DigiproSpark’s Complete Product Roundup 2026: Every Reviewed Supplement, By Category

This page used to be framed as a “Top 10 supplements for energy and focus.” We rewrote it because that framing no longer matches what DigiproSpark actually covers, our current roster spans several categories, not just energy and focus, and several of the products in it are not primarily energy/focus products at all. Rather than force a mismatched “Top 10” list, here’s an honest, category-by-category roundup of every product we currently review, with a real link to the full review and our actual Trust Score verdict for each, including the ones that don’t score well.

A note on what “Trust Score” means: every product below is scored 0–5 across five weighted checks (Ingredient Evidence, Formula Transparency, Safety, Value & Guarantee, Brand Trust), then placed in a tier: 4.3–5.0 Recommended, 3.5–4.2 Recommended with Reservations, 2.5–3.4 Conditional, below 2.5 Not Recommended. Full methodology: Our Review Process. As of this rewrite, every product below lands Conditional or lower: we have not yet found a product in our current roster that clears the bar for an unqualified Recommended verdict, and we say so plainly rather than inflate scores to look more positive.

Weight & Metabolic

Our flagship category, and the only one with two products carrying a combined recurring price point (~$64.88) in our records.

• Nagano Lean Body Tonic: Trust Score 3.0/5, Conditional. A 33-ingredient greens/herb/probiotic powder, several named ingredients have real research, but doses sit inside undisclosed proprietary blends.
• Java Burn: Trust Score 3.0/5, Conditional. A coffee-additive metabolism blend with the same proprietary-blend transparency limit as Nagano.

Blood Sugar

A newer category for us (~$110.30 combined recurring), covering two capsule-based blood-sugar-support products.

• Gluco6: Trust Score 2.8/5, Conditional. Real evidence exists for several named actives, but we found a genuine gap between its “stimulant-free”-style marketing and a real stimulant compound (theacrine) in its blend.
• GlucoBerry, Trust Score 3.2/5, Conditional, the closest to a pass of our two blood-sugar products. No proprietary blend, and its headline ingredient (Delphinol maqui berry extract) has real published trial data behind it.

Brain & Focus

Our most varied category: two brainwave-entrainment audio tracks and two capsule-based nootropics, each evaluated on its own terms since they work through completely different mechanisms.

• The Brain Song: Digital Audio Score 3.0/5, Conditional (a dedicated methodology for digital audio products, not the supplement Trust Score used above, see our methodology). A real 12-minute gamma-frequency audio track, the underlying science is genuine but mostly studied in Alzheimer’s-pathology models, not healthy-adult focus.
• The Genius Song: Digital Audio Score 2.8/5, Conditional. A theta-frequency audio track, confirmed directly on the official sales page, which currently brands the product “The Genius Wave.”
• CogniCare Pro: Trust Score 2.6/5, Conditional. Contains Bacopa monnieri (real meta-analysis-level evidence) and Huperzine A, a genuinely potent, drug-like ingredient that deserves more caution than typical supplement marketing gives it.
• Audifort, Trust Score 2.2/5, Not Recommended for its core hearing/tinnitus claim. Major clinical guidelines explicitly advise against supplements for tinnitus, and none of its ingredients have direct hearing-outcome research, our most skeptical verdict in this roundup.
• ZenCortex, Trust Score 2.3/5, Not Recommended, for the same core reason as Audifort, plus a genuine, unresolved conflict in its own usage instructions (oral vs. ear drops) and a “non-stimulant” claim contradicted by its own disclosed guarana. See our direct Audifort vs ZenCortex comparison.

Oral & Dental Health

A newer category (~$43.64 combined recurring) covering three oral-health products with genuinely different mechanisms.

• ProDentim, Trust Score 3.2/5, Conditional. Its Lactobacillus reuteri strain appears matched to real published gum-health research, one of the stronger single-ingredient matches in our entire roster.
• ProvaDent, Trust Score 3.3/5, Conditional, the highest score in this roundup. Most (not all) of its ingredients are individually dosed, and its headline ingredient (xylitol) has real meta-analysis-level evidence, though at a higher dose than what’s actually in the product.
• DentaBiome, Trust Score 2.6/5, Conditional. A postbiotic chewable, a genuinely different mechanism from ProDentim’s live-bacteria probiotic, but its core complex is an undisclosed proprietary blend and no finished-product trial exists yet.

Energy & Nail/Skin Health

Both reintroduced with fresh research after a temporary removal tied to a technical issue on each product’s page, plus a new addition to the nail/skin silo.

• Moringa Magic: Trust Score 2.8/5, Conditional. A single-ingredient moringa oleifera capsule with real 2025 clinical research behind the ingredient, but a genuine, checkable gap between the studied dose and what the capsule appears to deliver.
• Kerassentials, Trust Score 2.6/5, Conditional. A topical oil built around undecylenic acid (an FDA OTC-recognized antifungal active) and tea tree oil, but it discloses no concentration for any of its 8 ingredients, a real, checkable transparency gap.
• ProNail Complex: Trust Score 2.7/5, Conditional. A spray-format alternative built on the same two evidence-backed actives as Kerassentials (undecylenic acid, tea tree oil), also with no disclosed concentration. See our direct ProNail Complex vs Kerassentials comparison.

Immune & Greens

Our fourth-largest category by ingredient count: a greens/mushroom/antioxidant powder built around a genuinely well-studied mushroom mechanism, evaluated on the same undisclosed-blend-dose standard as every other product in this roundup.

• TonicGreens, Trust Score 2.5/5, Conditional. Real 2023 human-trial evidence exists for its reishi/shiitake/maitake beta-glucan mechanism, and its antioxidant trio (quercetin, curcumin, resveratrol) has genuine clinical trial support, for age-related macular degeneration specifically, not the general immune/antioxidant support it’s marketed for. All four of its blends disclose combined totals only, no individual ingredient doses.

A note on YouthRX: this product was fully removed from the site (not a temporary technical issue) after its ClickBank/Digistore24 offer went permanently sold out: confirmed against the current affiliate export, which no longer lists it. It won’t be relisted in this roundup unless a real, verified replacement offer is sourced, per our standing policy against linking an affiliate offer we can’t confirm is live.

Why So Many “Conditional” Verdicts?

If you’ve read several of our reviews, you’ll notice “Conditional” (and now, with Audifort, “Not Recommended”) shows up far more often than an unqualified “Recommended.” That’s not an accident or a house style, it’s what our 5-Point Quality Filter actually finds when doses sit inside proprietary blends, when a finished formula has no independent clinical trial of its own, or, for Audifort specifically, when a product’s core marketed claim runs against standing clinical guidance. We’d rather publish an honest “Conditional” than inflate a score to make a page read better. See Proprietary Blends Explained and How We Grade Supplement Evidence (A–U) for the full reasoning behind this.
