The figures below come from third-party laboratory testing arranged through the Bionutrient Food Association with Edacious, a public benefit corporation specializing in food composition research. Six Carter Country ribeye samples were analyzed and compared against retail and USDA benchmark data. Figures are specific to those tested samples; newer per-product results (July 2026, van Vliet lab at Utah State University) are noted where relevant - nutrient values shift with season and product.

A Deeper Look at What's in the Beef

The Bionutrient Food Association / Edacious analysis found that the tested Carter Country beef contained significantly higher levels of several key nutrients than the conventional comparison samples - and it looked far deeper than a standard label panel, identifying 48 different fatty acids.

Omega-3 Fatty Acids

The tested Carter Country ribeye measured 3.25 times the omega-3 fatty acids of the USDA benchmark and 2.13 times the retail beef ribeye comparison. Key omega-3s measured per serving:

• EPA (Eicosapentaenoic Acid): 13.548 mg (range: 11.598-17.035 mg)
• DHA (Docosahexaenoic Acid): 1.067 mg (range: 0.913-1.270 mg)
• Alpha Linolenic Acid (ALA): 0.067 g (range: 0.049-0.119 g)

Omega-3s are essential fats the body cannot make on its own. They support brain function, cardiovascular health, and a healthy inflammatory response.

Beneficial Compounds Often Missing from Conventional Beef

• Rumenic Acid: 12.428 mg - a beneficial form of CLA with anti-inflammatory properties
• Conjugated Linoleic Acids (CLA): 15.668 mg total - linked to improved body composition
• Pentadecanoic Acid: 0.058 g - associated with metabolic health
• Heptadecanoic Acid: 0.133 g - linked to reduced cardiovascular risk

The Critical Omega 6:3 Balance

One of the study's most significant findings was the omega 6:3 ratio of the tested samples:

• Carter Country ribeye (Bionutrient Institute, first test): 1.2:1
• Retail beef ribeye: 9.0:1
• USDA beef ribeye: 13.2:1

Our July 2026 product testing tells the same story across the lineup: 1.43:1 for the ancestral blend, 1.82:1 for ground beef, and 2.03:1 for tallow. The ratio shifts with season and product - greener grass lowers it, browner grass raises it - but it consistently lands near the roughly 1:1 to 4:1 range researchers associate with ancestral diets. The standard American diet typically runs between 15:1 and 20:1, a balance associated with chronic inflammation.

Mineral Content and Bioavailability

Mineral analysis across the six tested samples, compared with the retail and conventional benchmarks:

• Iron: 3.484 mg (range: 2.388-6.850 mg) - 61% higher than the retail comparison
• Calcium: 12 mg (range: 3-20 mg) - 92% higher than the retail comparison
• Potassium: 453.1 mg (range: 355.0-739.8 mg) - 15% higher than the conventional benchmark
• Zinc: 6.24 mg (range: 4.28-10.63 mg) - 16% higher than the retail comparison
• Selenium: 19.21 mcg (range: 10.23-32.78 mcg) - 43% higher than the retail comparison

The heme iron advantage: the iron in beef is heme iron - the most bioavailable form, absorbed at roughly 15-35% versus 2-20% for plant-based or synthetic supplement iron. That absorption difference matters as much as the raw number.

Heavy Metal Screening

Edacious testing of the Carter Country ribeye samples found arsenic, cadmium, mercury and lead below the limit of quantification, while the retail comparison sample carried measurable amounts of all four. Our July 2026 ground beef sample, tested by the Van Vliet Lab, likewise showed no detectable arsenic, barium, cadmium, nickel or lead.

Nutritional Efficiency: More from Less

The study's numbers allow a simple equivalency: to match the omega-3 content of 16 ounces of the tested Carter Country beef, you would need roughly 52 ounces of the retail comparison beef or 68 ounces of the USDA benchmark - along with the extra 3,200-4,200 calories and saturated fat that come with eating three to four times the volume. Nutrient density means getting more of what matters from a normal serving.

What This Means for Your Family

In the tested samples, Carter Country beef delivered:

• 3.25x the omega-3s of the USDA benchmark
• An omega 6:3 ratio between 1.2:1 and 2.03:1 across every sample tested to date, most recently 1.82:1 in our July 2026 ground beef
• 61% more iron and 92% more calcium than the retail comparison
• Arsenic, cadmium, mercury and lead below the limit of quantification
• 48 identified fatty acids, including beneficial compounds largely missing from conventional beef

Whole-food nutrition at this density can also mean leaning less on isolated supplements - the nutrients arrive together, in the forms and ratios the body absorbs best. As always, talk with your own health provider about what's right for your family.

Every meal is a chance to feed your family well. Choosing beef this nutrient-dense is one of the simplest ways to do it.

This analysis is based on nutritional testing conducted through the Bionutrient Food Association with Edacious. July 2026 per-product results are from the van Vliet lab, Center for Human Nutrition Studies, Utah State University.

Where this sits today

Across our beef products, every sample tested to date has measured between 1.2:1 and 2.03:1 omega-6 to omega-3, against 8.28:1 for grain-finished beef in a 2026 Journal of Animal Science study. The figures on this page are the specific samples and dates named above. Our most recent test, July 2026 ground beef, measured 1.82:1. Current results by product live on our nutrient testing page.
