Smartamine® MAX
The new standard in rumen-protected methionine
When results matter, MAX matters most.
The new standard in rumen-protected methionine
Methionine
The best legacies don’t end,
they evolve.
Built on the trusted Smartamine legacy
For more than 30 years, Smartamine® M has set the benchmark for reliable methionine delivery and consistent results, supported by extensive scientific research and used in the diets of 2.5 million cows worldwide. Smartamine® MAX builds on that legacy.
Smartamine MAX combines two patented technologies: a unique methionine core formulation and a pH-sensitive, biopolymer-based coating that protects methionine through the rumen and enables targeted release for absorption.
Smartamine MAX at a glance
Engineered, tested, and refined
over five years to set a higher standard
In vivo evaluations at the University of New Hampshire (UNH) guided the development and refinement of Smartamine MAX to deliver 64% metabolizable methionine (mMet; Graph 1).

Rigorous quality control
in every industrial batch
Smartamine® MAX undergoes a rigorous three-step quality control process to ensure consistent delivery of metabolizable methionine. Our proprietary laboratory methods are calibrated against bioavailability measurements in lactating cow trials at UNH and verify each critical specification.
Every batch must pass all three steps before it is released for sale.
Each batch is verified to contain a minimum of 80% DL-Methionine.
Verified using validated proprietary lab methods. Only batches meeting the protection spec are released, ensuring consistent rumen bypass.
Verified as a proxy for abomasal release, so methionine is released where the cow can absorb it.

When product specifications overestimate mMet delivery, the cow receives less than you formulate for, creating a gap that can limit expected performance (and result in money wasted).
