Heart & Soil was founded by Dr. Paul Saladino, MD, a board-certified physician and nutrition expert with a passion for ancestral health. Inspired by his medical training and a deep understanding of nutritional biochemistry, Dr. Saladino created Heart & Soil to reconnect people with the nourishing power of organ meats. His journey began with a mission to help others reclaim their health through nature’s most nutrient-rich foods, promoting vitality and strength by embracing the nose-to-tail approach.

The brand formulates its products using 100% grass-fed and pasture-raised organs sourced from regenerative farms in New Zealand and the United States. Each product is crafted to retain maximum nutrient bioavailability, delivering essential vitamins, minerals, and growth factors in their purest form.
