Level 1
Direct lifetime feline support
The strongest layer on the site: ingredients inherited from the controlled lifetime cat trial.
Full Transparency
Every ingredient. Every dose. Every reason.
11 active ingredients. Exact doses. No proprietary blends. This page is meant to make the formula easy to scan without hiding the logic underneath it.
How To Read The Formula
The formula is disclosed in full, with the evidence labeled plainly.
Some ingredients come directly from the cat longevity trial. Others are included for strong feline or mechanistic support. The point is not to pretend every ingredient has identical proof. The point is to keep the hierarchy visible.

Evidence Legend
The label on each ingredient tells you how much weight to give the evidence before you read the technical note.
Level 2
Meaningful feline support
Published feline or closely adjacent support that matters, but without the same lifetime design.
Level 3
Mechanistic longevity support
Included for strong rationale and broader evidence, but labeled honestly as the weaker layer.

Active Ingredients
Every active is disclosed at the formula level.
The first sentence tells you why an ingredient is here in plain language. The smaller note keeps the technical context visible without making the page read like a paper.
NAD+ Restoration
Nicotinamide Riboside (Niagen®)
75 mgLevel 3
Included to support cellular energy and DNA repair as NAD+ declines with age.
Niagen® is the branded NR form used here, chosen for the broader NAD+ literature around mitochondrial function, DNA repair, and sirtuin signaling.
Cardiac & Retinal
Taurine
250 mgLevel 2
Included because cats require taurine from the diet and deficiency directly harms the heart and retina.
It also supports mitochondrial function, which is why taurine stays foundational rather than optional in an aging-cat formula.
Renal & Anti-inflammatory
EPA + DHA (Algal)
150 mg combinedLevel 1
Chosen for kidney, inflammatory, and cognitive support, using algal omega-3s instead of fish oil.
This is one of the ingredients inherited from the Cupp lifetime blend and kept in the formula at a fully disclosed combined dose.
Antioxidant
Vitamin E
30 IULevel 1
Included because the lifetime cat trial supports it directly at this exact dose.
In that work, supplemented cats showed lower mortality, lower disease incidence, and slower losses in body weight and lean body mass.
Antioxidant
Vitamin C (Calcium Ascorbate)
65 mgLevel 2
Included to extend antioxidant coverage alongside Vitamin E, using the calcium ascorbate form.
The form choice matters here because the formula avoids ordinary ascorbic acid in this context.
Antioxidant
Beta-carotene
1 mgLevel 1
Included as a safer provitamin A strategy instead of preformed vitamin A.
It is also part of the lifetime trial blend at the exact disclosed dose, which keeps the logic anchored to cat-specific data.
Prebiotic
Chicory Root (FOS)
50 mgLevel 1
Included as a prebiotic layer to support beneficial gut bacteria.
In the lifetime cat trial, the supplemented group showed a strong positive Bifidobacteria response, which is why this ingredient remains in the formula.
Anti-inflammatory
Quercetin
12 mgLevel 2
Included for inflammatory control and added resilience around the NR pathway.
The rationale centers on feline anti-inflammatory benefits plus PI3K/mTOR and CD38-related longevity logic, which is useful but still below the direct cat-trial tier.
Mitochondrial
CoQ10 (Ubiquinone)
10 mgLevel 3
Included for mitochondrial, renal, and cardiac support in a system that runs hard with age.
The formula uses ubiquinone and treats CoQ10 as a modern addition rather than a direct holdover from the cat longevity trial.
Liver
NAC
30 mgLevel 2
Included to support glutathione production and core liver defense.
For cats, that matters because glutathione is a primary detoxification pathway and an important part of basic antioxidant resilience.
Cognitive
B-Vitamin Complex
B1 0.5mg, B6 0.3mg, B12 5mcg, Folate 50mcgLevel 2
Included for cognitive support, nerve health, and common senior-cat nutrient gaps.
The rationale comes from feline cognition work pairing B vitamins with EPA/DHA and antioxidants, plus the frequency of B12 deficiency in senior and CKD cats.
Excipients
Non-active ingredients should be disclosed cleanly too.
The active formula does most of the work, but a transparent page should still explain what supports stability, flow, and palatability.
5-10 mg
Phytic acid
Used as a metal chelator from rice bran extract to reduce lipid peroxidation risk around the omega-3 layer.
As needed for acceptance
Feline palatant
A meat-based flavor system so the formula is realistic for cats to eat, not just impressive on paper.
If needed during manufacturing
Silicon dioxide
A simple flow agent, disclosed plainly because the page should not hide non-active ingredients either.
