As someone who had a total thyroidectomy, my energy levels are not what they used to be before my surgery. I found it challenging to do even basic household chores, which would leave me unreasonably winded. SuperEnergy helped with that issue; I am not collapsing on the nearest sofa when I climb up the stairs anymore. But while I am happy with the results, they aren't immediate. I feel like my body had to get used to the product for a few days first.
