The Supplement Label Test: What 'Proprietary Blend' Actually Means
Proprietary blend supplements group multiple ingredients under a single total weight, which lets brands hide individual doses on the label. For athletes tracking caffeine, stimulants, or recovery compounds, that hidden layer is the difference between a dose that works and a dose that is mostly filler. STRIPPIES publishes every ingredient and every dose on every strip.
Frequently Asked Questions
What is a proprietary blend in a supplement?
A proprietary blend is a group of two or more ingredients listed under one combined weight on a supplement label. The FDA allows this format. The brand is not required to publish the individual dose of each ingredient inside the blend.
Why do supplement brands use proprietary blends?
Brands say it protects their formula. In practice, it hides underdosed ingredients. A blend labeled 500mg can contain 495mg of one cheap ingredient and trace amounts of the ingredients the brand advertises. The label looks full. The formula is not.
How can athletes tell if a supplement label is transparent?
Read the Supplement Facts panel. Every active ingredient should have its own line with its own milligram dose. If two or more ingredients share a single weight, that is a proprietary blend. You cannot verify what you are actually taking.

World Health Day is a good day to read a supplement label. Most athletes do not. Most labels are built so you cannot.
If you train seriously, you track macros. You track sleep. You track caffeine timing before a session. Then you pick up a pre-workout tub and the label says "Energy Matrix: 1,250mg." You have no idea what is in it. Neither does the brand tell you. That is by design.
What a Proprietary Blend Supplement Actually Is
A proprietary blend is a group of ingredients listed under one total weight. Under FDA rules for dietary supplement labeling (21 CFR 101.36), brands must list the ingredients inside a blend in descending order by weight. They do not have to disclose how much of each.
The practical result: a 1,000mg blend can be 950mg of one cheap ingredient and 50mg split across five others. The five others are the ones the marketing promises.
Athletes care about this more than most buyers. You need to know your caffeine dose before a race. You need to know your beta-alanine dose to hit the threshold where it works. You need to know whether the L-theanine on the label is 100mg or 5mg, because those are two different products.
Your Questions About Label Transparency, Answered
What exactly is hidden? The individual dose of every ingredient inside a proprietary blend. You see the total. You see the order. You do not see the amount.
Is this legal? Yes. The FDA permits proprietary blends for dietary supplements. The requirement is disclosure of total weight and descending-order listing, not per-ingredient doses.
Why does it matter for performance? Ingredient dose determines whether an ingredient does anything. Research on caffeine, creatine, and beta-alanine is dose-dependent. An underdosed ingredient on a label is not a smaller version of the effect. It is no effect, with a premium price tag.
How to Read Past a Proprietary Blend
Three steps. No guru required.
One. Find the Supplement Facts panel. Ignore the front of the package.
Two. Look for any ingredient line that groups two or more items under a single milligram weight. That is a proprietary blend, even if the brand calls it a matrix, complex, formula, or system.
Three. Check whether every active ingredient has its own line with its own dose. If yes, the brand has chosen transparency. If no, the brand has chosen to hide something.
This is not a personality test for the brand. It is a test for you. If you cannot verify the dose, you cannot verify the product.
What STRIPPIES Does Differently
STRIPPIES publishes every ingredient and every dose on every strip. No blends. No matrices. No hidden weights.
On STRIPPIES ENERGY, the label says 50mg Green Coffee Bean Extract for caffeine, 1000mcg B12, 30mg L-Theanine, and 20mg Korean Ginseng. Four active ingredients. Four doses. That is the entire active profile.
On STRIPPIES SLEEP, the label says 5mg Melatonin, 50mg L-Theanine, 10mg Lavender, 10mg Chamomile, 10mg Hibiscus, and 50mg Valerian. Six actives. Six doses. You can verify every one.
Only we put more control in your hands — every ingredient listed, every dose published, minutes to feel it. That is the position. It is also just what the label says.
Why Athletes Should Care on World Health Day
Health accountability starts with what goes in your body. You already read food labels. You already track training load. The supplement stack is the last place most people still accept a black box.
A dissolvable supplement strip is not a shortcut around the question. It is a format that makes the question easier to answer, because there is less to hide. Four to six ingredients. Published doses. Put it on your tongue. Works in minutes.
Every strip. More control. Nothing wasted. Read the label. Ask the dose. If the brand will not answer, the brand is the answer.
