If you’re trying to feel better, build longer, and avoid quietly poisoning yourself along the way, this episode’s for you.

After a run of injuries, weird labs, and a “half-man/half-plastic” toxin screen, I went deep on cleaning up my life. Enter: Justin Mares, founder/operator (Kettle & Fire, Perfect Keto, Surely, Truemed), and meticulous health nerd who has spent hundreds of hours testing what’s actually worth buying.

In this episode, we walk through Justin’s guide for safer, higher-quality living so you can stay healthy, perform your best, and continue to build amazing products.

In this episode, you’ll learn:

• The 80/20 of great sleep (and why temperature control and magnesium often matter most)

• What to wear (and avoid) to reduce PFAS, phthalates, and dye exposure on skin

• A sourcing playbook for nutrient-dense, low-toxin food

• Supplements that you actually need and why

• Practical toxin-mitigation at home: air, water, lighting, EMFs, kitchens, and cleaning

• Low-effort swaps for everyday products (deodorant, soaps, skincare, blue-light blockers)
