I spent fifteen years in dietary supplement compliance. I co-founded Vital Proteins, sat through FDA audits, wrote CAPAs after Form 483s, and told a lot of founders things they didn’t want to hear about their marketing copy. The pattern was usually the same: the claims were too aggressive, the evidence was thinner than the team believed, and by the time anyone asked a serious question, the budget for answering it was already gone.
The real work of substantiating a claim is tedious: searching the literature, grading studies, cross-checking the regulation, writing up what you found. Most brands skip it, and not because they want to cut corners. Doing it properly across a full product line is just too expensive to justify.
SubstantiatePro is the tool I wish I’d had fifteen years ago. It does the tedious part quickly, ties every answer back to the actual regulation, and leaves you with a record you can hand to a regulator, a retailer, or your own legal team. It won’t replace your lawyer, but it will make their job a lot easier.
Regulatory scrutiny on supplement claims is only going up. The brands that can show their work are going to be fine. This is the tool for showing it.
