Our Story →
Wagyu beef's unique fat composition delivers measurable nutritional advantages. High oleic acid content, omega fatty acids, and CLA — the same healthy fat profile found in olive oil, supported by peer-reviewed research.
Carlog genetics are bred specifically to maximize these traits, not just marbling scores.
