How do I calculate Daily Value percentages?
ReguSift uses AI to extract product data and prepare Nutrition Facts and Supplement Facts drafts for review against the source specification.
Daily Value (DV) percentages are calculated by dividing the amount of a nutrient per serving by the FDA-established Daily Value for that nutrient, then multiplying by 100.
For example, if a serving contains 60 mg of Vitamin C and the DV is 90 mg: (60 ÷ 90) × 100 = 67%.
ReguSift auto-calculates DV percentages based on current FDA reference values. See the step-by-step guide.
