Use a consistent quantity for both products
FDA explains that supplement labels identify serving size and ingredient amounts, subject to rules for proprietary blends. Multiply declared creatine per serving by the number of servings to estimate the package’s total. [1]
Then divide the package price by that declared quantity. Keep grams and milligrams consistent, and do not treat the total weight of a flavored blend as pure creatine. [1]
Price arithmetic is not a quality ranking
The calculation compares label-declared supply, not independently measured content or suitability. Product identity, formulation and verification remain separate checks. [1]
When a blend does not disclose the creatine amount, an accurate cost-per-gram comparison cannot be completed from the front label. Do not fill the gap with an assumed percentage. [1]
Compare two fictional packages
Imagine package A costs $20 for 100 declared grams and B costs $30 for 200. Their costs are $0.20 and $0.15 per declared gram, respectively; this does not establish which product is appropriate.
| Detail | Interpretation |
|---|---|
| Total creatine | Per serving × servings |
| Unit cost | Price ÷ declared grams |
| Quality | Separate verification |
