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.
Good nutrition isn’t breaking news; it’s ancient.
Humans haven’t changed much in the past 200,000 years, but the world around us has—and not in a good way. The quality of our air, soil, water, and food has suffered considerably, leaving us far less equipped to close the ever-widening gap between what we need and what we get.
All you need to thrive—and nothing you don’t.
Most of us have patched together a cupboard full of supplements without a clear strategy or plan. The Core Plus bundle has been carefully curated to give you everything you need each day—from essential vitamins and minerals like vitamin B12, folate, magnesium, and vitamin D, to phytonutrients like bioflavonoids, carotenoids, and beta-glucans.
Add back in what modern life squeezed out.
Our ancestors’ diets were rich in the essential vitamins, minerals, and phytonutrients we need for optimal function. But declining soil quality, a growing toxic burden, and other modern challenges have made it difficult to get enough of these critical nutrients. The Core Plus bundle was formulated using the principles of evolutionary biology and modern research to fill the nutrient gaps that we face today and mimic the nutrient intakes found in an ancestral diet.
Evolutionary wisdom meets modern science.
Most supplements are made with cheap, synthetic ingredients that aren’t well-absorbed and don’t mimic the nutrients we get from food. With Core Plus, all the nutrients are food-based, naturally occurring, or bioidentical—which means they can build upon the nutrition we get from a whole-foods, nutrient-dense diet.
Proven and peer-reviewed.
The Core Plus bundle is backed by the latest peer-reviewed scientific evidence and the extensive clinical experience of Chris Kresser, a globally renowned Functional Medicine practitioner and the creator and Clinical Director of Adapt Naturals. (Learn more about Chris)
Backed by the Adapt Naturals standard.
In our increasingly toxic world, the last thing you want to worry about is a lot of allergens and artificial junk in your supplements. Core Plus is made with the cleanest possible ingredients, without common allergens like gluten, dairy, and soy, and without genetically modified organisms (GMOs). All Adapt Naturals products are manufactured in a U.S. facility that meets the NSF’s rigorous good manufacturing practice (GMP) regulatory standards. (Learn more about the Adapt Naturals standard.)
If you can’t remember why you have all those other supplements, they’re probably not doing you much good.
Take the best. Toss the rest.
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:
Bio-Avail Multi (2 capsules)
Bio-Avail Myco (3 capsules)
Bio-Avail Organ (3 capsules)
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.

The active ingredients in Bio-Avail E+, delta- and gamma-tocotrienols, are not heat sensitive. But the gel caps themselves can break if exposed to high temperatures for an extended period. We include the cold pack to prevent that from happening. The pack, and the Bio-Avail E+ bottle, will likely be warm when you receive them. That’s fine, and it won’t affect the stability or efficacy of the active ingredients. If the gel caps are broken or damaged, please reach out to email@example.com we can issue you a replacement.
All sales are final.
Occasionally a shipment may get damaged in transit. If this happened to your order, please reach out to Adapt Naturals within 7 days of receiving your package—firstname.lastname@example.org—and we’ll ship you a replacement immediately.
