Your Questions Answered
I’ve been using the core plus bundle approximately five years now. I really like how easy it is to prepare my daily supplement regimen. I’ve noticed since the bundle that my memory is improved and my health seems to be much better. I would highly recommend the court plus bundle to anybody looking to streamline their supplement regime. The products all seem to be very high-quality.
Hey Terry,
Five years with the Core Plus Bundle and improved memory noticeably better health and a streamlined supplement routine...that is the whole vision behind the bundle and you are living it! Chris designed the Core Plus as the five supplements he believes are most beneficial for most people and when all five are working together the effects really do compound in a meaningful way. High quality across the board is something we never compromise on and hearing it from a five year customer means everything. Thank you so much for sharing and for your loyalty!
Black spots growing in the capsules
Hi Michael, Thank you for providing this feedback. Our manufacturer has told us that due to several active ingredients with high moisture content, combined with low levels of silicon dioxide (adsorbents) in the Multi, certain raw materials will sometimes change in color over time, especially when combined with high humidity and/or certain storage conditions.They are perfectly fine to consume.
It’s been about a month now and I feel energetic, sharp, happy, less leg cramps, overall very happy with these vitamins! OH and I’m sleeping great. I have paired the start of the vitamins with a month long trip to Kauai, I’m excited to see how I feel getting back to spring ski in Alaska with harsher environment!
Hi Jp, We are glad you are feeling good overall. We hope as you continue to take our supplements you will notice other positive changes. Thank you for leaving us a review!
It's been almost a full month for 3 family members testing the Core Plus Bundle, and so far so good. No major reactions, but 1 of us did get a little nauseous after taking a set of pills with very little food intake once. We need 3 sets of this bundle, but we're sharing 1 set due to the cost. I've added 2 more bottles of E and 1 more bottle of the Multi to our subscription for now.
Hi Nancy, we are glad to hear your family is benefiting from the Core Plus Bundle. Occasionally, certain individuals may be sensitive to Magnesium as it can cause some nausea on an empty stomach. Hopefully you continue to experience positive benefits from the Adapt Naturals line. Thanks for your review!
Navigating the supplement world is challenging these days - so much conflicting information, safety and purity concerns, lack of impact...I keep coming back to Adapt Naturals because I trust the brand, and it consistently delivers exactly what it is supposed to.
Hey Shae,
Trust consistency and results in a supplement world full of noise and conflicting information is exactly what we work every single day to deserve and we are so grateful you keep coming back. The Core Plus Bundle covering nutrition gut health omega-3s magnesium and mushrooms all from one company with third party testing behind every formula is exactly the kind of simplified reliable stack Chris designed it to be. Thank you so much for sharing!
As far as I can tell the product is effective. My go to Multi. Also feel confident about the magnesium and mushroom blend. Have always felt the ingredients were high quality.
Hey Kenneth,
Sounds like the Core Plus Bundle is doing exactly what Chris designed it to do! The combination of Bio-Avail Multi Bio-Avail Mag and Bio-Avail Myco working together every day really does create a comprehensive foundation that covers nutrition energy and cognitive function all at once. High quality ingredients throughout is something we never compromise on and we are so glad it shows. Thank you so much for sharing and for your loyalty!
I feel good taking these supplements. I’ve been consistent with them for a while and I feel great!
Hey Nicole,
Consistent for a while and feeling great is what the Core Plus Bundle is doing exactly and what Chris designed it to do! When all five products are working together consistently the effects compound in a really meaningful way and feeling genuinely good is the whole goal. We are so glad you are there and thank you for your loyalty and for sharing!

Hey Gisele,
Better energy and better bowel movements are honestly two of the most foundational things you can improve and we love that you are noticing both! The Core Plus Bundle was designed as the five supplements Chris believes are most beneficial for most people across the board and when everything is working together like that the whole body tends to respond. So glad you are feeling the difference overall and thank you for sharing!
Great product
Hey there,
Thank you so much for the 5-star review! We're thrilled to hear you're loving the Core Plus Bundle!
This bundle is truly the foundation of comprehensive wellness—combining our Bio-Avail Multi for essential vitamins and minerals, Bio-Avail Organ for ancestral nutrition from five grass-fed bovine organs, Bio-Avail Myco for cognitive support with eight organic mushroom extracts, Bio-Avail Mag for highly absorbable magnesium, and Bio-Avail E+ for cardiovascular and immune health with powerful tocotrienols.
You're giving your body an incredible array of nutrients to support optimal health from every angle. We're so grateful to have you as part of the Adapt Naturals community!
Subscribing to the Core Plus bundle gives me the confidence that I’m getting a quality product, (therefore not wasting my money) and that my supplement regimen is thorough. I trust the integrity of Chris’ research and the company. This is so important now, as we are in a time of questionable information in the product space and beyond!
Hi Lori,
Thank you so much for this thoughtful feedback. It means a lot to us that you feel confident and supported by the Core Plus bundle. We created it to simplify supplementation and fill modern nutrient gaps with deeply bioavailable ingredients — so you can focus on feeling your best, without second-guessing quality. We’re honored to have your trust!
After religious taking this bundle my ANA came back normal. My energy levels are great and my skin looks great. Love these supplements!
Hi Marjorie,
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.
We're thrilled you're seeing such meaningful results!
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.
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!
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!
I have been taking the supplements for about three weeks and I definitely notice an improvement in the way I feel. My gut health is definitely better. Hope my arthritis will continue to improve.
Hi Ann. We are thrilled to hear you have noticed improvements in the way you feel and your gut health. Thank you for trying our Core Plus Bundle and sharing your experience. All the best!
I've been taking the core plus bundle for quite some time. I trust in the quality of the product and I feel good knowing I'm giving my body the nutrients it needs. Feeling energized and sleeping well. Thank you.
Hi Nicole, We are indeed pleased to know you are getting the benefits you need from our Core Plus Bundle. Thank you for sharing your experience with us!
I've been taking supplements from the Core Plus bundle for about 1 year. My energy is up, my sleep is improved, and I feel good knowing these products are good quality
Hi Nicole. We are thrilled to hear you have noticed improvements in your energy and sleep. Thank you for trying our Core Plus Bundle and sharing your experience. All the best!
Core Plus Bundle has reduced my appetite and cravings. Very pleased but I would like to know how the bundle works to accomplish that goal?
Hi Terri! We’re thrilled to hear that your Adapt Naturals supplement regimen is working so well for you :) This is a difficult query for us to answer—biochemistry is complex, and individual reactions to nutrients can vary quite a bit. But generally speaking, it could simply be that the addition of quality, bioavailable supplements provides your body with enough nutrients to thrive. Another possibility is that Bio-Avail Multi contains chromium, which is known to curb both hunger and food cravings, as evidenced by this study. That said, there is really no way for us to answer this question definitively—we’re just happy to hear it! Please take good care.
I’m very pleased!
Hi Katrina, Thank you for sharing your experience with our Core Plus Bundle. We are happy you are loving our supplements. Best of health!
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
Hi Laura, We hope you will experience all the benefits of our Core Plus Bundle. Thank you for your continued support and for leaving us a review!
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!
Knowing you're getting a high quality supplement and you don’t have to worry about the ingredients coming from a questionable source is worth every penny.
