Did my protein powder shrink its scoop?

THE SHORT ANSWER

None of the 192 protein powders FormulaSignal has verified to the label has a confirmed serving-size change on file. 2 other verified products do: RSP Nutrition AminoLean Energy / Pre Workout, from 8.2 g to 7.80 g per serving and Cellucor C4 Sport Pre-Workout, from 12.6 g to 12.2 g per serving. Archives have not yet been fully searched for 192 of the 192 protein powders, so this is not proof none changed.

The scoop in your tub is not the label: compare the grams per serving and servings per container printed on the panel.

The evidence

Check yours

Check your scoop in three steps.

  1. Read grams per serving, not scoops.The panel prints the serving in grams. A scoop is a tool; the grams are the claim.

  2. Multiply by servings per container.Grams per serving times servings should come close to the net weight on the front.

  3. Compare with a dated label.Use the table above, or a photo of your last tub's panel.

Method

How this page was made.

What FormulaSignal did

  • Answered from the 515 records that are Signal Verified today: labels read twice, dated and sourced.
  • Counted a change only between two dated labels of the same product, flavor, size and sales channel.
  • Computed every figure on this page from those records when the page was served, so it moves when the Record does.

What it did not do

  • No look inside a tub. A label says what a product declares. A record does not establish what a particular container holds.
  • No taste test and no lab test. Every figure is what a label or a brand's own page declares, not what was measured in a tub.
  • No score and no winner. Differences are measured and shown; nothing is rated.
  • No payment and no preview. No brand paid to appear, and none saw this page before it was published.
  • No health advice. Whether an ingredient or an amount suits you is a question for a clinician.

Questions

More questions

Is a smaller scoop a formula change?

A smaller printed serving is a label change. Whether the protein per serving moved is a separate line on the panel; compare both.

Why is my scoop smaller but the label the same?

Scoops can be swapped without the label changing. The label's grams per serving is what the brand declares; weigh a scoop if it matters to you.
