Just wanted to share this…. stumbled upon an extract called maizinol….. derived from corn. Has some pretty impressive effects for increasing deep sleep by up to an extra 30 minutes a night over the course of a few weeks which is pretty astounding. here’s the pubmed links if anyone is interested https://pmc.ncbi.nlm.nih.gov/articles/PMC12759108/ https://pmc.ncbi.nlm.nih.gov/articles/PMC9889011/ Interestingly it looks like cvs brand has the only product i could find that only has maizinol as the sole ingredient it’s called “deep sleep support” . Please chime in if anyone has tried this for sleep
