I feel amazing!

I have Graves Disease and my endocrinologist suggested I start taking Selenium to support my thyroid, and my eye discomfort, which is a side effect of Graves. I was taking an over-the-counter supplement and my eye discomfort was getting worse and worse and the store brand wasn’t helping at all. I looked at the “Other Ingredients” and I found “extras” that I didn’t feel were necessary. I started searching for a pure selenium supplement that could help. I found Thorne’s and I have felt absolutely amazing! Thank you!!

Excellent Mineral

You will not be disappointed. Selenium will help recovery quickly if you are into sports such as soccer. When traveling abroad to Taiwan or Korea and having hiked some of their trails, selenium is always in my travel luggage. You will have a quick recovery time so you can enjoy more of your trip.

Taking for Thyroid

My doctor suggested I take selenium with iodine and zinc. So I have been taking this for 2 months. I'm not sure if it's really working. I don't have as much fatigue as I used to have, and I also dropped so much weight my bottoms are all stretched, I can ball up a handful of that's a good thing. But my period is wonky, its been getting later and later, and the only time this ever happened was when I was really iodine deficient. So I don't know. I will update this review in 3 months.

It Works!

I've used this for almost a year now to go with my iodine supplementation for estrogen dominance. I wasn't thrilled on having to take more capsule but it seems worth it to me now.
