Selenium is a natural element found in low amounts in the Earth’s crust. Somehow, deficiency is not common among healthy people. Deficiency does seem common among people with compromised immune systems and issues that go along with that, which includes auto-immune, IBS, allergies, etc. Selenium deficiency is commonly found when people have HIV, Crohn’s disease, Grave’s disease and Hashimoto’s disease. Overdose can be common when people have gene mutation expressions such as MTHFR due to the body not being able to physically process the selenium as part of an important detox phase.

Selenium and iodine

Taking iodine allows our body to carry out processes it may not have been able to before. As these ‘new’ processes start happening, our body is most likely going to need some other fancy stuff to keep up with all the awesomeness. Selenium plays a key role in our metabolism, which is a pretty important process. Iodine can actually make some what of a mess of our metabolism when we start taking it, due to our body doing things it isn’t used to being able to carry out for a while. This is why selenium is important to have on hand while taking iodine. Iodine is capable of helping our body chelate mercury and other potent toxins. If mercury is flowing around our body, and we don’t have enough selenium on hand, the mercury is capable of setting off miniature bombs in our brain, which we then feel in the form of inflammation.

How do I know if I am deficient in selenium?

Without some type of testing, usually a selenium serum test, it is pretty hard to say. I assume I am not low on it mainly because I do not have any autoimmune type conditions and consider myself somewhat healthy other than being loaded with the average toxins and parasites. I also add selenium and other nutrients to my garden and eat tons of dark leafy green stuff. I made it about half way into winter without supplementing any selenium, but I was only taking iodine sporadically and still had access to kale from my greenhouse. I started to notice a somewhat familiar feeling where I almost feel lightheaded but not really and I get a tunnel vision type of feeling. It’s hard to explain but I essentially get pretty light headed randomly and it almost makes me wonder if I am about to pass out for a split second but never to the point I’m scared of what the heck is going on. It dawned on me to try selenium and I’m almost positive there was a direct connection in taking it and that feeling going away.


This stuff is pretty important, be careful

Going too low most likely starts causing autoimmune type conditions. Going to high gets into weird stuff like hair loss and impaired motor control. Although most people are not deficient of selenium, it’s hard to know where we are on this spectrum. The upper daily recommended is 400mcg per day but I take 200mcg and don’t take it daily. I like to pay attention to how I feel when I take these supplements, so sometimes I’ll take more than recommended, to see if it makes me feel any better, and then I’ll pretty much stop taking it to see if I notice any old symptoms creep up. Over time, I’ll forget to take a supplement for a while and eventually start noticing a symptom, so I take the supplement and now have a better idea how much of it my body needs.


Some signs of selenium toxicity to watch out for


Technical info:


It is recommended to take about 200-400mcg per day while taking iodine.


I noticed something very interesting with Selenium

A few years into my healing process with the iodine protocol, I happened to be at a very stressful job that was causing me to drink beer again. I was drinking about 4 beers a day, sometimes more, sometimes less. But I started noticing that I was feeling hungover at work and just wanted to put my head down most of the day, so I cut back on beer and noticed just my 2 beers was making me feel very poorly the next day. Then one day I realized it seemed like my familiar selenium deficiency feeling, and took a co-worker’s 200mcg selenium and instantly felt amazing. About 15 minutes later my stomach started yelling at me and I had to make an odd poo out of no where, which to me means I just process some kinda toxin.

I decided to experiment with this and kept taking 200-600mcg of selenium each day and within a few days I drank 8 beers a few nights in a row and wasn’t getting the slightest bit of hang over feeling. After about 2 weeks, I started to notice a feeling catch up with me again and noticed I wasn’t keeping up on my magnesium, as I took more magnesium, I was actually feeling more hangover feeling the next day, but noticed I seemed to be processing some type of toxin. After doing this for a while, I felt like I had just cleaned out some old type of funk, possibly even funk from the beer I’ve drank in the past.

This is another example of how detox most likely works in our body. Once we get enough of the right nutrients, as our body is in the right condition, we poo out bad stuff and feel better. I went over how sulfur and zinc made me go through an awesome detox phase in Low and Slow.

INNATE Response Whole Food Selenium

Some people have a sensitivity to foods and supplements that contain yeast. I am almost positive this brand selenium is Not made with yeast and is one of the best options to start with, but I could be mistaken, please research further if avoiding yeast sounds important to you. This ends up being very expensive in the long run but I think it is important for at least the first month or so. We are not able to absorb things well if our gut is in bad shape, Selenium is important, so having a quality one would be better till we get in better shape.

Selenium can be made with yeast which is potentially dangerous for some people.
