Frequently Asked Questions

NutriSaf® is a premium, non-diluted yeast fraction produced from a proprietary Saccharomyces cerevisiae strain. It provides highly digestible functional protein, essential amino acids, nucleotides, mannans and β-glucans, making it an excellent alternative protein source for livestock feeds and milk replacers. Its unique composition helps support digestive health, nutrient utilisation and animal performance, particularly in diets with high levels of plant-based ingredients or reduced animal-derived proteins.

Yes. NutriSaf® offers nutritionists a highly digestible functional protein source that can partially replace traditional specialty proteins such as spray-dried porcine plasma in piglet diets where regulations, supply or sustainability are considerations. Research has shown comparable support for feed intake and post-weaning performance while contributing valuable amino acids and functional yeast compounds. It also complements plant-based formulations by improving protein quality and diet functionality.

NutriSaf® is suitable for multiple livestock species, including pigs, poultry, calves, dairy and beef cattle, and is particularly valuable in milk replacers and young animal diets where highly digestible protein is essential. Its amino acid profile and functional yeast components also make it well suited to plant-based feed formulations across species. Published Phileo research additionally demonstrates excellent digestibility and gut-supporting properties in aquaculture, highlighting the versatility of this premium yeast protein ingredient.

Young animals have high nutrient demands but immature digestive systems, making protein digestibility critical. NutriSaf® supplies readily digestible yeast protein together with essential amino acids, nucleotides and functional yeast fractions that help optimise nutrient utilisation during early growth. These characteristics make NutriSaf® a valuable complementary protein ingredient for infant feeds, offering nutritionists greater formulation flexibility by improving ingredient cost efficiency while supporting feed intake, digestive health and the nutritional requirements of young animals.

Unlike many conventional yeast-extract ingredients, NutriSaf® is a premium, non-diluted yeast fraction containing 100% functional yeast material with no grain or inert carrier. This provides nutritionists with a highly concentrated source of digestible protein, essential amino acids, nucleic acids, mannans and β-glucans, delivering greater nutritional value per kilogram of ingredient. By maximising the proportion of functional nutrients, NutriSaf® enables more efficient formulation while supporting animal performance across multiple livestock species.
