Introducing the first
Multivitamin + Greens & Reds Powder—All in One Bottle!
We created Bio-Avail Multi to make it easy for you to get the full spectrum of nutrients you need to thrive, from vitamins and minerals like B12, vitamin D, and magnesium to phytonutrients like polyphenols, bioflavonoids, and carotenoids.
Unlike most multivitamins, which only provide vitamins and minerals, Bio-Avail Multi includes essential vitamins and minerals and a full range of research-based phytonutrients like lutein, lycopene, broccoli seed extract, and more.
It’s like taking a multi, greens, and reds powder in one supplement!
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 for optimal 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.

About Your Free Vitamin D3/K2
Vitamins D3 and K2 are critical for bone, heart, metabolic and immune health. Sadly, most Americans don’t get enough of these essential vitamins. While Bio-Avail Multi does contain both vitamin D3 (2,000 IU) and vitamin K2 (50 mcg), some individuals may need more of each nutrient for optimal health.
Bio-Avail D3/K2 contains 1,000 IU of vitamin D3 and 120 mcg of vitamin K2 per serving in a concentrated, liquid form. This makes it easy to reach your target daily intake. A single bottle of Bio-Avail D3/K2 contains 600 servings—up to a one-year supply of these essential vitamins!
Get a FREE bottle of Vitamin D3/K2 when you purchase Bio-Avail Multi today! When you purchase 6 bottles, you will receive TWO free bottles of Vitamin D3/K2.

Frequently Asked Questions
? What are the ingredients in Bio-Avail Multi?
? What do you think of the reports on the news that multivitamins don’t work?
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!
? How many bottles should I order?
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.
? How long will it take to get results?
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.
? Why would I need Bio-Avail D3/K2 when Bio-Avail Multi already contains those nutrients?
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.
? How much does shipping cost?
The cost of shipping for 1 bottle is $7.99. Shipping is free for orders of 3 or more bottles.
? When will I receive my order?
We ship most orders within one business day. Most orders take 2-3 days to arrive once shipped.
? Where is Bio-Avail Multi manufactured?
Bio-Avail Multi is manufactured in a U.S. facility that meets the NSF’s rigorous GMP (Good Manufacturing Practices) regulatory standards.
? What is the recommended way to take Bio-Avail Multi?
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.
? Is this a one-time purchase or auto-ship?
We offer both options. If you’d like to place a one-time order, choose the “one-time purchase” option (which is selected by default) above the “add to cart” button. If you’d like to sign up for autoship and save an additional 5%, choose the “Subscribe & Save” option.
? What if Bio-Avail Multi doesn’t work for me?
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.
