Proprietary Blends Are Where Underdosing Hides

Pick up a supplement from the shelf at any big-box retailer. Turn it over. Read the label. Somewhere in the "Supplement Facts" panel you will probably find a line that looks like this:

Proprietary Performance Matrix — 2,450 mg

• L-Citrulline
• Beta-Alanine
• Betaine Anhydrous
• Agmatine Sulfate
• Taurine
• Creatine Nitrate

Six ingredients. One number. No breakdown.

That is a proprietary blend, and it is the single most reliable signal in the supplement industry that you are about to be underdosed.

The loophole, in one sentence

The FDA requires a supplement label to disclose the total weight of a "proprietary blend" and to list the ingredients in descending order by weight — but it does not require the manufacturer to tell you how much of each individual ingredient is in that blend. As long as the total weight is accurate and the order is correct, the manufacturer can put 2,400 mg of the cheapest ingredient and 10 mg of each of the other five, and the label is perfectly legal.

In a competitive, low-margin industry, that is exactly what tends to happen.

Why this matters: the clinical doses are not close

The effective doses for the most-studied performance ingredients are not small, and they are not flexible. Here are the numbers the peer-reviewed literature converges on:

• L-Citrulline: 6,000–8,000 mg, 60 minutes pre-workout, for blood-flow and performance effects.
• Beta-Alanine: 3,200–6,400 mg per day (typically split to manage paresthesia) for meaningful muscle carnosine elevation.
• Betaine Anhydrous: 2,500 mg per day.
• Creatine Monohydrate: 5,000 mg per day (not "creatine nitrate," "creatine HCl," or "creatine MagnaPower" — monohydrate is what the studies used).
• Taurine: 1,000–2,000 mg per dose for the most commonly cited effects.

Add those up. The effective daily doses of just the first four ingredients — citrulline, beta-alanine, betaine, creatine — total around 16,700 mg per dose. Almost 17 grams.

Now look back at that proprietary blend: 2,450 mg, six ingredients. Even if the blend were split evenly (it never is), that is ~408 mg per ingredient. That is roughly 6% of the clinical dose of citrulline, 12% of beta-alanine, 16% of betaine, 8% of creatine.

The label is not lying. The product is simply not dosed to do what the ingredients suggest it does.

The "pixie-dusting" tactic

The industry term for this is "pixie dusting." You sprinkle just enough of a big-name research-backed ingredient into a formula to put it on the label and trigger the consumer's pattern-matching ("oh, that has citrulline in it, I've heard of that") — but not enough to produce the effect the research describes.

Pixie dusting is possible because of two legal facts:

1. The FDA does not require per-ingredient dosage disclosure inside a proprietary blend.
2. "Structure-function" claims on the label ("supports muscle recovery," "promotes endurance") are not held to the same evidence standard as drug claims. The brand does not have to prove the product delivers the claimed effect — only that the ingredient in general has been associated with that effect in some study, somewhere.

The combination means a product can contain a homeopathic dose of a well-studied ingredient and still legally market itself using the science that was done on the full clinical dose.

"But it's a synergy blend"

The most common defense of proprietary blends is that the ratios are proprietary trade secrets — that the brand has discovered a special synergy and is protecting the recipe.

This is almost always false. Here's why:

• Synergy claims require evidence. If a specific ratio produces an effect that the individual ingredients do not, there should be a study on that specific formulation showing it. In the decades proprietary blends have existed, the number of blend-specific peer-reviewed efficacy studies you can count on one hand.
• Reverse-engineering is trivial. Any competitor with a mass spectrometer and a week can determine exactly what's in a blend and at what ratios. The "trade secret" hides the formula from the consumer, not from competitors.
• The ingredients in question are decades old. Citrulline, beta-alanine, betaine, creatine — none of these are novel. The research on each is extensive and independent. There is no "secret combination" of public-domain compounds waiting to be discovered by a marketing team.

The proprietary blend hides the dosing from you. That is the only thing it reliably does.

What a label should look like instead

A label written for the person taking the product, not the person selling it, shows every ingredient with its exact dose. No blend, no matrix, no matrix-blend-complex. Every milligram accounted for.

Example of a transparent label:

• L-Citrulline — 8,000 mg
• Beta-Alanine — 3,200 mg
• Betaine Anhydrous — 2,500 mg
• Creatine Monohydrate — 5,000 mg
• Taurine — 1,000 mg

That is a label you can check against the literature. You can ask "is this dose consistent with the studies?" and get an answer in five minutes on PubMed. You cannot do that with a proprietary blend, which is the point.

At Scythene, every product we make discloses every ingredient at every dose. No blends. No matrices. No synergy complexes. The math either works or it doesn't, and you get to check it yourself.

How to audit a supplement in 90 seconds

Next time you're evaluating a product — ours or anyone else's — run this checklist:

1. Look for the word "blend," "matrix," "complex," or "formula" followed by a single total-milligram number. If it's there, the label is hiding doses.
2. Pick the ingredient the product is marketed on (whatever the front of the bottle is shouting about — citrulline, creatine, beta-alanine, whatever).
3. Check the per-serving dose against the clinical literature. If the label says "Pump Matrix 2,500 mg" and citrulline is the first ingredient, the theoretical ceiling on citrulline is 2,500 mg — which is already well below the 6,000–8,000 mg clinical dose.
4. Count the ingredients in the blend. More ingredients means less of each. A six-ingredient "performance matrix" at 2,500 mg is structurally incapable of delivering clinical doses of any of them.
5. If all of those are red flags, put the product down and find one with transparent dosing.

Labels are a contract. A company that won't tell you how much of each ingredient is in the bottle is writing a contract that only one side can read — and that side is not yours.

That is the industry we are trying to move away from, one transparent label at a time.
