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 Multi not only meets but exceeds the RDA for most essential vitamins and minerals, so you can feel 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.

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!

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.

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.

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.

Each bottle contains a 30-day supply.

Best Multi I Could Find on the Market

I looked for a long time for a high quality, bio-available multi with the right mix of things. Inevitably most had something I didn’t want like iron or adaptogens like ashwagandha. I want a multi I can take for a long period of time as the foundational piece of my supplements routine. Adaptogens should be customized to the user and appropriately modulated. And not everyone needs more iron.

Anyway, I’m loving this multi. I love that it has a healthy dose of vitamin D, zinc, and selenium so I can stop buying those things separately. I love that it doesn’t come in a plastic bottle. I love that it has superfoods like blueberry and broccoli sprout extract. Mostly I just feel good taking it. I can feel a pull from my body instead of resistance….which is always something to pay attention to.

P.S. I also love that it’s a capsule and not one if those giant hard to digest tablets.

Hi Melanie,

Thanks for your great review!

This is exactly why we created Bio-Avail Multi: a clean, comprehensive formula without the extras you don’t want (like iron or adaptogens), and loaded with the bioavailable nutrients your body does need daily. Thanks for doing your research—and for choosing us!

Anchor

Adapt Naturals multivitamin is my anchor. I struggle with a compromised immune system and know the bio-availability of the vitamins and minerals contained in Adapt Naturals at the very least keep me functional. I believe I would tank without these.
