NutriSpec's Supplement Facts label maker generates FDA 21 CFR 101.36 compliant Supplement Facts panels for dietary supplements — vitamins, minerals, protein powders, herbs, amino acids, and probiotics. It supports all 6 FDA population-specific RDI tables (Adult, Children 1-3, Children 4-8, Pregnant, Lactating, Infant), handles dietary ingredient source declarations, proprietary blends, and proper units (mcg, mg, IU, CFU). Most online label tools only do Nutrition Facts — NutriSpec is one of the few covering Supplement Facts.

Each RDI table is sourced from FDA 21 CFR 101.9(c)(8)(iv) and applied automatically based on your product's target population.
Supplement Facts (21 CFR 101.36) is for dietary supplements; Nutrition Facts (21 CFR 101.9) is for conventional foods. Supplement Facts lists dietary ingredients with their source, allows zero amounts to be omitted, and uses different RDI tables. The header reads "Supplement Facts" — using "Nutrition Facts" on a supplement is an FDA violation.
For general adult supplements, use the Adults and Children ≥4 years RDI. For prenatal vitamins, select the Pregnant RDI. For children's products, select the appropriate age group (1-3 or 4-8 years). NutriSpec automatically applies the correct %DV based on your selection.
Yes. FDA 21 CFR 101.36 requires declaring the source of each dietary ingredient: "Calcium (as calcium carbonate)" not just "Calcium." NutriSpec handles this automatically — just enter both the nutrient and its source form.
Structure/function claims (e.g., "Calcium builds strong bones") are allowed under DSHEA with the mandatory FDA disclaimer: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." Health claims (disease-specific) require FDA pre-approval.
Yes. FDA 21 CFR 101.36(c) allows listing a proprietary blend's total weight and its dietary ingredients without individual amounts, followed by "† Daily Value not established." NutriSpec supports this formatting.
Yes. The Free plan includes 5 labels per month. Pro ($49/mo) gives you 50 labels. All 6 RDI tables and Supplement Facts formats are available on all plans.
