How I Choose a Protein Powder at the Store (And Why It Matters)
Protein has been a daily constant in my life. First as a founder building nutrition products, and now as part of my longevity and muscle-preservation strategy.
What many people don’t realize is that not all protein powders are equal. Some contain trace heavy metals like lead or cadmium; not because brands are careless, but because plants absorb what’s in the soil, and concentration amplifies it.
When I was building thinkThin®, I learned early that better questions change outcomes. That mindset still guides me. If I’m standing in the store, here’s how I decide:
I turn the container around first, then read ingredients before the claims. Fewer is better. If I see gums, artificial sweeteners, or proprietary blends, it goes back.
Third-party testing is non-negotiable. NSF, USP, Informed Choice, or clear batch testing for heavy metals. If it’s not visible, I assume it’s not happening.
I check the protein source. Grass-fed whey or clearly sourced plant proteins. “Globally sourced” isn’t enough.
I’m cautious with flavored powders. Chocolate and heavy flavoring often mean more additives. I choose unflavored and customize.
Protein per serving matters. 20–25g per scoop, no added sugar or fillers.
Do I trust the brand? Good brands welcome scrutiny.
Protein should support muscle, blood sugar, and cellular repair, not quietly add toxic load. Longevity isn’t about more supplements. It’s about smarter daily inputs.
Clean protein is foundational.
To your vitality,
