What the confirmed change shows
On NutraBio's own Base Pre-Workout Blue Raspberry Supplement Facts panel, vitamin B12 (as methylcobalamin) 150 mcg, printed at 6,250% DV in 2025, is no longer listed. Every other dosed line did not move: L-citrulline 6 g, beta-alanine 3.2 g, betaine anhydrous 2.5 g, L-tyrosine 1.5 g, taurine 1 g, caffeine anhydrous 200 mg, Himalayan pink salt 100 mg, Astragin 50 mg, chloride 59 mg, sodium 40 mg, a 16.7 g scoop and 30 servings.
The 2025 endpoint is the brand's own panel image (21981-sfp, Blue Raspberry) served by the Wayback Machine on 2025-03-28 and referenced by the archived Base product page of 2024-12-05. The 2026 endpoint is the panel preserved from the current product page on 2026-08-03, also Blue Raspberry. 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.

- 3 of 4 flavors on the brand's store (2026-10-04) 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: Blue Raspberry. US market only.

Method
How this page was made.
What FormulaSignal did
- Read the label NutraBio published for Blue Raspberry, dated Aug 3, 2026, twice and independently: 32 of 32 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
NutraBio Base Pre-Workout: formula questions
Did NutraBio Base Pre-Workout change its formula?
Yes. A confirmed label change is on file. On NutraBio's own Base Pre-Workout Blue Raspberry Supplement Facts panel, vitamin B12 (as methylcobalamin) 150 mcg, printed at 6,250% DV in 2025, is no longer listed. Every other dosed line did not move: L-citrulline 6 g, beta-alanine 3.2 g, betaine anhydrous 2.5 g, L-tyrosine 1.5 g, taurine 1 g, caffeine anhydrous 200 mg, Himalayan pink salt 100 mg, Astragin 50 mg, chloride 59 mg, sodium 40 mg, a 16.7 g scoop and 30 servings. Between labels seen Mar 28, 2025 and Aug 3, 2026.
My NutraBio Base Pre-Workout 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 Aug 3, 2026 on this page (it declares Chloride 59 mg, L-Citrulline 6 g and Beta Alanine 3.2 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.
What did FormulaSignal check, and what not yet?
Checked: the Blue Raspberry label from NutraBio, dated Aug 3, 2026, read twice with 32 of 32 fields matching. Not yet: 3 of 4 flavors on the brand's store (2026-10-04) 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 NutraBio Base Pre-Workout changes its formula later?
