# DigiproSpark > DigiproSpark is an independent supplement-review publication. Each product is scored with a published 5-Point Quality Filter (ingredient evidence, dosing and formula transparency, safety, value and guarantee, brand trust) and the verdict is published even when it is unfavourable. Reviews are written by Satwasheel Gharde, founder of Smiley Social. Content is educational, not medical advice. Some links are affiliate links and are disclosed on every page. 16 scored product reviews and 80 guides, comparisons, safety notes and tools are published; the most recent update was 2026-10-02. Corrections: smileysocial@digiprospark.com. ## How to read a verdict - Trust Score: a weighted 0-5 score. Weights: Ingredient Evidence 25%, Formula Transparency 20%, Safety & Tolerability 20%, Value & Guarantee 20%, Brand Trust & Manufacturing 15%. - Verdict tiers: 4.3-5.0 Recommended; 3.5-4.2 Recommended with Reservations; 2.5-3.4 Conditional; below 2.5 Not Recommended. - Critical-failure rule: a product whose Formula Transparency score is below 2.5 (typically doses hidden inside a proprietary blend) cannot score above Conditional, however high its average is. - Digital-audio programs are scored on a separate Digital Audio Score with different pillars, because dosing and label transparency do not apply to a digital track. - Reviews are research-based evaluations of labels, official sales pages and published studies. DigiproSpark does not run its own laboratory tests and does not claim a medical or clinical credential. ## Start here - [How we review (5-Point Quality Filter)](https://digiprospark.com/our-review-process/): the full scoring method, evidence grading and verdict tiers - [Editorial standards](https://digiprospark.com/editorial-standards/): research standards, corrections policy, AI-use policy and how products are chosen - [All reviews and guides](https://digiprospark.com/reviews/): the full index, filterable by category - [About DigiproSpark](https://digiprospark.com/about/): who runs the site and how it is funded - [Affiliate disclosure](https://digiprospark.com/affiliate-disclosure/): how affiliate commissions work and which products were declined - [Contact](https://digiprospark.com/contact/): questions, corrections and product requests ## Product reviews (highest Trust Score first) ### ProvaDent Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/provadent-review/ Trust Score: 3.3/5 (Conditional) Short answer: ProvaDent is a chewable oral-health supplement built around xylitol (900mg), a BioFresh enzyme complex (120mg, a blend of 3 enzymes with no per-enzyme breakdown), standardized cranberry extract (100mg, 30% PACs), purple carrot powder (100mg) and a 4-strain, 7-billion-CFU probiotic blend (50mg). Three of its five listed items are individually dosed (xylitol, cranberry, purple carrot) and two are combined-total-only blends (the enzyme complex and the probiotic) -- a real transparency edge over most products in this category, but not "nearly every ingredient," as we first wrote. Xylitol specifically has real, meta-analysis-level human evidence for cavity prevention, but that same research… Verdict: ProvaDent discloses more of its formula individually than most products in this review series, though not "nearly every ingredient" as we first described: its BioFresh enzyme complex and probiotic blend are combined-total-only, the same limitation most proprietary-blend products carry. Its headline ingredient, xylitol, has real, meta-analysis-level human evidence behind it for cavity prevention. But that same research shows the effective dose is considerably higher than what's actually in this product, the finished formula has no independent trial of its own, and its pricing is the same… ### GlucoBerry Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/glucoberry-review/ Trust Score: 3.2/5 (Conditional) Short answer: GlucoBerry is a capsule blood-sugar-support supplement built around Delphinol, a standardized maqui berry extract with a real published clinical trial behind it, plus chromium picolinate, biotin and gymnema sylvestre. Unlike several products in this category, GlucoBerry does not use a proprietary blend: the brand states every ingredient's amount individually. We could independently confirm two of those amounts (biotin, chromium) by cross-checking the label's own %DV figures, the others we could not independently verify beyond the brand's own disclosure. The finished formula has no independent clinical trial of its own, so we give it a Conditional verdict, not a pass. Verdict: GlucoBerry is a real supplement with a genuinely more transparent structure than most products we review, no proprietary blend, and real published trial data behind its headline ingredient, Delphinol. But the complete 4-ingredient formula has no independent trial, sources disagree on its guarantee length, and it carries two specific, real cautions (medication interaction risk, biotin lab-test interference), so under our own methodology it lands at Conditional rather than a passing score. Judge it on its genuinely disclosed ingredients and real ingredient-level evidence, with those two… ### ProDentim Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/prodentim-review/ Trust Score: 3.1/5 (Conditional) Short answer: ProDentim is a chewable-tablet oral probiotic combining a 20mg/3.5-billion-CFU proprietary blend of four bacterial strains (including a genuine, strain-matched Lactobacillus reuteri) with individually-dosed inulin (100mg). Oral probiotics as a category have real, published clinical trial support for gum health and bad breath, genuinely one of the stronger evidence bases among products in this category, and one of ProDentim's strains matches the exact strain used in published research. But per-strain doses inside the probiotic blend are undisclosed, and no independent trial of the complete ProDentim formula was identified. We give it a Conditional verdict, not a pass. Verdict: ProDentim is a real oral-probiotic supplement with a genuinely stronger evidence base than most products in this review series, its Lactobacillus reuteri strain appears matched to real published gum-health and halitosis research. But per-strain doses inside its core blend are undisclosed, the complete 4-strain formula has no independent trial, and third-party retail listings for it carry a specific, documented counterfeit risk. Under our own methodology it lands at Conditional, genuinely closer to a pass than most products we've reviewed, but not quite there. Buy only from the official site… ### Java Burn 2.0 Review (2026): Ingredients, Evidence, Side Effects & Honest Verdict URL: https://digiprospark.com/java-burn-review-ingredients-benefits-and-side-effects/ Trust Score: 3.0/5 (Conditional) Short answer: Java Burn is a stimulant-free, tasteless powder you stir into coffee, marketed for metabolism. Its ingredients, green tea, green coffee, L-carnitine, have modest individual research, but Java Burn hides the doses in a proprietary blend and the finished formula has no trial, so we give it a Conditional verdict, not a pass. Best for coffee drinkers with realistic expectations. Verdict: Java Burn is a legitimate, easy-to-use coffee add-on whose ingredients have real but modest research behind them. But its doses are hidden in a proprietary blend and the finished formula has no independent trial: so under our own methodology it earns a Conditional verdict, not a passing score. If your expectations are realistic and you buy from the official source, it is a reasonable optional add-on; if you want a proven shortcut, this is not one. ### Nagano Lean Body Tonic Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/nagano-tonic-review/ Trust Score: 3.0/5 (Conditional) Short answer: Nagano Lean Body Tonic is a low-caffeine daily greens, herb and probiotic powder for metabolism and weight support (the brand calls it stimulant-free, its green tea extract lists under 1% caffeine). Its label names 33 ingredients across five groups, and several have modest individual research: but the doses sit inside undisclosed proprietary blends and the finished formula has no clinical trial, so we give it a Conditional verdict, not a pass. Verdict: Nagano Lean Body Tonic is a real, fully-labelled (33-ingredient) supplement, but its key actives sit in undisclosed proprietary blends and the finished formula has no independent trial: so under our own methodology it earns a conditional verdict, not a passing score. Judge it as an optional daily greens/probiotic powder with a long guarantee window, on disclosed content and price rather than the marketing story. ### The Brain Song Review 2026: Does 40Hz Gamma Audio Really Work? URL: https://digiprospark.com/brain-song-review/ Trust Score: 3.0/5 (Conditional) Short answer: The Brain Song is a downloadable 12-minute MP3 audio track built around 40Hz gamma-frequency sound, marketed to improve focus, memory and mental clarity. The underlying gamma-brainwave science is real and comes from genuine MIT-led research, but that research is mostly in Alzheimer's-pathology mouse models and early-stage human Alzheimer's trials, not healthy adults seeking a focus boost, and the broader binaural-beat literature on healthy-adult cognition is mixed. Delivery and the ClickBank-backed refund are genuinely legitimate. We give it a Conditional verdict, real underlying science, unproven for the specific claim and audience being marketed to. Verdict: The Brain Song delivers exactly what it promises, a real 12-minute gamma-frequency audio file with a genuinely strong, processor-enforced refund guarantee, but its focus/memory claim leans on research done mostly in Alzheimer's-pathology models, not healthy adults, and no independent test of this specific track exists. Under our own methodology that lands it at Conditional: legitimate delivery, real underlying science, unproven for the specific claim and audience being marketed to. ### Gluco6 Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/gluco6-review/ Trust Score: 2.8/5 (Conditional) Short answer: Gluco6 is a capsule blood-sugar-support supplement combining three individually-dosed nutrients (vitamin D3, vitamin B1, chromium) with a 525mg proprietary blend of seven named ingredients, including a real stimulant compound (TeaCrine/theacrine) despite the brand describing the formula as stimulant-free. Several named actives have real, if mixed, human research for glycemic control, but the blend's per-ingredient doses are undisclosed and the finished formula has no independent clinical trial, so we give it a Conditional verdict, not a pass. Verdict: Gluco6 is a real, mostly-labelled (10-ingredient) supplement with a genuine transparency plus on three of its nutrients, but seven named actives sit in one undisclosed proprietary blend, the finished formula has no independent trial, and its marketing tone doesn't match the real stimulant (theacrine) inside it: so under our own methodology it earns a conditional verdict, not a passing score. Judge it as an optional daily blood-sugar-support capsule on disclosed content, real interaction risk and price rather than the marketing story. ### Moringa Magic Review 2026: Ingredients, Evidence, Side Effects & Honest Verdict URL: https://digiprospark.com/moringa-magic-review/ Trust Score: 2.8/5 (Conditional) Short answer: Moringa Magic is a single-ingredient moringa oleifera leaf capsule, no proprietary blend, which is a genuine transparency plus. Real 2025 clinical research exists on moringa oleifera and blood sugar/cardiometabolic markers, but the most rigorous recent synthesis (a 2025 meta-analysis) found the evidence inconsistent, not a reliable effect. We also found a potential gap worth flagging: the clinical trial with the clearest positive signal used 10 grams of moringa leaf powder per day, while third-party retail listings (not an official, independently-authenticated label) describe Moringa Magic's capsule dose at roughly 800mg (0.8g) per day, about 12 times lower if that listed figure is… Verdict: Moringa Magic is a real, single-ingredient supplement with a genuinely more transparent structure than a proprietary-blend product. But the real 2025 research on moringa oleifera, including the most rigorous recent meta-analysis, paints a more cautious picture than typical marketing copy, and we found a specific, checkable gap between the dose used in the clearest positive trial and what this capsule appears to deliver. Under our own methodology it lands at Conditional rather than a passing score. Judge it on its genuine single-ingredient simplicity and real research, with that dose gap in… ### The Genius Song Review 2026: Does This Audio Really Boost Focus? URL: https://digiprospark.com/genius-song-review/ Trust Score: 2.8/5 (Conditional) Short answer: The Genius Song is a 12-minute downloadable audio track (MP3, played with headphones) marketed for focus, creativity, and a "flow state," built around theta-wave brainwave entrainment. The official sales page states the target frequency plainly now; an earlier version of this review had flagged a theta-versus-gamma conflict in the marketing, and that conflict is gone. The research behind theta audio for creativity and mood is real but mixed, and EEG confirmation of the entrainment effect itself varies across studies. No independent test of this specific track exists. Delivery works, and the ClickBank refund is genuine. Our verdict is Conditional. Verdict: The Genius Song delivers a real, instantly-downloaded audio track with a genuinely strong, processor-enforced refund guarantee, but its creativity/focus claim rests on small-scale, mixed theta research, no independent test of this specific track exists, and its official sales page brands the product "The Genius Wave," not the name it's sold under here. Under our own methodology that lands it at Conditional: legitimate delivery, real but limited underlying research, and a genuine brand-naming gap. ### ProNail Complex Review 2026: Ingredients, Evidence, Price & Honest Verdict URL: https://digiprospark.com/pronail-review/ Trust Score: 2.7/5 (Conditional) Short answer: ProNail Complex is a topical micro-mist spray built around undecylenic acid and tea tree oil as its primary antifungal actives, the same two ingredients our Kerassentials review is built around, just in a spray rather than a brush-on applicator. Both have real, published research behind them: undecylenic acid is FDA-recognized under an OTC antifungal monograph, and tea tree oil has small clinical trials showing a real (if modest) improvement rate for nail fungus. What we could not find anywhere, the brand's own materials, third-party retail listings, or independent sources, is the actual concentration of either active in this specific spray. That's the main reason this lands Conditional… Verdict: ProNail Complex is built on two ingredients, undecylenic acid and tea tree oil, with genuine, checkable published evidence behind them, which is a real strength relative to many products in this category. But no concentration is disclosed for either, and no trial of the finished spray exists. Under our own methodology it lands at Conditional rather than a passing score. Judge it on its real ingredient-level evidence and spray-delivery convenience, with that transparency gap in mind. ### CogniCare Pro Review 2026: Ingredients, Side Effects, Price & Honest Verdict URL: https://digiprospark.com/cognicare-pro-review/ Trust Score: 2.6/5 (Conditional) Short answer: CogniCare Pro is a capsule nootropic built around named cognitive ingredients: Bacopa monnieri, Huperzine A, Rhodiola, L-Tyrosine, phosphatidylserine, acetyl-L-carnitine, green coffee bean extract and theobromine, among others. Several of these have real, individually-studied cognitive evidence, and Bacopa in particular has meta-analysis-level support. But specific per-ingredient doses are not disclosed in the sources we could find, and Huperzine A works via a genuine drug-like mechanism (the same enzyme some prescription Alzheimer's medications target) that carries a real interaction caution. We give it a Conditional verdict, not a pass. Verdict: CogniCare Pro is a real, consistently-named nootropic supplement with several genuinely well-researched ingredients (particularly Bacopa monnieri), but per-ingredient doses are undisclosed everywhere we looked, the finished formula has no independent trial, and Huperzine A's real drug-like mechanism deserves more caution than typical supplement marketing gives it: so under our own methodology it earns a conditional verdict, not a passing score. Judge it as an optional nootropic capsule on disclosed ingredient names, real interaction risk and price rather than the marketing story. ### DentaBiome Review 2026: Ingredients, Evidence, Price & Honest Verdict URL: https://digiprospark.com/dentabiome-review/ Trust Score: 2.6/5 (Conditional) Short answer: DentaBiome is a berry-flavored chewable tablet built around postbiotics rather than the live-bacteria probiotics used in products like ProDentim: meaning it delivers ready-made bioactive compounds (organic acids, antimicrobial peptides, enzymes) instead of bacteria that need to colonize the mouth. That's a genuinely different, defensible mechanism, not a lesser one. But the brand's own materials describe the core "Postbiotic Complex (including a FabM enzyme)" as a proprietary blend, meaning we can't verify how much of the actual active ingredient a single tablet delivers. Combined with the fact that no clinical trial of the finished DentaBiome product has been published, that's the main… Verdict: DentaBiome takes a genuinely different, legitimate approach to oral health, postbiotics instead of live probiotics, and a 2025 systematic review found that approach promising for dental caries specifically. But the product's own core complex has an undisclosed strength, and no trial of the finished chewable exists. Under our own methodology it lands at Conditional rather than a passing score. Judge it on its genuine mechanism difference and real research, with that transparency gap in mind. ### Kerassentials Review 2026: Ingredients, Evidence, Price & Honest Verdict URL: https://digiprospark.com/kerassentials-review/ Trust Score: 2.6/5 (Conditional) Short answer: Kerassentials is a topical oil blend of 8 ingredients, Tea Tree Oil, Lavender Oil, Organic Flaxseed Oil, Almond Oil, Lemongrass Oil, Aloe Vera, Tocopheryl Acetate (Vitamin E) and Undecylenic Acid, applied daily to the nail and surrounding skin. The strongest evidence anchor in the formula is undecylenic acid, an FDA over-the-counter monograph-recognized antifungal active with decades of documented use. Tea tree oil also has real but modest clinical trial data, at 100% concentration, applied twice daily for 6 months, one randomized trial found an 18% mycological cure rate. The catch: Kerassentials discloses no concentration or dose for any of its 8 ingredients, so neither of those trial… Verdict: Kerassentials is a real topical product built around one genuinely well-established antifungal active (undecylenic acid) and one modestly-studied one (tea tree oil): but it discloses the concentration of neither, which is the central, checkable gap in this entire review. A direct category competitor (Funginix) does disclose its active's concentration, which makes this gap concrete rather than a generic complaint. Under our own methodology, that transparency gap caps Kerassentials at Conditional rather than a passing score. Judge it on its real ingredient anchors, with that… ### TonicGreens Review 2026: Ingredients, Evidence, Safety & Honest Verdict URL: https://digiprospark.com/tonicgreens-review/ Trust Score: 2.5/5 (Conditional) Short answer: TonicGreens is a daily greens powder built from four proprietary blends, an immune-support mushroom complex (reishi, shiitake, maitake), an antioxidant trio (quercetin, curcumin, resveratrol), a greens/detox blend, and a prebiotic/probiotic blend. Per-ingredient doses are not disclosed for any of them, only each blend's combined total, the same transparency limitation that caps our Nagano review. We also found a genuine mismatch: the clearest positive human trial for its antioxidant trio (quercetin, curcumin and resveratrol together) was a Phase II trial for age-related macular degeneration, not the general immune/antioxidant support this product is marketed for. Both the hidden doses and… Verdict: TonicGreens is a real, widely sold greens powder covering four genuine functional categories with some real ingredient-level research behind it. But all four blends hide individual doses, and the clearest positive trial for its antioxidant trio was actually for a different health condition than the one marketed. Under our own methodology, both the hidden doses and that trial mismatch keep it at Conditional rather than a passing score. Judge it on its genuine ingredient variety and real (if mismatched) research, with the transparency gap in mind. ### ZenCortex Review 2026: Ingredients, Evidence & Honest Verdict URL: https://digiprospark.com/zencortex-review/ Trust Score: 2.4/5 (Not Recommended) Short answer: ZenCortex is a liquid supplement marketed for tinnitus relief, hearing support, and mental clarity, built around 20+ plant-based ingredients including grape seed extract, green tea, Gymnema Sylvestre, Panax ginseng, and maca root. Some third-party marketplace listings describe it as ear drops; the official sales page and a customer testimonial confirm it's actually an oral liquid, taken by mouth, which also matches its metabolic and energy-focused ingredients like chromium picolinate, raspberry ketones, and African mango. No major medical body recommends any dietary supplement for tinnitus specifically, and this is our first Not Recommended verdict in the Brain & Focus category alongside… Verdict: ZenCortex joins Audifort as our second Not Recommended verdict in this category, for related but distinct reasons: no ingredient has tinnitus-specific evidence, the formula is completely undisclosed, its usage instructions genuinely conflict across sources, and its "non-stimulant" claim is contradicted by its own ingredient list. The American Academy of Otolaryngology's own clinical guideline sets the bar this product, like every supplement we've checked against it, fails to clear. If you're dealing with tinnitus or hearing changes, a doctor or audiologist is the right first step, not this… ### Audifort Review 2026: Ingredients, Evidence & Honest Verdict URL: https://digiprospark.com/audifort-review/ Trust Score: 2.2/5 (Not Recommended) Short answer: Audifort is a liquid drops supplement marketed for hearing support and tinnitus (ringing in the ears) relief, built around 20+ plant-based ingredients including maca root, grape seed extract, green tea, capsicum and GABA. The single most important thing to know: the American Academy of Otolaryngology-Head and Neck Surgery's clinical practice guideline explicitly states clinicians should NOT recommend dietary supplements for persistent tinnitus, and no supplement has demonstrated reliable efficacy for it in peer-reviewed trials: a standard even the most-studied supplements (ginkgo, zinc, melatonin) fail to meet. None of Audifort's specific ingredients are among even those… Verdict: Audifort is a real, sold liquid supplement, but its central marketed claim, hearing and tinnitus support, runs directly against the American Academy of Otolaryngology's own clinical practice guideline, which explicitly advises against dietary supplements for tinnitus because none has demonstrated reliable efficacy. None of Audifort's specific ingredients have been studied for this claim at all. Under our own methodology, that combination earns a Not Recommended verdict, our most skeptical verdict in this review series, reflecting a genuinely weak evidence picture, not a fraud accusation.
