A proprietary blend is a mixture of ingredients listed under a single total weight, without disclosing the individual amount of each ingredient. The FDA requires companies to list ingredients in descending order by weight within the blend — but not the individual amounts.

Example: "Energy Matrix 500mg: Caffeine, L-Theanine, Green Tea Extract, Guarana, Taurine." You know the total blend is 500mg and that caffeine is the heaviest ingredient. You don't know if it's 400mg caffeine and 25mg of everything else, or 100mg of each.

Companies claim proprietary blends protect their "unique formulas" from competitors. In reality, most supplement formulas are not trade secrets — the same ingredients appear across hundreds of products. The real purpose of proprietary blends is to hide the fact that expensive ingredients are underdosed while cheap ones are overdosed.

The math is simple: if a proprietary blend weighs 500mg and contains 8 ingredients, the average ingredient gets 62.5mg. If the first ingredient (cheapest, often caffeine or maltodextrin) accounts for 300mg, the remaining 7 split 200mg — averaging 28mg each. Most effective ingredient doses are 200-600mg. A 28mg dose of almost anything is fairy dust.

Serving size is one of the most powerful tools for making a product look better than it is.

Trick 1: "Per Serving" Math. A pre-workout says "6g Citrulline" on the front. Flip it over: "Serving size: 2 scoops." One scoop = 3g. Most people use one scoop. They're getting half the advertised dose.

Trick 2: Unrealistic Serving Sizes. A bag of chips says "150 calories." Serving size: 8 chips. Nobody eats 8 chips. The realistic serving (30+ chips) is 500+ calories. This applies to supplements too — a "30-day supply" multivitamin might require 4 capsules per serving. Take 2 (because who wants to swallow 4 pills?) and you get half the labeled nutrients.

Trick 3: Capsule Count vs Serving Count. A bottle says "60 capsules" and "500mg Magnesium." Sounds like 60 days of magnesium. But if the serving size is 2 capsules, that's a 30-day supply and 250mg per capsule. Bottles are priced by capsule count, but value is determined by servings.

Trick 4: Front-of-Label vs Supplement Facts Discrepancy. The front might say "1000mg Omega-3 Fish Oil" but the Supplement Facts shows 300mg EPA + 200mg DHA = 500mg actual omega-3. The other 500mg is other fish fats. The front number is technically the fish oil weight, not the active fatty acid content.

The defense: ALWAYS read the Supplement Facts panel. Ignore the front of the label. Calculate cost per effective serving, not cost per bottle.

You learned in Tier 1 that sugar hides under 60+ names. The Tier 2 skill is understanding WHY companies split sugar into multiple types and how to calculate total sugar impact.

Ingredients are listed by weight in descending order. If a product's primary ingredient is sugar, it looks bad. So companies use 3-4 different sugars — each appears lower on the ingredient list individually, but combined they're the dominant ingredient.

Example: A granola bar lists "Oats, Brown Rice Syrup, Cane Sugar, Honey, Corn Syrup..." Oats are first, which looks healthy. But if you combined the three sugars (brown rice syrup + cane sugar + honey + corn syrup), sugar would be the #1 ingredient by weight.

Advanced Detection: Look at the Nutrition Facts panel. If a product has 12g total sugar per serving but only 1-2g from the primary ingredient (like oats), then 10-11g came from added sugars. Cross-reference the ingredient list to identify which sugars contribute.

"Added Sugars" Labeling: Since 2020, the FDA requires "Added Sugars" to be listed separately on the Nutrition Facts. This makes the splitting strategy less effective for informed consumers — but many people still don't check this line.

The price on the bottle is designed to obscure the actual cost of what you're getting. Here's how to calculate real value:

Step 1: Find the serving size in the Supplement Facts panel (not the front of the label).

Step 2: Count total servings per container (listed at the top of Supplement Facts).

Step 3: Divide bottle price by total servings = cost per serving.

Step 4: Check the dose per serving against the research-backed dose. If the product provides half the effective dose, double your cost-per-serving (because you'd need two servings to reach the studied dose).

Example: Brand A magnesium glycinate costs $25 for 120 capsules. Serving size: 2 capsules = 400mg. That's 60 servings at $0.42/serving with a full effective dose.

Brand B magnesium glycinate costs $15 for 60 capsules. Serving size: 1 capsule = 100mg. That's 60 servings at $0.25/serving — but you'd need 4 capsules to match Brand A's dose, making the real cost $1.00/effective serving. Brand B is actually 2.4x more expensive for the same result.

This math exposes why cheap supplements are often the most expensive per effective dose.
