BADASS FUEL — Fuel for Badass Women 

Scientifically Supported Ingredients | Support, Not Replacement | Non-GMO 

Two years ago, someone asked me what supplements I take to maintain my health, energy, and edge — and they were surprised that I only took four things consistently. For myself and my patients, there are four basics that support — at a foundational level — nearly every system in our bodies. In my quest for the highest quality ingredients and the easiest system for consistently incorporating supplementation into my routine, I formulated and manufactured my own line of foundational supplements. Trusted for myself and my patients, and under the guidance of your own healthcare provider, I’m excited to invite you to check out our foundational product line: Badass Basics. Learn more or order the products yourself by visiting!

“You see the best athletes in the world know about sleep; they know it’s good for performance. But, the sleep scientist will quickly tell you that they still struggle to actually get them to do it. That’s the missing piece … the application.” — Dr. Marc Bubbs 


“If you get a good night’s sleep and get yourself off to a good start … those big problems that you thought were big problems, now, all of a sudden, you’re [able to] cross … off of [your] list pretty quickly.” — Dr. Marc Bubbs 


“We always think … that [elite athletes] are just really disciplined. That’s why they get up at 5:30 [a.m.] and they go for their run. No, they’re cursing under their breath! … They just get up and do it. Ultimately, that’s what we’re trying to get to.” — Dr. Marc Bubbs
