I have been exceptionally tired lately. Admittedly, attempting to hold my new schedule hasn’t gone smoothly & I have an all-you-can-eat stress buffet at work, but I still feel that I have been especially lethargic. I suspect it may be my thyroid.
Like a pandemically large number of people (27 million Americans + another estimated 10%undiagnosed), I have been diagnosed with hypothyroidism & prescribed the synthetic & generic levothyroxin, which I have just discovered uses gluten as a filler!?!?!? & has a normal variance of +/- 10% in potency from one pill to the next, which seems dangerous. After extensive research & 3 recent blood tests, I have permanently switched to the natural porcine Armour Thyroid.
After further research, as of this morning, I have also switched from the typical doctor recommendation of taking thyroid medication in the morning to taking thyroid medication at night.
a 2007 study published in the journal Clinical Endocrinology, and a follow-up larger randomized trial reported in the December 2010 issue of the Archives of Internal Medicine – have found that taking the same dose of levothyroxine (i.e., Synthroid) at bedtime, as compared to first thing in the morning, may be better.
The researchers suggested several explanations for the results:
- Even when waiting at least 30 minutes to eat, breakfast may be interfering with the intestinal absorption of levothyroxine thyroxine.
- “Bowel motility is slower at night,” which means that it takes longer for the levothyroxine tablet to transit through the intestinal system, resulting in longer exposure to the intestinal wall, and therefore, better uptake of the medication.
- The conversion process of T4 to T3 may be more effective in the evening.
