Worked for my friend, but not for me - tannins
on January 11, 2016
This review is more about a side effect I experienced while taking this supplement more than the efficacy of the supplement. My friend has been taking this supplement as instructed for a year and has noticeably improved her thyroid symptoms, numbers, and overall thyroid health. I started taking it a couple of weeks ago in an attempt to improve my hypothyroid symptoms (frequent periods, cold hands and feet, fatigue, inability to shed excess weight, family history, etc.) Shortly after taking the supplement, I experienced one of the WORST headaches I've ever had. It wasn't a migraine, but it was as close to one as I have been in years. I figured it was probably a cold, but I had no other cold-like symptoms, and the headache has not fully gone away since then (though now it is just a dull ache). This is the only supplement that I have changed in the previous couple of weeks, so I looked into the ingredients. Come to find out, black walnut hull is very high in tannins, the same things in red wine that occasionally give people headaches when they drink it (such as my mother and I who both have hypo and experience headaches with tannins). I'm not 100% sure that this is the ingredient that is causing my headaches, but I know myself well enough to know that this is the most likely cause of the headaches since they didn't start until about 2 weeks ago and I haven't changed anything else in my diet, supplements, or lifestyle.
If tannins do not cause you a problem, I encourage you to try this supplement if you are experiencing hypothyroidism symptoms, as my friend had great results. If you get headaches when you drink red wine or are reactive to any of the ingredients, try another thyroid supplement.
