Review: Great Product - I am taking iodine and Optimox ATP is recommended to take with it.
Review: Must have if you're on Idoral... - I've been on Idoral since December 2012. At that time I had an ultrasound on my thyroid, did blood work and felt like crap. I read Dr. Brownstein's book on iodine and decided to give it a try. I started feeling better right away, but there seemed to be something missing... so I read the book again and realized I'd left out the ATP Cofactor. Immediately ordered it, and after 1 week felt that "something missing" slip away... and I felt great!!! Moved my mother to Florida in May, and accidently left my bottle of ATP Cofactor at her place. Didn't really think much about it for about 3 weeks... then it started again... the tired achey feeling, needing a nap right after work. Oh man... What did I forget? Then I realized AGAIN that I was forgetting the ATP Cofactor. Immediately ordered TWO bottles, one as a back up... Yesterday, (June 11th, 2013) I went to my endo for a 6 mos follow up and ultrasound on my thyroid. Not only did the small nodule on the right side DISAPPEAR, but the larger nodule on the left side was 4mm smaller than it was back in December. Also, my overall thyroid (goiter) was smaller. I've learned that if I take this stuff as Dr. Brownstein says (including selenium) I feel GREAT!! Energy levels that make me feel good enough to actually exercise mildly, clearer head, and no more choking sensation from a swollen thyroid (goiter). The surprising benefit was I lost 6 pounds without trying... that's one pound a month without struggle and emotional turmoil. The only other thing I did was get my hormones balanced. I was diagnosed as estrogen dominant in March. All I take for that is 100 mg natural Progesterone for 14 days a month. My recommendation on this page is that you ADD in the ATP Cofactor if you're doing iodine therapy. It REALLY does make all the difference in the world.
