Lol, yes you do. I have some sympathy though, because I react poorly to at least 90% of common vitamins and supplements. I'm always amazed that people can take standard mega-dose multivitamins and feel well on them. There are multiple ingredients in there that individually will ruin my well-being (niacinamide, C, B1, B2, B6, A, D, high dose E, and zinc are among the worst offenders).
You have a couple things going on that interact to produce disastrous results. The first is the aforementioned exceptional sensitivity to supplements. The second: your ability to discern health-related cause and effect relationships accurately is quite poor. No one is as good at this as we'd like to be, including myself (many notable failures here in my past), however, you are more challenged in this respect than most.
My suggestion then would be to default towards the most minimalistic approach to supplementation and medication possible. Really, this is a good idea for everyone, but it becomes essential when a delicate constitution is mixed with a confused sense of causality.
For example, I was biting my tongue watching the iron supplementation in the context of a male on a carnivore diet. Unless you have chronic internal GI bleeding, it would have been virtually impossible for you to be truly iron deficient, regardless of ferritin level (not always a perfect indicator of iron status).
So if I were your health coach, my advice to you would be to continue with an animal-based diet, take your jatenzo, and that's it. Consider anything beyond that with extreme caution and observe effects closely, changing only a single variable for extended lengths of time.
