What is fermented yeast-derived protein isolate? (JirehProTM )
A complete, vegan protein derived from yeast organisms like Saccharomyces cerevisiae using biofermentation. It is as effective as whey, without the dairy or bloating. Fermented yeast-derived protein isolate is naturally free of allergens like lactose, gluten, dairy and soy. JirehPro offers great nutrition and planet sustainability, leaving no carbon footprint.
Is fermented yeast-derived protein isolate safe to use everyday?
Yes. Yeast itself has been used for centuries to make from sourdough to kombucha.
Nowadays we have yeast-derived protein isolate that can be used daily after your workout, or whenever you need to increase the protein content of any meal with a clean source of easily digestible protein.
Ummmm….I’m concerned about the “yeast” part…Does Yeast-derived Protein Isolate contain any yeast in the final protein product?
No. Yeast-derived Protein Isolate does not contain whole yeast cells in the final product; it is an isolated protein derived from the Saccharomyces Cerevisiae yeast strain after a fermentation and processing stage.
The processing includes an extraction and purification stage which removes or partially removes the non-protein components like fats and polysaccharides, leaving a high-purity protein isolate.
This process makes Yeast-derived Protein Isolate a vegan, allergen-free, and gut-friendly, neutral flavour protein that is easy to digest.
JirehProTM How good is fermented yeast-derived protein isolate really?
It is EXCELLENT! Fermented yeast-derived protein isolate is a complete protein with all 9 essential amino acids, a PDCAAS of 1.0/1.0 (just like whey), and zero allergens. It’s easier to digest, more sustainable, and helps you build and recover muscle, minus the challenges of dairy.
What does PDCAAS of 1.0/1.0 mean?
PDCAAS stands for Protein Digestibility-Corrected Amino Acid Score — it’s the gold standard in measuring how well your body can use a protein. 1.0 is the highest possible score, meaning all 9 essential amino acids can be fully absorbed in the right balance. JirehProTM scores 1.0, same as whey.
How does the amino acid profile of JirehProTM protein bio-fermented compare to whey and other animal proteins?
Bio-fermented protein is on par with animal proteins, including whey, when it comes to its amino acid profile, containing all nine essential amino acids your body needs for muscle building and repair. With a PDCAAS score of 1.0, it’s nutritionally complete, offering the same muscle-building benefits as animal proteins, including whey.
The standout difference is in digestibility and sustainability. JirehProTM is easier on the body, free from allergens, and doesn’t come with the environmental cost of traditional whey and other animal proteins. It’s the ideal protein for those looking to build muscle while making a conscious choice for their health and the planet.
