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 (3 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.

These supplements have made quite a difference

I am 75 and in very good health, but always willing to try something new that would 'bump me up' in terms of energy and vitality. After six weeks on Adapt Naturals I have an increased level of energy and I really notice the difference, especially in my workouts at the gym.

Rebecca Henn
Some problems with the delivery, but so far so good

So far I am liking the Adapt Naturals Core Bundle. I wanted to try it out for 3 months straight, but there were some issues with delayed delivery, so I had a month break after taking them for a month. I think my sleep is better and I definitely feel good in that I am doing something proactive about my nutrition that is difficult to get strictly through diet.

Hi Rebecca, We are so sorry that there was a delay on your package.We are indeed happy to hear you are liking the core plus bundle and that you are feeling the benefits. We appreciate your review!

Jessica Flory
AMAZING product!

I am absolutely sold on the Core Plus Bundle! I have taken many multivitamins and supplements and have never taken any that have made such a difference in my well-being. I was dealing with heart palpitations, poor sleep, dizziness when standing, among other issues. Since taking the Core Plus Bundle, my issues are GONE!! I am absolutely amazed and recommending this product to everyone I know. Love it!!!

Hi Jessica, it's a pleasure for us to know you have noticed positive improvements since taking core plus bundle. we are happy we could create a product that supports optimal health in adults. Thanks for leaving us a review!

Good to GREAT

I felt good before starting the Core Plus bundle…but after taking it for 2 months, I feel great. Improvements I have noticed: better sleep, better recovery from hard exercise efforts and I easily dropped that last 5 stubborn pounds due to lowered cravings. I do not crave salty or sweet foods like I used to. Lastly, more regular bowl movements.

The bundle is an investment in my healthy longevity!

I am a 50 year old female and I feel like my 30 year old self. My body composition has shifted too. I work out regularly (lots of zone 2 cardio and weights). After taking the bundle for 2 months, my gains in the weight room have increased and the number on the scale has decreased.

Hi H, Great to hear of the positive effects you have noticed as it relates to sleep, recovery, and weight loss since taking the core plus bundle. We hope you will continue to experience these positive effects along with other great benefits. Thanks for your review!
