Smartamine® MAX
The new standard in rumen-protected methionine
When results matter, MAX matters most.
(640 g/kg)
The best legacies don’t end, they evolve.
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
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), above the 60% industry benchmark.

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

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.
≥ 80%DL-Methionine
Each batch is verified to contain a minimum of 80% DL-Methionine.
How it’s tested
Grinding of Smartamine MAX
Extraction of methionine
Separation and UV quantification at 205 nm
> 94%Protection rate
Verified using validated proprietary lab methods. Only batches meeting the protection spec are released, ensuring consistent rumen bypass.
How it’s tested
Beadlets placed in a buffer solution (pH 6.0, 40°C for 4 h)
Analysis of the supernatant solution
Separation and UV quantification at 205 nm
OptimalBiopolymer content
Verified as a proxy for abomasal release, so methionine is released where the cow can absorb it.
How it’s tested
Chitosan content in the coating is tightly controlled to defined specifications for every batch.
Coating rate is controlled through in-process analytical checks for both protection and release performance.

Contact Our TeamA dedicated production line
Smartamine MAX is produced exclusively at Adisseo’s Commentry facility in France.
A dedicated coating-solution production line was built alongside the existing Smartamine® M line, so every batch of Smartamine MAX is made to its own specification, with the same manufacturing expertise behind it.
