Not JUST third-party tested. NSF Certified for Sport (aka a WAY stricter standard)
Supplements don’t need FDA approval before they hit the shelf. A company can print almost anything on the label and sell it. Nobody checks first.
A 2023 study in JAMA Network Open tested 57 sports supplements bought online. 89% didn’t accurately list what was in them. 40% had NO detectable amount of the ingredient on the label. And 12% contained ingredients the FDA prohibits.
So yeah. “Third-party tested” on a tub can mean pretty much anything.
NSF Certified for Sport means:
✅ What’s on the label is what’s in the tub (they verify the amounts)
✅ Screened for contaminants
✅ Tested for 270+ substances banned in pro sports
✅ The facility gets inspected on an ongoing basis. Not a one-time sticker.
USADA, MLB, and the NHL recognize it. Those athletes get drug tested. They can’t gamble on what’s in their scoop.
“But Alexa, I’m not a pro athlete.” Girl, neither am I 😂 But you’re paying for what’s on that label, so you should GET what’s on that label. Not a tub of BS with cute packaging. You’re drinking this every single day!
That’s why Opti-Greens 50 is the one I actually trust. NSF Certified for Sport, tastes like berries (NOT a lawn), and it’s been in my morning routine for 7years.
