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!

Your Questions Answered

The Gut Health Stack takes a comprehensive approach to digestive wellness by targeting multiple aspects of gut function. Bio-Avail Colostrum+ helps restore and strengthen the gut lining, nourish the microbiome, and balance gut immunity. Bio-Avail Organ supports the body's own digestive organs and their functions. Bio-Mag promotes relaxation, regularity, and nutrient absorption in the gut. Together, these products work synergistically to optimize digestive health from the inside out.

While this stack is not a cure or treatment for any specific condition or disease. However, it can be a powerful tool for supporting digestive health in those with a wide range of gut issues. The Gut Health Stack can help alleviate symptoms and address underlying imbalances associated with many common digestive issues by restoring the gut lining, supporting digestive function, nourishing the microbiome, and promoting regularity. It's always best to work with a healthcare practitioner to determine the best course of treatment for your individual needs.

Bio-Avail Colostrum+ and Bio-Avail Organ are made from bovine sources and are therefore not suitable for those with sensitivities or allergies to dairy or beef. Bio-Mag is made without gluten, dairy, soy, and nuts but is not certified to be free of those allergens. As always, carefully review the product label and consult your healthcare provider before starting any new supplement regimen, especially if you have known food sensitivities or allergies.

Individual responses vary, but many people notice improvements in digestion, regularity, and gut comfort within the first few weeks of consistent use. However, the full benefits of the Gut Health Stack may take several months to become apparent, particularly when restoring the gut lining, balancing the microbiome, and seeing the systemic effects of improved gut health. For best results, we recommend taking this stack daily for at least 3-6 months, ideally as part of a long-term gut wellness program.

If you are taking antibiotics or other medications, it's important to consult your healthcare provider before starting this or any new supplement regimen. While the ingredients in this stack are generally safe and well-tolerated, some may interact with certain medications or alter their effectiveness. In particular, the immunoglobulins in Bio-Avail Colostrum+ may interfere with the absorption of certain drugs. Your provider can help you determine if the Gut Health Stack is right for you and guide you on the best dosage and timing in relation to your medications.
