Episode 456: Why Half Your Supplements Are Probably Useless (And Which 4 Actually Matter)

from Habits and Hustle · host Jen Cohen

Are you throwing money away on supplements that do nothing? In this Fitness Friday episode on the Habits and Hustle podcast, Liron Kayvan and I break down the supplement industry's biggest myths and reveal which ones are actually worth taking. We discuss why most supplements are unregulated snake oil, the importance of third-party testing, and how to cycle supplements so your body doesn't become desensitized. Plus, we share our personal supplement protocols and explain why getting blood work is non-negotiable before starting any regimen. Liron Kayvan founded BFLA in 2019. He’s a NASM Certified Group Fitness Instructor, Personal Trainer, and Transformative Life Coach. Liron has competed in Amateur MMA, Brazilian Jiu Jitsu, and Rugby and has been a Fitness Coach for over 10 years. What we discuss: Why supplements should be the smallest part of your health pyramid The lack of FDA regulation in the supplement industry Essential supplements: creatine, omega-3, vitamin D with K2, magnesium Why creatine isn't just for bodybuilders (new Alzheimer's research) The importance of third-party testing and NSF certification How to cycle supplements to prevent tolerance Why you need blood work before and after supplementation NAD and alpha-GPC for brain health Working with your natural patterns vs. fighting them The difference between giving energy vs. getting energy from exercise Thank you to our sponsor: Momentous: Shop this link and use code Jen for 20% off Therasage: Head over to therasage.com and use code Be Bold for 15% off  TruNiagen: Head over to truniagen.com and use code HUSTLE20 to get $20 off any purchase over $100.
