EFA-50® belongs to the line of nanoencapsulated chemicals, and in this case formic acid is encapsulated in a hydrogenated fat matrix. This encapsulation meets superior capabilities to improve the effectiveness expected from the incorporation or organic acids. Our wide knowledge in the field has allowed us to develop an encapsulation process that releases the main components at different parts of the gastrointestinal tract.

Therefore, EFA-50® contains a set of three versions depending on the part of the digestive tract to be targeted.


EFA-50® is suitable for use in:



The encapsulated formic acid provides several properties to the feed safety: there is a microbial decontamination and protection of feed, a clear increase in animal performance (weight gain, feed conversion ratio…) and a reduction of bacterial contamination entering in the human chain.

Other benefits can be summarized as:

  • Enhanced gastrointestinal health.
  • Improvement of feed efficiency and protein, fat and mineral digestibility. 
  • Good effect at low inclusion.
  • Safe and easy to handle.
