Why Choose Bio-Avail Multi?

Our modern diets often fall short of providing the optimal amounts of essential nutrients our bodies need to function at their best. With Bio-Avail Multi, you can overcome nutrient deficiency and support your overall health and well-being. We've done the research, so you don't have to!

Formulated to Replicate Optimal Ancestral Diets

Changes in dietary patterns, declining soil quality, and a growing toxic burden have made it increasingly difficult to obtain adequate nutrients from our daily food intake. Bio-Avail Multi is designed to address these challenges by providing a comprehensive blend of essential vitamins, minerals, and phytonutrients that closely resemble those found in an ancestral, whole-foods diet.

Harness Years of In-Clinic Experience and Ancestral Wisdom

Backed by Adapt Naturals' 15 years of in-clinic experience and dedicated to creating supplements that make a meaningful difference, Bio-Avail Multi combines cutting-edge research with insights from ancestral wisdom to bring you a premium-quality supplement.

Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

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.

Yes, all Adapt Naturals products, including Bio-Avail Multi, undergo rigorous third-party testing for purity and potency. Most importantly, we transparently share these results with our customers by posting Certificates of Analysis (CoAs) and test results on our website. This level of openness is almost unheard of in the supplement industry. It allows you to see exactly what’s in the product you’re putting into your body. Click here to view the most recent CoA and test results.

Great Multivitamin

I especially like the blend and I even like the fact that I can see different colors within the capsule rather than a super-blend of overly ground up content that I see in other vitamins.
