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.

ANA normal!

After religious taking this bundle my ANA came back normal. My energy levels are great and my skin looks great. Love these supplements!

This is incredible—thank you for sharing! The Core Plus bundle is built to support immunity, energy, and foundational health with ingredients like tocotrienols, bioavailable B vitamins, and colostrum.

Going to take a little adjusting too

I am very excited that I have made my first supplement purchase and I KNOW I will benefit from them. However, it’s going to take a little adjusting too. I started with my Multivitamin and then started the MYCO 8 Superfood mushrooms. What I experienced was extreme bloating and discomfort in my abdomen. So I have taken a break.
Still very excited to take them and get healthier.

Hi there,

Thanks for sharing your experience starting with the Core Plus Bundle! It's common to need an adjustment period when beginning new supplements, especially with concentrated nutrients like those in Bio-Avail Multi and Bio-Avail Myco. Many customers find success by starting with a lower dose - try taking half the recommended amount for 1-2 weeks, then gradually increasing to the full dose. And taking them with food can help minimize any digestive adjustment. Feel free to reach out if you need more tips for getting started.

Core plus bundle

The core plus bundle was a great way to try all the products. I now know, I love them all and I’ve had nothing, but better health and sleep since purchasing.

Hi Tari,

Thank you for sharing your experience with the Core Plus Bundle! It's wonderful to hear that you're seeing improvements in both your health and sleep quality. This is exactly why we designed our products to work together - the combination found in the Core Plus Bundle provides comprehensive nutritional support to help fill the gaps in modern diets. Getting better sleep is a fantastic benefit that many of our customers report, likely due to the balanced blend of nutrients supporting your body's natural rhythms.

Keep enjoying your journey to optimal health!

Amazing!

I have the MTHFR gene, and since I found that out, I’ve been searching for supplements that are methylated and are more bioavailable, particularly methylfolate. I heard about adapt naturals through a podcast, and based on what he was saying about the bioavailability of these supplements, as well as the wide range of components in them, I decided to try them out. Boy, I was so surprised when I started feeling so much better…my mind was clearer, I was a loooot less tired every day, and even was able to stop all other supplements I was taking and just narrow it down to this core bundle. It’s so worth the money, and I’m so glad I tried it!

Hi Heather, Thank you for sharing your experience with us. It's great to hear you are noticing a difference. We hope as you continue supplementing on the Core Plus Bundle, you will notice a greater difference. We appreciate your support to Adapt Naturals!
