Open questions

Yeast protein has slightly lower bioavailability than whey protein.

Limited evidence · What we still need: Independent third-party studies are needed to quantify the exact difference in bioavailability compared to whey and its practical implications for muscle protein synthesis.

Yeast protein is one of the most sustainable protein sources.

Limited evidence · What we still need: Seek independent environmental impact assessments, certifications, or detailed comparisons with other protein sources to verify sustainability claims.

Long-term consumption effects and user experience.

Limited evidence · What we still need: More extensive long-term user reviews and independent studies on the sustained benefits or potential drawbacks of yeast protein are needed.
