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.
