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.

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.

Feeling strong

I’m really loving how I feel after I take these, I have more energy and stamina. I did adjust how much I take because I was having some hormonal acne when taking the suggested dose but it went away when I lowered it

Hi Veronica, We are thrilled to know you are getting the energy and stamina you need to perform your daily duties. Thank you for sharing your experience with our Bio-Avail Organ. All the best!

Elizabeth Root
Worth it

I have struggled with trying to eat enough clean organ meats plus juggle my job as a homeschooling mom. My ferritin continued to be low despite a year of eating organ meats. I decided to give this a try and I do have more energy and am confident in the quality of this supplement.

Hi Elizabeth, We are happy you gave our Bio-Avail Organ a try and it is working well for you. Thank you for being an Adapt Naturals customer. We appreciate your review!

Acacia Rogers
So much more energy and less "Womanly" symptoms

So I am someone with a lot of food sensitivities, hormone, and energy issues. Im always trying to find supplements to help. Bio Avail Organ is for sure a permanent addition to my nutritional regimen now. Im so glad this sort of thing exists because ive never seen something like it before. These were nutritional gaps that needed filling.
It not only helps me look and feel more alive, and sleep better, but also has the pleasant side effect of helping with mentrual symptoms. Which is excellent because I was prone to bad migraines, which are much more mild now. I just hope I can keep affording it.

Hi Acacia, Thank you for reviewing our Bio-Avail Organ. We are so happy your sleep has improved and you feel much better since trying this supplement. Thank you for supporting Adapt Naturals. Best of Health!
