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.

Gut issues

In just a few short weeks, i have noticed my stomach feels like it is settling with the bloating and gas. Taking in the AM with a glass of water takes the gas and bloating away for the whole day.

Hi Lois. We are thrilled to hear you have noticed improvements in your gut health. Thank you for trying our Bio-Avail Organ and sharing your experience. All the best!

High Quality

I received a free package of Bio-Avail Organ with my first purchase of the Bio-Avail Multi. I’ve been taking the Bio-Avail Organ for only a couple of weeks, but I can already tell that the product is of much higher quality than other organ supplements that I’ve previously tried. I like that this supplement contains many forms of organs—not just liver—for a higher nutritional value. I’m excited to continue taking this product for improved energy and nutritional support.

Hi HR, We hope you will experience all the benefits of our Bio-Avail Organ and Multi. Thank you for your continued support and for leaving us a review!
