Summary
On this episode of Fitness Stuff, hosts Tony and Marianna break down the top 5 best and worst supplements, separating what is backed by research from what is pure hype. They dig into whey protein, creatine, magnesium, vitamin D, fish oil, and more to show which supplements actually deliver results, while also exposing the ones that fall flat like fat burners, detoxes, and overpriced greens powders. Along the way, they share a few honorable mentions from their own supplement stacks and explain why they use them. Fitness Stuff for Normal People is built on research, facts, and giving listeners the tools to make their own informed opinions about health and fitness.

| 1:24.1 | company. And we want to make it clear that they are not the only place you can get |
| 1:27.9 | good supplements out there. There are some niche products where other brands might do it better |
