The Supplement Buyer’s Cheat Sheet cover

What’s inside

Most premium supplement brands don't make anything. They buy from the same contract manufacturers as everyone else, then price in the ads, the influencers and the shelf space.

This three-page cheat sheet gives you the five questions to ask before you buy, a real cost comparison, and an honest list of what is worth it, what is situational and what is usually marketing.

  1. Where the markup comes fromWhat you are really paying for
  2. Check 1: full label transparencyWhy proprietary blends hide small doses
  3. Check 2: third-party testingAnd why a GMP facility is not the same thing
  4. Check 3: clinically relevant dosingDo the amounts match the studies?
  5. Checks 4 and 5: supply chain and priceWho makes it, and the cost per serving
  6. The real cost comparisonA retail brand next to a product that passes the check
  7. Worth it for most peopleProtein, a basic multi, omega-3 and creatine
  8. Situational, and usually marketingGreens, collagen, vitamin D, and what to skip
  9. Start with your biggest gapOne pick for protein, one for inconsistent meals
