Fermented yeast protein is a non-dairy protein made by growing yeast through controlled fermentation and then isolating the protein. Fizinga Smart Protein uses isolate fermented yeast protein in three 1 kg flavours and convenient 8-sachet trial packs.
What is fermented yeast protein?
Fermented yeast protein is protein produced from yeast through fermentation, rather than from milk, soy or peas. The resulting protein ingredient can be used in powders and ready-to-mix sachets. Fizinga Smart Protein is vegan and non-dairy, with no added sugar.
How is fermented yeast protein different from whey?
The main difference is the source. Whey comes from milk. Fermented yeast protein comes from yeast grown through fermentation. People who prefer a vegan or non-dairy protein may choose fermented yeast protein, while people who consume dairy may also use whey. The right choice depends on dietary preference, flavour and how each product fits a daily routine.

Fermented yeast protein may suit adults who want a vegan, non-dairy protein powder or who prefer an alternative to milk-derived whey and common plant-protein blends.
