# The Supplement Label Test: What "Proprietary Blend" Actually Means Published 2026-04-11 · Max Ninthara · Tags: athlete supplements, dissolvable supplement strips, ENERGY, ingredient transparency, label reading, proprietary blend, SLEEP, STRIPPIES, supplement guide, supplement transparency "Proprietary blend" appears on thousands of supplement labels. It sounds protective. What it actually hides is the dose. This article explains what proprietary blends mean, how to spot under-dosing from the label alone, and what genuine ingredient transparency looks like — so athletes can evaluate what they're actually taking. Frequently Asked Questions What does "proprietary blend" mean on a supplement label? A proprietary blend groups multiple ingredients under one combined weight. The total blend weight is disclosed. Individual doses are not. It is legal under current FDA rules. You see the ingredients — you do not see how much of each one is inside. How can I tell if a supplement is under-dosed from the label? Divide the total blend weight by the number of ingredients for an average per-ingredient dose. Compare that average to studied dose ranges for each key ingredient. If the math doesn't support a meaningful amount, the label is doing marketing work, not informational work. What should a transparent supplement label show? Every ingredient by name. Every individual dose in milligrams. No grouped blends, no matrices, no complexes that hide quantities. A transparent label gives you enough information to evaluate the product on dose — before you take it. *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. The words "proprietary blend" appear on thousands of supplement labels. They sound protective. Like the brand is guarding something valuable. What they're actually guarding is the dose. You don't know how much of anything is in there. That is the point. Here is how to read a supplement label — and what it looks like when a brand decides to stop hiding. What "Proprietary Blend" Actually Means A proprietary blend is a group of ingredients listed under one collective weight. The total amount is disclosed. Individual doses are not. You might see "Energy Complex 600mg" followed by five ingredients. The blend weighs 600mg total. Ingredient A could be 590mg. Ingredients B through E could be 2.5mg each. You cannot tell from the label. The FDA does not require brands to disclose individual doses within a blend. Some use this to protect formulations from competitors. Others use it to under-dose expensive ingredients while keeping them on the label for marketing value. Both are legal. Neither is transparent. Three Things a Supplement Label Must Tell You Here is the minimum required by law: Every ingredient by name The total weight of any blend All other ingredients: fillers, binders, coatings What labels don't have to show: individual doses within a blend. That is where the hiding happens. If you want to know what 400mg of a blend actually delivers per ingredient — you can't find out from the label. You would need a lab. How to Spot Under-Dosing Without a Lab The label gives you limited information. Use it. Count the ingredients in a blend. Divide total blend weight by that number for an average per-ingredient dose. Then look up studied dose ranges for each key ingredient. Research on caffeine and L-theanine suggests both are studied at specific dose thresholds — information widely available via NIH and PubMed. B12 bioavailability varies considerably by form and dose. If the math on a blend can't support meaningful amounts of its key ingredients, the label is not giving you enough to evaluate the product. Also check ingredient order within the blend. Ingredients are listed highest to lowest within each grouping. If the ingredient you care most about is last on a low-weight blend, the math does the rest of the work for you. What Transparent Ingredient Labeling Looks Like Every ingredient. Every dose. Listed individually. No blends, no matrices, no proprietary anything. It is not common. Most supplement brands — across pills, powders, gummies, and strips — use some form of blend labeling. The brands that don't have made a deliberate choice: they would rather you know exactly what you're taking than protect a formula you can't verify. That choice invites direct comparison. It means you can evaluate a product on dose, not just on ingredient names. Athlete Questions About Supplement Labels Why do brands use proprietary blends? Mostly to prevent competitors from copying formulas. Sometimes to keep costs low by under-dosing expensive ingredients. Sometimes both. The reason doesn't change what's on — or missing from — the label. Is a higher total blend weight better? Not necessarily. A 1000mg blend with ten ingredients might deliver less of a key ingredient than a product that lists that ingredient individually at 200mg. Total weight is not a proxy for effective dosing. What if the label shows no blend — just individual ingredients? That is the best case. Individual listing means individual disclosure. You can verify the dose, compare it to studied ranges, and decide with actual information. STRIPPIES: Every Ingredient. Every Dose.
