✓

Proprietary Blend Total Weight Only21 CFR 101.36(c)

Per 21 CFR 101.36(c), a proprietary blend declares ONLY the total blend weight in the Amount column. Individual constituents are listed indented below with NO amounts shown — this protects trade secrets while maintaining transparency.

✓

Descending Order by Weight21 CFR 101.36(c)(2)

Constituents within a proprietary blend must be listed in descending order by weight (largest first). FDA Form 483 observations frequently cite brands for listing constituents alphabetically or by marketing preference rather than actual weight.

✓

Vitamin %DV Inside Blends21 CFR 101.36(c)

If a proprietary blend contains vitamins with established RDI (e.g., Vitamin B6, B12), the %DV must be declared for the vitamin portion, even though the constituent amount is concealed. The vitamin line appears outside the blend with its own amount and %DV.

FDA Label Formatting Guide for Sports Pre-Workout Powder

Pre-workout supplements are the most FDA-scrutinized supplement category due to the widespread use of proprietary blends, high-dose stimulants, and synthetic amino acids. This template demonstrates compliant dual proprietary blend formatting under 21 CFR 101.36(c), including correct descending order by weight, blank constituent amounts, and accurate %DV for added vitamins (B6, B12).

Pre-workout labels frequently trigger FDA warning letters for three reasons: (1) listing individual constituent weights inside a proprietary blend (not permitted — only the total blend weight is declared), (2) failing to list constituents in descending order by weight, and (3) omitting %DV for vitamins added to the formula. This template avoids all three violations.

Frequently Asked Questions

How to list a proprietary blend on a supplement facts label?

Per FDA 21 CFR 101.36(c), list "Proprietary Blend" with the total weight, then indented constituents in descending order by weight. Individual constituent amounts are NOT shown — only the total blend weight appears in the amount column.

Does caffeine need to be listed separately on a pre-workout label?

Caffeine can be part of a proprietary blend OR listed separately as a dietary ingredient. When listed separately, show the total caffeine amount (e.g. 250 mg). The %DV column shows "†" as caffeine has no established Daily Value.

How are blend constituents ordered on an FDA label?

Per FDA 21 CFR 101.36(c)(2), constituents within a proprietary blend must be listed in descending order by weight. The blend root shows the total weight; individual constituents are indented without amounts.
