. Prioritize ones that mention a bloodwork panel or the vet's reaction."
"REPLACE WITH REAL REVIEW — best second slot is one about appetite returning, since that's the #1 daily pain point for this avatar."
"REPLACE WITH REAL REVIEW — ideal third slot is someone who explicitly says they'd tried other fish oils first. That review does the most conversion work on this page."
