Supplement Facts panel generator software: building 21 CFR 101.36 panels automatically

'Supplement Facts panel generator' is a common search for a reason: the panel is fiddly, rule-bound, and easy to get wrong by hand. But many free generators just draw a formatted box around numbers you type in — they don't know the rules. Real panel software builds a compliant 21 CFR 101.36 panel from the formula itself.

A box drawer is not a panel generator

The difference matters. A tool that lets you type values into a pre-styled template will happily produce a beautiful, non-compliant panel — wrong order, wrong units, outdated Daily Values, incorrect rounding. A real generator applies the 21 CFR 101.36 rules: the mandated nutrient order, the correct units, the dividing line for ingredients without a Daily Value, and the prescribed rounding.

It calculates %DV against current Daily Values

The percent Daily Value column is arithmetic against the current US Daily Values — which were updated, with several nutrients changing units. Panel software should hold the current reference values and compute %DV automatically, so the panel can't silently drift onto outdated figures. The math follows the rule, not a stale lookup table.

It regenerates when the formula changes

A panel is a snapshot of a formula. Change a dose, swap a source, adjust a serving size, and the panel has to change with it. Software that generates the panel from the live formula regenerates it instantly; a standalone artwork file has to be edited by hand every time, which is how labels end up describing a product that's no longer in the bottle.

It handles blends and no-DV ingredients

Botanicals, amino acids, and novel ingredients with no established Daily Value have their own presentation rules, and proprietary blends need correct descending-order, total-weight handling. A capable generator manages both — and can switch a formula between a fully disclosed panel and a blended one without re-keying everything.

This is general information, not regulatory or legal advice. US requirements change and turn on specifics, so confirm current rules with the FDA, FTC, or a qualified US regulatory expert before relying on them.

Where Lemoniq fits

Lemoniq generates the US Supplement Facts panel directly from the structured formula — correct order, units, current Daily Values, rounding, no-DV handling, and blends — and regenerates it whenever the formula changes, alongside the specs, claims, and documentation that come from the same source.

The takeaway

A genuine Supplement Facts panel generator encodes the 21 CFR 101.36 rules and builds the panel from the formula, rather than drawing a box around numbers you have to get right yourself. For a US brand maintaining many labels, that's the difference between a one-off graphic and a panel that stays correct as the product evolves.

Lemoniq turns one formula into compliant, US-ready outputs — panel, claims, specs, and documentation — from a single source. We solve this exact problem. See how it works
