Quick take
The useful answer in 30 seconds
- Protein density = protein grams ÷ serving grams × 100.
- A high density can mean less non-protein material by weight.
- Density is not a quality, taste or suitability score.
The calculation
Divide protein grams by serving grams and multiply by 100. For example, 24g of protein in a 30g serving equals 80% protein density.
| Example | Calculation | Density |
|---|---|---|
| A | 24 ÷ 30 × 100 | 80% |
| B | 24 ÷ 40 × 100 | 60% |
What the rest of the serving may contain
The non-protein portion can include carbohydrates, fats, fiber, flavors, sweeteners and texture ingredients. A lower density is not automatically a problem if those ingredients are useful for your recipe or preference.
Use density with calories, sugar, ingredients and price. It is most helpful when products provide similar protein amounts but different serving weights.
Use density as a shortlist filter
Set a density threshold only after filtering for dietary fit. Then compare cost per 25g of protein and verify the package label. Protein Compare Hub calculates density only when both required label inputs are available.
FAQ
Frequently asked questions
Is 80% density good?
It is a useful comparison signal, not a universal quality standard. The right threshold depends on what else you want in the formula.
Does density include calories?
No. Density uses protein grams and serving grams; calories are a separate label field.
Why is density blank for some products?
The required protein or serving-size label value has not been verified, so no value is estimated.
