Nature's Plus supplements

Jun 30, 2026 · 39 sources

A long-established natural-products brand with strong specialty formulas, average-to-good manufacturing evidence, and less information about each batch.

Trust score 66 out of 100 · Mixed

What it does well

  • Formulation: sampled specialty products use meaningful doses, branded ingredients and bioavailability technologies.
  • Social sentiment: legacy product families such as Animal Parade and SPIRU-TEIN show retail traction and long-term user loyalty.
  • Transparency basics: company identity, address, pricing, serving counts and policies are visible.
  • Quality: NSF GMP-related verification and in-house cGMP testing disclosures are stronger than many commodity brands.

Where it falls short

  • No public batch-level COA portal was found.
  • The 2022 gluten recall prevents a clean safety record.
  • Recent Proposition 65 notices create unresolved lead-warning transparency questions.
  • Flagship products such as Source of Life GOLD and SPIRU-TEIN can be expensive versus sampled comparables.

On record: NSF certified, third-party tested, premium ingredients and transparent pricing. Flagged: a recent safety issue.

Score by area

Quality 54 out of 100 · Poor

Implied quality score from adjustments: 54 out of 100. NaturesPlus has above-average manufacturing signals for a legacy supplement brand because NSF GMP-related verification and in-house cGMP testing are disclosed. The score is held down by a completed 2022 gluten recall, two recent allegation-based Proposition 65 notices and the absence of public batch-level COAs. Confidence is high for the recall and NSF existence, but lower for exact testing scope because methods and COAs were not public.

Not scored: No public COA portal, no complete batch testing archive, no ISO 17025 lab scope and no full FDA inspection reports were found in the accessible review. I also could not verify every accreditation claimed on the brand page against an independent directory.

How this score was built

Starts at 50, ends at 54.

  • +11 NSF GMP registration and claimed facility accreditation. Official NSF listings show Natural Organics, Inc. at 548 Broadhollow Road, Melville, NY under the dietary supplement GMP program and list a Natural Organics distribution facility in Reno. The brand's own accreditation page also claims NSF GMP certification for manufacturing and packaging and distribution. Awarding the low to middle of the +10 to +15 range because NSF verification is meaningful, but the official search excerpt available in this review clearly confirms the company listing and distribution facility while the manufacturing-site detail is primarily from the brand page. 12 Current official NSF listing reviewed in 2026. Full weight. · full weight
  • +4 In-house cGMP manufacturing and testing disclosed. NaturesPlus says products are produced in its own cGMP-compliant facilities and that it conducts in-house testing for quality, purity and potency. Awarding +4 within the +3 to +6 in-house lab and testing disclosure range because methods, lab accreditation status and batch reports are not published. 3 Current brand disclosure reviewed in 2026. Full weight. · full weight
  • −8 Isolated allergen contamination recall. FDA posted Natural Organics' voluntary May 6, 2022 recall of four lots of NaturesPlus Keto Living Sugar Control because routine testing found gluten in a raw material. Pattern calculation: one product and four lots out of a broad 400+ product catalog is isolated, so I used roughly 50% of a low-end -20 contamination penalty, then applied 75% temporal weight for a 2-5 year old event, yielding about -8. 516 May 2022 recall, about 4 years old. 75% temporal weight. · 75% weight
  • −3 Recent alleged lead warning issues in two California Proposition 65 notices. Two notices, one in October 2024 for Nature's Plus Revitalizing Green Food and one in February 2025 for NaturesPlus Collagen Creamer, allege lead exposure warning violations. This is not scored as proven contamination because these are notices, not a final judgment and no measured lab values were available in the reviewed notices. Low penalty applied because the issue appears limited to 2 products and is allegation-based. 67 2024 and 2025 notices. Full temporal weight, reduced for allegation status and limited scope. · full weight

Formulation 75 out of 100 · Adequate

Implied formulation score from adjustments: 75 out of 100. The sampled line shows several meaningful positives, especially branded ingredients, clear per-serving actives and better forms in the PRO, HEMA-PLEX and KalmAssure products. The main limitation is that NaturesPlus appears more label-backed than finished-product clinical-trial-backed, and complex whole-food formulas are hard to evaluate from public pages alone.

Not scored: This was a sampled product review, not a full audit of the 400+ listed catalog. Full Supplement Facts images, inactive ingredient counts and independent potency assays were not available for every product reviewed.

How this score was built

Starts at 50, ends at 75.

  • +10 Effective-dose pattern in sampled products. I sampled 10 commonly visible or strategically important products: Source of Life GOLD, SPIRU-TEIN, HEMA-PLEX, PRO Berberine 1500, PRO Suntheanine 200, PRO NAC 1200, PRO Curcumin Longvida, KalmAssure Magtein, PRO Super K and PRO ThymoQuin. Eight of 10 sampled products disclosed a meaningful per-serving dose or a recognizable branded active at a plausible supplemental dose. Pattern calculation: 8 of 10 sampled products equals 80%, which supports the lower end of the +10 to +15 majority-effective-dose range. I used +10 rather than +15 because this was label-based, not a full clinical benchmark audit. 17181920212223242526 Current product pages reviewed in 2026. Full weight. · full weight
  • +7 Branded premium ingredients across sampled specialty products. Sampled pages showed Suntheanine, Longvida SLCP curcumin, Magtein magnesium L-threonate, K2Vital, ThymoQuin and Ferrochel iron. This supports +7 within the +5 to +8 branded premium ingredient range because the practice is clearly present across specialty lines, although not proven across the entire catalog. 212324252627 Current product pages reviewed in 2026. Full weight. · full weight
  • +8 Bioavailability and delivery technologies. Sampled products include patented SLCP curcumin technology, magnesium L-threonate, chelated or Ferrochel iron and slow-release iron tablets. Awarding +8 at the low end of the +8 to +12 bioavailability technology range because the technologies are real, but not universal across the whole catalog. 23242719 Current product pages reviewed in 2026. Full weight. · full weight
  • +4 Key actives are often disclosed per serving in sampled specialty products. Berberine, Suntheanine, NAC, Longvida curcumin, magnesium and iron pages all disclose clear headline amounts or per-serving doses. Awarding +4 as partial credit toward no-proprietary-blend or clear disclosure because the review was sampled and some complex whole-food formulas remain harder to interpret. 192021222324 Current product pages reviewed in 2026. Full weight. · full weight
  • −4 Complex whole-food and shake formulas make some benefit claims difficult to evaluate. Source of Life GOLD promotes over 120 organic fruits and vegetables, and SPIRU-TEIN provides 14 g protein plus vitamins and minerals. These may be useful formulas, but the multi-ingredient nature makes many botanical or whole-food components hard to clinically benchmark. Applying a low -4 within the claims-without-product-specific-evidence range because the review did not find brand-owned clinical trials for these finished products. 171815 Current product pages and search review in 2026. Full weight. · full weight

Transparency 64 out of 100 · Mixed

Implied transparency score from adjustments: 64 out of 100. NaturesPlus is transparent about its company identity, address, product counts, serving sizes and many certifications. It is less transparent on batch-level testing, public COAs, full supply chain and the exact independent lab methods behind quality claims. The recent dismissed dose-label case and Proposition 65 notices create disclosure concerns, but neither was treated as proof of fraud or unsafe products.

Not scored: No direct customer-service COA request was performed. Full ownership documents, supplier lists, country-of-origin disclosures, complete lot-level COAs and all certification certificates were not publicly available in the reviewed sources.

How this score was built

Starts at 50, ends at 64.

  • +8 Ownership and corporate identity are disclosed. The website footer identifies Natural Organics Inc., the contact page lists the Melville address and phone number, and third-party company profiles connect NaturesPlus to Natural Organics, Inc. Awarding +8 at the low end of the +8 to +12 ownership disclosure range because private-company ownership depth, beneficial ownership and financing are not fully explained. 436 Current pages reviewed in 2026. Full weight. · full weight
  • +6 Manufacturing and distribution locations are disclosed. NaturesPlus lists 548 Broadhollow Road in Melville, New York, while NSF listings identify Natural Organics and a Reno distribution facility. Awarding +6 within the manufacturing-locations-disclosed range because public location detail is useful, but full supplier and contract-manufacturing mapping is not provided. 24 Current pages reviewed in 2026. Full weight. · full weight
  • +6 Facility certifications are shared publicly. The accreditation page lists FDA registration, New York State Board of Pharmacy registration, NSF GMP, organic and Health Canada site license claims, and the NSF directory provides independent support for Natural Organics' NSF GMP listing. Awarding +6 because certifications are visible, but not all claims were independently verified during this review. 12 Current pages reviewed in 2026. Full weight. · full weight
  • +3 Basic product-page transparency is good for sampled products. Product pages generally disclose count, servings, price, suggested use and headline active amounts for the sampled specialty products. Awarding +3 within the clear-labeling range because full downloadable labels or batch results were not consistently visible in the search excerpts. 1720212223 Current product pages reviewed in 2026. Full weight. · full weight
  • +4 Clear shipping and return policy. NaturesPlus discloses $5.95 standard shipping, free shipping over $50, expected 2 to 4 business day shipping and a 30-day satisfaction return policy for opened or unopened products. Awarding +4 for transparent pricing and policy terms. 28 Current policy reviewed in 2026. Full weight. · full weight
  • −6 Dose-labeling litigation raised a recent transparency concern, but it was not proven in a verdict. A class action filed in October 2024 alleged that 20 products misrepresented dosage by making consumers think the advertised amount applied to each pill rather than the serving. PacerMonitor reports the case was closed April 22, 2025 pursuant to a stipulation to dismiss. Applying -6, which is below the normal misleading-label range because the case closed without a merits finding in the accessible record. 101112 Filed 2024 and closed 2025. Full temporal weight, reduced for dismissal by stipulation and allegation status. · full weight
  • −4 Limited supply-chain transparency across the broad catalog. The brand gives some ingredient-specific traceability claims, such as farm-to-shelf traceability for ThymoQuin, but full country-of-origin, supplier and batch-sourcing disclosures were not found across the catalog. Applying -4, below the -6 to -10 premium-brand sourcing penalty, because broad sourcing disclosure is uncommon and some selective sourcing detail exists. 1626 Current product pages reviewed in 2026. Full weight. · full weight
  • −3 Recent Proposition 65 warning notices indicate possible warning transparency gaps. Notices from 2024 and 2025 allege lead warning violations for two products. Applying -3 because these are notices, not a judgment, and appear limited to two products in the reviewed record. 67 2024 and 2025 notices. Full temporal weight, reduced for allegation status and limited product scope. · full weight

Safety 77 out of 100 · Adequate

Implied safety score from adjustments: 77 out of 100. NaturesPlus does not show the type of recent FDA warning-letter pattern that would put it in the highest-risk tier, but its safety record is not clean. The main safety deductions are the completed 2022 gluten recall, two recent allegation-based Proposition 65 lead notices and a very old FTC advertising consent order. The recall was handled with no reported illnesses in the FDA notice, which materially limits the severity.

Not scored: Full FDA inspection reports, adverse event databases and complete legal docket documents were not reviewed. Proposition 65 notices did not provide lab values in the accessible excerpts, so contaminant severity could not be independently quantified.

How this score was built

Starts at 90, ends at 77.

  • +3 FDA and secondary inspection context does not show an official-action pattern in the accessible record. NaturesPlus claims successful FDA GMP inspection history, and secondary RegDataLab records show one Natural Organics inspection classified NAI and another VAI. Awarding +3 for clean-to-moderate accessible inspection context, not the full +6 clean-record credit, because the review also found a 2022 recall and recent Proposition 65 notices. 1373839 Current review in 2026, with inspection records from available secondary databases. Full weight for current context. · full weight
  • −9 Voluntary recall for undeclared gluten. FDA posted a May 6, 2022 company announcement for a nationwide voluntary recall of four lots of NaturesPlus Keto Living Sugar Control because the product was found to contain gluten. FDA noted possible serious or life-threatening allergic reactions for wheat or gluten-allergic consumers, but also stated no illnesses or adverse reactions had been reported and no other Natural Organics products were affected. Scoring: low-end serious voluntary recall penalty of -12, multiplied by 75% for 2-5 year recency, equals -9. 5 May 2022 recall, about 4 years old. 75% temporal weight. · 75% weight
  • −3 Recent Proposition 65 lead-warning notices. Two California notices in 2024 and 2025 allege lead warning violations for specific NaturesPlus products. Safety exception applied because potential contaminant warning issues score even if isolated, but the penalty is limited to -3 because notices are allegation-based, not a final judgment, and no lab values were reviewed. 67 2024 and 2025 notices. Full temporal weight, reduced for allegation status and limited scope. · full weight
  • −4 Historical FTC advertising order. In 2000, the FTC charged Natural Organics and Gerald Kessler with unsubstantiated ADHD treatment claims for Pedi-Active A.D.D.; in 2001, the matter was resolved by consent order. The FTC decision states the agreement was for settlement purposes only and did not constitute an admission that the law was violated, except jurisdictional facts. Scoring: base -16 for a regulatory advertising action involving disease-related child claims, multiplied by 25% because it is more than 10 years old, equals -4. 89 2000 complaint and 2001 decision, more than 20 years old. 25% temporal weight. · 25% weight

Value 51 out of 100 · Poor

Implied value score from adjustments: 51 out of 100. NaturesPlus is a mixed-value brand: several PRO products look fairly priced, and shipping and returns are clear, but flagship multivitamin and protein-shake products can be expensive versus credible comparables. The premium is partly justified by NSF GMP-related facility verification and branded ingredients, but public COAs or product-level USP or NSF Certified for Sport marks would make the value case stronger.

Not scored: Pricing was sampled from current official pages and a few competitor pages, not every retailer or every SKU. Discounts, subscriptions, retailer promotions and bundle pricing may materially change the final cost per serving.

How this score was built

Starts at 50, ends at 51.

  • +6 Transparent shipping and return terms. NaturesPlus discloses $5.95 standard shipping, free shipping over $50, 2 to 4 business day delivery after order processing and a 30-day return policy that applies to opened or unopened products. Awarding +6 within the transparent pricing range because terms are clear and shopper-friendly. 28 Current policy reviewed in 2026. Full weight. · full weight
  • +5 Some specialty products are fairly priced relative to their dose. PRO Berberine 1500 is $34.95 for 30 servings, PRO NAC 1200 is $12.95 for 30 servings and PRO Suntheanine 200 is $22.95 for 30 servings. Awarding +5 because these sampled products have competitive internal cost per serving, though this does not apply to the whole catalog. 202122 Current product pages reviewed in 2026. Full weight. · full weight
  • +8 Premium partially justified by quality signals and ingredient forms. NSF GMP-related verification, branded ingredients such as Longvida, Suntheanine, Magtein, K2Vital, ThymoQuin and Ferrochel, and specialty delivery technologies support some premium pricing. Awarding +8 within the premium-justified range, but not higher because public COAs and product-level NSF Certified for Sport or USP Verified marks were not found. 12212324252627 Current pages reviewed in 2026. Full weight. · full weight
  • −12 Source of Life GOLD tablets are materially above sampled multivitamin comparables. NaturesPlus Source of Life GOLD tablets are $114.95 for 60 servings, about $1.92 per serving. Thorne Basic Nutrients 2/Day is $40 for 30 servings, about $1.33 per serving, and Garden of Life Vitamin Code Men is $39.19 for 120 capsules, commonly a 30-serving format, about $1.31 per serving. Pattern calculation: NaturesPlus is roughly 44% to 46% above these sampled comparables, so I applied -12 at the low end of the -12 to -18 overpriced range because the formula is more complex and whole-food-positioned. 172930 Current product pages reviewed in 2026. Full weight. · full weight
  • −6 SPIRU-TEIN protein economics are weak if judged as a protein powder. The sampled SPIRU-TEIN page lists $21.00 for a 16-serving product with 14 g protein, about $1.31 per serving and about $0.094 per gram protein. NOW Sports Pea Protein is $29.99 for 27 servings with 24 g protein, about $1.11 per serving and about $0.046 per gram protein. I applied -6 rather than a larger penalty because SPIRU-TEIN also includes vitamins and minerals and is positioned as a meal shake, not a pure protein isolate. 1831 Current product pages reviewed in 2026. Full weight. · full weight

Sentiment 74 out of 100 · Adequate

Implied social sentiment score from adjustments: 74 out of 100. NaturesPlus has positive legacy and retail sentiment, especially around Animal Parade and SPIRU-TEIN, with some evidence of long-term loyalty. The brand does not show the high-volume practitioner or Reddit enthusiasm seen with top-tier professional brands, and the small Trustpilot profile is weak. Overall sentiment is favorable but not elite.

Not scored: Social evidence was uneven. Amazon review aggregates, Reddit discussions, BBB complaint details and full Trustpilot review contents were not comprehensively accessible in this review.

How this score was built

Starts at 60, ends at 74.

  • +8 Strong retail traction and product recognition for children's products. Amazon's Animal Parade listing states the product won the 2026 VITY award for best-selling children's health supplement, and Amazon search results show high recent purchase activity for Animal Parade and Source of Life products. Awarding +8 because this is strong retail traction, but not the full Amazon-rating range because verified review averages were not consistently accessible in the reviewed pages. 3516 Current retail pages reviewed in 2026. Full weight. · full weight
  • +4 Small but positive local review footprint. Chamber of Commerce shows Natural Organics Inc., NaturesPlus at 4.1 stars from 16 reviews, including a long-term SPIRU-TEIN user review. Awarding +4 because review volume is low but sentiment is mostly positive. 34 Review page current in 2026, with visible review dates from 2022 to 2023. 75% weight applied for older visible review dates. · 75% weight
  • +5 Legacy niche loyalty around SPIRU-TEIN and Animal Parade. The brand has long-running specialty lines, and the product catalog and retail pages show sustained demand. Awarding +5 as partial community-endorsement credit because evidence supports loyal niche use, but not broad Reddit or practitioner-darling status. 16183435 Current product and retail pages reviewed in 2026. Full weight. · full weight
  • −3 Trustpilot signal is weak and negative, but very low volume. Trustpilot shows a 2.8 average from only 3 reviews for the UK site and explicitly notes the company has not invited customers, so reviews may not be representative. Pattern calculation: the normal low-Trustpilot penalty is -12 to -18, but 3 reviews is a tiny sample, so I applied roughly 25% of a -12 penalty, rounded to -3. 32 Current Trustpilot page reviewed in 2026. Full temporal weight, heavily reduced for sample size. · full weight

Best for

  • Shoppers who want a legacy natural-products brand with NSF GMP-related facility verification and broad availability in family, multivitamin and health-food retail categories.1216
  • Users looking for focused specialty formulas with branded ingredients, such as Suntheanine, Longvida, Magtein, K2Vital, ThymoQuin or Ferrochel, rather than anonymous commodity blends.212324252627
  • Parents or long-time natural-products shoppers who specifically like Animal Parade, SPIRU-TEIN, HEMA-PLEX or Source of Life and are comfortable paying a premium for those product families.16181935

Skip if

  • You require public, batch-specific COAs before buying. I did not find a public lot-level COA portal or downloadable batch reports in the reviewed official pages.1316
  • You need NSF Certified for Sport or USP Verified product-level assurance. This review found NSF GMP-related facility evidence, but not visible NaturesPlus product-level NSF Certified for Sport or USP Verified listings.21415
  • You are highly gluten-sensitive or allergen-risk-averse and want a brand with no recent allergen recalls. FDA posted a 2022 voluntary recall for four lots of Keto Living Sugar Control due to undeclared gluten, although the notice said no illnesses had been reported.5

Common questions

Is NaturesPlus a good supplement brand?

NaturesPlus looks like a generally credible legacy supplement brand, especially for shoppers who value NSF GMP-related facility verification, branded ingredients and long-running product families. It is not a top-transparency brand because I did not find public batch COAs, and its record includes a 2022 gluten recall plus recent allegation-based Proposition 65 notices.12567

Is NaturesPlus third party tested?

NaturesPlus has third-party facility-level verification signals, including NSF GMP-related listing evidence for Natural Organics, and ConsumerLab lists one NaturesPlus product in its review database. I did not find a public batch COA portal or broad product-level third-party test reports, so the evidence supports facility verification more clearly than product-by-product public testing.2313

Does NaturesPlus have any recalls?

Yes. FDA posted a May 6, 2022 voluntary recall for four lots of NaturesPlus Keto Living Sugar Control because the product was found to contain gluten; the FDA notice said no illnesses or adverse reactions had been reported and no other Natural Organics products were affected.5

What is the #1 most trustworthy vitamin company?

There is no official single #1 most trustworthy vitamin company. For trust, shoppers should prioritize product-level marks and public verification, such as USP Verified, NSF Certified for Sport when relevant and transparent COAs; NaturesPlus has NSF GMP-related facility evidence, but I did not find visible USP Verified or NSF Certified for Sport product listings for the brand in this review.21415

Is NaturesPlus a trusted brand?

NaturesPlus is reasonably trusted in the natural-products market, with a long operating history, visible facility-quality claims and loyal product families like Animal Parade and SPIRU-TEIN. It falls short of the highest trust tier because batch COAs were not public, recent Proposition 65 notices remain unresolved in this review and the 2022 gluten recall prevents a clean safety badge.1567161835
