Q&A Highlights - June 2025

About this video

In this June 2025 Q&A, Yurth discusses a study she cites linking living near a golf course with higher Parkinson’s risk, attributing concern mainly to pesticide exposure through air and groundwater, and suggests water filtration, checking local water data, and avoiding spray times. She presents progesterone as an under-discussed hormone for men, arguing it may support prostate, brain, sleep, and bone health. She explores research interest in oxytocin for bone density and muscle, plasmalogen precursors for brain tissue, and mitochondrial peptides she describes as supporting energy production. She also discusses nicotinamide in the context of skin-cancer history, and argues low NAD in humans may signal overactive depleting enzymes rather than being the root problem itself.

Key takeaways

• Reduce environmental exposure first with water and air filtration and timing around spraying
• Consider progesterone as part of a full hormone picture for men, not an afterthought
• Look upstream for why a marker like NAD is low instead of only replacing the marker
• Distinguish intriguing early research on oxytocin and plasmalogens from settled treatment
• Evaluate mitochondrial claims by whether membrane function and energy production plausibly improve
