What the confirmed change shows
On Momentous's own Unflavored Whey Protein Supplement Facts panel, the scoop moved from 23.6 g to 23.7 g and the grass-fed whey protein isolate line from 23.3 g to 23.4 g. Calcium fell from 100 mg to 90 mg, sodium rose from 45 mg to 55 mg, total carbohydrate moved from less than 1 g to 1 g, and a potassium line of 100 mg appeared. The vitamin D (0.4 mcg) and cholesterol (less than 5 mg) lines no longer appear. Calories 90, protein 20 g, total sugars less than 1 g, ProHydrolase 200 mg and 25 servings did not move.
Both endpoints are first-party Unflavored panel images from Momentous's own storefront, preserved on their observation dates and each read twice independently with every field agreeing. The product page preserved on 2026-09-26 embeds the earlier panel file (TM3_SupplementFacts_Whey); on 2026-10-26 the page no longer serves that file and describes the new image as the Unflavored Supplement Facts, 25 servings, 1 scoop 23.7g. The window is two observation dates, not a launch or manufacture date, and older tubs may remain on shelves. No laboratory testing is claimed.
Tastes different?
Check your tub against this label. Line by line.
Turn your tub to the Supplement Facts panel. If an amount differs, you hold a different label from the one read here. If every line matches, the label does not explain the difference.

Not checked yet
- 3 of 4 flavors on the brand's store (2026-10-26) have no panel read yet.
- Retail labels have not been compared with the brand's own store.
- Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
Labels read from the brand's own store (DTC) channel only. Other channels may sell a different label. The panel is declared product-wide; flavor-specific panels read: UNFLAVORED. US market only.

Method
How this page was made.
What FormulaSignal did
- Read the label Momentous published for Unflavored, dated Oct 26, 2026, twice and independently: 33 of 33 fields agreed.
- Kept all 2 dated labels with the day each was seen and its source.
- Counted a change only between two dated labels of the same flavor, size and sales channel: 1 confirmed change on file.
- Printed every gap the Record knows about, above, instead of leaving it out.
What it did not do
- No look inside your tub. A product record does not establish what a particular container holds, and label dates are not manufacture dates.
- 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
Momentous Whey Protein Isolate: formula questions
Did Momentous Whey Protein Isolate change its formula?
Yes. Calcium went from 100 mg to 90 mg. Grass Fed Whey Protein Isolate went from 23.3 g to 23.4 g. Between labels seen Sep 26, 2026 and Oct 26, 2026, compared like for like.
My Momentous Whey Protein Isolate tastes or feels different. Is it a new formula or a bad batch?
A label can answer half of that: whether the formula on the label changed. Compare the Supplement Facts panel on your tub with the label dated Oct 26, 2026 on this page (it declares Calcium 90 mg, Potassium 100 mg and Grass Fed Whey Protein Isolate 23.4 g per serving). If your amounts differ, you hold a different label from the one on file. If they match, the label does not explain the difference. FormulaSignal does not test what is inside a tub.
How do I know if I have the old or new Momentous Whey Protein Isolate?
Read the Supplement Facts panel. The label seen Sep 26, 2026 declares 100 mg calcium; the label seen Oct 26, 2026 declares 90 mg. The label seen Sep 26, 2026 declares 23.3 g grass fed whey protein isolate; the label seen Oct 26, 2026 declares 23.4 g. The date on a tub is not a formula date, so go by the amounts printed.
What did FormulaSignal check, and what not yet?
Checked: the Unflavored label from Momentous, dated Oct 26, 2026, read twice with 33 of 33 fields matching. Not yet: 3 of 4 flavors on the brand's store (2026-10-26) have no panel read yet; Retail labels have not been compared with the brand's own store; Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
