It is a plant-based protein source derived from Saccharomyces cerevisiae, a species of yeast commonly used in baking and brewing, it is then processed through controlled fermentation and extraction techniques to yield a concentrated protein source.The fermentation process helps improve amino acid availability and digestibility.
Yes. Yeast protein contains all 9 essential amino acids, making it a complete protein similar to whey and soy.
Yeast protein is dairy-free, lactose-free in nature, it is gentle on the stomach and is suitable for vegans. On the other hand whey protein is fast-absorbing in nature, it is dairy-based which might cause bloating in sensitive individuals. In short, yeast protein is ideal for people who cannot tolerate whey.
Unlike many plant proteins (pea, rice, etc.), yeast protein is a single complete protein source that has a better amino acid balance, is less gritty and easier to digest.
