Inside The Lab That Busts Fake Supplements (Huge Problem)

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.

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.

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.

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.
