Gero-Protective Drugs and Supplements
Recent research has identified several promising compounds that might extend lifespan and enhance health during aging. GLP-1 agonists like Ozempic, while currently known for their metabolic benefits, are being studied for potential anti-aging effects beyond their established uses. Similarly, SGLT-2 inhibitors show promise in improving cardiovascular health and kidney function, though their direct impact on longevity requires further investigation.
The episode also explores newer supplements in the anti-aging field. Methylene blue has attracted attention for its potential to enhance mitochondrial function and delay aging, though human evidence remains limited. Telomere lengthening supplements, including TA-65 and other telomerase activators, have generated interest in the anti-aging community, but current data on their effectiveness in humans remains inconclusive.
Cardiovascular Disease Prevention
Research indicates that daily low-dose aspirin plays a significant role in reducing the risk of heart attacks, strokes, and other cardiovascular outcomes. While studies continue to examine aspirin's full impact on lifespan, existing research suggests promising benefits in cardiovascular disease prevention.
Muscle Mass Interventions
Studies demonstrate that combining high-quality protein intake with resistance training effectively builds and preserves muscle mass throughout life. In addition, researchers are investigating follistatin gene therapy, which works by inhibiting myostatin, a protein that limits muscle growth. While this therapy shows potential for enhancing muscle development, it requires more comprehensive research to understand its full implications.

Actionables
- You can track your health markers by using a personal health dashboard app to monitor potential benefits of any new supplements or medications you decide to take under medical supervision. For instance, if you start taking a supplement that is believed to have anti-aging properties, you can log your biomarkers such as blood pressure, heart rate, and blood sugar levels before and after to see if there are any significant changes.
- Engage in a structured resistance training program at home or at a local gym to support muscle preservation, using bodyweight exercises or free weights as a starting point. Begin with simple exercises like squats, push-ups, and lunges, and progressively increase the difficulty by adding more weight or trying more complex movements as you get stronger.
- Create a meal plan that emphasizes protein-rich foods in combination with your workout routine to optimize muscle mass maintenance. Include a variety of protein sources such as lean meats, legumes, and dairy in your meals, especially after resistance training sessions, to aid in muscle recovery and growth.
