This made me curious so I checked the FDA site. In case anyone else is interested:<p>From a very cursory review, it appears that health claims on the packaging are quite heavily regulated by the FDA[1], but advertising for dietary supplements and foods seems to fall outside their mandate and regulatory responsibility lies instead with the FTC:<p><i>&quot;The Federal Trade Commission (FTC) regulates advertising, including infomercials, for dietary supplements and most other products sold to consumers. FDA works closely with FTC in this area, but FTC&#x27;s work is directed by different laws.&quot;</i>[2]<p>I&#x27;m not sure what&#x27;s on the bottle, but presumably the websites falls under the jurisdiction of the FTC. A brief review of their site seems to indicate a far more relaxed approach is taken. For example:<p><i>&quot;The FTC&#x27;s standard for evaluating substantiation is sufficiently flexible to ensure that consumers have access to information about emerging areas of science&quot;</i><p><i>&quot;These factors are often weighed together to ensure that valuable product information is not withheld from consumers because the cost of developing substantiation is prohibitive&quot;</i><p><i>&quot;...the FTC gives great weight to accepted norms in the relevant fields of research and consults with experts from a wide variety of disciplines, including those with experience in botanicals and traditional medicines&quot;</i> [3]<p>[1] <a href="http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;IngredientsPackagingLabeling&#x2F;LabelingNutrition&#x2F;ucm111447.htm" rel="nofollow">http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;IngredientsPackagingLabeling&#x2F;Labelin...</a><p>[2] <a href="http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;DietarySupplements&#x2F;QADietarySupplements&#x2F;#how_ad" rel="nofollow">http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;DietarySupplements&#x2F;QADietarySuppleme...</a><p>[3] <a href="https:&#x2F;&#x2F;www.ftc.gov&#x2F;tips-advice&#x2F;business-center&#x2F;guidance&#x2F;dietary-supplements-advertising-guide-industry" rel="nofollow">https:&#x2F;&#x2F;www.ftc.gov&#x2F;tips-advice&#x2F;business-center&#x2F;guidance&#x2F;die...</a>
