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 New Zealand cattle. Taking this nutrient-dense supplement daily is equivalent to eating about 4 ounces of organ meat a week.
Bio-Avail Organ highlights:
✔ Equivalent to eating about 4 ounces of nutrient-dense organ meat a week—exactly in line with what most experts recommend
✔ Sourced from 100% grass-fed, grass-finished, free-range New Zealand cattle
✔ Comes from animals that are never given antibiotics, growth hormones, or stimulants
✔ No artificial or synthetic ingredients and no artificial flavors, colors, or chemical preservatives
When it comes to nutrient density, edible offal and organs win hands-down. A single serving of liver meets the Recommended Dietary Allowance (RDA) for vitamin B12 for an entire week and far exceeds the daily RDA for vitamins A and B2 (riboflavin) and copper. While most of us don’t include organ meat in regular rotation, Bio-Avail Organ has you covered with a blend of five freeze-dried bovine organs—liver, heart, kidney, pancreas, and spleen—sourced from 100% grass-fed, grass-finished, free-range New Zealand cattle.
Bio-Avail Organ contains 1 gram of liver, the most commonly consumed organ. But it also contains 500 mg each of heart, pancreas, kidney, and spleen. These organs have unique nutritional value and complement the nutrient profile of the liver, ensuring that you get the full benefits of “nose-to-tail” eating and the full range of nutrients and amino acids, which we don’t get when we consume only muscle meats (like steak, for instance).
Bio-Avail Organ is sourced from 100% grass-fed and grass-finished New Zealand cattle (free from bovine spongiform encephalopathy). These cattle are never given antibiotics, growth hormones, or stimulants, and they come from one of the cleanest environments in the world.
The current Western-style diet has shifted away from ancestral diet patterns toward energy-dense, ultra-processed foods that are low in the essential micronutrients required to maintain healthy tissues and organ functions. Bio-Avail Organ is rich in nutrients—like retinol (the active form of vitamin A), iron, vitamin B12, vitamin B6, folate, and choline—that modern diets fall short in.
Our ancestors were nose-to-tail eaters, meaning they consumed all parts of the animal—including skin, cartilage, bone marrow, animal fats, tendons, muscle, and organ meats, which helped provide a wider range of nutrients. Many people following Paleo, primal, carnivore, or similar diets know this but have difficulty preparing and eating fresh organ meats. A daily serving of Bio-Avail Organ provides the equivalent of eating 4 ounces of fresh/raw organ meats a week, which is in line with what most nutrition experts recommend.
A recent study found that organ meats like liver, spleen, kidney, and heart comprised four of the top seven most nutrient-dense foods that we can eat when it comes to essential nutrients like iron, zinc, folate, vitamin A, calcium, and vitamin B12. What’s more, the nutrients in organ meats are in a highly bioavailable form that is easy for the body to digest and use.
The nutrients in Bio-Avail Organ play critical roles in cellular energy production, DNA synthesis, and oxygen deliverability, among many other functions. This likely explains why doctors in the early 20th century referred to liver and other organs as “anti-fatigue” factors. Bio-Avail Organ contains nutrients that can help boost your energy and increase your vitality. And because of the role they play in sleep, these nutrients can promote better rest and a better mood.
Organ meats are rich in nutrients that support performance and recovery, including protein, coenzyme Q10, L-carnitine, L-carnosine, creatine, taurine, vitamin B12, and iron. Athletes in many countries around the world consume organ meats to give themselves an additional competitive edge.
Suboptimal intakes of essential micronutrients contribute to poor health and reduced longevity. Taking Bio-Avail Organ each day builds resilience and supports the optimal function of all organs, tissues, and systems in the body—including key nutrients that aid in the body’s natural detoxification process, all of which may contribute to greater health and a longer lifespan.
Bio-Avail Organ is best taken with food. We recommend taking three capsules in the morning with breakfast and three capsules in the evening with dinner. Bio-Avail Organ can also be added to food if you wish to reduce the number of capsules you take daily. We suggest opening up the capsule and adding the contents to seasoned ground meat dishes (e.g., taco beef, meatloaf) as you cook if you don’t enjoy the flavor of organ meats.
A popular objection to eating liver is the belief that it is a storage organ for toxins in the body. While it is true that one of the liver’s roles is to neutralize toxins (such as drugs, chemical agents, and poisons), it does not store these toxins. Toxins the body cannot eliminate are likely to accumulate in the body’s fatty tissues and nervous systems.
On the other hand, the liver is a storage organ for many important nutrients, such as vitamins A, D, E, K, B9 (folate), and B12, and minerals such as copper and iron. These nutrients provide the body with some of the tools it needs to get rid of toxins. This means that consuming liver is more likely to help the body with detoxification than cause any accumulation of toxins.
I do not mind the taste of organ meat but have difficulty finding high quality meats in my area. Bio-Avail Organ solves this problem. It has no taste and is easy to swallow. Thank you Chris Kresser for your high quality products!
It’s sooh difficult and expensive to find safe organ meet these days that I was relieved to learn about Adapt Naturals organ blend. I subscribed promptly.
I started taking Bio-Avail Organ at the same time as the Multi and the Myco. At first I wasn’t taking it as directed, I was taking a little less. Once I started taking these supplements as directed, I noticed an immediate improvement in my energy and cravings for junk food. I had more energy and it was easier to avoid foods that aren’t as nutritious. I am sure it is filling a lot of nutritional gaps. I also trust Chris Kresser to create a quality product.

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.
Hi Kelly, we're thrilled to hear of the noticeable difference in your energy after taking the Bio-Avail Organ. We appreciate your review!
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.
Hi Jenny, It's a pleasure hearing from you how excellent the Bio-Avail Organ supplement is. We hope you continue to benefit from it. Thanks for leaving us a review!
