What makes Bio-Avail Organ stand out?

Why make Bio-Avail Organ part of your daily routine?

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.

Feeling great!

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!

Excellent product

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!

My first time purchasing.

I really like the bottles they come in. The capsules are very easy to swallow. As I am just starting to take these I cannot say exactly what help they have been yet but I do feel as though I am starting to feel a little less tired throughout the day. I also have been using my inhaler far less which I am very happy about. I am also taking your multi vitamin and the mushrooms. I am sure they are working together to be helpful. I am looking for them to help make up for some of the lack of certain things in my diet as I also am starting to move my diet back toward the paleo/keto I was doing in the past very successfully. I am working on getting back on track as I felt so great when I was doing it before and I am getting older now.

Hello Kevin! So glad to hear that you have noticed a shift in your energy levels and that you have been able to use your inhaler less after adding Adapt Naturals into your routine. We hope that you continue to experience additional benefits in the future and we thank you for your kind review!
