Why choose Core Plus Bundle?

Our modern diets often fall short of providing the optimal amounts of essential nutrients our bodies need to function at their best. With the Core Plus Bundle, you can overcome nutrient deficiency and support your overall health and well-being. We've done the research, so you don't have to!

Formulated to Replicate Optimal Ancestral Diets

Changes in dietary patterns, declining soil quality, and a growing toxic burden have made it increasingly difficult to obtain adequate nutrients from our daily food intake. The Core Plus bundle is designed to address these challenges by providing a comprehensive blend of essential vitamins, minerals, and phytonutrients that closely resemble those found in an ancestral, whole-foods diet.

Harness Years of In-Clinic Experience and Ancestral Wisdom

Backed by Adapt Naturals' 15 years of in-clinic experience and dedicated to creating supplements that make a meaningful difference, Bio-Avail Omega+ combines cutting-edge research with insights from ancestral wisdom to bring you a premium-quality supplement.

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.

Starting in the fall of 2023, we’re 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!

Natural vitamins make all the difference

Store bought vitamins turn my pee different fluorescent colors. Adapt Naturals is not just higher quality, it's practically in a different category entirely. I open the capsules and mix it with my coffee and protein powder. I really like the taste. This is now part of my overall health regimen. At my age I need to take every measure possible to retain my health. When I decided to take vitamins I knew I wanted to do it differently. I thought to myself: Who is the most trusted name in nutrition? It's Chris Kresser.

Hi Armen, Thank you for trusting us with your health. We are thrilled to hear our Core Plus bundle is working great for you even when you open the capsules. Thank you for sharing your experience with us. All the best in your supplement journey!

Hi Joel, Thank you for recommending our core plus bundle. We are happy your energy, sleep and overall wellbeing has improved since you started this supplement. Thank you for sharing your experience. Best of health!
