About the Formulator
Seventy years of animal health in every bottle.
Dr. Harman is a PhD nutritionist whose career spans more than seven decades of research, field work, and innovation in livestock health. His tonic is not a product of a lab — it is the product of a lifetime's experience.
A lifetime of conversations with cattle producers.
Dr. Harman's work in animal health began more than seventy years ago — long before "integrative livestock nutrition" was a phrase anyone used. He spent those decades in the field, in the lab, and in conversation with the producers who were losing cattle to parasites they could barely see and barely understand.
Those conversations shaped everything. Producers described animals that looked fine until they didn't. Livers condemned at slaughter. Calves that never gained the way they should have. The economic losses were real, and the tools available were limited. Dr. Harman believed there was more that could be done — not to replace conventional treatment, but to support the animal's own biology during the seasons when fluke pressure was highest.
The result is a nutraceutical liquid tonic formulated to support liver health, promote bile flow, and create a less hospitable environment for flukes — administered as a drench during the high-risk windows of fall, winter, and spring. It is the product of a career spent listening to cattle and to the people who care for them.
"These products were developed and inspired by years of conversations with producers. His dedication to cattle health is unmatched."— On Dr. Harman's approach to formulation
Across his career, Dr. Harman has been granted 41 patents — a record that reflects not a single breakthrough but a sustained commitment to solving real problems in animal nutrition. His work spans mineral supplementation, digestive health, immune support, and parasite management. The liver fluke tonic is one expression of that body of work, brought to market because the need is real and the science is sound.
He does not believe in silver bullets. He believes in integrated management — strategic treatment, sound nutrition, good pasture practice, and products that support the animal's biology rather than simply overriding it. That philosophy is built into every aspect of how this tonic is formulated and how it is meant to be used.
Every ingredient in the tonic is chosen for a documented role in liver health, bile function, or parasite resistance — not tradition alone.
Formulated through decades of direct engagement with beef cattle producers across fluke-prone regions.
Designed to complement conventional flukicide treatment and pasture management — not replace them.
Cattle health that works with nature.
Dr. Harman's mission has always been simple: give producers tools that actually work, grounded in science, and honest about what they can and cannot do. The liver fluke tonic is not a cure. It is a support — a way to keep the liver functioning well during the seasons when fluke pressure is highest, so that animals can respond better to treatment and recover faster.
That honesty is the brand. No exaggerated claims. No shortcuts. Just a product that does what it says, from a formulator who has spent a lifetime earning the right to say it.
