What makes Bio-Avail Multi stand out?

  • Easy To Absorb

    Most multi's contain cheap, synthetic ingredients that are poorly absorbed. Bio-Avail Multi contains food-based or bioidentical nutrients foroptimal absorption and assimilation.

  • Full-Strength

    Most multi's don’t contain enough nutrients to move the needle. Bio-Avail Multinot only meets but exceeds the RDAfor most essential vitamins and minerals, so you canfeel and perform your best.

  • Great Value

    Bio-Avail Multi contains over 30 vitamins, minerals, and phytonutrients—which means you can streamline your daily supplement routine and save money and time!

Conquer nutrient deficiency and take back your health!

Did you know that humans need at least 30 micronutrients to function optimally? Virtually every process that happens in the body requires a vitamin, mineral, or other nutrient.  

This explains why nutrient deficiencies can lead to a such a wide range of problems, from low energy to poor sleep to weight gain to an increased risk of chronic disease and premature death.

Sadly, the latest research suggests that the vast majority of 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-foods 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…

Supercharge your health with full-spectrum, bioavailable nutrients.

Frankly, most multivitamins on the market aren’t worth taking. 

They’re made with cheap, synthetic ingredients, they don’t have enough of what we need (or too much of what we don’t), and they don’t contain the phytonutrients that promote optimal health and longevity.

To get the full benefit of a multi, you need highly absorbable essential vitamins and minerals and phytonutrients in a carefully balanced formula.

The Adapt Naturals Standard

In our increasingly toxic world, the last thing you want to worry about is a lot of artificial junk in your supplements. Adapt Naturals supplements are made with the cleanest possible ingredients, without gluten or GMOs. Our products are manufactured in a U.S. facility that meets the NSF’s rigorous GMP regulatory standards.

Your Questions Answered

Claiming that multivitamins don’t work is like saying “medications don’t work” or “food is good for you.” The efficacy of a multivitamin depends on the quality, form, and amount of its ingredients, and these vary tremendously from product to product. Most studies of multivitamins use generic products that can be purchased at Walmart, Costco, or other outlet stores because that’s what most Americans are buying. Bio-Avail Multi is a clinician-grade product with full-strength, superior ingredients carefully curated by one of the most respected Functional Medicine clinicians in the world, Chris Kresser. It cannot be compared to generic multis that you can find in a local store!

Each bottle contains a 30-day supply. We suggest ordering in bulk to save money and receive additional value. If you order 3–5 bottles, you’ll save 10% on each bottle and get a free one-year supply of vitamins D3/K2 for one person. If you order 6 or more bottles, you’ll save 20% on each bottle and get a free one year supply of D3/K2 for two people. You will also receive free shipping & handling when you order three or more bottles.

Most people see positive changes like more energy, deeper sleep, and better mental and physical performance within a couple of weeks. That said, nutrient deficiencies take years—or even decades—to develop, and they can take months to fully correct. We suggest giving Bio-Avail Multi at least three months before determining whether it is working for you.

Since each person's vitamin D is affected differently by sunlight, nutrient absorption from food and supplements, and mobilized body stores, there is no one-size-fits-all guideline for how much an individual needs. Some people will be fine with the 2,000 IU that is in Bio-Avail Multi, but others will need more to maintain an optimal serum vitamin D level. The same is true for K2. There is 50 mcg in Bio-Avail Multi, but people who want additional support for bone, cardiovascular, and immune health may choose to take more.  

The cost of shipping for 1 bottle is $7.99. Shipping is free for orders of 3 or more bottles.  

We ship most orders within one business day. Most orders take 2-3 days to arrive once shipped.

Bio-Avail Multi is manufactured in a U.S. facility that meets the NSF’s rigorous GMP (Good Manufacturing Practices) regulatory standards.

The recommended dose is four capsules per day taken with food. We suggest taking two capsules in the morning with breakfast and two in the evening with dinner. If you practice intermittent fasting and do not eat in the morning, you can either take your first dose with your first meal later in the day, or take it without food in the morning. (Note that a small percentage of people may feel nauseous when taking vitamins and minerals on an empty stomach.) You may also take all four capsules at once if you prefer.

As noted above, nutrient deficiencies can take years (or even decades) to develop and many months to correct. For this reason, we suggest that you take Bio-Avail Multi for at least three months before you determine whether it works for you. That said, we know that each individual is different, and we want you to be completely satisfied with your purchase. If you’re unhappy with your order for any reason, simply contact us and we’ll give you a full refund with no questions asked.

Great quality stuff!

My husband heavily researches everything we buy. He was impressed with the company and the quality of the vitamins. After taking them for only a couple of weeks, I feel an increase in energy, improved cognitive functioning, more stamina in my workouts, and an overall better sense of health. I have not taken a multivitamin in years. I highly recommend Adapt Naturals. You get what you pay for.

Hi Jennifer, Thank you for reviewing the Bio-Avail Multi. We're thrilled to hear of the positive changes you have noticed since taking this supplement. Thank you for making it Adapt Naturals! All the best.

Better mood, no illness

I started the multivitamin and colostrum at the same time about 1.5 months ago. I’ve noticed a significant increase in mood. Also, my 7 year old and I have been sick so much this last fall, but I haven’t gotten any illnesses since I started taking both and my son has been sick once. I’ve also only been taking 3 capsules a day, since I’m about 115 pounds and read somewhere it’s formulated for a 150lb person. I’ll definitely be ordering more. Would love some vitamins formulated for kids as well. :)

I Feel More Alive

Even though I have been lifting and eating clean since about 17 years old (now 33), I had always struggled with energy, sleep, inflammatory issues, and my skin to name a few things. Im just a very sensitive human physically.
I had also donated a kidney in my mid 20s which furthers my energy troubles, but ive always been looking for solutions, especially with supplements. Ive purshased the Adapt Naturals Multivitamin and Organ supplement a few times now.
I 100% feel more alive and alert when actively taking these, especially the full dose. It helps with the brain fog, fatigue, lack of motivation, just most of the things that have always slowed me down. Im a mom and run multiple small businesses, in addition to my fitness regimen, so I need all the help I can get.
They are kinda pricey and its a lot of capsules to take in a day, but to me its worth it to keep buying them, and I know they are good quality which is something ive always been willing to spend a little more on.
Ive been following Chris's podcast for some time and I love what he does and the good information he spreads, so im happy to support his supplements. Especially when they are one of the few things in life that have actually helped me to be a happier and more functional human. So thank you.

Hi Acacia, We are happy you are experiencing the benefits of our Bio-Avail Multi, especially as a single mom who needs the energy and sleep to keep up with and properly care for your child. We hope as we continue to supplement on this product you will notice other great benefits. We appreciate your review!
