What's actually in Nutrish PEAK?
We analyzed Nutrish PEAK Prey-Inspired Turkey & Venison Grain-Free, the flagship PEAK formula. The first five ingredients are turkey, turkey meal, peas, pea starch, and pea protein.
Fresh turkey followed by turkey meal is a strong start — same strategy premium grain-free brands use. Then the pea chorus arrives: whole peas at three, pea starch at four, pea protein at five. That's a legitimate grain-free formulation choice, but it's the exact ingredient stacking pattern the FDA has flagged in its ongoing investigation of diet-associated dilated cardiomyopathy. Chicken fat preserved with mixed tocopherols handles the lipid load. Venison and dried egg product appear further down; ground flaxseed and salmon oil add omega-3s; taurine rounds out the amino-acid supplementation. Shop on Amazon →
The good stuff
Turkey-and-turkey-meal-first is a genuine premium signal. Two concentrated named poultry sources up front deliver both palatability (fresh turkey) and protein density (turkey meal — roughly 3x more protein-dense than fresh meat). Venison at position seven is a nice second named meat — a novel protein for dogs who haven't been exposed to chicken fatigue or poultry sensitivities.
Taurine supplementation is the single most important inclusion in this formula. Legume-heavy grain-free kibble has been the focus of the FDA's DCM investigation; one working hypothesis is that high-legume formulas may interfere with taurine bioavailability. Guaranteed supplemental taurine mitigates that risk directly. Nutrish PEAK is one of the few mass-market grain-free brands to include it by default.
Ground flaxseed and salmon oil together supply omega-3 fatty acids (flaxseed contributes ALA, salmon oil contributes EPA/DHA). Dried egg product is a high-biological-value protein contribution. Chicken fat is preserved with mixed tocopherols — no BHA, BHT, or ethoxyquin.
The not-so-good stuff
The pea stack is the formula's biggest question mark. Peas, pea starch, and pea protein occupy positions three, four, and five — meaning a substantial portion of the carb and plant-protein load comes from a single botanical family. "Ingredient splitting" is a real dynamic here: three separate pea-derived entries at the top of the list can collectively outweigh the turkey. Even with taurine supplementation, the legume density is what the FDA has been watching.
Tapioca starch at position nine adds another pure-starch carb source with minimal nutritional contribution beyond calories. Gluten-free and hypoallergenic, but nutritionally thin.
No probiotics, no whole fruits or vegetables, no dried berries or spinach. The whole-food layer that competitors like Acana and Orijen lean on is absent.
How it compares
Nutrish PEAK's B (78/100) is a full 13 points ahead of standard Rachael Ray Nutrish (C/65) — the premium-line lift is real, not cosmetic. Against other grain-free B-tier brands like Blue Buffalo Wilderness (B/75) and Taste of the Wild (B/78), PEAK holds its own — the turkey-and-venison profile is differentiated, and the taurine inclusion is an edge most competitors don't explicitly offer.
The step up to A-tier grain-free — Orijen (A/90), Acana (B/88), Wellness CORE (A/90) — costs noticeably more per pound but delivers more meat density and less pea reliance.

The bottom line
Rachael Ray Nutrish PEAK Prey-Inspired Turkey & Venison earns a B grade (78/100) from KibbleIQ. Turkey and turkey meal up front, venison as a second named protein, guaranteed taurine, and clean preservation make it a legitimate premium step-up from standard Nutrish. The three-way pea stack at positions three through five is the single biggest reason it sits at 78 instead of 85-plus — if you're DCM-conscious, the taurine inclusion helps, but a legume-lighter A-tier formula would help more.
