Introducing Chris Masterjohn Lite

Zinc is needed for healthy skin, a robust immune system, sharp vision, stable blood sugar control, balanced and strong hormonal health, and far more. It’s even needed for protection against the heavy metals that pollute our environment.

Here’s how to make sure you’re getting enough — but not too much!  — from managing your diet, to non-dietary causes of deficiency, to measuring and managing your zinc status with bloodwork.

    1. The main interaction is that zinc stimulates metallothionein, which chelates copper. This can happen all throughout the body.

  1. I have been having difficulty eating. No appetite and stomach pain. I also have been experiencing acne as well. I am a 63 year old woman. My primary care physician has no time, knowledge or suggestion. I have an upcoming appointment with a new gastroenterologist. Upper endoscopy from 2015 and a month ago show no infection.
    I do take zinc along with my magnesium daily. I do have the MTHFR defect. I found this out four years ago. I am tired of trying to fix myself. The nausea is getting to me. I am bones from the weight loss.
    God help me.

  2. Hi Chris! Thank you for your thoughts here! This is of particular interest for me as I am an NTP and we use what is called the zinc taste test to determine zinc status in our clients. Are you aware of this test and if so what are your thoughts about its efficacy in relation to what you wrote here? Also, do you have any experience with zinc supplementation and a resulting nausea connected to copper dumping? Thanks in advance!

    1. I’ve never seen it validated, so I can’t comment on its validity. On principle, I suspect it somewhat correlates with zinc status but would be very inferior to looking at plasma zinc. It’s probably influenced by factors affecting how quickly ionic zinc migrates in the mouth, as well as taste receptor sensitivity, not just zinc status. Of course, you could do your own little validation study by comparing the results to plasma zinc readings.

    2. The nausea is not from “copper dumping.” It’s from using too high a dose of zinc on an empty stomach.

  3. My doctor tells me that I am deficient in both zinc and copper. I take Cu in pills (2mg one or two a day). If I don’t my skin tears easily. I added Zn (30mg BID) and have not had the levels retested but I am concerned because Zn and Cu seem to compete so I don’t know how to get enough of both while not getting overdoses.
    I wonder what the underlying cause is; I am supposed to have a hip replacement soon and believe it would help to have normal Zn and Cu levels in my body.

    1. Please see today’s video on how to supplement with zinc. Take the Cu with a meal and take the zinc as per today’s video.
