| +13 | NSF/ANSI 455-2 GMP facility certification verified for the current Nature's Way manufacturing platform that now carries legacy Enzymatic Therapy products. NSF's current listing shows Nature's Way and Integrative Therapeutics facilities in Green Bay, Wisconsin, under NSF/ANSI 455-2 dietary supplement GMP, including 825 Challenger Drive and 3466 East Mason Street, with capsule, liquid, powder, soft gel, tablet, gummy, packaging, quality unit, and warehousing scopes. Awarding the upper middle of the +10 to +15 range because multiple relevant facilities and product technologies are listed, but this is facility GMP certification rather than product-level NSF Certified for Sport. 3, 4, 5 Current listing reviewed in 2026. Full weight. · full weight |
| +10 | ISO 17025 in-house testing capability disclosed. Nature's Way says its state-of-the-art lab meets international ISO 17025 standards, is annually audited, and performs identity, purity, potency, composition, contaminant, microbiology, physical, and stability testing. Awarding +10 within the +8 to +12 range because the lab capability is unusually specific for a mass-market supplement company, but the public page does not provide batch-level numerical COAs for Enzymatic Therapy lots. 1, 2 Current official quality pages reviewed in 2026. Full weight. · full weight |
| +8 | Testing from formulation to finish and FDA and CFIA dietary supplement compliance are disclosed. Nature's Way states every supplement is tested from formulation to finish and meets FDA and CFIA requirements for supplements in the United States and Canada. Awarding +8 for broad testing disclosure, below the high end because this is primarily company-disclosed testing rather than a comprehensive public COA program. 1, 6 Current official pages reviewed in 2026. Full weight. · full weight |
| +5 | Contaminant, heavy metal, residual chemical, and microbiology testing are explicitly disclosed. The quality portal states contaminant testing checks regulated limits for bacteria, heavy metals, and residual chemicals, while the Herb Check page lists analytical, microbiology, physical, and stability testing. Awarding +5, combining the rubric's +3 to +6 contaminant and microbiological testing positives without double counting the ISO 17025 adjustment. 1, 2 Current official pages reviewed in 2026. Full weight. · full weight |
| +4 | Ingredient identity and potency methods are disclosed for at least some products. The DGL Ultra ingredient page describes HPTLC botanical fingerprinting against certified botanical reference standards, and the general testing portal describes identity, potency, and composition testing. Awarding +4 because the method disclosure is meaningful, but coverage appears product or ingredient page dependent rather than a complete lot-level database. 2, 48 Current official pages reviewed in 2026. Full weight. · full weight |
| — | Not scored I did not find a public Enzymatic Therapy batch COA portal, product-level NSF Certified for Sport listing, USP Verified product listing, or current FDA inspection record specific to Enzymatic Therapy products. The analysis relies heavily on current Nature's Way and Schwabe evidence because Enzymatic Therapy is now operated under that platform. |
| Formulation baseline 50 → 68 Mixed |
| +6 | Branded and clinically studied ingredients are present in multiple sampled legacy products. Examples include GutGard DGL licorice in DGL and DGL Ultra, BB536 and NCFM probiotic strains in Pearls Acidophilus, and labeled allicin delivery in Garlinase 5000. Awarding +6 within the +5 to +8 branded premium ingredient range because this pattern appears in several flagship products, but not enough evidence was found to prove it across the whole Nature's Way or Enzymatic Therapy line. 8, 9, 12, 13, 14 Current labels and ingredient evidence reviewed in 2026. Full weight. · full weight |
| +6 | Effective dosing appears in several sampled products, but not a verified majority of the line. Pattern calculation: 4 of 9 sampled legacy products had clearly research-aligned or market-standard doses based on public labels and evidence reviewed: DGL or DGL Ultra with GutGard at a label pattern consistent with 75 mg twice daily, Pearls Acidophilus with 1 billion CFU and named strains, Garlinase 5000 with 5,000 mcg allicin, and Pearls Complete with named multi-strain probiotic delivery. The rubric gives +10 to +15 for majority-line effective dosing. Because the verified pattern is about 44 percent, applying roughly 44 percent of a +14 midpoint gives +6. 8, 9, 10, 12, 13, 14 Current labels and clinical ingredient evidence reviewed in 2026. Full weight. · full weight |
| +8 | Delivery technology appears in multiple sampled products. Pearls uses a triple-layer coating intended to protect probiotics from heat, air, moisture, and stomach acid, Garlinase 5000 is enteric coated to survive stomach acid and release in the small intestine, and DGL products use chewable formats for local digestive use. Awarding +8 at the low end of the +8 to +12 bioavailability or delivery technology range because the technologies are practical and repeated in the digestive line, but no independent head-to-head bioavailability data for current lots was found. 11, 12, 14, 19 Current product pages reviewed in 2026. Full weight. · full weight |
| +5 | Some synergistic or multi-ingredient formulations are plausibly researched, but product-specific public clinical trials were not found. Examples include Cell Forte MAX3 combining IP-6, inositol, maitake, and cat's claw, CompleteGest as a broad-spectrum digestive enzyme blend, and Mega-Zyme as a digestive and systemic enzyme product. Awarding +5 within the +5 to +8 range because the rationale is clear, but the public evidence is mostly ingredient or category based rather than brand-product clinical trials. 16, 17, 18, 19, 44 Current product pages and recent enzyme evidence reviewed in 2026. Full weight. · full weight |
| −3 | Limited proprietary-blend opacity appears in sampled products. Pattern calculation: at least 2 of 9 sampled legacy products used blend-style disclosure or did not clearly expose every active amount in a shopper-friendly way, including Pearls Acidophilus showing an 11 mg proprietary probiotic blend while still listing strains and CFU, and Cell Forte MAX3 using a combination structure where some support claims are not tied to fully transparent public clinical dosing. Full rubric penalty for widespread proprietary blends is -12 to -18. The observed pattern is about 22 percent of the sample, so 22 percent of a -15 midpoint is -3.3, rounded to -3. 12, 16, 27 Current labels reviewed in 2026. Full weight. · full weight |
| −4 | Some structure-function claims are stronger than the publicly visible product-specific evidence. Pattern calculation: Cell Forte MAX3 and Mega-Zyme make natural killer-cell activity, immune, muscle soreness, or systemic enzyme support claims, but the strongest public evidence found was ingredient or category level, not direct trials on current Enzymatic Therapy or Nature's Way products. This is 2 of 9 sampled products, or about 22 percent. Applying roughly 22 percent of the -12 to -18 claims-without-evidence range gives about -3 to -4, scored as -4 because immune and systemic enzyme claims are higher-stakes than basic digestive comfort claims. 16, 17, 19, 20, 44 Current product pages and recent clinical context reviewed in 2026. Full weight. · full weight |
| — | Not scored I sampled major legacy products visible in current retail and Nature's Way pages, but did not complete a comprehensive line audit of every historical Enzymatic Therapy SKU. I did not find product-specific randomized trials on current finished products, only ingredient and category evidence. |
| Transparency baseline 50 → 82 Strong |
| +8 | Ownership and parent-company structure are disclosed. Schwabe Group lists Nature's Way under Schwabe North America in Green Bay, and North Castle states Enzymatic Therapy was sold to Schwabe Pharmaceutical Group in October 2008. Awarding +8 within the +8 to +12 ownership disclosure range because the chain is clear, although Enzymatic Therapy's current brand identity is partly absorbed into Nature's Way rather than presented as a standalone company. 4, 5 Current ownership pages reviewed in 2026, with 2008 transaction history used as historical context. Full weight for current ownership clarity. · full weight |
| +8 | Manufacturing locations and facility certifications are disclosed through official and certifier sources. NSF lists Green Bay facilities and the Schwabe Group page lists Schwabe North America at 825 Challenger Drive, Green Bay. Awarding +8 because the locations and certification scope are verifiable, but the shopper still cannot map every Enzymatic Therapy lot to a specific facility from the public label alone. 3, 4 Current NSF and Schwabe pages reviewed in 2026. Full weight. · full weight |
| +8 | Testing disclosures are unusually detailed for a non-COA brand. The quality portal explains identity, purity, potency, composition, contaminant, in-process, finished-product, and stability testing, while the Know What's In Your Bottle page states Nature's Way requires raw material COAs and retests ingredient batches received. Awarding +8 in the testing-disclosure range because this is stronger than generic GMP language, but it is not a broad public numerical COA system. 1, 2 Current official pages reviewed in 2026. Full weight. · full weight |
| +5 | Ingredient sourcing process is partially disclosed. Nature's Way says it has sourced ingredients from partners around the world since 1969, requires every raw material to come with a certificate of analysis, and still tests each ingredient batch received. Awarding +5 as partial sourcing transparency because supplier identities, countries of origin by SKU, and batch-level supplier documents are not broadly public. 2 Current official page reviewed in 2026. Full weight. · full weight |
| +3 | Subscription terms are clearly presented on product pages. Several Nature's Way product pages state that customers enrolling in Subscribe & Save agree to recurring charges and may cancel, pause, or modify any time. Awarding +3 at the low end of the +3 to +5 no-hidden-subscription factor because the terms are visible, but I did not perform a cancellation test. 14, 18, 19 Current product pages reviewed in 2026. Full weight. · full weight |
| — | Not scored No direct response from customer service was obtained, no cancellation test was performed, and no Enzymatic Therapy lot-specific COA was located. Product-to-facility mapping for each lot was not publicly available. |
| Safety baseline 90 → 72 Adequate |
| −8 | Historical FDA injunction and injury reports, heavily time discounted. According to a republished FDA Consumer article, a 1992 consent decree of permanent injunction followed a six-year FDA investigation prompted by reports of serious injuries and a death after use of products then manufactured by Enzymatic Therapy. The company signed the consent decree without admitting violations. Base severity chosen as -30 because this resembles a serious FDA enforcement action with reported harm, but it is more than 30 years old, so the rubric's 10+ year 25 percent temporal weight gives -7.5, rounded to -8. 24 1992 event, more than 10 years old. 25 percent temporal weight applied. · 25% weight |
| −3 | 1994 CPSC recall for iron product lacking child-resistant packaging. CPSC reported about 4,435 bottles of Fem-Plus with 25 mg iron per capsule were recalled because the bottles lacked required child-resistant packaging, creating a risk that a child could ingest too much iron and become seriously ill or die. Base severity chosen as -10 because it was a packaging-related safety recall with potentially severe pediatric risk but limited unit scope and a remedy. Applying 25 percent weight for 10+ years old gives -2.5, rounded to -3. Safety issues are scored even when isolated. 23 1994 recall, more than 10 years old. 25 percent temporal weight applied. · 25% weight |
| −6 | 2018 liver cleanse class action was filed and later resolved by confidential settlement and stipulated dismissal. The complaint alleged Enzymatic Therapy deceptively advertised Ultra Liver Cleanse and Complete Liver Cleanse as removing toxins and cleansing or rejuvenating the liver. Defense counsel later reported a confidential settlement and stipulated dismissal after moving to dismiss and before discovery, and PacerMonitor shows the case was dismissed with prejudice in October 2018. Base class-action severity chosen as -15, reduced for settlement before discovery and no court finding of liability located. Event is 5 to 10 years old, so 50 percent temporal weight gives about -6 to -7, scored as -6. 25, 26, 27 2018 case, about 8 years old. 50 percent temporal weight applied. · 50% weight |
| −5 | Recent parent-platform voluntary recall context. A retailer recall notice reported selected Nature's Way Sambucus Organic Elderberry Syrup batches were voluntarily recalled due to a quality issue that could cause bloated bottles with noticeable pressure when opening. This was not an Enzymatic Therapy product, so the base penalty is low, but it is relevant to the current Nature's Way platform. Base -5 for minor voluntary recall handled through recall notice, full recency weight because it was reported in 2025, scored -5. 47 2025 recall notice, within 2 years. Full temporal weight applied. · full weight |
| +4 | Proactive safety measures disclosed. Nature's Way discloses contaminant, microbiology, identity, potency, stability, raw material COA, and ISO 17025 lab systems. Awarding +4 within the +3 to +6 proactive safety measures range because the controls are meaningful, but not all Enzymatic Therapy batches are independently verifiable by public COA. 1, 2 Current official pages reviewed in 2026. Full weight. · full weight |
| — | Not scored The 1992 FDA enforcement source located was a republished FDA Consumer article rather than a primary court docket. I did not locate a complete current FDA inspection history for the Nature's Way facilities, and I did not locate a current FDA recall entry specific to Enzymatic Therapy products. |

| +10 | Probiotic Pearls pricing is fair to good versus mainstream probiotic comparables, with a caveat about CFU differences. Walgreens lists Enzymatic Therapy Acidophilus Pearls 90 count at $39.99, or $0.44 per softgel, and Walmart lists a 2 pack of 30 count at $28.15, or about $0.47 per softgel. Culturelle Digestive Daily is $17.99 for 30, or $0.59 per count, and Align 70 Billion is $34.98 for 30, or $1.17 per count. Because Pearls is cheaper per serving but lower CFU than some comparables, awarding +10 rather than the full +12 to +18 below-market adjustment. 30, 31, 32, 33 Current 2026 retail pricing. Full weight. · full weight |
| +12 | Quality and certification partly justify mid-tier pricing. The Nature's Way platform has NSF GMP facility certification and ISO 17025 lab claims, which support a premium over no-name commodity products. Awarding +12 at the low end of the +12 to +18 premium-justified range because the quality infrastructure is credible, but batch-level COAs and product-level certifications were not found for most Enzymatic Therapy products. 1, 2, 3 Current 2026 quality and certification evidence. Full weight. · full weight |
| +8 | Transparent pricing and discounts are visible. Product pages show one-time prices, Subscribe & Save 15 percent pricing, recurring-charge language, cancellation or pause language, and free shipping on United States orders over $49. Awarding +8 within the +6 to +10 transparent-pricing or subscription-value range because discounts are straightforward and no hidden fee pattern was found, but cancellation was not tested. 14, 18, 19 Current 2026 product pages. Full weight. · full weight |
| −5 | DGL value is weaker than some commodity DGL alternatives. Nature's Way DGL is listed at $19.49 for 100 chewables with directions of 6 tablets daily, or roughly 16.7 days and about $1.17 per label-day. NOW DGL with Aloe Vera is listed at $15.96 for 100 veg capsules at Walmart. Nature's Way's GutGard ingredient partly justifies the premium, so this is not scored as extreme overpricing. Awarding -5 as a partial poor-value adjustment for one sampled product segment. 8, 34, 35 Current 2026 retail pricing. Full weight. · full weight |
| −3 | Garlic supplement value is slightly above some comparables but not out of range. Garlinase 5000 is listed at $15.99 for 30 tablets on Nature's Way and $25.68 for 100 tablets on iHerb, while NOW Garlic 5,000 is listed at $18.88 for 90 tablets at Walmart. Because the 100-count Garlinase price is close to market and both products disclose 5,000 mcg allicin or allicin potential, applying only a small -3 value penalty for brand-price variance. 14, 36, 37 Current 2026 retail pricing.

| +8 | High product-level retail ratings for Pearls. Walgreens lists Enzymatic Therapy Acidophilus Pearls at 4.7 stars with 146 reviews, and Walmart lists a Nature's Way Enzymatic Therapy Pearls Acidophilus multipack at 4.7 stars with 156 ratings. Awarding +8 within the +8 to +12 Amazon or retail rating range because reviews are strong, but the count is moderate rather than massive for the specific Enzymatic Therapy listing. 30, 31 Current or recent retail review pages. Full weight. · full weight |
| +6 | Additional positive product sentiment appears across broader Nature's Way Pearls channels. iHerb's Pearls Complete review page summarizes customer appreciation for convenience, small size, no refrigeration, and digestive improvements, while CVS review snippets similarly emphasize small size and digestive comfort. Awarding +6 because the pattern supports product satisfaction, but these are retailer summaries and may include successor Nature's Way branding rather than purely legacy Enzymatic Therapy packaging. 50, 51 Retail review pages crawled in 2026. Full weight. · full weight |
| +4 | Professional and practitioner-channel availability supports moderate practitioner adoption. Fullscript and Emerson Ecologics list Cell Forte MAX3, and Integrative Therapeutics is a related practitioner-oriented Schwabe or Nature's Way platform.

| −3 | Trustpilot and BBB signals are mixed or limited, so a small negative is appropriate. Trustpilot has a Nature's Way profile with 1,095 reviews and at least some negative visible review text in search snippets, while BBB lists Nature's Way Products as not BBB accredited. No strong unresolved complaint pattern was confirmed from the visible data, so applying only -3 rather than a poor-rating penalty. 53, 54 Current review profiles reviewed in 2026.
