Learn What Bio-Avail Multi Can Do For You

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.

All Adapt Naturals 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!

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.
