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 Thyroid Support Stack provides a comprehensive blend of nutrients essential for optimal thyroid function. Bio-Avail Organ delivers targeted glandular concentrates and cofactors, while Bio-Avail Multi supplies key vitamins and minerals like iodine, selenium, and zinc. Bio-Avail Omega+ supports a healthy cellular response and immune balance, which are crucial for overall thyroid health. These products work synergistically to nourish and support your thyroid from multiple angles.

The Thyroid Support Stack is designed to provide overall support for healthy thyroid function and is not intended to diagnose, treat, cure, or prevent any specific thyroid conditions. If you have a diagnosed thyroid disorder or suspect you may have one, it's crucial to work with a qualified healthcare practitioner for proper evaluation, monitoring, and treatment. This stack can be a valuable complement to a comprehensive thyroid care plan but should not be used as a substitute for professional medical advice and care.

Yes, the Thyroid Support Stack is formulated with safe, well-tolerated, and nourishing ingredients that are generally suitable for long-term use when used as directed. However, as with any supplement regimen, it's always a good idea to consult your healthcare provider before starting, especially if you have a pre-existing thyroid condition, are taking medications, or have any other health concerns. It's also important to monitor your individual response and adjust your dosage as needed under the guidance of a healthcare professional.

Individual results may vary, but many report feeling a difference in their overall well-being, energy levels, and metabolism within 4 to 8 weeks of consistent use. However, the full benefits of the Thyroid Support Stack may take several months to become apparent, as the nutrients work to optimize thyroid function and support overall wellness. For best results, we recommend taking this stack daily as part of a consistent, long-term approach to nourishing your thyroid health.

If you are currently taking thyroid medication, it's essential to consult with your healthcare provider before starting this or any other supplement regimen. While the ingredients in the Thyroid Support Stack are generally safe and well-tolerated, some nutrients may interact with certain medications or affect your thyroid hormone levels. Your provider can help you determine if this stack is appropriate for your specific situation and guide you on the optimal dosage and timing in relation to your medication schedule.
