The Health Interventions Actually Worth Your Time | Justin Mares

Podcast cover

The a16z Show

Effective health optimization relies on high-quality sourcing and consistent, sustainable habits rather than extreme, unproven interventions. Prioritizing circadian rhythm through morning sunlight, maintaining a nutrient-dense diet rich in ancestral proteins like bone broth and organ meats, and minimizing exposure to processed seed oils and environmental toxins form the foundation of a proactive health strategy. Regular blood work and targeted supplementation—such as natokinase for cardiovascular health and methylated B vitamins for metabolic support—enable data-driven adjustments. Justin Mares, CEO of Truemed, advocates for shifting healthcare spending toward these preventative lifestyle interventions. By leveraging HSA and FSA funds, individuals can invest in exercise, nutrition, and sleep aids, effectively addressing chronic disease at its root rather than solely managing symptoms within a reactive medical system.
