Get Those Essential Nutrients
“The BioAvail Organ supplement is excellent. I have always been hesitant to take an organ complex because I was concerned about the amount to take in comparison to the proper amount of organ meat to eat in a week. I know that the amount I am taking in this supplement is the correct amount for optimal health because it contains the same amount of organ meat Chris Kresser recommends a person eat in a week. Thank you for creating this product.”

The Easiest Way To Tap Into an Energy Powerhouse!
Organ meats are among the most nutrient-dense foods we can eat.
A single serving of liver meets the RDA for vitamin B12 for an entire week and far exceeds the daily RDA for vitamins A and B2 (riboflavin) and copper!
Bio-Avail Organ contains a blend of five freeze-dried bovine organs—liver, heart, kidney, pancreas, and spleen—sourced from 100% grass-fed, grass-finished, free-range cattle.
With Bio-Avail Organ, you get the incredible health benefits of organ meats without having to prepare and eat them!
What makes Bio-Avail Organ stand out?
5-Organ Blend
Many organ supplements only contain liver and one or two other organs. Bio-Avail Organ features a blend of five organs so you get a full spectrum of essential vitamins and minerals.
Clean & Pure
Bio-Avail Organ is sourced from 100% grass-fed, grass-finished cattle that are never given antibiotics or hormones.
Nutrient-Dense
Taking Bio-Avail Organ daily is equivalent to eating 1–2 servings of organ meat a week, which is what most experts recommend for optimal nutrient intake.
Unlock all-day energy, superhuman performance, and vibrant health!
A recent study found that organ meats comprised four of the top seven most nutrient-dense foods we can eat.
Liver was 25x more nutrient-dense than beef and 35x more nutrient-dense than most vegetables!
This explains why traditional cultures around the world have prized organ meats for their ability to boost energy, improve libido and fertility, and slow the aging process.

Frequently Asked Questions
? What are the ingredients in Bio-Avail Organ?
? Will I taste the organ meats in this supplement?
We know that most people today can’t stand the taste or texture of organ meats—which is exactly why we made this supplement. You can get the benefits of eating organ meats without preparing or tasting them!
? What is the nutritional profile of organ meats?
A 2022 study published in the journal Frontiers of Nutrition found that organ meats comprised four of the seven most nutrient-dense foods we can eat—with liver at the top of the list. Organs are especially rich in B vitamins like folate and B12, minerals like iron, magnesium, selenium and zinc, fat-soluble vitamins like A, D, E and K, and other essential nutrients like choline that most people don’t get enough of.
Organ meats are truly “nature’s multivitamins.” A single serving of liver provides:
? How much should I take each day?
Taking the recommended dose of six capsules of Bio-Avail Organ each day is equivalent to eating one to two servings of fresh organ meats per week. This is exactly what our founder, Chris Kresser, and other health experts recommend. As you can see from the table above, organ meats are so potent and nutrient-dense that you don’t need to eat more than a couple of servings a week to benefit!
? 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 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 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 3 or more bottles.
? How long will it take to get results?
Most people see positive changes like more energy, deeper sleep, greater libido, 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 Organ at least three months before determining whether it is working for you.
? How much does shipping cost?
The cost of shipping for 1-2 bottles is $6.99. 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 Organ manufactured?
Bio-Avail Organ 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 Organ?
The recommended dose is six capsules per day taken with food. We suggest taking three capsules in the morning with breakfast and three 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. You may also take all six capsules at once, or two capsules three times a day, if you prefer. Since this is a whole-food supplement, you’re free to consume it however is most convenient for you!
? 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 Organ 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 Organ 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.
