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 Fat Burning Stack provides a synergistic blend of nutrients that work together to optimize metabolic function, promote efficient energy production, and support healthy body composition. Bio-Avail Organ delivers targeted glandular concentrates and cofactors, while Bio-Avail Multi supplies essential vitamins and minerals like B vitamins, chromium, and magnesium. Bio-Avail Omega+ helps maintain healthy blood sugar balance and satiety with omega-3s, curcumin, and black seed oil. Together, these nutrients provide comprehensive support for a healthy, efficient metabolism.

While the Fat Burning Stack is not explicitly designed for weight loss, it can support healthy weight management by optimizing metabolic function and promoting lean body composition. By helping to maintain healthy blood sugar balance, supporting efficient energy production, and promoting satiety, this stack can help create a metabolic environment that is more conducive to maintaining a healthy weight when combined with a balanced diet and regular physical activity.

Yes, the Fat Burning 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 with your healthcare provider before starting, especially if you have any pre-existing health conditions, are taking medications, or have specific 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 energy levels, metabolic efficiency, and overall well-being within 4 to 8 weeks of consistent use. However, the full benefits of the Fat Burning Stack may take several months to become apparent as the nutrients work to optimize metabolic function and support healthy body composition. For best results, we recommend taking this stack daily as part of a consistent, long-term approach to supporting your metabolic health alongside a balanced diet and regular physical activity.

If you have a pre-existing health condition, particularly one that affects your metabolism or endocrine system, it's essential to consult with your healthcare provider before starting this or any other supplement regimen. While the ingredients in the Fat Burning Stack are generally safe and well-tolerated, some nutrients may interact with certain medications or have specific precautions for certain health conditions. Your provider can help you determine if this stack is appropriate for your individual needs and guide you on the optimal dosage and usage.
