About MacroSaver & Our Methodology

Catalog and price data

Products are selected and entered manually; the catalog is not a complete survey of the market. Prices are manually maintained snapshots of the offers shown and can change at any time. The current dataset does not include observation timestamps, so MacroSaver does not claim that a displayed price is current. Many products also have only one tracked retailer; a recorded price is not the lowest price available anywhere.

Always verify the retailer price, package size, serving count, ingredients, and availability before purchasing. Out-of-stock offers are excluded from value rankings when that status is known.

How value metrics are calculated

Cost per serving

Recorded available offer price ÷ servings in the package

Protein per dollar

Protein grams per serving ÷ cost per serving

Cost per ounce of protein

Recorded offer price ÷ total protein ounces in the package

Calculations use the serving and nutrition values in our catalog. Manufacturers can change labels and formulations, and data-entry errors are possible. A low calculated cost is a value signal, not a judgment about quality, safety, or suitability.

Named community endorsement badges identify a contributor's product list. They are not a clinical certification, safety determination, or substitute for individualized advice.

Affiliate and ranking policy

MacroSaver may earn a commission when you buy through a marked retailer link, at no added cost to you. Affiliate status does not alter the formulas. Product lists are ordered using the selected on-page metric and filters, not commission rate. We do not accept payment for user reviews.

Nutrition and health content

Guides and recipes are general educational content, not medical advice, diagnosis, or individualized nutrition care. MacroSaver does not currently claim that this content has been reviewed by a physician or registered dietitian. People who are pregnant, take medication, have a medical condition, or have had bariatric surgery should confirm choices with their qualified care team and follow the product label.

General reference sources include the NIH Office of Dietary Supplements, FDA caffeine guidance, and NIDDK bariatric surgery information.
