“I’ve been taking the Bio-Avail Organ for a little over a month now and it’s terrific. I’m feeling more energetic and also at ease that I’m getting more essential micronutrients than I was before.”
—Kelly W. -
“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.”
—Jenny D. -
“I've been taking the Bio-Avail Multi, Organ and Myco blends for 60 days now and feel healthy, strong, and like any vitamin/nutrient gaps in my diet are greatly reduced. Glad to have a product from a source I trust! Thanks much.”
—Kelly K.

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.
Add back in what the modern world has squeezed out.
Organ meats were a staple of most traditional diets—and are still regularly consumed in many parts of the world today.
Sadly, they’ve fallen out of favor in our modern diets, and most of us find the taste and texture of organ meats off-putting.
Bio-Avail Organ allows you to get the incredible health benefits of organ meats without having to prepare and consume them yourself.
Get the full spectrum of nutrients available from organ meats.
Most organ meat supplements on the market only contain liver and one or two other organs.
But studies have shown that heart, kidney, spleen, and pancreas have distinct nutrient profiles that complement liver.
Bio-Avail Organ contains a blend of all five of these nutrient-dense organs, so you can enjoy the full benefits of these remarkable nutrient powerhouses!

See Test ResultsThere are so many supplements that we take that we don't necessarily feel "working". The Bio-Avail Organ is not one of those! It gives me obvious more energy on a daily basis, not something I have to try to observe. I even tried a different brand of organ supplement and it did not have the same benefits. As I fine tune my stack, this is one supplement that will be a core one. I even have my 18 year old son taking them now to give him extra support.
Hey Mary,
Obvious daily energy that you do not have to look for or try to observe and noticing the difference when you switched to another brand and came back...that is the 100% grass-fed liver heart kidney pancreas and spleen delivering CoQ10 heme iron B vitamins and amino acids in a form the body genuinely recognizes and uses rather than just passing through. And now your 18 year old son is on it too which is such a wonderful thing! We are so glad it has become a core non-negotiable in your stack and thank you so much for sharing!
Finding food-based ways to support my low iron, in a way that also supports important co-factors to help my body utilize iron better! I trust the quality which matters to me most.
Hey Grace,
Finding food-based iron support that also delivers the co-factors the body needs to actually absorb and use it is such a smart and informed approach and we are so glad Bio-Avail Organ is ticking that box! The heme iron in grass-fed liver is some of the most bioavailable available and the full organ complex brings B vitamins copper and other co-factors that work alongside it exactly the way you are thinking. Quality matters and we take that seriously every step of the way. Thank you so much for sharing!
This product is a great addition to my varied diet. I appreciate that it is available for me to use. Thank you1
Hey Elizabeth,
A great addition to a varied diet and we are so glad it is earning its place! The 100% grass-fed liver heart kidney pancreas and spleen in Bio-Avail Organ bring a dense concentration of CoQ10 heme iron B vitamins and amino acids that are genuinely hard to get consistently from diet alone and we are honored to be part of your routine. Thank you so much for sharing!
Since taking these supplements, I have noticed less inflammation in my body overall, my joints feel better, and they have helped with brain fog. I highly recommend these supplements to anyone struggling with this.
Hey Kristie,
Less overall systemic tension better feeling joints and clearer thinking from organ supplements is such a meaningful combination of outcomes and speaks to just how nutrient dense the 100% grass-fed liver heart kidney pancreas and spleen in Bio-Avail Organ really are. The CoQ10 from heart the B vitamins and heme iron from liver and the full amino acid and micronutrient profile across all five organs working together every day creates that kind of broad whole body response. Thank you so much for the recommendation and for sharing!
Great products, excellent service
Hey Valerie,
Feeling pretty good across the whole stack after a few months and trusting the combination even when it is hard to isolate which product is doing what is such a smart and honest way to approach it. The synergy of multiple products working together is often greater than any single one and the fact that you feel good overall is the whole point. Great products great service and a loyal customer and we are so grateful for all three. Thank you so much for sharing!
Your Questions Answered
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!
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:
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!
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.
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.
The cost of shipping for 1-2 bottles is $6.99. Shipping is free for orders of 3 or more bottles.
Allow 1-2 days for order processing and 4-7 days for shipping, excluding weekends
Bio-Avail Organ is manufactured in a U.S. facility that meets the NSF’s rigorous GMP (Good Manufacturing Practices) regulatory standards.
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!
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.
