How do you actually shop for third-party tested supplements without falling for a badge?

/u/Pretty-Chill talked some about what you should look for in a positive way. I will talk about what you should look out for as red flags. Let's take a brand that has been blowing up lately, because they got David Beckham to come on to shill it: IM-8. I will link one of their Instagram posts to set the tone.

This makes it seem like they are the most transparent, properly tested, and clinically studied supplement on the market, right? Let's go to their site to assess that stance.

Here is the homepage: https://im8health.com/

Clinically-proven and third party tested are the claims. Sounds nice! Let's start with the clinical claim first. They link this supposed study on that page.

https://clinicaltrials.gov/study/NCT06655597?term=NCT06655597&rank=1

So it was a real study that was filed and seemingly started recruiting. Sweet! Let's look at the results to test their claims from it!

Here is the results section: https://imgur.com/a/YS44E5d

So zero results were posted to the clinical trials site. I wonder why? Let's search for it published elsewhere. The name of the study is "Efficacy of a Dietary Supplement Powder Formula (Daily Ultimate Essentials) in an Adult Population." If you search for that name, you see it referenced a bunch of times by IM-8 and on paid articles by them. However, you do not find the paper anywhere. There are no results, and no evidence that it even finished. You see it referenced on another site, but it also shows no results and not concluded, even though it was supposed to end a year ago.

So what is going on? Why can we not read this study, see the results, or even have any evidence it concluded at all? Did the study conclude, but the data wasn't favorable, so they prevented its publication? Why are they making huge claims about the results without any way to verify those results. Sus for sure. Let's move onto their other claims of 3rd party lab testing.

They make it seem like they are going above and beyond with testing, right? An average consumer would think this is great! However, let's really get down into the details.

Here is their COA for their Daily Essentials: https://im8health.com/cdn/shop/files/Vitaquest_20251007_508-0816A.pdf?v=11070239253346524266

Vitamin C label claim 900mg. Specification 900mg. Test result 900mg. Wow, they perfectly formulated! It's exact! Impressive. Wait, vitamin K is 30mcg for all as well. They are so good, they can get down to a single microgram accuracy in fills?!? These guys must be the best formulators in the world. Who is this third party lab they are using? Vitaquest?

These guys are not a lab at all! This is their contract manufacturer! Those COAs are just supplier COAs, and those "test results" are just by-input numbers. Their manufacturer is saying they put 30mcg of vitamin K in there, so the COA says there is 30mcg of vitamin K in there. That's not a 3rd party lab test at all! What about their other product?

Here is the COA for their Daily Ultimate Longevity: https://im8health.com/cdn/shop/files/JW_202510_A241941025.pdf?v=11204485844546104477

Wait wait wait... FTIR identification of a complex mixture of a bunch of plants? That's not an appropriate methodology for ID! Anyone that knows anything about analytical chemistry could tell you that you cannot use FTIR to prove identity of complex plant matrices. That's what HPTLC is for. Then they say they HPLC for taurine content. Well taurine doesn't have a chromophore, so the UV detector can't see it in a sample. They would have to do precolumn derivatization to properly measure it with an HPLC-UV. This works well for pure taurine. However, in a complex matrix like their finished product, there are going to be matrix interferences. It's something that can be accounted for, but the lab has to be good. Let's look up this lab to see how good they are. JW Nutritional...

This is just another contract manufacturer!!! None of these are 3rd party lab tests. These are all supplier COAs from the manufacturer making their product! So all this talk about testing is horseshit. But what about NSF Certified For Sport? Let's look at that, shall we?

Here is the NSF Certified For Sport COA for their essentials: https://im8health.com/cdn/shop/files/J-00528294_TestReport.pdf?v=17203341094094650992

Scroll down that report and tell me what you see. Do you see any results in there for the content of the formulation, heavy metals, microbial contamination, or bioactive content? NOPE! NSF Certified For Sport only tests for banned substances, and they only do it once a year. People think this NSF Certified For Sport is testing to ensure the product meets label claims for every batch, but that is not what is happening. It's just a yearly banned substance screen. That's it.

So zero evidence of clinical trial results for their claims, no actual 3rd party lab testing being done, contract manufacturer COAs that use by-input claims instead of actual results on most ingredients, improper methodologies being used by the contract manufacturer in some cases when they do claim to test, but all wrapped in fancy marketing with huge claims to trick consumers, all backed by David Beckham.
