Bio-Avail Multi is a multivitamin/multimineral and phytonutrient blend that mimics nutrient intakes found in an ancestral, whole-foods, nutrient-dense diet.

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

Bio-Avail Multi highlights:

B vitamins in their most bioavailable forms (e.g., folate instead of folic acid, methylcobalamin instead of cyanocobalamin, pyridoxal-5-phosphate [P5P] instead of pyridoxine)

2,000 IU of vitamin D

Full-spectrum vitamin K blend, with K1 and K2 (MK-4, MK-6, MK-7, MK-8, MK-9)

Vitamin E as delta- and gamma-tocotrienols, which are far more potent (and safe) than tocopherols

A low dose of calcium and no iron, alpha-tocopherol, or iodine (since supplementing with these nutrients at high doses can be problematic)

✔ Highly bioavailable chelated forms of magnesium, zinc, copper, and other minerals

✔ A concentrated phytonutrient blend with lutein, lycopene, wild blueberry complex, muscadine grape extract, broccoli seed extract, and citrus bioflavonoids

✔ And so much more!

    Closes the Nutrient Gap and Clears the High Bar for Optimal Health

    What makes Bio-Avail Multi stand out?

    Why make Bio-Avail Multi part of your daily routine?

    Diet patterns have changed dramatically in the modern world. Sixty percent of the calories the average American consumes now come from ultra-processed foods like flour, sugar, and seed oils, which are virtually devoid of nutrients. This explains why recent statistics suggest that most Americans are deficient in not just one but several micronutrients.1 Our ancestors, on the other hand, enjoyed a far more nutrient-dense diet. Bio-Avail Multi helps close the gap between the world we evolved to live in and this one by providing critical nutrients that are hard to get in the average American diet.

    Not getting enough of the essential nutrients we need has been linked to a wide range of chronic diseases, from type 2 diabetes to cardiovascular disease to osteoporosis to Alzheimer’s disease. It’s not enough to occasionally get a good dose of nutrients and hope for the best. Taking Bio-Avail Multi every day can ensure your body has what it needs to maintain optimal health in the face of overwhelming stress and inconsistencies in the diet.

    Lots of multis look good on paper but come up short in the long run. Bio-Avail Multi contains naturally occurring or bioidentical nutrients that your body can easily use to promote and sustain optimal health.


    Bio-Avail Multi is best taken with food. We recommend taking two capsules with breakfast and two with dinner.

    Technically, yes. But some of the nutrients in Bio-Avail Multi have a bitter taste, so doing this may alter the flavor of whatever you are adding it to.

    Bio-Avail Multi was formulated for adults, or kids 16 years or older. We do not recommend giving Bio-Avail Multi to kids younger than 16.

    Boosts Energy

    I've been taking this supplement for several months now and do see a clear improvement in my energy level.

    Hi Mary, Energy is everything! We are glad you have noticed a boost in your energy levels over the past months since taking Adapt Naturals supplement. Thanks for your review!

    A supplement that saves time, saves money, and is trustworthy

    My family takes Chris Kresser's supplements - and it makes it so we have far less to buy and to swallow every day than before. These are great and if you know Chris, he always talks about the importance of nutrients being bio-available, something critical but not always true about the supplements you might think are helping you. Get these to be sure.

    Hi Jonathan, It's great to know you and your family are taking the Bio-Avail Multi and loving it. Thank you for taking the time out to leave us a review!

    A great multi vitamin

    I’ve been waiting to find a multi vitamin I can feel good about. I’ve been following Chris for about 12 years and when he came out with this, I decided to put both myself and my husband on it. We only take 2 a day a piece but we feel pretty good in general and have remained healthy all winter. We are both over 65 and eat an ancestral diet for the most part. Very happy with this product!

    Hi Pamela, It's great to hear you and your husband are feeling healthier after taking our Bio-Avail Multi. We hope you will continue to benefit from this great supplement. We appreciate you leaving us a review!

    Love this multi

    I have been taking this multi daily for a few months and my skin is clearer and more radiant, even my fine lines aren’t as noticeable. Also I feel better and have a little more energy to keep up with my kids. I wish there was a children’s vitamin from Adapt!

    Hi Melissa, We're glad to hear of the noticeable difference in your skin and energy from taking The bio-Avail Multi. We may look into creating a brand for kids in the future, so they too can experience the wonderful benefits. Thank you for your review!

    Fantastic Multi

    You will not find another multivitamin with all these wonderful ingredients. It has so many adaptogens and anti-aging components along with the essential vitamins and minerals in appropriate ratios. Four a day gives you good quantities and is easy to split between AM and PM meals. I trust Chris to source from clean ingredients. I have followed him for a long time and know he is ethical and trustworthy. I think this multi is a very good value too. So happy to have this multi!

    Hi Gayle, Happy to hear you are enjoying the Bio-Avail Multi, we appreciate your trust in Adapt Naturals. Thank you for taking the time out to leave us a review!
