@thebeautydoctrine: Mitochondria matter 🧬 MUSCLE OVER COLLAGEN, Part 5: Urolithin A We've talked about building muscle and protecting muscle. Now let's talk about the mitochondria inside your muscle. Urolithin A is a fascinating longevity molecule because it's being studied for mitophagy, the cellular quality control process that helps identify and clear dysfunctional mitochondria. Your body can produce urolithin A from compounds found in foods like pomegranates, but production varies considerably between people because it depends on the gut microbiome. And we now have randomized human trials. In middle aged adults, four months of urolithin A supplementation improved measures of muscle strength and produced changes in biomarkers associated with mitochondrial health. In another trial of adults 65 to 90, researchers found improvements in muscle endurance and mitochondrial biomarkers, although not every primary endpoint improved significantly. That's an important distinction. I'm interested in urolithin A because of the emerging human evidence around mitochondrial quality and muscle function, not because it's a miracle muscle builder. My muscle longevity strategy keeps expanding: Resistance training → Protein → Creatine → Leucine → HMB → Mitochondrial support Because preserving muscle isn't only about how much muscle you have. It's also about how well that muscle functions. MUSCLE OVER COLLAGEN. As with any supplement, individual needs and medications matter. Speak with your healthcare professional if you're unsure whether supplementation is appropriate for you. #UrolithinA #WomenOver40 #timeline #HealthyAging #Longevity
