The Bad Supplements List


The Bad Supplements List

Bad U.S. Supplements List American Gothic

Bad Supplements: A Working List of Mislabeled Products

Healthy food was simpler in 1930, when Grant Wood painted American Gothic. At the time, healthy food came from down the road. Later, health food stores appeared with capsules made by reputable U.S. companies, with traceable ownership and offices or stores you could visit. Then came internet merchants, which at least in the beginning were sure to identify their owners and locations. 

Things have changed. Today, for a large percentage of U.S. supplement consumers, product transparency and traceability has all but disappeared. Anonymous supplement sellers, often single individuals shielded by third-party platforms, are operating from unidentified locations both here and overseas. Their products are often made by unidentified manufacturers in unknown locations, using ingredients of unknown quality and sourcing.

The main reasons for the inclusion may include obvious errors or misrepresentations in product labeling or marketing, or clear public evidence (such as test results) of mislabeling.

The Bad Supplements List

August 24, 2023


We performed a preliminary investigation into the identity of the 14 brands failing Now Foods astaxanthin potency testing… so here’s a quick and dirty breakdown of the cheaters. 

1. About half of the brands are not associated with a physical address 😬

And out of the ones I could find a physical address for, only one address has a building large enough to produce supplements. According to Google Maps, most brands that had a physical address were located inside an unrelated business, or a residence like an apartment or house. 

2. About half of the brands have no website 😥 

Those without websites only have an Amazon Seller and/or Walmart seller page with no contact information.

3. Thirteen of fourteen brands don’t list the name of an owner or person responsible 😩 

(Don’t you hate when the “About Us” page says nothing about who’s behind the brand, and the “Contact Us” page has no address or phone number? Too bad, because that’s the new normal.) 

4. ZERO Amazon-only Seller pages listed a person’s name, business address or phone number 🙄 

2023 NOW Foods astaxanthin testing supplements

As reported in Nutraceuticals World in August 2023, 13 of 22 supplement brands tested by NOW Foods from Amazon Sellers contain less than 10% of the labeled amount of astaxanthin. 

Astaxanthin is generally an expensive ingredient, and manufacturers are often interested to cut costs on testing or production when no one is looking.

aSquared: contains 0.6 mg versus 10 mg labeled

NOW Re-Testing for CoQ10

2022 Results found at NOW Foods website

NOW continued its award-winning industry self-policing program of testing unfamiliar brands found on Amazon and, unfortunately, the cheating continues. The program, begun in 2017, tests high value products sold by unheard of brands on Amazon at both internal and external labs, and evaluates the results compared to label claims.

NOW reexamined eight brands of CoQ10 to see if those that were identified as low potency in testing done in 2020 had improved and found the same serious problems remain for seven out of eight brands tested.  Additionally, as shown below, NOW found brands cheating by misrepresenting potencies through deceptive labeling tricks.  

NOW purchased three samples of each product below and tested by HPLC both internally at NOW’s state-of-the-art labs and externally at the highly regarded Eurofins labs.  It is apparent by looking at lot numbers and bottle types that the same manufacturer is supplying multiple brands with the same fraudulent products (see Florida brands in the chart below).  

  • Clear Formulas, aSquared, Foxy Doc and Healthy Way brands all mislabel their product as “400mg/6%” potency.  This is deceptive when the front panel says “400mg” potency and the Amazon title says “CoQ10 400mg Max Strength”.  The customer gets less than 24mg CoQ10 per capsule.
  • NOW previously tested a variety of CoQ10 brands on Amazon in 2017, 2018 & 2020 with similar failing results. aSquared, Healthy Way, NasaBe’Ahava and We Like Vitamins were all under 35% potency in 2020 as well.
  • Seven out of eight brands tested had less than 30% of the potency claimed
  • Perhaps most alarming, three of the eight brands claimed to be in vegetarian capsules, but testing both at NOW and at Eurofins confirmed gelatin was used.  The failing brands are Clear Formulas, Healthy Way and Sundhed.
