The Federal Trade Commission has been increasingly aggressive in enforcing health claim standards over the past three years, and the regulatory posture in 2026 is meaningfully tighter than what brands faced in 2022 or 2023. International brands entering the US dietary supplement and functional product categories need to understand that the claim standards are not optional, and the enforcement is real.

The core FTC standard is that any health related claim must be supported by competent and reliable scientific evidence. The agency has clarified what that phrase means in practice. For most health claims, the standard is two well designed human clinical trials, conducted on the product or its active ingredient, in the relevant population, at the dosage being claimed.

This is a substantially higher bar than what many international brands assumed. A claim supported by mechanism of action studies, animal studies, or single human trials may not meet the FTC standard, even if the claim is technically accurate. The standard is about adequacy of evidence in the eyes of the FTC, not about scientific truth in a broader sense.

The enforcement actions the FTC has brought in recent years have shifted the cost calculation for brands considering aggressive claims. Settlement amounts in the multi million dollar range, mandatory consumer refunds, and bans on category specific advertising have all become standard outcomes. The carrying cost of a claim that fails FTC scrutiny is not a redrafted label. It is a substantial financial liability and a brand reputation hit that takes years to recover from.

The fix is to build your claims architecture from the evidence backward, not from the desired messaging backward. Start with what your science actually supports. Map each claim to the studies that support it. Have your claims reviewed by FTC compliance counsel before they ever appear on packaging, advertising, or your website. And maintain a substantiation file that documents the basis for every claim in case the FTC ever asks.

The brands that get this right protect their ability to make claims for years. The brands that take shortcuts lose the ability to make any claims at all, which is a far worse business outcome than the conservative claims architecture they should have built in the first place.
