In this personal testimonial, Vanessa Van Edwards describes how chronic fatigue and brain fog led her to seek comprehensive blood testing through Function Health after an email from Dr. Mark Hyman. The tests revealed a severe copper deficiency, which the clinician notes linked to excessive zinc supplementation from her immunity supplements while traveling. By stopping the high‑dose zinc, her symptoms resolved quickly, marking a "life‑changing" moment. Impressed by the speed, affordability, and breadth of the testing, she purchased the service for her husband and father, and now promotes a partnership with a discount/referral code. Vanessa emphasizes the interconnectedness of social, biological, and mental health, urging viewers to become their healthiest selves.

This is a really personal story, but early last year, I was so, so tired. I was sleeping 10 hours a night and sometimes needing a nap or 2 a day. I just felt brain fog and fatigue, and I did not know what was wrong. I didn't even know what to test. At that time, I got an email from Dr. Mark Hyman about his company Function Health, which was a way to test over 100 tests through blood work, metabolism, thyroid, immunity, Hormones, anything that could be going on. So I signed up. It was super easy. Within a couple of days, I was getting blood work at my local lab. I was super low in copper. First of all, I never would have known to test copper. So I see that it's super out of range, and I look in the clinician notes because when you do your blood work, they give you all these clinician notes, and it says possible causes of this is over-supplementing with zinc. Because I travel so much, I take a whole immunity A bunch of immunity supplements. And that was— I was taking so much zinc as I was on the road and I was in speaking tour and shaking 100 hands. Because I was over-supplementing zinc, it was causing me to have low copper and it was causing this terrible exhaustion and fatigue. It was very easy to fix. I immediately stopped taking that much zinc and the problem fixed. This was a life-changing moment for me because very affordably and very quickly able to test this and get a snapshot and then figure out exactly what was going wrong. And I am so grateful because there were so many other things in my labs that I was able to See, very quickly, I bought it for my husband. I made him immediately go take it. I bought it for my dad so he could immediately go take it. They're my new partner. I have a discount and referral code for you. I just wanna make this so clear. I have been paying for this myself for over a year. I bought it for my loved ones. I am so passionate about this that I wanted to share it no matter what. But the fact that they were willing to support me and be a partner is incredible. I think our social health, our biological health, our mental health, all of it is tied together. And so I want you to be your healthiest self in every way, and I hope that you'll love it.
