Story at a glance:

Proposed legislation is calling for a federal database for dietary supplements, which requires supplement makers to submit information to the U.S. Food and Drug Administration (FDA).

Known as mandatory product listing (MPL) for dietary supplements, supporters claim it's a way for the FDA to know what products are on the market and what ingredients they include.

Opponents suggest the move, which is redundant and burdensome for small supplement companies, could ultimately give the FDA more power to ban supplements from the market.

MPL could pave the way for the FDA to gain premarket approval power — changing access to supplements as we know them.

Multinational companies like Bayer, Nestle, Unilever, Proctor & Gamble and Clorox have also been buying up supplement companies at a frenzied pace. In 2018, there were 83 such transactions; this rose to 137 in 2021.
