Not checked yet
- 7 of 8 flavors on the brand's store (2026-10-31) 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: Dutch Chocolate. US market only.
Label read twice. Both readings agree. Not a laboratory test, safety certification, or endorsement of the product. How Signal Verified works
Method
How this page was made.
What FormulaSignal did
- Read the label Isopure published for Dutch Chocolate, dated Oct 25, 2026, twice and independently: 102 of 102 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: 0 confirmed changes 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
Isopure Flavored Protein: formula questions
Did Isopure Flavored Protein change its formula?
No confirmed formula change is on file. The label Isopure published, dated Oct 25, 2026, was read twice and 102 of 102 fields agreed. Archives have not yet been searched for earlier labels, so this is not proof the formula never changed.
My Isopure Flavored Protein 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 25, 2026 on this page (it declares Calcium 370 mg, Iron 0.9 mg and Potassium 130 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.
What did FormulaSignal check, and what not yet?
