This week on Stronger Weekly, I’m joined by Connor Shehan, VP of Nutrition at Rep Fitness and architect of Purist Nutrition, to break down the truth behind supplement quality. Connor explains what “pure” really means, why the supplement industry is so hard to navigate, and how to read labels without getting misled by marketing.

He also outlines the biggest red flags, the risks of contaminated or poorly tested products, and the principles Purist uses to build formulas that actually meet high standards for purity and transparency. He also gives his recommendations on the essential supplements that EVERY person should take if they're serious about their fitness.

Plus, we cover this week’s Health & Fitness News:

Smartphones at 12 linked to worse mental & physical health – A major NIH analysis reported by Axios found that giving kids a smartphone at age 12 predicts higher rates of depression, obesity, and poor sleep through adolescence — even after adjusting for income, home environment, and screen time on other devices.

CDC panel votes to end universal Hepatitis B shot at birth – The CDC’s advisory committee moved toward dropping the long-standing recommendation that all newborns receive a Hep B shot, raising concerns about missed infections if hospitals rely solely on maternal screening and perfect follow-up.

Vigorous exercise packs the same punch as much longer cardio– A Nature Communications study of 73,000 adults found that just one minute of vigorous effort can deliver the same long-term health benefit as 4–9 minutes of moderate activity or nearly an hour of light movement.

Jump-rope warm-ups improve running performance – A 10-week trial in the International Journal of Sports Physiology and Performance found that swapping five minutes of a standard warm-up for jump rope improved reactive strength, running economy, and amateur 3K race performance.

Weekly Weird News: Rotten-egg gas shows promise for Alzheimer’s – Johns Hopkins researchers found that hydrogen sulfide restored a key cellular process in Alzheimer’s mouse models, improving memory and motor function and pointing toward unconventional low-dose therapies.

If you're looking to clean up your supplement routine—or finally understand what “purity” means in an industry with almost no guardrails—this conversation gives you a simple, science-backed framework to make better decisions.
