Following news earlier in April that multiple supplements sold on Amazon are impersonating the NOW brand, as well a second prominent industry supplement brand, another report of counterfeit products has been issued.

As Karen Howard, CEO, Executive Director, Organic & Natural Health Association (O&N Health), noted in WholeFoods Magazine's 2022 Person of the Year feature on Quality Activists: “Of course, everyone expects enormous competition on the world’s largest online retail platform. However, counterfeits litter search results, even with the new C of A requirements. They also have a major issue when it comes to illegal claims. If you type in ‘supplements that treat’ (or cure), you’ll have lots of purchase options.”

The latest issue to come to light: Fungi Perfecti reported the discovery of multiple unauthorized accounts on selling counterfeit products using the brand name Host Defense Mushrooms. Fungi Perfecti conducts routine brand control efforts, and during this process the company began investigating several unauthorized sellers. Fungi Perfecti spotted irregularities in both product packaging and contents inside the capsules.

Four Host Defense products are being imitated: 

  • MyCommunity 120-ct
  • Stamets 7 120-ct
  • Lion's Mane 120-ct
  • Turkey Tail 120-ct

Fungi Perfecti stressed that some of the counterfeit products tested positive for two known allergens: soy and gluten. Authentic Host Defense Mushrooms supplements are gluten-free and are not formulated with soy, the company said.
