Labdoor is a privately held medical company registered in San Francisco, California, founded in May 2012 by Neil Thanedar. It provides information on dietary supplements, which do not require testing by the FDA in the United States.[1]

Key Information

History

[edit]

Born and raised in St. Louis, Missouri, the son of Shri Thanedar, Neil Thanedar graduated from the University of Michigan in Ann Arbor, Michigan, with degrees in Cellular & Molecular Biology and Business Administration.[2][3]

Neil Thanedar co-founded Avomeen Analytical Services with his father in 2010.[4][5] He founded Labdoor (originally "Labrdr Inc"[6]) in May 2012[7][8] with co-founders Rafael Ferreira, Helton Souza, and Tercio Junker.[9][10][11] Labdoor pursued venture investors in 2012, 2015, and 2016, ultimately securing approximately $11 Million from groups including Y Combinator, Floodgate Fund, and Rock Health.[11][12][13] A controlling share of Avomeen Analytical Services was sold to an investment group in 2016.[14][15][16][17]

Products and services

[edit]

Since November 2013, Labdoor's primary income is affiliate marketing for retailers, such as Amazon, of products they have tested and certified.[18] Labdoor also offers testing services to supplement manufacturers, assessing "accuracy", "purity", and "sport".[19] If a product passes testing, Labdoor will also "drive sales" through its certification program and retailer referrals.[20][19]

As of September 2021, Labdoor's new product selection procedure uses market research and an internal "tally of votes" system to choose which new product category will be selected to test next.[21]

In June 2018, Labdoor launched the crypto-currency TEST. It seeks to create a incentive system for individuals or organizations to anonymously create or raise a bounty on a product for independent laboratories to test.[22][23] TEST will be in initial coin offering (ICO) stage through December 2018.[24]

Labdoor buys dietary supplements directly from retailers, sends the products to an FDA-registered laboratory for analysis,[citation needed] and publishes the findings. Its mission is to share information to help consumers make the right decisions for themselves about dietary supplements.[according to whom?] Labdoor's rankings have sometimes been published by the press and online media.[25][26][27][28][29]

[edit]

Their findings resulted in the FDA taking a closer look at the safety of energy drinks.[30] Labdoor evaluated Alex Jones's supplements, stating "the science behind many of their claimed ingredients are questionable."[31][32][33][34] Some 2015 tests of supplement products conducted by a third-party laboratory, which was organized by Labdoor and the Canadian Broadcasting Corporation (CBC), were first published and later retracted upon repeat testing.[35] The supplements were correctly labeled and there was no contamination nor deficiency in the products.[36]

As of August 2016, Labdoor allows manufacturers to challenge a report of a product by re-testing the product, or opt-out of having any reports of the manufacturer's products published on Labdoor's website.[37][38]

While its data-driven approach has been credited with exposing discrepancies in popular brands, Labdoor's scoring has drawn for permitting substantial nutrient excesses or shortfalls without severe penalties, potentially understating quality risks.

History

Founding and Early Years

Labdoor was founded in May 2012 in , , by Neil Thanedar as a consumer-facing platform to independently test and rank dietary supplements based on laboratory analysis of label accuracy, purity, and other quality metrics. The company, initially incorporated as Labrdr Inc., aimed to address consumer skepticism in the supplement industry by providing transparent, science-backed evaluations without reliance on manufacturer claims. Thanedar, then 24 years old, served as CEO, drawing on his prior experience co-founding Avomeen Analytical Services in 2010 with his father, an FDA-registered laboratory specializing in product safety testing that supplied the analytical infrastructure for Labdoor's early operations. In its initial phase, Labdoor focused exclusively on dietary supplements, purchasing products from retail sources and subjecting them to third-party chemical analysis to verify ingredient content and detect contaminants. By late 2012, the platform had begun publishing results for select categories, with the first approximately 100 products tested within nine months of launch, emphasizing metrics like projected and ingredient safety. This bootstrapped approach highlighted widespread discrepancies between label claims and actual contents, such as under-dosed active ingredients in popular multivitamins and protein powders, positioning Labdoor as an early watchdog in a market lacking regulatory oversight. Early growth was constrained by funding challenges, with the company testing around 300 products by mid-2014 while operating on limited capital, including a small seed investment from 's Winter 2015 cohort. Despite these hurdles, Labdoor expanded its database methodically, prioritizing high-demand categories like protein supplements and fish oils, and gained traction through free public access to rankings, fostering consumer trust amid revelations of industry adulteration rates exceeding 20% in some tested batches.

Growth and Milestones

Labdoor achieved a pivotal funding in October 2016 with a $3.4 million , led by investors including Aventura VC and Correlation Ventures, which enabled scaling of laboratory testing and platform enhancements after years of -stage . Subsequent capital raises supported operational continuity, culminating in a total of $8.21 million across five rounds by 2025, comprising three investments and two early-stage tranches, with the latest being a $0.15 million note in December 2022. Revenue demonstrated steady, albeit incremental, growth, increasing from $422,800 in 2021 to $421,100 in 2023 and $532,700 in 2024, alongside maintaining a lean team of 10 employees focused on expanding product testing volumes. In 2022, the company launched a crowdfunding campaign on Wefunder targeting consumer health product validation, valuing the business at $20 million and broadening access to non-institutional investors.

Recent Developments

In 2022, Labdoor launched a campaign on Wefunder, seeking investment at a $20 million valuation to support its operations in scientific reviews of consumer health products. As of 2025, Labdoor remains active in independent laboratory testing of supplements, with its services utilized by Health for verifying protein powder batches in a review published on October 1, 2025, where specific products were submitted for purity and potency analysis. The company continues to offer certifications such as (Purity + Accuracy), Sport, and THC Free, without reported changes to its core testing framework since its last venture funding round in November 2016. No major acquisitions, leadership shifts, or expansions have been announced in recent years, indicating steady operations focused on B2B verification services amid a competitive supplement testing market.

Testing Methodology

Laboratory Testing Processes

Labdoor's laboratory testing processes commence with the anonymous purchase of products from retail shelves and platforms to replicate access and maintain independence from manufacturers. Selected items, primarily top-selling vitamins, supplements, and related goods, undergo rigorous chemical analysis at third-party, FDA-registered . This step ensures that testing reflects real-world product availability without manufacturer influence or pre-submitted samples. The core of the process involves quantitative verification of label claims through high-performance liquid chromatography (HPLC) for active ingredients like vitamins and amino acids, which measures concentrations against stated amounts to assess accuracy—often revealing discrepancies where products contain 20-150% of claimed levels or include unlisted additives. Purity evaluations screen for contaminants using inductively coupled plasma mass spectrometry (ICP-MS) for heavy metals such as lead, arsenic, and mercury, with detection limits typically below regulatory thresholds like those set by the USP or FDA. Gas chromatography-mass spectrometry (GC-MS) and GC-flame ionization detection (GC-FID) detect volatile impurities, adulterants, or undeclared pharmaceuticals, while microbial testing checks for pathogens like E. coli or Salmonella via standard plating or PCR methods. Additional analyses evaluate nutritional completeness by quantifying macro- and micronutrients beyond labels, including proxies like dissolution rates in simulated gastric fluids. All tests adhere to (GLP) standards where applicable, with labs selected for accreditation and expertise in matrices to minimize false positives or analytical variability. Results from multiple batches may be averaged for consistency, though single-lot testing predominates for efficiency. These processes prioritize empirical detection over manufacturer self-reporting, addressing common industry issues like under-dosing or , as evidenced by Labdoor's findings of heavy metal exceedances in over 10% of tested proteins and multivitamins since .

Scoring and Ranking System

Labdoor's evaluates supplements across five primary criteria: label accuracy, product purity, , ingredient safety, and projected efficacy. These dimensions are assessed through independent testing of purchased retail products, yielding individual sub-scores that contribute to an overall quality score on a 100-point scale. The methodology employs proprietary algorithms to weight and aggregate these factors, assigning letter grades from A+ to F based on relative performance within tested categories. Label accuracy measures the alignment between a product's claimed levels and those detected via chemical analysis, such as (HPLC) or . For instance, protein supplements are tested for actual protein content against label declarations, with deviations penalizing the score; products exceeding 95% accuracy in key actives often receive higher marks. Product purity assesses contamination risks, including like lead, , , and mercury, as well as microbial impurities, using (ICP-MS). Thresholds are set conservatively, such as lead below 5 mcg per serving for certification eligibility. Nutritional value evaluates the formulation's completeness and balance relative to category standards, incorporating factors like bioavailability and synergistic nutrient profiles informed by clinical research data. Ingredient safety scrutinizes active ingredients for dosage-related risks (e.g., exceeding safe upper limits) and additives for potential adverse effects, drawing from toxicity databases and regulatory guidelines. Projected efficacy estimates potential health benefits based on peer-reviewed studies of ingredient dosages and combinations, prioritizing evidence from randomized controlled trials over anecdotal claims. The composite quality score integrates these sub-scores via weighted proprietary formulas, emphasizing empirical lab data over manufacturer inputs to prioritize transparency. Rankings are generated by sorting products within specific categories—such as multivitamins, protein powders, or —first by descending quality score for overall performance, and secondarily by value, which pairs quality against retail price to identify cost-effective options. Category rankings are updated periodically as new tests are conducted, with top performers highlighted in public lists; for example, as of 2020, supplements were ranked after analyzing 19 products for D3 content and contaminants. This system aims to guide consumers toward verified high-quality options amid industry variability, though proprietary weighting limits full replicability.

Quality Assurance Measures

Labdoor employs FDA-registered laboratories to conduct detailed chemical analyses of supplement samples, focusing on metrics such as content, purity from contaminants like and microbes, and label accuracy. Samples are acquired through anonymous purchases from retail sources, ensuring blind testing that replicates consumer conditions and minimizes opportunities for manufacturer interference or sample alteration. In its certification programs, Labdoor implements verification protocols involving multiple independent FDA-registered labs to confirm results. For instance, applicants may provide a from their own independent lab, after which Labdoor commissions a final test from a distinct FDA-registered facility not involved in prior analyses. Failed products can undergo retesting with new lots, with costs borne by the applicant, while a formal challenge process allows competitors to request reanalysis at their expense, using yet another unaffiliated lab; outcomes from these challenges are binding and update public rankings. These measures aim to cross-validate findings and address discrepancies, though FDA registration primarily denotes facility compliance rather than independent for analytical competence, such as ISO/IEC 17025 standards for testing laboratories. No public disclosures indicate routine use of internal quality controls like duplicate sample testing or in standard rankings.

Services and Products

Core Testing Categories

Labdoor evaluates products across dozens of nutritional supplement categories, prioritizing those with high consumer demand such as protein powders, multivitamins, (omega-3), supplements, and energy drinks. The company has tested and ranked items in 42 distinct categories, selected based on U.S. sales volume and popularity in and fitness markets. These include single-nutrient products like vitamins, , calcium, CoQ10, and monohydrate, as well as performance aids such as branched-chain (BCAAs), electrolytes, and extracts. In protein categories, Labdoor assesses , , and plant-based isolates for muscle-building claims, while testing covers broad-spectrum formulations aimed at daily nutritional gaps. and CBD oil categories focus on anti-inflammatory and wellness supplements, with additional scrutiny for contaminants like . and evaluations target content, stimulants, and endurance enhancers, reflecting consumer use in exercise routines. This category diversity allows Labdoor to address variability in supplement quality, where independent lab analyses reveal discrepancies in levels across brands.

Certification and Additional Offerings

Labdoor provides certification programs designed to verify the quality of dietary supplements through independent laboratory testing for label accuracy, purity, and compliance with specific standards. These certifications include Quality (Purity + Accuracy), which assesses product formulation against claimed ingredients and absence of contaminants; Sport, tailored for athletes to ensure freedom from World Anti-Doping Agency (WADA)-banned substances; and Quality (Purity + Accuracy) THC Free, confirming undetectable levels of THC alongside purity and accuracy metrics. To qualify, products must achieve scores exceeding defined thresholds in purity (e.g., no heavy metals or microbial contaminants above limits) and accuracy (e.g., active ingredients within 10% of label claims), with ongoing monitoring required for renewal. The core Quality Certification Program operates as a 12-month renewable subscription, enabling certified products to display Labdoor seals on packaging and materials while featuring prominently on Labdoor's website for consumer visibility. Launched in as part of expanded services for supplement brands, these programs emphasize consistent , with Labdoor conducting periodic re-testing to maintain status. Certifications are positioned as tools, with data indicating they enhance online sales through trust signals, though Labdoor maintains that testing remains independent of participating brands. Beyond standard certifications, Labdoor offers the Amazon Certification Program, introduced on February 3, 2021, to assist supplement manufacturers in complying with Amazon's requirements for Certificates of (CoAs), including targeted testing for contaminants and potency to facilitate platform listings and sales. Additional enterprise services include custom chemical testing for , allowing brands to address specific formulation challenges such as stability or novel ingredient validation, often integrated with pathways for comprehensive support. These offerings extend Labdoor's model from consumer-facing rankings to business-oriented tools, with all testing performed in accredited labs to uphold claims of rigor.

Business Model and Operations

Revenue Streams and Funding

Labdoor has secured funding totaling approximately $6.56 million across multiple rounds from investors such as , Correlation Ventures, Heroic Ventures, and others. Its earliest notable round included a $125,000 investment from in August 2015, followed by a $4.3 million round led by Correlation Ventures in July 2016. The company completed additional early-stage funding, including a contributing to its overall capital, with the most recent being a $150,000 convertible note on December 1, 2022. Labdoor has also pursued , launching a campaign on Wefunder in 2022 at a $20 million valuation to support expansion of its health product review platform. The company's primary revenue streams include commissions from consumer purchases of reviewed products via platform referrals, services offered to supplement manufacturers for verified quality seals, and direct sales through its where users can buy tested supplements. Initially reliant on as its core income source, Labdoor shifted emphasis toward programs by 2022, enabling brands to pay for independent validation while maintaining free access to basic product rankings for consumers. In , Labdoor reported annual revenue of $532,700 with a team of 10 employees, reflecting steady but modest growth over 13 years of operations. Despite these for-profit mechanisms, Labdoor's stated model prioritizes consumer funding through demand-driven access to reports, without direct payments from companies influencing test selections or outcomes.

Claims of Independence and Potential Conflicts

Labdoor asserts its independence by stating that it operates as an "independent company" conducting tests on supplements without influence from manufacturers, with initial from venture capitalists rather than supplement companies. The company emphasizes that its core testing and rankings are driven by consumer interests, with products selected for evaluation based on market popularity and sales data rather than brand requests or payments. Labdoor maintains that analyses are performed blindly, using randomized, anonymized samples to prevent bias, and results are published transparently regardless of outcomes. However, Labdoor's revenue model raises questions about potential conflicts of interest. Since November 2013, its primary income has derived from commissions on sales of tested and certified products through retailers like Amazon, which could incentivize favorable rankings for high-selling items to boost referrals. Additionally, since 2017, Labdoor has offered paid programs, such as the 12-month Quality Certification subscription, where brands submit samples for , pay fees for testing (including chemical and microbiological assessments), and gain eligibility to display Labdoor seals and profiles on the company's site if standards are met. These services allow companies to use certifications for , potentially creating financial incentives to accommodate brand-submitted samples over fully independent selections. Critics, including analyses from media bias evaluators, have rated Labdoor's factual reporting as mixed due to these revenue dependencies, arguing that affiliate earnings and fees might subtly influence testing priorities or interpretations, even if core methodologies claim . Consumer discussions on platforms like have similarly questioned whether redirecting users to purchasable products via affiliates compromises neutrality, though Labdoor counters that testing integrity remains separate from sales linkages. Labdoor has not disclosed specific figures on revenue proportions but maintains that consumer-funded elements, like a portion of direct sales retained for testing (approximately 10%), support ongoing independence. No formal regulatory findings of have been reported, but the model's evolution from VC-backed startup to service provider for brands underscores ongoing scrutiny over whether financial ties undermine uncompromised evaluation.

Impact and Reception

Achievements in Consumer Protection

Labdoor's independent laboratory testing has identified widespread discrepancies in dietary supplement labeling and purity, enabling consumers to avoid substandard products. For instance, analysis of 29 cambogia supplements revealed that 16 brands contained less than 70% of the claimed levels, highlighting risks of ineffective dosing. Similarly, testing of 80 protein supplements showed that the majority exceeded label claims for sodium content, potentially misleading users about nutritional profiles. These disclosures, derived from retail-purchased samples analyzed in accredited labs, underscore common manufacturing shortfalls in an industry with limited regulatory oversight. By publishing detailed rankings and scores—factoring in label accuracy, purity, and —for free, Labdoor equips with data-driven tools to select verified high performers, reducing exposure to contaminants, adulterants, or under-dosed formulations. As of , the platform had evaluated over 900 products across 32 categories, amassing a database that pressures manufacturers to prioritize verifiable quality to maintain market viability. This transparency has amplified , as evidenced by third-party references to Labdoor's findings in reports on issues like rancidity in omega-3 supplements, where elevated oxidation levels indicated mishandling. Labdoor's certification initiatives further advance protection by setting benchmarks for purity, accuracy, and absence of banned substances, with participating brands undergoing rigorous validation that includes challenge mechanisms for disputed results. Launched in , these programs have incentivized industry-wide refinements, as manufacturers seek endorsements to differentiate compliant products amid heightened scrutiny from Labdoor's public rankings. The Federal Trade Commission's 2018 closing letter on Labdoor's practices, following review of advertising and endorsement claims, affirmed no violations, bolstering the platform's role as a credible arbiter in safeguards.

Industry and Expert Praise

Labdoor's independent testing approach has garnered recognition from professionals and media outlets for enhancing consumer trust in supplement quality. A 2025 Forbes Health analysis of protein powders, informed by accredited experts, incorporated Labdoor's scoring system, which converts lab-derived metrics into A-to-F letter grades to simplify evaluations of label accuracy, purity, and . Medical experts evaluating supplements in a March 2025 New York Post review highlighted Labdoor's A ratings as evidence of high product standards, based on third-party chemical analysis for potency and contaminants. Within the supplement sector, brands such as Garden of Life, , and MuscleBlaze have obtained Labdoor certifications for purity, accuracy, and absence of banned substances, reflecting industry reliance on its protocols to validate claims and appeal to informed consumers.

Criticisms and Limitations

Labdoor's testing methodology, while focused on label accuracy, purity, and projected efficacy, has inherent limitations in scope. The company conducts chemical analyses on samples purchased from retail outlets, typically representing single batches, which may not account for variability across production runs or formulation changes over time. This approach does not incorporate bioavailability assessments, stability testing under varied storage conditions, or clinical trials to validate projected health outcomes, relying instead on literature-based estimates for efficacy scores. Critics have questioned the scoring algorithm's balance, noting that products with substantial excesses—sometimes exceeding safe upper limits—can still achieve high grades, potentially underemphasizing risks from overages, while precisely labeled products may receive lower scores due to subjective weights on other criteria like ingredient safety profiles. Manufacturer disputes have highlighted methodological flaws, such as in the case of Natural Calm magnesium, where Labdoor's analysis used a test portion over 2.5 times the recommended without proportional adjustment, leading to contested purity and value ratings. The platform has also faced challenges over the timeliness of updates; for example, protein supplement rankings analyzed 16 products but have drawn complaints for stagnation, with some data originating from tests conducted years prior and not refreshed amid industry-wide reformulations. Legal actions, including a 2015 lawsuit by BPI Sports against Labdoor under Florida's Deceptive and Unfair Practices Act, allege inaccuracies in rankings that harmed sales, underscoring tensions between testers and manufacturers dissatisfied with results. These issues reflect broader limitations in independent testing services, where resource constraints limit comprehensive, real-time coverage across thousands of supplement variants.

Disputes with Supplement Manufacturers

In October 2015, BPI Sports, LLC, a manufacturer, filed a against Labdoor, Inc., in the U.S. District Court for the Southern District of (Case No. 0:15-cv-62212), alleging under the , violations of Florida's Deceptive and Unfair Trade Practices Act (FDUTPA), and with business relationships. BPI contended that Labdoor's independent testing of its protein supplements yielded inaccurate low rankings due to flawed methodology, specifically ignoring peptide chemistry relevant to protein efficacy, undisclosed affiliation between Labdoor's testing lab and its CEO, and Labdoor's promotion of higher-ranked products akin to its own offerings, suggesting commercial bias. Labdoor moved to dismiss the , arguing the claims lacked specificity on and interference with identifiable customers. On February 25, 2016, Judge Beth Bloom granted the motion in part, dismissing the and counts for failure to state a claim—citing vague allegations of harm to the "community-at-large" rather than specific business relationships—and ruling that lost profits constituted not recoverable under FDUTPA. The court permitted BPI to amend its FDUTPA and counts. No public record indicates further amendments led to a or ; the case appears to have concluded without a merits ruling in BPI's favor, underscoring challenges for manufacturers seeking to challenge third-party testing rankings in absent concrete of or direct harm. This dispute exemplifies broader industry tensions, where supplement companies contest negative evaluations that impact sales, though Labdoor maintained its tests relied on standardized for label accuracy and purity. No other major lawsuits between Labdoor and manufacturers have been documented in federal or state courts as of 2025.

Engagement with Government Agencies

In 2018, the (FTC) investigated Labdoor's advertising claims for its testing and ranking services following a referral from the National Advertising Division (NAD) of BBB National Programs. The NAD had initiated a review into whether Labdoor could substantiate assertions about the superiority and reliability of its ratings, but Labdoor declined to participate, prompting the referral. On February 27, 2018, the FTC's Division of Advertising Practices closed the investigation without further action, determining no enforcement was warranted. No documented direct engagements between Labdoor and the U.S. (FDA) have been reported, such as collaborative testing, advisory input, or regulatory petitions. Labdoor conducts its product analyses at independent laboratories registered with the FDA, which adhere to (GMP) standards for , but this operational compliance does not involve agency-level interaction or oversight of Labdoor's methodologies. Labdoor's interactions with other government agencies, including state-level regulators or international bodies, remain unverified in , with the company's focus primarily on voluntary consumer-facing testing rather than formal regulatory advocacy or partnerships.
