Neuvelys Ingredients: What the Label Actually Discloses

Why does magnesium appear twice on the Neuvelys label?

Does Neuvelys contain 160 mg of magnesium? The label does not establish that conclusion.

Does 80 mg of magnesium bisglycinate automatically equal 80 mg of elemental magnesium? No. A displayed compound weight and an elemental-magnesium declaration are not automatically interchangeable.

Are magnesium glycinate and magnesium bisglycinate definitely separate ingredients here? The label does not make that clear.

Magnesium glycinate or magnesium bisglycinate?

The nutrient panel declares 80 mg of magnesium ("as magnesium glycinate"), while the ingredient blend separately lists "magnesium bisglycinate — 80 mg". Because the label does not clarify the relationship, JeffsReviews does not resolve the ambiguity or conflate elemental amount with compound weight [1][5].

Where the applicable conditions of use are met, the only wording authorised in the EU register is: "Magnesium contributes to normal functioning of the nervous system" [3][4]. This normal-function claim does not establish that Neuvelys treats tinnitus, improves hearing or reduces distracting sounds.

Alpha-lipoic acid — 100 mg

What the label confirms: alpha-lipoic acid at 100 mg per capsule [1].

What it does not confirm: whether this is R-alpha-lipoic acid, a racemic mixture or sodium R-lipoate; stabilisation method; purity; manufacturing source; and any bioavailability system.

Research using a particular alpha-lipoic-acid form and amount cannot be assumed to apply directly when the product's form or study match is not established [9].

Butcher's broom root extract — 50 mg

Disclosed: common name butcher's broom, botanical species Ruscus aculeatus, plant part root, form extract, amount 50 mg [1].

Missing: extract ratio, extraction solvent, standardisation, ruscogenin content, drug-extract ratio, reference preparation and certificate of analysis.

Butcher's-broom research largely concerns particular root or rhizome preparations in circulatory contexts [7][10][11]. The European Medicines Agency identifies butcher's broom as Ruscus aculeatus root or rhizome [8], but a medicinal monograph does not establish that Neuvelys is a medicine or that its 50 mg preparation matches a medicinal extract.

L-carnitine — 10 mg

Disclosed: L-carnitine at 10 mg per capsule [1].

Not disclosed: whether the entry is L-carnitine base, L-carnitine tartrate, acetyl-L-carnitine or another delivery form; manufacturing source; purity.

Research on acetyl-L-carnitine or another specified carnitine form cannot automatically be applied to a label that states only "L-carnitine". A single case study using acetyl-L-carnitine in tinnitus is not treatment evidence for this 10 mg Neuvelys entry [12].

Turmeric rhizome extract — 10 mg

Disclosed: Curcuma longa, rhizome, extract at 10 mg standardised to 95% curcuminoids [1].

Missing: extract ratio, extraction solvent, carrier, particle technology, piperine or another absorption enhancer, product-specific absorption data and batch testing.

Standardisation identifies the proportion of curcuminoids in the stated extract. It does not by itself demonstrate absorption, clinical effectiveness or an ear-health benefit in the complete product.

Coenzyme Q10 as ubiquinone — 5 mg

Disclosed: Coenzyme Q10 as ubiquinone at 5 mg per capsule [1].

Missing: manufacturing source, carrier oil, solubilisation method, particle size, absorption technology, product-specific bioavailability and independent assay.

Human research using other CoQ10 amounts or preparations cannot be transferred automatically to the 5 mg ubiquinone entry in Neuvelys. A small older tinnitus pilot exists using higher CoQ10 amounts in a different population [13]; it was not a Neuvelys trial and does not prove that this product improves tinnitus.

What other ingredients are listed?

The supplied label lists the following excipients [1]:

• Vegetable capsule (hypromellose) — capsule shell.
• Microcrystalline cellulose — bulking agent.
• Magnesium salts of edible fatty acids — processing aid as labelled.
• Silicon dioxide — anti-caking agent.
• Stearic acid — processing aid.

The label does not disclose individual excipient quantities, and JeffsReviews does not invent them.

Does Neuvelys use a hidden proprietary blend?

The label uses the heading "Ingredient Blend," but it publishes a separate amount for each principal listed entry. This is more informative than a label that reveals only one combined blend total. However, publishing amounts does not resolve every formula question — several ingredient forms, extraction details, standardisations and manufacturing specifications remain undisclosed.

Assessment: amounts disclosed, preparation details incomplete.

Is Neuvelys vegan, gluten-free or allergen-free?

The merchant describes Neuvelys as suitable for vegans, and the label lists a vegetable hypromellose capsule [2]. JeffsReviews has not independently audited the manufacturing origin of every ingredient, processing aid or cross-contamination control.

The supplied label does not provide enough information for JeffsReviews to independently certify Neuvelys as gluten-free, allergen-free, dairy-free, soy-free or free from cross-contamination. Absence of a mention is not proof of absence.

Do these ingredients prove Neuvelys helps tinnitus or hearing?

No. An ingredient list does not by itself prove that the complete product improves tinnitus, hearing or ear-related discomfort.

• Ingredient presence is not finished-product evidence.
• Ingredient amount, preparation and combination effects all matter.
• Merchant testimonials are not clinical trials.
• An EU-authorised "normal nervous-system function" claim for magnesium [3][4] is not a tinnitus-treatment claim.
• Research using different formulations cannot automatically be transferred.
