AVELOR SUMMARY

Sake lees (sake kasu) is the fermentation byproduct of sake production, rich in resistant protein, alpha-glucosylglycerol, and fermentation metabolites. Japanese studies show blood pressure reduction (3-5 mmHg), improved skin moisture, and enhanced ceramide production. Very niche supplement category. Alpha-glucosylglycerol improves skin moisture by 46% (oral supplementation). Limited to Japanese research. Not widely available outside Japan. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
