Quick verdict
The best labels in this group are not automatically the best products. Nerve Fresh prints all five botanical doses and uses no proprietary blend. iGenics prints all 12 active amounts, but its vitamin E and zinc wording creates internal consistency questions. Synaptigen is short and fully printed, but it does not split probiotic CFU by strain. Claritox Pro and Vertigenics share the same six printed doses and the same hidden 112 mg blend. Quietum Plus has the longest panel and the largest hidden blend: 12 botanicals in 802 mg, plus a page claim of "18 plant extracts" that does not match the label.

Why label transparency matters
A supplement label is the only part of the offer a buyer can check before paying. Marketing copy can describe a "clinically studied formula" without naming a dose. A testimonial can describe a result without proving causation. The Supplement Facts panel is different: it is a structured declaration of serving size, active amounts and other ingredients.
That does not make the panel trustworthy by itself. A label can be accurate and still describe a weak formula. It can print a dose that is far below the amount used in research. It can use a proprietary blend to hide how much of each botanical is present. It can list a species without the strain that was actually studied. And it can be internally inconsistent, as iGenics is with its vitamin E and zinc entries.
But transparency is still the right starting point. If a seller will not tell you what is in the bottle, you cannot compare the product with the evidence, estimate interaction risk, or judge whether the price is reasonable. A clear label is not proof of quality. A vague label is a reason to slow down.
How we audited the labels
We used a fixed five-part rubric for every product. We did not assign a single star rating, because a numeric score would imply a precision the documents do not support. Instead, we recorded what each label discloses and where the gaps are.
| Audit category | What we checked | Why it matters |
|---|---|---|
| Printed active doses | Whether every active ingredient has a milligram, microgram, CFU or IU amount | Without an amount, the formula cannot be compared with research doses |
| Proprietary blends | The total blend weight, the number of ingredients and whether individual amounts are hidden | A blend total does not tell you how much of each ingredient you receive |
| Identity detail | Species, strain, extract ratio, standardization marker or "as" form | Probiotic and botanical effects are often strain- and extract-specific |
| Label-to-marketing consistency | Whether the page's ingredient count, doses and mechanism match the panel | A mismatch is a documentation failure even when the product is real |
| Refund documentation | Window, return condition, who pays shipping and whether official pages agree | The refund is part of the offer and should be as checkable as the label |
We treated "label checked" as a statement about the document, not an endorsement. Where a seller made a claim we could not verify, we marked it as a seller claim. Where a product had no published trial, we said so. We did not infer that an ingredient study proves the finished product works.
The six labels at a glance
| Product | Actives with printed doses | Hidden actives | Identity detail | Label/marketing consistency | Refund documentation |
|---|---|---|---|---|---|
| Synaptigen | 3 of 3 entries | None, but CFU is not split by strain | Species named; one strain code (BL-04) | Weak Reference page cites unrelated ingredients | Clear 180 days; all bottles; buyer pays shipping |
| Nerve Fresh | 5 of 5 botanicals | None | Plant part and extract ratio for corydalis | Mixed "No side effects" is too absolute | Mixed 180 days official; some pages say 60 |
| iGenics | 12 of 12 ingredients | None | Forms named; one zinc/copper wording error | Weak AREDS2 comparison overreaches | Conflicting 60, 180 and 365-day terms |
| Claritox Pro | 6 of 10 entries | 4 botanicals in 112 mg blend | Blend names plants; no extract ratios | Mixed Ototoxin story unsupported | Mixed 60 days; page advises 3 months |
| Vertigenics | 6 of 10 entries | 4 botanicals in 112 mg blend | Blend names plants; no extract ratios | Weak Dioxin-detox story unsupported | Mixed 60 days; page advises 3 months |
| Quietum Plus | 10 of 22 entries | 12 botanicals in 802 mg blend | Species and plant parts named; no individual doses | Weak "18 extracts" vs 12-item blend | Mixed 60 days; label says 8 weeks |
Counts above treat each named active as one entry. Excipients are excluded. "Hidden actives" means ingredients inside a proprietary blend whose individual amounts are not printed.
Synaptigen: short label, hidden CFU split
Synaptigen has the shortest panel in the group. Each one-tablet serving lists inulin 100 mg, a 20 mg probiotic blend at 3.5 billion CFU at manufacture, and Streptococcus salivarius 20 mg. The other ingredients are tricalcium phosphate, microcrystalline cellulose, natural strawberry flavour and peppermint essential oil. One bottle contains 30 tablets.
On disclosure, that is better than most of the group: every active has a number. The gaps are in identity and consistency. The probiotic blend names Lactobacillus paracasei, Lactobacillus reuteri and Bifidobacterium lactis BL-04, but only one strain code is given and the CFU are not divided among the three. The label says "at the time of manufacture", not at expiry. And the official reference page cites papers on L-arginine, liver fat, pancreatic disease, guarana, gymnema, carnitine and capsaicin, none of which are in the bottle. It also links labels for two unrelated products.
That reference mismatch is the most serious documentation problem in this audit. It does not prove the tablet is unsafe. It does mean the seller's own evidence page cannot support the memory claim. For the dose-by-dose detail, see our Synaptigen ingredients guide.
Nerve Fresh: the clearest botanical panel
Nerve Fresh lists five botanicals with individual amounts per two-capsule serving: passionflower 350 mg, marshmallow root 220 mg, corydalis 10:1 extract 200 mg, prickly pear 100 mg and California poppy 90 mg, for 960 mg total. There is no proprietary blend. The label names plant parts for several ingredients and gives an extract ratio for corydalis.
This is the cleanest disclosure in the group. A buyer can compare each dose with the published research and see that the formula is entirely botanical. The label still has limits: the California poppy entry does not give an extract ratio, and the formula contains no alpha-lipoic acid, B vitamins or other nutrients commonly studied for nerve health.
The consistency problem is in the marketing, not the panel. The page says there are "no side effects", but three of the five herbs can be sedating. The refund terms also vary by page: the official terms advertise 180 days, while some third-party pages say 60. See the Nerve Fresh review for the interaction detail.
iGenics: full disclosure, inconsistent wording
iGenics prints all 12 active amounts: vitamin A 900 mcg, vitamin C 500 mg, vitamin E 0.268 mg, zinc 20 mg, copper 2 mg, bilberry 480 mg, turmeric 350 mg, ginkgo 80 mg, black pepper 20 mg, lutein 20 mg, saffron 20 mg and zeaxanthin 10 mg. There is no proprietary blend. On raw disclosure, that is a strong panel.
The problems are internal consistency. The vitamin E entry says 0.268 mg with a Daily Value of 2%. AREDS2 used 400 IU. Using the standard conversion, 0.268 mg is roughly 0.4 IU, not 400 IU. If the intended amount was 268 mg, the decimal point and the Daily Value percentage are wrong. The label also says "Zinc (as copper bisglycinate chelate)" and then lists copper separately with the same description, which looks like a transcription error.
These errors matter because the product's main selling point is an AREDS2 comparison. A label that cannot state its vitamin E dose consistently cannot support a precise "same as AREDS2" claim. The iGenics review covers the formula and the conflicting refund terms in more detail.
Claritox Pro and Vertigenics: one panel, two stories
Claritox Pro and Vertigenics have the same active panel. Each two-capsule serving lists zinc 11 mg, chromium 100 mcg, alpha-lipoic acid 150 mg, green tea leaf extract 150 mg, berberine HCl 100 mg, resveratrol 40 mg, and a 112 mg proprietary blend of milk thistle, cayenne, Korean or Asian ginseng and banaba. Both bottles contain 60 capsules.
The disclosure is identical, so the audit result is identical: six printed doses and four hidden botanicals. The blend names the plants but does not give extract ratios or individual amounts. That makes it impossible to compare the botanical portion with research. The ALA dose is 150 mg, well below the 600 mg used in much of the diabetic neuropathy research, and that research is not a vertigo treatment.
The difference is the sales story. Claritox Pro describes an "ototoxin" theory; Vertigenics describes a "dioxin detox" theory. Neither is supported by the sources we checked. Same panel, different narrative, no product-specific trial found. Read the direct Claritox Pro vs Vertigenics comparison, or the full Claritox Pro review and Vertigenics review side by side.
Quietum Plus: the largest hidden blend
Quietum Plus has the longest panel: seven vitamins and minerals, L-arginine 100 mg, L-tyrosine 100 mg, BioPerine 500 mcg and an 802 mg proprietary blend of 12 botanicals. The vitamins, minerals and three other actives have amounts. The 12 botanicals do not. That is 12 hidden doses inside the largest blend in this audit.
The page also says the formula contains "18 special high-quality plant extracts". The label lists 12 botanicals in the blend plus BioPerine, a black-pepper extract. Even if BioPerine is counted, that is 13 plant extracts, not 18. The discrepancy could be a copy error, but it is still a label-to-marketing mismatch on the product's headline ingredient count. Our 18 vs 12 count guide lists all 22 named entries.
The vitamin base is more detailed than most competitors, and the zinc 26 mg and vitamin B12 54 mcg are real doses. But the 802 mg blend prevents a dose-by-dose comparison, and the refund window is 60 days while the label says to use the product for at least eight weeks. See the Quietum Plus review for the full table.
What the proprietary blends hide
| Product | Blend total | Named ingredients | What is missing |
|---|---|---|---|
| Synaptigen | 20 mg probiotic blend | 3 species | CFU per strain; viable count at expiry |
| Claritox Pro | 112 mg | 4 botanicals | Individual doses; extract ratios |
| Vertigenics | 112 mg | 4 botanicals | Individual doses; extract ratios |
| Quietum Plus | 802 mg | 12 botanicals | Individual doses; extract ratios |
A proprietary blend is not automatically a red flag. Companies use them to protect formulations from copying, and some blends contain reasonable ingredients. The problem is that the buyer cannot audit the dose. If a blend contains ashwagandha, berberine, green tea extract or ginseng, the hidden amount affects both the evidence comparison and the interaction risk.
For a product aimed at a diagnosed or diagnosable condition, that uncertainty matters more. Vertigo, tinnitus and neuropathy all have treatable causes. A supplement that hides the active doses is a poor substitute for a clinical assessment, and it is harder to discuss with a pharmacist.
Claim-to-label mismatches
- Synaptigen: the reference page cites ingredients that are not in the product and links labels for two unrelated supplements. The sales story says probiotics travel to the brain and repair neurons, which is not established biology.
- Nerve Fresh: the page says there are no side effects, but passionflower, corydalis and California poppy can all be sedating. Some versions of the page mention vitamin and mineral support, while the label contains only five botanicals.
- iGenics: the AREDS2 comparison implies equivalence, but the vitamin E, zinc, lutein and zeaxanthin amounts differ. The vitamin E entry is internally inconsistent.
- Claritox Pro: the ototoxin explanation is not supported by the sources checked, and the same panel is sold under a different story as Vertigenics.
- Vertigenics: the dioxin-detox explanation is not supported, and the blend hides four botanical doses.
- Quietum Plus: the page says 18 plant extracts; the label lists a 12-item blend plus BioPerine. The "100% natural" badge is also inaccurate because the formula contains synthetic vitamins and minerals.
Refund documentation
A refund policy is not part of the Supplement Facts panel, but it is part of the buyer's documentation. We checked whether the window was stated consistently, who paid return shipping and whether an opened bottle was accepted.
| Product | Official window | Condition | Documentation issue |
|---|---|---|---|
| Synaptigen | 180 days from delivery | Return all bottles and packing slip; buyer pays shipping | Consistent |
| Nerve Fresh | 180 days | Return empty and unused portion; buyer pays shipping | Some pages say 60 days |
| iGenics | 180 days on sales page | No return needed on sales page; other pages differ | 60, 180 and 365-day terms |
| Claritox Pro | 60 days | Return all bottles; buyer pays shipping | Page advises 3 months of use |
| Vertigenics | 60 days | Return all bottles; buyer pays shipping | Page advises 3 months of use |
| Quietum Plus | 60 days | Return all bottles; buyer pays shipping | Label says at least 8 weeks |
The pattern is worth noticing: several products give a refund window shorter than the time the seller says results may take. That is not necessarily unlawful, but it shifts the risk to the buyer. If a page says "use for 90 days" and the guarantee is 60 days, ask support which term applies before ordering.
The 7-point label checklist
Use this before buying any supplement, not just the six in this audit.
- Find the serving size. A 60-capsule bottle with a two-capsule serving is a 30-day supply, not 60 days. Check whether the label's serving matches the price comparison you are making.
- Check every active dose. If an ingredient is listed without a milligram, microgram, CFU or IU amount, you cannot compare it with research or estimate risk.
- Count the proprietary blend. A blend total is not a dose. Note how many ingredients share it and whether any of them have known interaction thresholds.
- Look for strain and extract identity. "Lactobacillus" is a genus, not a strain. "Ginseng" is a plant, not an extract ratio. The more specific the identity, the more checkable the claim.
- Read the "other ingredients". Fillers, flavours and capsule materials matter for allergies, reflux and vegan diets. Peppermint oil and gelatin are common examples.
- Match the claim to the panel. If the page says 18 extracts and the label lists 12, that is a documentation problem. If the page says "no side effects" and the label contains sedating herbs, that is a safety problem.
- Confirm the refund in writing. Save the policy, the window, the return address and the support email before you pay. Do not rely on a badge or a third-party page.
What this audit cannot tell you
This is a documentation audit, not a laboratory test. We did not verify that the tablets or capsules contain the amounts printed, check for contamination, measure dissolution, or confirm the CFU count at expiry. Those questions require batch-specific certificates of analysis and independent testing, which none of the sellers published on the pages we checked.
We also cannot tell you whether a product will work for you. Label transparency is one input. The others are the quality of the evidence, your diagnosis, your medicines, your allergies and your clinician's advice. A product with a perfect label can still be a poor choice for a particular person.
Finally, the labels and seller terms can change. We checked them on 28-29 October 2026. Confirm the current panel and refund policy before ordering.
Frequently asked questions
What is a supplement label audit?
A label audit compares what a supplement page claims with what the Supplement Facts panel actually discloses. We check serving size, individual ingredient amounts, proprietary blends, strain or extract identity, other ingredients, and whether the marketing claims match the label.
Which label was the most transparent in this audit?
Nerve Fresh disclosed all five botanical doses and used no proprietary blend. iGenics also printed every active amount, but its vitamin E and zinc wording created internal consistency questions. Synaptigen was short and fully printed, but it did not break out probiotic CFU by strain.
Which label hid the most?
Quietum Plus disclosed 22 named label entries but placed 12 botanicals in an 802 mg proprietary blend with no individual doses. Its page also said 18 plant extracts while the label listed a 12-item blend plus BioPerine. Claritox Pro and Vertigenics each hid four botanicals in a 112 mg blend.
Does a transparent label mean the product works?
No. Label transparency only tells you what is in the bottle and whether the amounts are disclosed. It does not prove efficacy. A product can print every dose and still lack a clinical trial, and a product with a hidden blend can still contain useful ingredients.
Why do proprietary blends matter?
A proprietary blend gives a total milligram amount for several ingredients without individual doses. That prevents buyers and clinicians from comparing the formula with research doses, estimating interaction risk, or knowing which ingredient is doing the work.
What should I check before buying a sensory supplement?
Check the serving size, every active dose, whether a proprietary blend hides amounts, the strain or extract identity, the other ingredients, the claim-to-label match, and the refund terms. Confirm the checkout total and save the refund policy in writing.
