# NutriAudit Review AI supplement stack analyzer that flags duplicate ingredients, upper-limit risks, and documented interactions for free, with a $4.99 ## Editor's Score: 71/100 Value scores high because $4.99 one-time with a no-charge-on-failure guarantee is genuinely fair pricing for what the paid report delivers, and the free tier does real substantive work. Ease of use scores well given no sign-in required to start, label photo scanning, and a clean two-tier structure with no hidden upsells. Capability is held back by the hard dataset ceiling of 25+ interaction pairs and the complete absence of drug-supplement interaction checking, a gap that two or more named reference tools in the broader category cover. Delivery lands in the low teens because no third-party user sentiment could be found to validate the tool's claims, the dataset scope disclaimer is significant, and the iterative-audit pricing model (every stack change costs a new $4.99 credit) creates a friction pattern that could frustrate the users most likely to need repeated checks. ## Pros - One-time $4.99 audit credit with no subscription and a genuine no-charge-on-failure guarantee makes the full report accessible without financial risk. - Covers five regional safety standards (US FDA, EU EFSA, AU TGA, CN CNS, JP MHLW) and cites NIH ODS, NASEM, EFSA, and NHMRC, giving the reference layer real credibility for a consumer tool. - Free tier does substantive work: up to 15 supplements per stack, duplicate and upper-limit checks, and interaction warnings without requiring sign-in to start. ## Cons - Coverage is hard-capped at verified dataset entries: any ingredient without a confirmed reference record gets no analysis, and the interaction checker covers only 25+ known pairs, which is a narrow slice of possible supplement combinations. - No drug-supplement interaction checking at all, which is a significant gap for the large share of supplement users who also take prescription or OTC medications. - The free tier caps at 15 supplements per stack, and adding or removing even one product or changing a dose counts as a new audit requiring a fresh $4.99 credit, so iterative stack optimization gets expensive quickly. ## Pricing Freemium. A free tier is available. - Free Automated Screening: $0 - Personal Stack Review: $4.99 Pricing reflects what we saw at the time of review (2026-11). Confirm current pricing on the official site.

Directory: https://aitoolseekers.com This review: https://aitoolseekers.com/tools/nutriaudit Methodology: https://aitoolseekers.com/how-verification-works ## Verdict NutriAudit is the clearest option for someone juggling five or more supplements who wants a structured, citation-backed safety screen before their next doctor visit. The free tier does real work, and the $4.99 one-time audit is priced low enough that the barrier to a full report is almost zero. The dataset covers 25+ interaction pairs and five regional standards, which is genuinely useful but also a hard ceiling: anything outside that verified dataset gets no coverage, and there is no drug-supplement interaction checking at all. Best for: Self-managing supplement users who want a cited, structured stack review before consulting a professional Not for: Anyone needing drug-supplement interaction checks or a clinical-grade analysis tool ## Overview NutriAudit is a web-based supplement stack analyzer built around one specific problem: people taking multiple vitamins and supplements rarely know how the combined doses, overlapping ingredients, and documented interactions add up across all their labels. The tool lets you add products or scan a label photo, then totals combined daily doses, flags duplicate ingredients (including aliases like ascorbic acid and vitamin C), compares intake against regional upper limits, and lists documented supplement-to-supplement interactions. It cites NIH ODS, NASEM, EFSA, and NHMRC as reference sources, and covers five regional safety standards: US FDA, EU EFSA, AU TGA, CN CNS, and JP MHLW. The product splits into two layers. The free automated screening handles up to 15 supplements per stack and produces a NutriAudit Audit Progress Score alongside duplicate and upper-limit risk checks and recorded interaction warnings. The $4.99 one-time Personal Stack Review goes further: it orders risks by priority, adds product-by-product dose context, surfaces evidence gaps, and generates questions formatted for review with a qualified professional. Critically, the credit is only consumed after a report successfully generates, so a failed generation does not cost you. Beyond the main audit, NutriAudit offers five standalone free tools: a Supplement Stack Safety Checker, a Supplement Interaction Checker (covering 25+ known pairs), a Duplicate Ingredients Checker, a Dosage Comparison Tool, and a Supplement Toxicity Checker. These are pairwise or manual tools rather than full-stack analyses, but they are genuinely useful for quick spot-checks without committing to a full audit. The honest limitation is dataset scope. Coverage is restricted to ingredients with verified entries in the reference dataset, so anything outside that boundary gets no analysis. The tool is explicit that it does not check drug-supplement interactions and is not a substitute for medical advice. For a consumer-facing safety screen, that transparency is appropriate. For anyone on prescription medications, it is a real gap. ## Who should use it NutriAudit fits the person who has accumulated a shelf of supplements over time and genuinely does not know whether their combined daily intake of, say, vitamin D, magnesium, and a multivitamin is pushing past safe upper limits. It is also well suited to someone preparing for a GP or dietitian appointment who wants to arrive with a structured, cited summary rather than a bag of bottles. The $4.99 price point means even casual users can afford the full report without committing to a subscription. Anyone on prescription medications should look elsewhere first: NutriAudit does not check drug-supplement interactions, which is often the more clinically urgent question. For that use case, a pharmacist consultation or a tool specifically built for drug interaction checking is the right move. Within the directory, neither Simple Muscle nor PawCoach addresses supplement safety, so there is no direct competitor here to redirect to; the honest answer is that a qualified pharmacist or dietitian covers the drug-interaction gap NutriAudit leaves open. ## FAQ Q: Is NutriAudit a subscription service? A: No. The Personal Stack Review is a one-time payment of $4.99 per audit credit with no automatic renewal. The free automated screening has no cost at all. Q: What happens if the report fails to generate? A: The credit is only consumed after a successful report is saved. A failed generation returns the credit, so you are not charged for a report you did not receive. Q: Does NutriAudit check interactions between supplements and prescription drugs? A: No. NutriAudit checks supplement-to-supplement interactions only, covering 25+ known pairs. It does not check drug-supplement interactions, which is a meaningful limitation for anyone on prescription or OTC medications. Q: How many supplements can I include in a stack? A: The free tier supports up to 15 supplements per stack. The pricing page does not state a higher cap for the paid audit, so 15 appears to be the current stack limit regardless of tier. Q: What counts as a new audit requiring a new credit? A: Adding or removing a product, changing an ingredient or dose, or changing the regional standard all create a new audit fingerprint and require a fresh $4.99 credit. Q: Which reference bodies does NutriAudit cite? A: NutriAudit cites NIH ODS, NASEM, EFSA, and NHMRC, and applies safety standards from five regional authorities: US FDA, EU EFSA, AU TGA, CN CNS, and JP MHLW. Coverage is limited to ingredients with verified entries in the current dataset.
