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 Longevity Stack takes a multi-pronged approach to optimize health span and promote graceful aging. Bio-Avail Multi lays a foundation of essential nutrients, Bio-Avail Omega+ revitalizes cells and tissues, and Bio-Avail Colostrum+ supports immune function and gut health. Together, these products work synergistically to nourish, protect, and rejuvenate the body for lifelong vitality.

Yes, all three formulas are free from major allergens like gluten, dairy, soy, and nuts. However, Bio-Avail Omega+ contains fish oil, so it would not be suitable for someone with a fish or shellfish allergy. As always, carefully review the label and check with your healthcare provider if you have concerns.

Many report increased energy, focus, and well-being within the first month. However, most anti-aging effects are seen with consistent long-term use over a period of several months. The nutrients and compounds in this stack work best when taken daily to protect and rejuvenate cells, tissues, and organs.

This stack is designed for all adults looking to enhance their health span and age more gracefully. While it's never too early or late to optimize your longevity, most people begin to notice the effects of aging in their 30s, 40s, and beyond. The Anti-Aging Stack can help you feel your best at any age.

The recommended dosage is four capsules of Bio-Avail Multi, two soft gels of Bio-Avail Omega+,  and one scoop of Bio-Avail Colostrum+. Please see the product packaging for more specific dosing instructions. Always start with the suggested serving size and then adjust if needed with the guidance of your healthcare provider.
