We are in the position to offer three kinds of L-Lysine:


1 L-Lysine HCl 98.5% (Feed Grade)

2 L-Lysine Sulphate 65% (Feed Grade)

3 L-Lysine Sulphate 70% (Feed Grade)


Both are fermented from conventionally grown corn starch in China without any foreign materials added during the whole process:


1.The Difference:

1. L-Lysine HCl is highly purified to 98.5% after fermentation.

2. L-Lysine Sulphate, which is more cost-effective, is semi-purified and contains other fermentation by-products such as other essential amino acids and carbohydrate.

3. L-Lysine HCl 98% could attribute 78.4% free lysine and L-Lysine Sulphate 65%, equal to 65% lysine HCl, could provide 51% free lysine in the feed. L-Lysine Sulphate 70%, equal to 70% lysine HCl, could provide 55% free lysine in the feed.
