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!

Supplements I can trust feels amazing!

After listening to Revolution Health Radio for so many years, I trust Chris Kresser's work and ethics so much. As a practitioner myself, I can share this line of products with confidence of the efficacy and quality. Personally, I recently started taking the supplements and it feels great to know I'm doing all that I can to optimize my health. Thanks Adapt Naturals

Totally felt the effects deep inside our bodies

My
Partner and I are both on board with the Core Plue Bundle! It was no longer that 3 weeks into daily use that we each noted shifts in daily positive energy
Levels, better sleep, and more daily mental clarity. We are always skeptical when trying new nutritional prodects, but this grouping of products has been notable since early in the first month.
We each are seeing positive shifts where it really counts on our daily physically active work lives.
This product has obviously been well thought out and formulated with quality ingredients. They work!

Hi Martha. We are thrilled to hear you have noticed improvements in your sleep, energy levels and even mental health! Thank you for trying our Core Plus Bundle and sharing your experience. All the best!

Great but tough to gauge results

I like the composition of products and packaging and idea behind adapt naturals. I am glad I checked them out. I haven’t yet to see any results, because it is hard to gauge the results of taking supplements on a day to day basis especially when I take 10 other products as well? Guess I feel the same, haven’t noticed any noticeable performance degrade or upgrade, but I guess I am going to keep the course. I mean don’t get me wrong the supplements are very expensive especially also since the serving size for most products in the core bundle are more than a single pill per each day. It all adds up pretty fast so have to figure out how it’s sustainable to keep doing this month over month.
I also like that the supplements come in zip lock bags made from sustainable bags, and one can buy glass bottles for a price but yeah it make it even more expensive to do that
