Betaine Anhydrous 98%
High-purity betaine anhydrous — efficient methyl donor and osmolyte.
Our flagship betaine grade: ≥98% anhydrous with low trimethylamine residue — the most inquired specification for export premix and integrator customers.
Betaine anhydrous (trimethylglycine) is a highly efficient methyl donor that partially replaces methionine and choline in feed, supplying active methyl groups for the synthesis of proteins, nucleic acids and other vital substances. As a natural osmolyte it also protects intestinal cells under heat stress and coccidiosis challenge.
By supporting carnitine and phosphatidylcholine function, betaine takes part in fat metabolism — reducing fatty liver incidence, increasing lean meat percentage, and improving meat color, flavor and water-holding. In aquaculture it acts as a feed attractant and improves survival. Our most inquired grade: ≥98% purity with low trimethylamine residue.
Key Benefits
- ✓ Efficient methyl donor — partially spares methionine and choline chloride
- ✓ Natural osmolyte: relieves heat stress and protects intestinal epithelial cells
- ✓ Supports fat metabolism — less fatty liver, higher lean percentage, less drip loss
- ✓ Feed attractant in aquaculture; improves feed intake and survival
- ✓ Low residual trimethylamine; free-flowing, non-dusting powder
- ✓ Does not affect dietary electrolyte balance (dEB) or vitamin potency
