See What Others Are Saying About Core Plus
Energy boom
“This is going to sound crazy, but in one week I noticed a difference in brain functioning! And when I miss a dose I see return of the cloud. I have taken supplements by wisdom and faith my entire life, trusting that it's what I don’t see in myself that is the result. And reason. This is the first time I have seen my body respond so obviously and positively. Thank you Chris for all you do. Thank you.”
Karen R. - Verified Buyer
Brain Function
“I noticed an improvement in my memory within the first month.”
Patricia C. - Verified Buyer
Increased energy
“I have been taking the Core Plus bundle religiously for 1 and a half months now. After just 1 month I felt an increase in energy and my mental capacities increased! My focus is improving and with that, my motivation has increased. Other nice changes include more regular bowel patterns and my random foot and leg cramps have not returned during this period. I am overall pleased with this product. Thanks you to Chris and his team.”

Bio-Avail Multi: A Multi + Greens & Reds Powder in One Bottle
A multivitamin should be the cornerstone of any brain health program.
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!
Bio-Avail Organ: A Food-Based Nutrient Powerhouse
When it comes to nutrient density, organ meats 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 eat organ meats regularly, 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 daily is equivalent to eating about 4 ounces of organ meat a week.
Bio-Avail Myco: Brain, Immune 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.
Bio-Avail Myco is a blend of the eight mushrooms that have shown the greatest health benefits in scientific studies: reishi, chaga, lion’s mane, cordyceps, maitake, shiitake, agaricus, and turkey tail.
Bio-Avail Mag: The Missing Link for Sleep and Metabolic Health
Magnesium promotes sleep and relaxation, helps maintain normal blood sugar, supports bone health, and much more.
Each 2-capsule serving of Bio-Avail Mag 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 daily than needed! We created Bio-Avail Mag to ensure you get enough of this critical and health-boosting nutrient.
Bio-Avail E+: Promotes Healthy Skin, Bones, and Cells
89 percent of Americans don’t get enough vitamin E. But supplementing with the most common form, alpha-tocopherol, has been linked to an increased risk of heart disease and cancer.
Bio-Avail E+ is contains 300 mg of delta- and gamma-tocotrienols, a recently discovered form of vitamin E that has greater health benefits than alpha-tocopherol—and none of its long-term risks.
It can protect the brain, improve lipid profiles, promote cellular health, support healthy blood sugar levels, and improve bone health.
Learn What The Core Plus Bundle Can Do For You
Conquer nutrient deficiency and take back your health!
Did you know that humans need at least 40 micronutrients to function optimally? Virtually every process that happens in the body and our brains requires a vitamin, mineral, or other nutrients.
This explains why nutrient deficiencies can lead to a wide range of problems, from low energy to poor sleep and weight gain to an increased risk of age-related disease like dementia and Alzheimer’s and premature death.
Sadly, the latest research suggests that most Americans fall short on not just one but several essential vitamins and minerals.
Add back in what the modern world has squeezed out.
Our busy, fast-paced lives make it difficult for most of us to eat a clean, whole-food diet 100 percent of the time.
Even if we do, declining soil quality, a growing toxic burden, and other challenges in the modern world have made it difficult—if not impossible—to meet our nutrient needs through food alone.
Supplements can help close the gaps and ensure that we’re getting all of the nutrients we need to thrive and live a long, healthy life.
But not just any supplements will do… appears here.
Supercharge your health with full-spectrum, bioavailable nutrients.
Frankly, most supplements on the market aren’t worth taking.
They’re made with cheap, synthetic ingredients, don’t have enough of what we need (or too much of what we don’t), and don’t contain the phytonutrients that promote optimal health and longevity.
To truly benefit from supplementation, you need food-based, highly absorbable nutrients that cover all of the bases—from essential vitamins and minerals like B12, vitamins C and D, iron, zinc, and magnesium to plant nutrients like bioflavonoids, polyphenols, and beta-glucans.
The Core Plus covers your bases with the nutrients you need to feel and perform your best and live a long, healthy life.
Don't just take our word for it...
