I am a Nutritional Therapist and have been on Iodine therapy (25mg/day) for five months and kept failing the Iodine patch test which indicated I was still deficient. After reading Dr. Brownstein's book on Iodine and attending his seminar, I tried ATP Cofactors with the hope that this would be the missing piece in my low Thyroid function, low energy and FMS symptoms. After five days, I have lost five pounds, lost water weight and puffiness and have great energy!! I am so grateful for this product. It is amazing.
