ISSUE FOCUS 56 FEED & ADDITIVE MAGAZINE May 2024 Vitamin E (or even C). However, not all polyphenols are equally bio-available nor evenly bio-effective inside animal body cells. ELIFE®, a blend of selected botanical extracts rich in short-type polyphenols, is a potent antioxidant equivalent to synthetic Vitamin E in the animal. This claim has been demonstrated in multiple researches using bio-relevant lab models, such as direct oxidative challenges to animal gut epithelial cells. Thanks to its high antioxidant capacity in such biological matrices, ELIFE® allows a reliable replacement of Vitamin E acetate 50% ADS. This translates into an efficient 1:2 dosage ratio and a safe substitution rate (depending on the initial Vitamin E level in the diet). In combination with its low cost per kg of VE50 ADS. equivalence, the product has proven to create interesting financial savings for formulators. Sources 1Ayuso et al. (2020).
