Core Plus is a daily stack of five products that work together to close the nutrient gap and help you perform and feel your best. The 30-day bundle includes:

Core Plus is backed by over a decade of research and clinical experience and fueled by high-quality, evidence-based ingredients you can trust.

Warning: If taking a blood thinner medication, consult a healthcare practitioner before use. (Divided dosing recommended.)

  • Bio-Avail Multi | All you need and nothing more

    A multivitamin is the cornerstone of any supplement strategy. Bio-Avail Multi is a multivitamin/multimineral and phytonutrient blend that replicates an ancestral whole-foods, nutrient-dense diet. Unlike most multis on the market made with cheap and synthetic compounds, all the ingredients in Bio-Avail Multi are food-based, naturally occurring, or bioidentical. It’s like a multi and greens and reds powder all in one!

    Warning: If taking a blood thinner medication, consult a healthcare practitioner before use. (Divided dosing recommended.)

    Bio-Avail Organ | A food-based nutrient powerhouse

    When it comes to nutrient density, edible offal and organs win hands-down. A single serving of liver meets the Recommended Dietary Allowance (RDA) for vitamin B12 for an entire week and far exceeds the daily RDA for vitamins A and B2 (riboflavin) and copper. While most of us don’t have organ meat in regular rotation, Bio-Avail Organ has you covered with a blend of five freeze-dried, bovine organs—liver, heart, kidney, pancreas, and spleen—sourced from 100% grass-fed, grass-finished, free-range New Zealand cattle. Taking Bio-Avail Organ each day is equivalent to eating about 4 ounces of organ meat a week.

    Bio-Avail Mag | The missing link for sleep and metabolic health

    Magnesium is an essential mineral for human health, involved in over 700 enzymatic reactions, and required to synthesize DNA, RNA, and proteins—the building blocks of life. It promotes sleep and relaxation, helps maintain normal blood sugar, supports bone health, and much more. Each 2-capsule serving contains 300 mg of magnesium in a chelated formula, meaning it gets absorbed quickly and is far less likely to cause gastrointestinal symptoms like loose stools and bloating, unlike inferior forms of magnesium. Studies suggest that the average American consumes 200 to 300 mg less magnesium per day than they need! We created Bio-Avail Mag to ensure you get enough of this critical and health-boosting nutrient.

    Bio-Avail Myco | Natural immune, brain, and cardiovascular support

    Mushrooms are nothing short of a natural wonder. They have a 7,000-year track record of supporting health and well-being—from protecting our brains to supporting immunity and cellular health to maintaining healthy blood sugar and cholesterol levels. Today, they’re the focus of intensive scientific research, with over 400 studies published on turkey tail alone. Bio-Avail Myco contains a blend of eight of the most researched mushrooms, including reishi, chaga, lion’s mane, and turkey tail, which are laboratory-grown for consistency, safety, and control over the growth cycle.

    Bio-Avail E+ | Promotes healthy bones and cells

    Vitamin E is an essential micronutrient that 89% of Americans don’t get enough of. Yet studies show that supplementing with the most common form of vitamin E, alpha-tocopherol, doesn’t improve health over the long term—and, in fact, can increase the risk of cancer and heart disease. Bio-Avail E+ is tocopherol-free and contains 300 mg of delta- and gamma-tocotrienols, a recently discovered form of vitamin E that has far greater health benefits—and none of its long-term risks. It can improve lipid profiles, promote cellular health, support healthy blood sugar levels, and improve bone health.

  • The majority of Americans are deficient in not just one but several micronutrients, and it can take months to restore adequate levels of vitamins and minerals once they have become depleted.1 And once you have restored optimal nutrient levels, continuing to take Core Plus daily is the best way to ensure you get all the nutrients you need to support vibrant health and longevity.

    We recommend taking Core Plus daily with food for best results and following this schedule for ease and convenience:

    With breakfast:

    • Bio-Avail Multi (2 capsules)
    • Bio-Avail Myco (4 capsules)
    • Bio-Avail Organ (3 capsules)

    With dinner:

    • Bio-Avail Multi (2 capsules)
    • Bio-Avail Organ (3 capsules)
    • Bio-Avail Mag (2 capsules)
    • Bio-Avail E+ (1 gel cap)

    Taken together, the Core Plus bundle is a powerhouse of nutrients backed by the latest peer-reviewed scientific evidence and 15 years of extensive clinical experience. It’s made with the cleanest possible ingredients—and without gluten, dairy, soy, or GMOs.

    The Adapt Naturals Core Plus bundle closes the gaps in your nutrition and lays the foundation for long-term health.

That’s fine, and it won’t affect the stability or efficacy of the active ingredients.

Bio-Avail Multi contains a substantial dose of vitamin K1/K2 (450 mcg), which may interfere with blood-thinning medications like warfarin. If you’re taking one of these medications, we recommend that you check with your medical provider before starting the Core Plus bundle and/or Bio-Avail Multi.

Impressed so far

After one month on Adapt Naturals, I am noticing an improvement in my sleep, and even some improvement with hot flashes and other menopausal symptoms, along with an overall sense of just feeling better. I plan to continue with the core bundle!

Hi Michelle, We are indeed happy to hear you are experiencing great results from our core plus bundle. We are happy your sleep and hot flashes has improved, and most importantly you are feeling better overall. We appreciate you taking the time to leave us a review!

Laura P
Accelerated my healing and keeping me in great shape

I started the Adapt Naturals Core Plus bundle in the fall when I learned that my nagging injury was a tear in my hamstring. As a triathlete it was hard to slow down and focus only on Physical Therapy. In addition I started the Core Plus bundle. My PT was suprised at how fast I healed and how quickly my recovery progressed, and now I'm trained up and ready to compete in triathon again, healthier than ever.

Hi Laura, We're elated to hear about how our core plus bundle has helped you with healing from your injuries. Everyone's hope is to have a healthy life and we are glad our core plus bundle is giving you the benefits needed for a healthy life. We appreciate your review!

Scott Blue
Really solid and activating

So dig my Adapt Naturals bundle. As a mid-fifties father of two younger / youngish kids, it made a complete difference in my overall energy and sense of physical wellbeing.

Hi Scott, Thank you for taking the time to share your experience with the core plus bundle. We're thrilled to hear that you had a positive experience and that our products were able to help with your overall well being!

Jonathan Taylor
Recovering my speed of recovery

I’m a 58 y-o male, and in recent years I had difficulty juggling work stress, demanding workouts, sleeplessness, and physical recovery. Cortisol disregulation and chronic soreness were the order of the day. Adapt Naturals Core Plus Bundle to the rescue! I bounce back faster than ever. The only wrinkle for me was that I had to taper up the Myco supplement; the full dose puffed my eyes right up on Day 1. A gradual increase did the trick. Thanks for helping me get my zip back! -Jonathan

Hi Jonathan, We are thrilled to hear of how impactful the core plus bundle has been to your health. We hope as time goes by you will notice other great changes. We appreciate your review!

Margaret Green
Too Much?

Isn't a multivitamin taken simultaneously with an organ supplement overkill?

Hi Margaret, Chris designed Bio-Avail Multi and Bio-Avail Organ to be taken together (along with the other three supplements in the Core Plus bundle). Thank you for your review!
