Tagging fillers in supplements?

About 99% of supplements have garbage in them like seed oils, starch, citric acid or other fillers because most people are too ignorant to read the ingredients labels, let alone realize that ultra-processed pseudo-food is harmful for them in the first place. I wonder if there is some tag for a nutrition supplements store to state that they offer clean supplements with just one ingredient, just like vegetarian tags, except focused on health rather than ethics. Maybe diet:raw=* could somewhat apply?
