Q&A Highlights July 2025

About this video

In this July 2025 Q&A, Yurth argues antioxidants are widely overused, revising the old free-radical theory: reactive oxygen species, she says, are needed signals for mitochondrial adaptation and exercise benefits, so constant high-dose use, especially around training, can backfire. She reviews evidence she cites against arthroscopic surgery for degenerative meniscus tears, favoring conservative, inflammation-focused and regenerative approaches except in specific cases. She discusses topical GHK-copper and a tissue-matrix wound product for scars and wounds, a supplement aimed at the endothelial glycocalyx, and creatine as an energy-buffering support for both muscle and brain. She closes by presenting SGLT2 inhibitors alongside GLP-1 medicines as emerging longevity tools, while noting access and cost barriers.

Key takeaways

• Use antioxidants intermittently and strategically, not as a constant blanket around exercise
• Question surgery for degenerative meniscus tears and address inflammation first
• Consider creatine for brain energy demands as well as for lifting performance
• Evaluate SGLT2 inhibitors, in her framing, by metabolic and organ effects beyond glucose
• Separate a plausible wound or vascular supplement from proof it works in you
