Not All Eggs Are Created Equal: What the Lab Actually Found in a Sunnyside Egg

At Sunnyside Egg Co., we've always believed that how a hen is raised shows up in the egg. But belief is one thing, and proof is another. So we did what most egg brands never do: we sent our eggs to Edacious for independent nutrient testing and put the results side by side with the USDA's standard nutritional profile for a large egg.

We didn't cherry-pick a friendly lab or a flattering metric. We tested for macronutrients, fatty acids, vitamins, minerals, carotenoids, and even heavy metals — the full picture, the good and the honest trade-offs. Here's what came back.

The headline: dramatically more of the nutrients people actually care about

The standout result is vitamin E. A Sunnyside egg carries roughly 676% more vitamin E than the USDA standard — 4.07 mg versus 0.53 mg. Vitamin E is a fat-soluble antioxidant, and levels like these are a direct reflection of what a hen eats and how she lives. You don't get numbers like that from a bird in a cage eating a minimal ration.

Vitamin E wasn't alone. Across the B-vitamin family, Sunnyside eggs tested significantly higher: 390% more niacin (B3), 106% more thiamin (B1), 51% more B5, and 36% more riboflavin (B2). These are the vitamins your body uses to turn food into usable energy, and they showed up in abundance.

A better fat profile, not just more fat

The fat story is where the testing gets genuinely interesting, because it's not about quantity — total fat was actually a hair lower than the USDA egg. It's about quality.

Sunnyside eggs delivered 73% more omega-3 fatty acids and 67% more DHA, the specific omega-3 most associated with brain and eye health. But the number we're proudest of is the ratio. The modern diet tends to be flooded with omega-6 and starved of omega-3, and a healthier egg helps close that gap. The USDA standard egg has an omega-6 to omega-3 ratio of about 15.6 to 1. A Sunnyside egg comes in at 6.9 to 1 — less than half. Lower is better here, and this is one of the clearest signals of a bird raised on a richer, more varied diet.

Minerals, including a few pleasant surprises

On the mineral side, Sunnyside eggs tested higher nearly across the board: 107% more selenium, an important antioxidant mineral; 50% more magnesium; 46% more potassium; 34% more phosphorus; and 26% more iron. We also found meaningfully higher levels of trace minerals like manganese and copper — minerals that come through in the diet of a well-fed, pasture-raised hen.

Why any of this matters

An egg is one of the few foods that reflects, almost perfectly, the life of the animal that made it. When a hen eats a varied diet and lives well, the egg gets richer — more antioxidants, better fats, more of the vitamins and minerals your body is looking for. When she doesn't, you get the baseline.

We didn't set out to beat a spreadsheet. We set out to raise hens the way they ought to be raised, and then we checked our work. The lab agreed.

The next time you're standing in front of a wall of egg cartons that all look more or less the same, remember that the carton can't tell you what's inside. The lab can. And ours did.
