Product Information Zylkene Plus is a calming complementary feed product which combines two natural origin ingredients to offer a gentle, yet reliably effective way to help pets manage prolonged or recurring emotionally challenging situations. Zylkene Plus combines the natural origin active ingredients alpha-casozepine and white fish muscle hydrolysate. The effect of alpha-casozepine is based on the principle of satiety and sleepiness in new-borns after feeding on milk/colostrum. Hydrolysing white fish muscle yields bioactive peptides and amino acids that are considered to have calming properties.
