Labdoor Review: Are Their Rankings Accurate?

Labdoor Review: Are Their Rankings Accurate?


| |
| |

Labdoor is a brand that publishes rankings of dietary supplements and food products. The brand claims that their website can help users "Shop Smart" and determine "what's really in your supplements."

But are Labdoor's test results and rankings accurate? What is Labdoor actually testing? Are their tests up-to-date? And how does Labdoor compare to other supplement testing sites like ConsumerLab?

In this article we'll answer all of these questions and more, as we analyze Labdoor's methodology, share our concerns about their scoring process, and compare Labdoor to ConsumerLab to give our take on which platform is a better option for supplement test results.

We'll also review Labdoor's certification program, and explain why the brand's failure to publish testing dates for many of their test results is a problem.

Confusing Scoring Process

Labdoor's scoring system has five categories: Label Accuracy, Product Purity, Nutritional Value, Ingredient Safety, and Projected Efficacy.

The brand's methodology for this scoring system, while described on their website, is not transparent in terms of weighting.

As an example, a ginseng supplement called Auragin received a Labdoor score of 61.3 out of 100.

There is no "Projected Efficacy" or "Ingredient Safety" or "Nutritional Value" listed on the test results page. 

The only data showing on the results page for this supplement is the ginsenoside level (which would be categorized under "Label Accuracy"), and the pesticide and heavy metals level (which would be categorized under "Product Purity").

As a reader, you're left entirely unclear how the brand reached the 61.3/100 rating, and why the three sections listed above, which are supposed to be a part of Labdoor's "Scoring Process," are not included.

Questionable Testing Methodology

There are several elements of Labdoor's testing methodology that are confusing to us.

First, the brand does not appear to publish the raw data of the test results anywhere on their website.

If Labdoor has this information, why not publish it? 

Our main issue is that Labdoor's scoring methodology makes no sense at all to us in the context of label accuracy. 

Consider the score below for a supplement called Nature Made Super B Energy Complex:

Labdoor Nature Made Super B Energy Complex score

With such a high score, a reader would probably assume this supplement is at the very least accurately labeled. However, that's not the case at all, according to Labdoor's own test results.

Labdoor's tests show that this supplement contains barely over 50% of the stated dose of folic acid and panthenoic acid, and over 300% of the vitamin B12 dose, as shown below:

The Labdoor test results and score for a magnesium brand called Natural Calm, from when we last updated this article, are shown below:

Labdoor Natural Calm test results

How did this supplement get a score of 87.1 when the magnesium content was found to be 263% higher than the brand claims?

This a consumer safety issue. Magnesium regulates electrical conduction in the heart and helps regulate blood pressure, and as documented in a 2022 medical review, excess magnesium can cause "serious health issues."

Labdoor has removed this test result and brand from their website after we called out this information in our article.

We are not suggesting that the dose of magnesium found in this supplement is high enough to cause health issues.

We're simply providing evidence to support why we think Labdoor's rating method isn't helpful at all for consumers.

Failure to Publish Testing Dates

At the time of updating this article, Labdoor appears to have removed all of the testing dates from brands that haven't participated in Labdoor's certification program. 

This makes all of the data useless in our opinion.

Without updated testing dates, consumers have no way to know if they're looking at test results from a batch that was produced five years ago.

Product test results are only useful if the consumer can ensure that they're test results of the same batch of product the company is currently selling.

Supplement companies regularly manufacture new product batches, and each batch is subject to unique risks and quality control changes.

A supplement company may sell one batch of a supplement with lead levels three times higher than the previous batch of the same supplement, due to increased contamination of the raw materials.

We recommend that consumers disregard any food or supplement test data that is not dated with a lot number.

Who's Behind Labdoor?

Labdoor’s About Us page doesn’t mention a single member of the company. 

In our opinion, this is somewhat of a red flag because testing dietary supplements for label accuracy and contaminants is a technically complex process that requires highly specific knowledge and education.

We prefer to use health and medical services run by brands with a transparently-published team of credentialed medical experts, as this seems to reduce the risk of methodological errors (such as some of the ones cited in the previous sections of this article).

A California Secretary of State Corporations search reveals that the President of Labdoor is named Neil Thanedar.

His website describes how he holds a Bachelor's Degree in cellular and molecular biology, and how he co-founded a product development and testing laboratory that was later acquired. 

It's a good thing that Labdoor's founder has some relevant educational and entrepreneurial experience, but we hope that there are people on the Labdoor team with more advanced degrees like PhD and MD, and if Labdoor has such experts they should publish this information (like we do), so that users can know that the people creating the rankings are qualified to do so.

Is Labdoor's Certification Program Legit?

Labdoor certified product example

Labdoor has a certification program that allows supplement brands to opt-in to product testing.

The data quality and transparency is vastly higher for Labdoor's certified products than for products not certified with Labdoor.

For certified brands, Labdoor publishes the full test results, including lot number and testing dates. We believe this is useful information for consumers.

Our guess is that testing of non-certified supplements is too expensive for Labdoor to regularly maintain, but because brands pay Labdoor for certification, a higher level of data quality and transparency is attainable for certified products.

The testing methodologies for the purity and label accuracy analyses are not published on the test results page for Labdoor's certified supplements, which is underwhelming, but we still think this aspect of Labdoor's business is a net positive for consumers.

Labdoor vs. ConsumerLab

ConsumerLab is another supplement testing site, so consumers are often curious about which is a better option.

We would recommend ConsumerLab over Labdoor for several reasons:

1) ConsumerLab is run by publicly-listed scientists

The brand has a Team page with multiple PhDs and doctors running their operations.

2) ConsumerLab publishes testing methodology

3) We have never noted scientific discrepancies or questionable practices related to testing on the ConsumerLab website.

We believe that ConsumerLab's product testing data is higher quality and more useful to consumers than Labdoor.

That being said, ConsumerLab does charge a fee (currently $99.95 for two years of access).

For consumers on a budget, Labdoor's certification program is worth checking, as it's a free resource and we believe the data quality of Labdoor's certification program and ConsumerLab's regular product testing is comparable.

Labdoor Pros and Cons

Here are the pros and cons of Labdoor in our opinion:

Pros:

  • Free to access
  • Certification Program data is useful to consumers
  • Wide range of supplements tested
  • Founder has relevant experience

Cons:

  • Highly questionable scoring methodology 
  • Supplements can score well with large nutrient excesses
  • Supplements can score well with large nutrient deficiencies
  • No testing dates or lot numbers on non-certified products
  • Scores for non-certified products have no value in our opinion
  • Unclear if MDs and PhDs on their team

Conclusion

We do not currently consider Labdoor to be a particularly valuable resource for consumers.

The brand has a confusing scoring process, questionable testing methodology and there is no indication whether or not scientists or medically credentialed experts are completing the brand's testing and reporting.

Test results on Labdoor which are not part of Labdoor's certification program do not even include a testing date or lot number, making the results useless in our opinion, because they could be from a years-old batch.

Labdoor's certification program does provide useful information to consumers at no cost, so we believe this is a resource that's worth checking.

We hope that in the future, Labdoor publishes the testing methodology used for their certification program.

We would recommend ConsumerLab (which is another supplement testing company) over Labdoor, because we believe the quality and breadth of data is superior.
