Powerful Nutrients & Vitamins



Often called “nature’s multivitamin”, liver contains a variety of vitamins and minerals, including vitamins A, E, B1, B3, B6, biotin, and folate, along with copper, heme iron, zinc, and omega-3 fatty acids.



Heart is one of the highest dietary sources of CoQ10, which is a critical antioxidant that protects our cardiovascular system and plays an important role in cellular energy production. 



After liver and clams, kidney is the highest dietary source of vitamin B12–with a single serving providing 1118% of the RDA! Kidney is also a good source of the rare amino acid L-Ergothioneine, which supports detoxification and longevity pathways.



Pancreas is a rich source of B12, vitamin B12, and vitamin B5. The pancreas secretes digestive enzymes and produces hormones that regulate blood sugar.



Spleen is perhaps best known for being an incredibly rich source of bioavailable iron. This is crucial because iron deficiency is still common today, even in the industrialized world.

Why Choose Bio-Avail Organ?

Our modern diets often fall short of providing the optimal amounts of essential nutrients our bodies need to function at their best. With Bio-Avail Organ, you can overcome nutrient deficiency and support your overall health and well-being. We've done the research, so you don't have to!

Bio-Avail Organ is sourced from 100% pasture-raised cows in Argentina never given antibiotics, hormones, or GMOs.

Formulated to Replicate Optimal Ancestral Diets

Changes in dietary patterns, declining soil quality, and a growing toxic burden have made it increasingly difficult to obtain adequate nutrients from our daily food intake. Bio-Avail Organ is designed to address these challenges by providing a food-based source of essential vitamins, minerals, amino acids, and other compounds that close the modern nutrient gap.

Harness Years of In-Clinic Experience and Ancestral Wisdom

Backed by Adapt Naturals' 15 years of in-clinic experience and dedicated to creating supplements that make a meaningful difference, Bio-Avail Omega+ combines cutting-edge research with insights from ancestral wisdom to bring you a premium-quality supplement.

Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

Your Questions Answered

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.

They are sourced from 100% pasture-raised cows in Argentina never given antibiotics, hormones, or GMOs.

feeling great

I started taking several of these supplements (metabolic support stack, plus organ) at the same time, so it's difficult to say which has been the most effective and necessary, but I feel great. I went from having a lot of problems with feeling hungry, and hangry, all the time, to having much more control over what I eat and how much I eat. I am eating much less but without any loss of energy or feelings of frustration and hunger. It's really been life-changing for me.

Solar, so good!

So far, so good! I am ordering again because I feel like it is helping me. I have trouble getting a balanced diet when I am busy directing a summer camp and vacationing with grandchildren. I do take a multivitamin but the addition of the Bio-available organ is giving me more energy.

Batoul Baterdouk
Excellent product

It gives me the energy I need

Hi Batoul, We are glad too hear our Bio-Avail Organ is providing you with the energy you need to function on a daily basis. Thank you for your review!


A great supplement as someone who doesn't like the taste of organ meats. I love the pasture raised grass-fes sourcing and my energy levels are much better when I take it.

Hi karl, Thank you for sharing your experience with our Bio-Avail Organ. We are happy you are loving this supplement. Best of health!
