What the confirmed change shows
On Momentous's own Fuel Passion Orange Guava Nutrition Facts panel, sodium went from 280 mg to 300 mg and potassium from 140 mg to 150 mg per scoop. Calories 120, total carbohydrate 28 g, total sugars 27 g (all added), magnesium 100 mg, zinc 3 mg, a 33.1 g scoop and 15 servings did not move.
The earlier endpoint is the brand's own 15-serving Passion Orange Guava jar panel image (Fuel15-POG-Jar-Supps) served by the Wayback Machine on 2025-10-16 and still in the gallery of the archived Fuel product page of 2026-02-07. The newer endpoint is the Passion Orange Guava panel preserved from the current product page on 2026-09-26. Each was read twice independently with every field agreeing. The window is two observation dates, not a launch or manufacture date, and tubs with the earlier label 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 (2026-09-26) 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: Passion Orange Guava. US market only.

Method
How this page was made.
What FormulaSignal did
- Read the label Momentous published for Passion Orange Guava, dated Sep 26, 2026, twice and independently: 57 of 57 fields agreed.
- Kept that label 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 Fuel: formula questions
Did Momentous Fuel change its formula?
Yes. Potassium went from 140 mg to 150 mg. Between labels seen Oct 16, 2025 and Sep 26, 2026, compared like for like.
My Momentous Fuel 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 Sep 26, 2026 on this page (it declares Vitamin D 0 mcg, Calcium 0 mg and Iron 0 mg 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 Fuel?
Read the Supplement Facts panel. The label seen Oct 16, 2025 declares 140 mg potassium; the label seen Sep 26, 2026 declares 150 mg. 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 Passion Orange Guava label from Momentous, dated Sep 26, 2026, read twice with 57 of 57 fields matching. Not yet: 3 of 4 flavors on the brand's store (2026-09-26) 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.
Will I find out if Momentous Fuel changes its formula later?
