How does ReguSift handle proprietary blends under FDA rules?

ReguSift uses AI to extract product data and prepare Nutrition Facts and Supplement Facts drafts for review against the source specification.

A proprietary blend declares its total weight and lists applicable constituents in descending order by weight. Do not calculate a combined blend %DV from those constituent weights. Ingredients with an established Daily Value require the applicable separate declaration. Read 21 CFR 101.36(c).
