While I don't need thyroid supplements, I know that my past thyroid problem puts me at increased risk for developing hypothyroidism at some point. I might not ever do so, but I well may. I am so incredibly pleased that if I do so, I will have the option of a synthetic. I already take pain killers in tablet form when I take them, rather than gel-caps, to avoid the gelatin. But when you get to less common drugs you tend to have fewer options for the format in which you take them or the source. Knowing I won't need to eat bits of pig every day to deal with a thyroid problem is a huge relief to me.
