Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!
