Methodology

How Scoop Sage makes products comparable.

Scoop Sage structures product facts, normalizes them into common units, and calculates metrics that answer practical shopping questions.

1. Keep product variants distinct

Flavor, package size, serving count, formulation, and seller can all change the comparison. We aim to keep materially different variants separate instead of blending them into a misleading average.

2. Structure and review source facts

Product identity, package facts, nutrition-label values, retailer offers, and observation times are stored as separate facts. Automated extraction can help organize the catalog, but uncertain or conflicting values may be withheld until they can be reviewed.

A dash in a comparison means we do not have a usable value. It does not mean zero.

3. Normalize protein-powder comparisons

Per-serving nutrition can be distorted by different package and serving sizes. Scoop Sage converts the comparison values to the same protein amount: 25 grams.

Calories per 25 grams of protein

(calories per serving ÷ protein grams per serving) × 25

Other nutrients per 25 grams of protein

(nutrient amount per serving ÷ protein grams per serving) × 25

The same calculation is used for carbohydrates, fat, sodium, cholesterol, fiber, sugars, calcium, iron, potassium, and other published nutrition values.

Calculated values inherit the limitations of their inputs. When a required value is missing, we leave the metric blank rather than estimate it.

4. Let the shopper choose what matters

Filters and sortable columns expose the underlying facts instead of declaring one universal “best” product. Default ordering follows the category's documented comparison logic and is never purchased by a manufacturer or merchant.

Known limitations

  • Manufacturers can change formulas, labels, and packages without notice.
  • Automated extraction and manual review can still contain errors.
  • Seller listings may combine variants or contain incorrect details.
