Safety & Side Effects: What U.S. Parents Should Know Before Choosing a Growth Supplement
If you're like most parents I’ve talked to over the years—especially those messaging me through NuBest Nutrition—you probably care just as much about what goes into your kid’s body as what it might help them grow out of. And trust me, I get it. My own nephew took a growth supplement for a year, and I triple-checked every label before he ever popped a capsule.
Here’s what you should know when it comes to NuBest vs. standard calcium-only supplements, especially from a safety-first standpoint:
NuBest Tall is manufactured in an FDA-registered facility and follows GMP (Good Manufacturing Practices). That’s not just a fancy badge—it’s a baseline requirement for any supplement I’d let a teen near.
It’s also NSF Certified, which is huge. That means it’s been independently tested for purity and label accuracy. Not all supplements go through that.
No major side effects have been reported in U.S. reviews (I’ve personally gone through dozens on Amazon and on our customer feedback channel). The most common issue? Mild stomach upset if taken on an empty stomach—easily avoided.
Compare that to generic calcium pills, which can cause constipation or, if overused, even kidney strain. Yep, too much calcium is a thing—especially when parents double-dose unknowingly.
Pediatricians I’ve interviewed (and there’ve been a few over Zoom) usually greenlight NuBest Tall for kids over 5, but still recommend checking with your child’s doctor—especially if they’re already on meds or multivitamins.
