Powerful Nutrients & Vitamins

Liver

Liver

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

Heart

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. 

Kidney

Kidney

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

Pancreas

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

Spleen

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.

a much better way to raise iron levels

I love this supplement. Keeps my iron up (I'm anemic) without some of the more dangerous and/or uncomfortable side effects of traditional iron supplements. My iron levels are back on track after starting this supplement regimen!

Hi Cory,

We’re so glad Bio-Avail Organ is helping you feel your best! Organ meats like liver and spleen are some of nature’s most powerful sources of highly bioavailable iron—and without the digestive upset that often comes with synthetic iron supplements. Thanks for sharing your success story!

so good for you!

I know the benefits or consuming organ meat on a regular basis but I've struggled with cooking it and making it part of my diet. Thank you Adapt Naturals for solving this problem with your supplement!

Hi Jill,

Thanks for your kind words! We created Bio-Avail Organ precisely for people like you who understand the value of organ meats but prefer a more convenient format. So glad it’s made a difference in your routine!

Stamina Booster !

I have been taking Bio-Avail Organ for several months now and the difference is distinct ! I recommend this one to anyone looking to boost stamina and feel supported in the ongoing stressors of daily life.

Hi Erik,

We love hearing this! Bio-Avail Organ is packed with some of nature’s most nutrient-dense foods, and it’s great to know you’re feeling the difference. Organ meats provide essential vitamins, minerals, and cofactors that help fuel energy, resilience, and overall well-being—especially in the face of daily stressors.

Thank you for sharing your experience and for recommending it to others! We appreciate you being part of the Adapt Naturals community and look forward to continuing to support your health.

Less equals more

I was able to eliminate four different supplements from my routine by taking this one. The health benefits and cost savings make this too good of a supplement to pass up.

Hi Joy,

Thanks for this feedback about Bio-Avail Organ! It's great to hear that you're seeing both health benefits and cost savings. You've hit on exactly why we formulated this product - with over 4 grams of nutrient-dense organs per serving, it provides comprehensive nutrition that would normally require multiple supplements. The combination of grass-fed liver, heart, kidney, pancreas, and spleen delivers nature's most potent nutrient blend in a convenient form, without having to source and prepare organ meats yourself.

Thanks for being part of the Adapt Naturals community!

Wow! Energy booster

I've been taking only two per day and I definitely have noticed a difference in my mood and overall energy levels. Does anyone else take less than the recommended dosage? I'm thinking of doing two twice per day starting next week but will that make a difference if I'm already noticing the benefits? Anyway, these are for sure worth a try.

Hi Gina :) We’re thrilled to hear you’re loving Bio-Avail Organ! While most individuals follow the recommended dose of 6 capsules per day, others have a positive response with a decreased dose. Our founder and chief formulator, Chris Kresser, has done quite a bit of research to determine the optimal dosage for all of our products, but that does not mean a smaller dose is not effective. Individual responses to supplements can vary quite a bit from person to person, and it’s really up to you to make the determination for yourself. It often boils down to simple trial and error to see what feels best for you. We hope this helps! Please take good care.
