EVONIK has announced the launch of a new guanidinoacetic acid-product (GAA), used to enhance energy metabolism in livestock production.

Branded GuanAMINO, the supplement is used to enhance energy metabolism in livestock production and is particularly crucial in broiler and pig production.

The launch comes close to two years after a former GAA supplier terminated its agreement, though Evonik continued to supply its customers beyond the end of 2018.

The end of that agreement prompted the firm to develop its own product.

GuanAMINO offers farm animals with the natural creatine precursor GAA, which supplies creatine to animals, improving their performance, ensuring optimal nutrient utilisation and therefore return over feed costs, Evonik said.


Creatine is vital for vertebrates as it contributes to ensuring that high energy demanding cells (particularly muscles) are supplied sufficiently.

In the body, creatine is formed through methylation of GAA, which itself is formed from the amino acids glycine and arginine.

However, in fast-growing animals, it is estimated that the body’s synthesis covers about two-thirds of the required daily need for creatine. A feed additive must supply the rest.

‘Major milestone’

Evonik Animal Nutrition’s Torben Madsen said: “We are proud to achieve this major milestone on our continuous way to provide our customers the best solutions for their individual needs.

“With GuanAMINO, we offer our customers the best creatine source and therefore, another performance-enhancing solution in our portfolio for sustainable, animal protein-free diets.”
