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.

So far so good

Been taking for about a month now. It’s good to simplify life as well as my supplement regime as it gets extensive at times. I trust Adapt and been taking the Organ and Multi.

RLS improved

I took the multi, myco, and organ bundle for brain fog and long covid. I noticed great improvements in the fog and restless leg symptoms improved as well. Based on supplements I was previously taking- lots of B’s, magnesium and other minerals- I suspect the organ situation here is what helped with the RLS. Whatever it was in the bundle, I definitely don’t get enough organ meat in my life. If only pate wasn't so high calorie!

In past I took bovine desiccated liver supplement and it had horrible aftertaste.

No aftertaste or digestion issues at all with any of the bundle even with minimal food.
Thanks Chris!

Hi Karen, we are so happy to hear that Bio-Avail Multi/Myco/Organ have helped improve your brain fog and RLS symptoms, and that Bio-Avail Organ has no aftertaste. Thanks for taking the time to leave a review!
