 Supplements work, but they take longer than you think. Took me about two years of supplementing to start seeing my deficiencies go away. So a lot of people take a supplement for like a month. They're like, I don't feel any better. It doesn't work quite like that, you know what I'm saying? My mom always says people run their body into the ground for 20 years and think they'll fix it in 20 minutes. Don't work that way. Number two, test your blood a lot. I've been testing my blood once a month for two years now. And I've learned a lot of stuff. One is that cortisol is a big deal and you have to get your stress levels down. You can't really optimize your body without optimizing stress reduction. The third one is 18-minute nap. You wanna change your life, take a nap every day.
