This site states this specific category-wide fact directly: no dietary supplement is FDA-approved, as the agency explains on its dietary supplements page.
Worth reading this as applying to every dietary supplement on the market, not a specific shortcoming of this particular spray — a useful, broader piece of regulatory context.
This site separately states GMP certification is not the same as FDA approval — worth reading both statements together as this site's consistent, precise regulatory framing throughout the page.
