The four things you'd lose by not watching

TL;DR

The four things you'd lose by not watching

4 items
1

The top-selling creatine gummy on Amazon contained zero actual creatine, exposing massive fraud in a category where consumers can't feel the difference daily.

2

A protein powder sold in high-end grocery stores claimed 21g protein per serving but delivered only 3g, with the missing 18g filled by cheap carbohydrates.

3

Consumers can protect themselves by asking brands for a certificate of analysis (COA) and stability study data, and by looking for a GMP mark on the packaging.

4

Multivitamins and gummy supplements are especially prone to degradation and chemical incompatibility; simple powders in a bag are far less likely to be fraudulent or lose potency.

Protocols

Concrete recipes — what, when, how much, and why

4 items

Check for a GMP certification mark

WhatLook for a 'GMP' (Good Manufacturing Practices) mark on the supplement packaging or website.
WhenWhen choosing a supplement brand.
DoseN/A
For whomAll consumers looking for baseline quality assurance.
WhyGMP certification indicates the manufacturing facility follows strict quality control protocols, including mandatory testing.
CaveatsGMP alone doesn't guarantee every lot is tested for potency and stability; it's a minimum standard, not a foolproof guarantee.

The lab mentioned that GMP facilities are required to perform a certain level of testing, which makes them a better choice than unknown facilities. Combined with a COA and stability study, GMP gives a solid foundation. Mike was specifically told to 'look for a GMP mark' as a quick screening tool.

I would definitely look for a GMP mark.

Request stability study results

WhatAsk the brand for stability study data that tests the product's active ingredients at multiple time points during its claimed shelf life.
WhenWhen buying supplements, especially gummies, liquids, or multivitamins with long expiration dates.
DoseN/A
For whomInformed consumers who want the highest confidence, especially for complex formulations like multivitamins.
WhyConfirms that the product maintains label claims not just at production but through the entire shelf life, overcoming degradation issues.
CaveatsNot all good brands have public stability studies; however, they should be willing to share if they conduct them. Smaller brands might not do them, which doesn't guarantee they're bad but increases risk.

The lab explained that a COA is only a snapshot, while stability studies show the big picture. Active ingredients like B vitamins can degrade fast under heat and pressure during manufacturing. Without a stability study, a product might be fully potent at day zero and nearly useless at 9 months. The best brands combine a COA with a stability study and GMP. Mike said this was a new and valuable concept for him, and he'd start looking for it.

Mechanism

Stability studies account for chemical degradation over time, temperature fluctuations, and incompatibilities in the product matrix, ensuring the listed dose is available up to the expiration date.

Personal experience

Mike did not share a personal stability study experience, but his friend's declining vitamin D levels exemplify what happens when stability is ignored.

I would say stability studies paired with a COA, paired with you know, good manufacturing practice, co-packers, which most brands will highlight that as a selling point. Those are the things that you know, I look for now.

Also said
“A stability study basically says we're going to test this product over the period of the shelf life.”— Core definition of what the study does.

Buy from retailers with strict testing requirements (e.g., Whole Foods, Amazon moving forward)

WhatPurchase supplements from retailers that mandate third-party testing and verification, like Whole Foods, and increasingly Amazon.
WhenWhen shopping for supplements, especially online.
DoseN/A
For whomAll supplement consumers.
WhyThese retailers act as gatekeepers, filtering out many fraudulent products before they reach shelves.
CaveatsNot infallible (the underdosed protein powder was sold in a high-end retailer), but it significantly reduces risk. Amazon's new policies are still rolling out.

The lab rep noted that where you buy matters 'a tremendous amount.' High-end retailers like Whole Foods require some level of proof from brands. Amazon is beginning to shift the same direction because the creatine gummy fiasco threatened their business model: if customers lose trust, they go elsewhere. Eventually, a rigorous testing standard at major retailers could make fraudulent supplements extremely rare, like finding unapproved chemicals in paint today.

Whole Foods and these other retailers they do require some level of proof. So, I would say where you buy actually matters a tremendous amount.

Also said
“Amazon is beginning to shift way more in this direction because it's a huge I would argue risk to their business, where if you learn that anything can be peddled on Amazon I just don't go on Amazon.”— Explains why even Amazon is being forced to act.

Perform off-shelf testing if you own a supplement brand

WhatHave your own products pulled from a retail shelf and sent to an independent lab for testing to verify that the supply chain hasn't degraded your product.
WhenPeriodically, as part of brand quality assurance.
DoseN/A
For whomSupplement brand owners and operators.
WhyBrands lose control after manufacturing; off-shelf testing catches degradation or mishandling during distribution.
CaveatsAdds cost, but it's the ultimate responsibility of the brand to ensure efficacy up to expiration.

Mike asked whether brands should send people to stores to buy samples and test them. The lab team agreed that it's a good idea and the brand's ultimate responsibility. Supply chain mishandling (heat, light, humidity) can degrade actives even if the product left the factory perfect. Off-shelf testing closes that loop.

I think if you own the brand, it is your ultimate responsibility to ensure efficacy up to point of expiration at all different call it points throughout your supply chain.

Lines worth pulling out — contrarian, specific, or perfectly phrased

The number one seller on Amazon did not have any creatine in their gummy.
Stark, headline-grabbing revelation that the top product was 100% fake.
To miss by that much, you have to intentionally be filling it with something else.
Mike's blunt assessment that the protein powder fraud was deliberate, not an accident.
I suspect they actually were putting D vitamins into the product but through some like matrix issue there's some oxidation happening and then just after a few weeks... there's just no more D vitamins in it.
Mike's sharp hypothesis of what likely happened in his friend's case, showing he grasped the degradation problem.
I'm taking it now more consistently than I've ever taken it before, cuz with the gummies, it's so easy.
Demonstrates how even a knowledgeable expert can be drawn to a fraudulent product by convenience.
