FAQ

Should I sift Whey protein powder before a teaspoon measure?
No — the table uses unsifted values. Sifting makes the powder lighter per spoon, reading about 20 % less.
Does the brand of Whey protein powder change the gram value meaningfully?
For most household brands, no — density varies <5 %. Professional bakery variants (e.g. high-protein, strong-rise) may differ more; check the package label.
