Check Latest PriceA dairy-free, soy-free, and lactose-free protein powder built for people whose stomachs don't get along with whey. Each scoop delivers 25g of complete protein and 6.7g BCAAs, sourced from fermented Saccharomyces cerevisiae yeast — the same yeast species used in baking and brewing, put through controlled fermentation to boost digestibility and amino acid availability. Comes in flavours like Cold Coffee and Rich Chocolate Crème, with added digestive enzymes so nothing sits heavy.
Most protein powders force a trade-off: whey works fast but can bloat sensitive stomachs, while many plant proteins (pea, rice, soy) are incomplete on their own and need blending to cover all essential amino acids. Nutrabay's Fermented Yeast Protein sidesteps both problems. It's a single-source complete protein — all 9 essential amino acids in one scoop — made allergen-conscious from the ground up, with no soy, gluten, or lactose in the mix.
The fermentation process is the real differentiator. By fermenting the yeast before extraction, Nutrabay makes the protein easier for the body to break down and absorb, which is where the "gut-friendly" claim comes from. Add in a built-in digestive enzyme blend (amylase, protease, lipase, lactase, and cellulase) plus a dose of probiotics, and the formula is designed to work with your digestion rather than against it.
