  1. Thank you for a great pod cast! And, I especially would like to thank you for including Canadian professionals. It is sometimes discouraging to hear a super podcast and at the end discover that products or services are only available in the US.
    I am quite interested in the offerings from DR Dempster program today, as well as where to purchase the liposomal gluthathione.

    Thanks again!

  2. Great podcast thank you! I wanted to find out if Dr. Dempster’s program involves any of the functional blood tests discussed in the podcast like the ogranic acids test?

      1. Thank you so much for your reply. I will check that out & if I decide to order the test would you go over my results once I receive them back?

          1. I would like to order organic acid tests for myself & my husband so would I just add 2 tests to the cart & checkout or do I need to do each one separately so you know who it was done for when you get the results from the lab sent to you.

          2. Can I ask what the cost is going to be for someone to go over the tests once the results are in?

          3. I am getting ready to purchase the organic acids test & my husband and I are wanting to also do some whole body cleansing and I assume it would be best to do the test first an wanted to find out your recommendation regarding this?

    1. I placed 2 orders today 1 for me Laurie & one for my husband Brian and I only received an email notification for order #37660 I believe the order for myself was #376659 but I did not receive any order confirmation & I did not see a phone # to call you guys to check on this. Also, I wanted to make sure that you are getting this OATS test done from Great Plains Lab like your site shows for the sample lab report & not some other lab. If you could please reply to confirm 2 orders one for Laurie Stanislawski &1 for Brian Stanislawski & that the lab will be great plains. Thanks

  3. Great podcast! New listener here. I’m 50 and am in pretty great shape. I’m a group fitness instructor and like you consider myself an athlete but not professional. I eat healthy and exercise daily (strength training and cardio). I’ve been looking for a list of functional tests to get done and heard many mentioned on this episode. Is there a way to get a copy of the list and what each test is for? Was hoping this info would have been in the show notes since it was discussed on the show.

    1. Hey Jai, welcome to our community. Yes here are some great functional tests we discussed in the interview and that we recommend.

      Comprehensive Blood Analysis: Our Comprehensive Blood Analysis (CBA) is very extensive and covers all the advanced markers needed to truly understand what is happening on a systems level in the body. This test will look at immune factors, blood cell factors, signs of leaky gut and low stomach acid, gallbladder health, vitamin D status, thyroid and inflammatory levels in the body and more.
      For more info on the Comp Blood Analysis go here https://drjockers.com/comprehensive-blood-analysis/

      Organic Acid Test: This will look at urinary biomarkers of B vitamin deficiencies, neurotransmitter deficiencies, microbial overgrowth, oxalate levels and mitochondrial dysfunctions.
      For more info on the Organic Acid Test go here https://drjockers.com/comprehensive-organic-acid-test/

      Advanced Food and Chemical Sensitivity Test
      Food and chemical sensitivity testing allows us to identify the immune provoking agents and eliminate them from our diet. This reduces inflammation in the body and quiets down the hyperactive immune system. When this is combined with proper gut healing and immune modulating nutrition and supplement protocols the gut is able to heal and seal. This is the most accurate test on the market for food and chemical sensitivities.

      GI MAP Stool Analysis: This Comprehensive Stool Analysis detects the presence of pathogenic microorganisms such as yeast, parasites and bacteria that contribute to chronic illness and neurological dysfunction. It also provides key information about the status of the gut and gut associated immune system.

  4. Dr. Jockers, You mentioned a link for a discount for the Healthy Gut Institue program on the podcast, but I don’t see it here. Is there one? Thanks.
